2 Wassuk Range NV LANDFIRE Application Project GIS Analysis & Metadata Documentation The Nature Conservancy of Nevada December 2007 Contained within this document are detailed notes regarding GIS work for the Wassuk Range NV LANDFIRE Application Project. Work includes (a) preparation or manipulation of various GIS datasets, (b) acquisition of LANDFIRE National and Rapid Assessment data, (c) use of the FRCC Mapping Tool and other LANDFIRE software to generate FRCC data, and (c) comparison of FRCC and BpS datasets between LOCAL and LANDFIRE data. Location of data, metadata and other files for this (and related) project on TNC-NV s GIS drive (K:): K:\GIS1\landfire Specifically K:\GIS1\landfire\data K:\GIS1\landfire\geodata K:\GIS1\landfire\geodata\albersnad83\NationalData K:\GIS1\landfire\geodata\albersnad83\RapidAssessment_Sept2006 K:\GIS1\landfire\geodata\albersnad83\wassukap K:\GIS1\landfire\geodata\test K:\GIS1\landfire\geodata\utm11nad27\wassukap K:\GIS1\landfire\gis_tools K:\GIS1\landfire\maps K:\GIS1\landfire\metadata K:\GIS1\landfire\projects K:\GIS1\landfire\reports K:\GIS1\landfire\training - non-spatial data: refcon tables, cross-walks - GIS data - DVD data of LANDFIRE National Data - CD data of LANDFIRE Rapid Assessment - LANDFIRE data for this App Project - preliminary data for this App Project - LANDFIRE/local data for this App Project - various software tools - PDF maps - documentation - Arc projects - completed product: this document - training documents, exercises; notes Note: Throughout this document, various GIS datasets are described visually through maps; tabularly through Value Attribute Tables (VATs) or Excel spreadsheets; or, textually through properties descriptions. Appendix 3 contains much of this information. Note: This document is a Microsoft Word file. Since created as a Word file, various sections (maps, in particular) are clipboard insertions into the document. In some instances (maps, in particular), the visual/print quality is reduced relative to the original source because of this. Task I: Preparation of key GIS datasets. Methods: Use ESRI s ArcInfo 9.0 Workstation and ArcView ArcMap 9.1. I.1. The local data to compare against the LANDFIRE data are in the UTM Zone 11 NAD27 coordinate system. In order to download the LANDFIRE data (which are Albers NAD83), the raster grid for the project boundary needs to be reprojected (whole project boundary and west-east basins boundary). To accomplish this, a series of data manipulations were performed: a. Copy the 2 grids to keep the originals intact. b. Make the background NoData. c. Resample the 2 grids from 10 meters to 30 m. Wassuk Range NV LANDFIRE Application Project GIS Analysis & Metadata.doc 2/134

3 I.1.A. The whole project boundary (WASSUK) and the 2-basins (west-east) boundary (BASINS) were copied using ArcInfo 9.0 Workstation: K:\GIS1\landfire\geodata\utm11nad27\wassukap\local\FRCC\ WASSUK - whole Wassuk Range NV LANDFIRE Application Project boundary BASINS - east and west basins for the project boundary Usage: COPY <from_geo_dataset> {to_geo_dataset} {DEFAULT SINGLE DOUBLE} Arc: copy wassuk wassuk2 Arc: copy basins basins2 Descriptions of the 2 original raster grids: WASSUK.VAT Value Count Notes Background Project Area BASINS.VAT Value Count Class_name Basins Notes Background Background Basin - West WEST Project Area Basin - East EAST Project Area Wassuk Range NV LANDFIRE Application Project GIS Analysis & Metadata.doc 3/134

4 Note: There are some weird raster cell slivers in at least 2 south-central portions on the edges of both WASSUK and BASINS. Some of these slivers disappear in WASSUK2 and BASINS2 (after the resampling, etc). Note: There are cell changes that occur in the raster grids as the datasets are manipulated (e.g., resampling, reprojecting). I.1.B. Using ArcMap 9.1, the background raster cells were disappeared. WASSUK and BASINS had Value = 0 for the background (the non-project area). In WASSUK2 and BASINS2, the background in each was converted to NoData using the Reclassify tool (ArcToolbox Spatial Analyst Tools Reclass Reclassify).

6 Note: At each step, the resulting grid was renamed WASSUK2 or BASINS2 and the intermediary grid was deleted using Arc:rename and Arc:kill. I.1. C. The original landscape level boundaries, WASSUK and BASINS, are raster grids with a cell size 10m. In order to make WASSUK2 and BASINS2 the same 30m cell size of LANDFIRE data, these grids were resampled using ArcMap s Resample tool (ArcToolbox Data Management Tools Raster Resample).

8 Note: At each step, the resulting grid was renamed WASSUK2 or BASINS2 and the intermediary grid was deleted. The final WASSUK2 and BASINS2 project boundaries in UTM Zone 11 NAD27 are described here: K:\GIS1\landfire\geodata\utm11nad27\wassukap\local\FRCC WASSUK2 BASINS2 WASSUK2.VAT Value Count BASINS2.VAT Value Count Notes West East In a 30 meter raster grid, each cell is 900 m 2 or acres. Acres = (Area in square meters / 10,000) * To determine size of the Wassuk Range project area, Acres = Count * Wassuk Range project area = 346, acres West basins area = 192, acres East basins area = 153, I.2. Reproject the 2 project boundary (landscape level) grids from UTM 11 NAD27 to Albers NAD83. I.2.A. A two-step reprojection was performed: WASSUK2 and BASINS2 were reprojected first from UTM 11 NAD27 to UTM 11 NAD83 and second from UTM11NAD83 to Albers NAD83 (USA Contiguous Albers Equal Area Conic USGS.prj) using ArcMap s Project Raster tool (ArcToolbox Data Management Tools Projections and Transformations Raster Project Raster). (The intermediary data was deleted.) Resultant datasets: K:\GIS1\landfire\geodata\albersnad83\wassukap WASSUK2 BASINS2 Wassuk Range NV LANDFIRE Application Project GIS Analysis & Metadata.doc 8/134

9 Wassuk Range NV LANDFIRE Application Project GIS Analysis & Metadata.doc 9/134

10 I.2.B. Note: After the reprojection, the WASSUK2 and BASINS2 landscape level grids each had a cell size of meters rather than 30 meters. To deal with this, the two grids were resampled to 30 meters using ArcMap s Resample tool (ArcToolbox Data Management Tools Raster Resample). Resultant datasets final for use as landscape level grids (in the Albers NAD83 coordinate system): K:\GIS1\landfire\geodata\albersnad83\wassukap WASSUK2B BASINS2B Dataset descriptions are below. Note the difference in cell count between these reprojected grids and their originals. Note the overall shape difference (project boundary) between the two coordinate systems.

12 Task II: Acquire LANDFIRE National Data and LANDFIRE Rapid Assessment data. Methods: Use the LANDFIRE Data Access Tool. From ArcMap 9.1, LANDFIRE National and LANDFIRE Rapid Assessment BPS and SCLASS data were downloaded using the LANDFIRE Data Access Tool (LDAT) The WASSUK2B project boundary (in Albers NAD83) was used as the reference boundary for the data download. The Wassuk Range NV Application Project lies entirely within LANDFIRE Map Zone 12 - Western Great Basin. II.1.

II.2. Prepare GIS datasets for use in the FRCC Mapping Tool. II.2.A. Though it is not necessary to clip the BPS and SCLASS layers to the landscape level (WASSUK2B) for use in the FRCC MT, to simplify matters (especially given that the downloads included Map Zone 12 as well as an extraneous bit of Map Zone 6), the datasets were clipped to the project boundary. Using the Spatial Analyst Raster Calculator, each of the BPS and SCLASS datasets for both LANDFIRE National and Rapid Assessment were clipped to the project boundary (analysis mask = WASSUK2B).

19 LANDFIRE Rapid Assessment data II.2.B. Because the clipping process removes most of the attribute information associated with the raster grids (everything but the Value and Count fields (and the ObjectID field)), the LANDFIRE Join Attributes tool was used to restore their attributes. The LANDFIRE Join Attributes Tool was used to add back the attribute information to the BPS and SCLASS data layers (for National and Rapid Assessment). The process creates a new grid (renamed *2 for all datasets using Arc:rename). These data layers are the ones to use with the FRCC Mapping Tool. II.2.C.

54 Task IV: Compare LOCAL BpS and FRCC data with (1) LANDFIRE National Data and (2) LANDFIRE Rapid Assessment data. Methods: ESRI ArcMap 9.1 raster tools and ArcInfo 9.0. The Wassuk Range NV LANDFIRE Application Project is, fundamentally, a data comparison (or accuracy assessment) between (1) the LOCAL vegetation (or biophysical setting - BpS) and fire regime condition class (FRCC) data and either (2A) the LANDFIRE National or (2B) the LANDFIRE Rapid Assessment BpS and FRCC data. The LOCAL data is the same spatial scale/resolution 30 meters as the LANDFIRE data, but the LOCAL data can be considered the most accurate because of the concentrated work involved in developing the project-scale data, especially the ground-truthing field work. Using ArcMap 9.1 and ArcInfo 9.0, (A) the LOCAL and LANDFIRE BpS data are compared, (B) the LOCAL and LANDFIRE FRCC (stratafrcc) data are compared, and (C) for a given BpS, the FRCC (stratafrcc) LOCAL and LANDFIRE data are compared. In order to compare the LOCAL and LANDFIRE data, (1) the raster grids all need to be in the same coordinate system, (2) the raster grids all need to have the same 30-meter cell size, and (3) all FRCC (strata) grids need all cells within the project boundary to be accounted (FRCC values 1,2,3 as well as non-frcc value 4). Wassuk Range NV LANDFIRE Application Project GIS Analysis & Metadata.doc 54/134

55 Ideally, to ensure highly accurate cell-by-cell comparisons among raster grids, all grids will be perfectly aligned (not simply in the same coordinate system). In other words, when stacked on top of one another, every cell representing a real-life point on the planet will exactly correspond to the same cell (and same reference point) in every other grid. The LANDFIRE grids (at least in their native Albers NAD83) should align with one another. The main issue is aligning the LOCAL and LANDFIRE grids (with every raster being in UTM11 NAD27). Close-up examination of random areas of the grids reveals that the rasters are slightly off relative to one another. Whether or not this will in any way affect BpS/FRCC comparisons is not clear. (Additionally, snapping grids into cell alignment presumes it can be determined which cells correspond among grids not something necessarily easy to determine.) However, TNC believes that the cell alignment issue will not significantly impact grid comparisons for these larger-area Application Projects (see Appendix 1). At this time, the LOCAL and LANDFIRE BpS and FRCC grids have not specifically been adjusted in this manner. Example: LOCAL BpS grid (BPS_LND2) versus LND BpS grid (BPSWR2_LOC) in upper-left corner of Wassuk Range project area; data is UTM 11 NAD27 (on left LOCAL is on top; on right LND is on top). Note: In the comparison of LOCAL BpS with LND BpS, the combined grid (BPS_LC_LND) appears to align with the LOCAL grid (which was the first grid chosen for the Combine) and the LND grid is slightly off. Note: When doing data comparisons using ArcMap s Combine tool, for any given geographic point, any NoData cell in any grid in the Combine results in a NoData cell in the output (which will impact cell counts and other things).

56 Task IV.1. Comparison of LOCAL and LANDFIRE BpS data. The biophysical (vegetation) data developed for the Wassuk Range (i.e., LOCAL data) was compared to the LANDFIRE data (both LND and LRA). Using ArcMap raster tools, a comparison was made to determine how well the LOCAL and LANDFIRE BpS data match on a cell-by-cell basis. In order to compare the different BpS data, some kind of cross-walk was needed. Louis Provencher reviewed the local, LANDFIRE National, and LANDFIRE Rapid Assessment BpSs found in the Wassuk Range NV. The following cross-walk tables were developed. All BpS grids were reclassified in order to be compared, and all grids use the Cross-Walk Code for cell Values.

All BpS types (as well as non-bps cells like Water) are accounted for in both local and LANDFIRE data. In other words, all cells are categorized as something; none were converted to NoData. 2. The FRCC MT creates clean BpS grids -- these were not used for BpS map comparisons; the original BpS grids were used. 3. The Cross-Walk Code was designed to help distinguish, at a glance, (a) BpSs which are the same/similar between local and LANDFIRE (or at least were assigned a match) characterized by the four-digit BpS_Code (based upon LND codes even for LRA PNVG/BpS). (b) BpSs which are from LANDFIRE but not local data characterized by BpS_Model (map zone 12 followed by the four-digit BpS_Code) (based upon LND Codes even for LRA PNVG/BpS). (c) BpSs which are from local data but not LANDFIRE characterized by 90 (arbitrary code) followed by the four-digit BpS_Code (based on LND BpS codes even for LRA PNVG/BpS). Note: There is the possibility that there are existing LANDIFRE BpS matching local BpS, but they were Wassuk Range NV LANDFIRE Application Project GIS Analysis & Metadata.doc 57/134

58 not represented in the Wassuk Range. (d) One local BpS (1080) is split into three types, and in the LOCAL LRA cross-walk these three types are maintained and use the BpS_Code followed by an extra digit (10800, 10801, 10802). (e) Non-BpSs from both local and LANDFIRE data were given two-digit codes. Two (11 Water; 31 Barren- Rock/Sand/Clay) use LND-based codes. The rest (e.g., 60 Agriculture) are arbitrary. 4. In BpS_Model (example: Inter-Mountain Basins Big Sagebrush Shrubland), the first two digits represent Map Zone, the next four digits represent BpS_Code, and the last digit is agency status of BpS. In the cross-walks above, the last digit was not used in any of the Cross-Walk Codes. LOCAL Data preparation: * For comparison with LANDFIRE National Data, the local BPS grid was reclassified with the Cross-Walk Code and named BPS_LND. The Reclassify tool in ArcMap 9.1 was utilized (ArcToolbox Spatial Analyst Tools Reclass Reclassify). The Background (Value 0) was made NoData; whatever cells were NoData remain NoData; the rest of the cells conform to the Local LND cross-walk. * For comparison with LANDFIRE Rapid Assessment, the local BPS grid was reclassified with the Cross-Walk Code and named BPS_LRA. The Reclassify tool in ArcMap 9.1 was utilized. The Background (Value 0) was made NoData; whatever cells were NoData remain NoData; the rest of the cells conform to the Local LRA cross-walk.

First, the grid was reprojected to UTM11 NAD83, then the intermediary dataset was reprojected to UTM11 NAD27. The intermediary grid (which was deleted) had a cell size of meters (rather than the inputted 30 meters). However, during the second phase of the reprojection process, the cell size became 30 meters.

64 LOCAL LND BpS Comparison How well do the LOCAL BpS and LANDFIRE National BpS compare (i.e., match) on a cell-by-cell basis? To determine this and to have a grid which would display this, the raster grids were Combined in ArcMap 9.1 (ArcToolbox Spatial Analyst Tools Local Combine). The LOCAL LND combined BpS grid: K:\GIS1\landfire\geodata\utm11nad27\wassukap\compare BPS_LC_LND BPS_LC_LND represents 237 combinations of LOCAL and LND BpS. The following 13 Values represent cell matches between the LOCAL and NATIONAL BpS: 2, 5, 10, 34, 40, 46, 52, 87, 96, 137, 155, 185, 210. Note: One of above matches is Water. In a cell-to-cell comparison between LOCAL and LND BpS, there is a % match: BPS_LC_LND: cell count of 13 matching Values / total cell count = / = %.

77 Task IV.2. Comparison of LOCAL and LANDFIRE FRCC (stratafrcc) data. Fire Regime Condition Class (FRCC) data were developed for the Wassuk Range using (a) Local, (b) LND and (c) LRA inputs for BpS, SClass, and Reference Conditions at both (i) project and (ii) west & east basins scales/areas. The LANDFIRE FRCC Mapping Tool generated the FRCC data. The FRCC MT creates several different FRCC outputs. Only the STRATAFRCC were used in this analysis. With ArcMap s raster tools, a comparison was made to determine how well the LOCAL and (A) LND or (B) LRA FRCC data match on a cell-by-cell basis. FRCC Values are 1, 2 and 3. Value 4 represents cells that do not have an actual FRCC value. The LOCAL FRCC data contains all 4 Values. The LANDFIRE data created by the FRCC MT only have Values 1,2,3; there are holes where the Value 4 would ostensibly be. (Any other reason to account for the holes; like, for example, the fact that while BPS data typically have valid Values for all cells within a project area, SCLASS data often do not?.) Ideally, all STRATAFRCC data will have Values 1,2,3,4 in order to account for all cells and to perform a more thorough analysis. LOCAL Data Preparation: Local Project * The local STRATFRCC data for the project area has Values 1, 2, 3 and 4. Values 1, 2 and 3 correspond to FRCC 1, 2 and 3, respectively. Value 4 is the non-frcc class (and is called -99 in the STRATFRCC field). In this dataset, Value 4 represents, ostensibly, the non-frcc within the project area, but it also represents the background beyond the project boundary. To deal with this, the grid needs to be clipped to the project boundary. First, the project boundary needed to have its background removed using the Reclassify tool. The 10-meter grid WASSUK thus became WASSUKB by making the background (Value 0) NoData. Next, STRATFRCC was clipped to WASSUKB using the Raster Calculator resulting in STRATFRCCB. So Wassuk Range NV LANDFIRE Application Project GIS Analysis & Metadata.doc 77/134

78 Finally, STRATFRCCB was Resampled to 30 meters and called STRATFRCC3 (see ## note below). The final grid for use in the data comparisons: K:\GIS1\landfire\geodata\utm11nad27\wassukap\local\FRCC\OUT4 STRATFRCC3 STRATFRCC.VAT Value Count Stratfrcc STRATFRCCB.VAT Value Count STRATFRCC3.VAT Value Count ## Note: Originally, the final grid was named STRATFRCC2. However, running the Combine tool with grids having the same name produces bad results. Do NOT Combine grids with the same name. To differentiate among the various STRATFRCC grids used in the data comparisons, sequential numbers (2, 3, etc) were randomly applied to the grid names. Hence, STRATFRCC3 (when there is no STRATFRCC2). Local Basins * The local STRATFRCC has Values 1, 2, 3 and 4. Values 1, 2 and 3 represent FRCC 1, 2 and 3, respectively. Value 4 is the non-frcc class (and is -99 in the STRATFRCC field). In this dataset, Value 4 represents non- FRCC cells as well as the background, so it needs to be clipped to the project boundary. First, STRATFRCC was clipped to WASSUKB using the Raster Calculator resulting in STRATFRCCB. Next, STRATFRCCB was Resampled to 30 meters and named STRATFRCC4. The final grid for use in the data comparisons: K:\GIS1\landfire\geodata\utm11nad27\wassukap\local\FRCC\OUT2 STRATFRCC4 STRATFRCC.VAT Value Count Stratfrcc STRATFRCCB.VAT Value Count STRATFRCC4.VAT Value Count Wassuk Range NV LANDFIRE Application Project GIS Analysis & Metadata.doc 78/134

79 LANDFIRE National data preparation: LND Project * The LND STRATAFRCC dataset for the project area has Values 1, 2 and 3 corresponding to FRCC 1, 2 and 3, respectively. However, the dataset does not contain the Value 4 for non-frcc. To get em back, the grid will be Reclassified so that NoData is changed to Value 4, then the resulting grid will be clipped to the project boundary. Finally, the data needs to be reprojected from Albers NAD83 to UTM Zone 11 NAD27. First, using ArcMap s Reclassify tool, STRATAFRCC NoData cells were changed to Value 4 and the new grid was named STRATFRCCB. Second, STRATFRCCB was clipped to WASSUK2B using the Raster Calculator and the resulting grid was named STRATFRCC2. So STRATAFRCC.VAT Value Count Stratafrcc STRATFRCCB.VAT Value Count STRATFRCC2.VAT Value Count Finally, STRATFRCC2 was reprojected via a two-step process to UTM11 NAD27 and the final grid was also named STRATFRCC2. Again, the intermediary grid had a cell size of , but in the second phase of reprojection the grid was 30 meters.

First, using the Reclassify tool, STRATAFRCC NoData cells were changed to Value 4 and the new grid was named STRATFRCCB. Second, STRATFRCCB was clipped to WASSUK2B using the Raster Calculator to create STRATFRCC5. STRATAFRCC.VAT Value Count Stratafrcc STRATFRCCB.VAT Value Count STRATFRCC5.VAT Value Count Finally, STRATFRCC5 was 2-step reprojected (ArcMap Project Raster) and the output was also named STRATFRCC5.

81 LANDFIRE Rapid Assessment data preparation: LRA Project * The LRA STRATAFRCC has Values 1, 2 and 3 which correspond to FRCC 1, 2 and 3, respectively. However, the dataset does not include the non-frcc Value 4. Using the Reclassify tool, STRATAFRCC NoData cells were changed to Value 4, and the new grid was named STRATFRCCB. STRATFRCCB was then clipped to WASSUK2B using the Raster Calculator to create STRATFRCC6. STRATAFRCC.VAT Value Count Stratafrcc STRATFRCCB.VAT Value Count STRATFRCC6.VAT Value Count STRATFRCC6 was reprojected (ArcMap Project Raster) via a 2-step process from Albers NAD83 to UTM 11 NAD27. The reprojected grid was also (re)named STRATFRCC6. The intermediary grid had a cell size of meters even though 30 m was inputted as the cell size. The final grid has a 30m cell.

Since Value 4 (non-frcc) cells are not in this dataset, they needed to be recovered. STRATFRCC was Reclassifed so that NoData cells became Value 4 and the output was named STRATFRCCB. Next, STRATFRCCB was clipped to WASSUK2B to create STRATFRCC7.

87 Task IV.3. LOCAL LANDFIRE Joint BpS & FRCC Data Comparisons Data comparison: LOCAL versus LND or LRA. For a given BpS, for those cells which match between LOCAL and LANDFIRE, how well do the FRCC match (at both project and basins scales)? Note: These grid comparisons utilize a Combine of the cross-walked, combined LOCAL-LANDFIRE BpS and the combined LOCAL-LANDIFRE FRCC. The FRCC were generated with separate Local, LND or LRA BpS (and other) inputs. The combined BpS represents the cross-walked BpS rather than the original. The presumption is that the cross-walked BpS is effectively the same as the original BpS; therefore, it is appropriate to use these combined BpS grids in this set of data comparisons. Methodology: Step 1. Use the combined LOCAL-LANDFIRE BpS grid. Local LND: BPS_LC_LND (12 BpS matches not counting Water) Local LRA: BPS_LC_LRA (7 BpS matches not counting Water) Step 2. Reclassify so all cells - except for one BpS and the one Value that is a match - are NoData. Output grid nomenclature: Local LND: BPSCN#### (BPS local-lnd 4-digit bps_code) Local LRA: BPSCR#### (BPS local-lra 4-digit bps_code) Step 3. Combine this BpS grid with the combined LOCAL-LANDFIRE FRCC grid. Local LND (project): FC_LC_ND_W Local LND (basins): FC_LC_ND_B Local LRA (project): FC_LC_RA_W Local LRA (basins): FC_LC_RA_B Step 4. The output grid provides the data comparison: for a given BpS matched between Local and LANDFIRE datasets, how well do the FRCC cells match? Output grid nomenclature: Local LND (project): BFCNW#### (Bps-Frcc local-lnd Wassuk-level 4-digit bps_code) Local LND (basins): BFCNB#### (Bps-Frcc local-lnd Basins-level 4-digit bps_code) Local LRA (project): BFCRW#### (Bps-Frcc local-lra Wassuk-level 4-digit bps_code) Local LRA (basins): BFCRB#### (Bps-Frcc local-lra Basins-level 4-digit bps_code) Output: Local LND (project) K:\GIS1\landfire\geodata\utm11nad27\wassukap\compare\bpsfrcc\local_lnd\wassuk Local LND (basins) K:\GIS1\landfire\geodata\utm11nad27\wassukap\compare\bpsfrcc\local_lnd\basins Local LRA (project) K:\GIS1\landfire\geodata\utm11nad27\wassukap\compare\bpsfrcc\local_lra\wassuk Local LRA (basins) K:\GIS1\landfire\geodata\utm11nad27\wassukap\compare\bpsfrcc\local_lra\basins Wassuk Range NV LANDFIRE Application Project GIS Analysis & Metadata.doc 87/134
