2 What is GIS? GIS Geographic Information System What and where Everything is somewhere Computer mapping tool. A GIS is a computer program that allows multiple layers of information to be displayed simultaneously with each layer/feature displayed relative to its location on the surface of the earth. Functions much like a hardcopy map with various overlays containing additional data but in a GIS the data that can be associated with a feature is virtually unlimited. The GIS is a tool bridging the gap between where and what something is. 2

3 Before GIS Cloth or linen maps One or more maps for each county plus field maps Typical scales 1 = = 4000 Hand posted wells Problems? Prior to the implementation of GIS at the Railroad Commission (RRC) all well locations were tracked using hardcopy cloth or linen maps. A minimum of one map exists for each of the 254 counties with many of the large counties consisting of 2 or more maps. Due to the scale of the maps only a limited amount of information can be added to a given area. In areas of high well density field maps were created to show a specific area in greater detail. When a new well needed to be added to the map a technician would obtain the permitting information submitted for a well, select the necessary map and use a scale bar to spot the well on the map using the provided survey line calls. 3

4 Before GIS Tracking well locations using hardcopy maps has various problems and limitations. One of the major limitations is availability and/or accessibility. - The maps are housed in the RRC Austin office and only accessible in person. - Many of the maps are copyrighted and cannot be copied or disseminated. Some of the significant problems with hardcopy maps are wear and scale of the maps. - Hardcopy maps eventually wear out. Over time the information can be worn off, smudged, overwritten or inadvertently altered. - Limitation information can be added to hardcopy maps. Even in area with moderate well density adding enough information to allow the well spot to be linked with well documents presents a challenge and in area of high well density adding the appropriate information can become almost unmanageable. - The scale presents a problem because the size of the dot representing the well can easily be greater than 100 which in turn can lead to misinterpretation of the well location or the information associated with it. 4

5 Current GIS Railroad Commission generated and maintained survey and well layer > 1,300,000 wells > 311, 000 survey polygons > 1, 042,000 survey lines Changes and additions made on a daily basis New information updated nightly The creation of the Railroad Commission GIS viewer consisted of 2 main layers, the wells and the underlying base map. This was a 10 plus year process beginning in 1984 and completed in Survey lines and attributes were built from the Texas General Land Office (GLO)Original Texas Land Survey maps (OTLS) and the Land Title Index (LTI). The wells were then transferred from the linen and field maps by digitizing each well individually. Changes to surveys, well locations and additional features occur on a daily basis with the new information updated nightly to the public GIS viewer. Additional layers such as pipelines, LPG/CNG/LNG sites and operator cleanup program sites have been added over time. 5

6 GIS/Well Mapping Department Maintain basemap layers Edit or add survey lines Update well symbols Forms W-2, G-1, W-3, P-4 Correct well locations Well spot or API number discrepancy Remove erroneous well spots Update API for historic well Documents need to be provided The GIS/Well Mapping department is responsible for maintaining the survey basemap and well layers. Changes are made using a variety of commission forms as well as information provided byoperators,other state agencies and independent sources. 6

7 GIS Viewer Links The GIS viewer page can be accessed two different ways from the RRC homepage. 1. Click on Resource Center on the top of the page and click on Public GIS Viewer (Map) under the research section. 2. Click on the Maps Public GIS Viewer link under useful links on the right hand side of the RRC homepage. Using either method will navigate to the same page. 7

8 GIS Viewer To launch the viewer click on the map screenshot or click the Launch Public GIS Viewer link. This page also contains training videos and contact information for the various departments that can provide additional information about the features found in the GIS. 8

9 GIS Viewer Load Screen After launching the viewer there a 7 sections/items that comprise the GIS viewer. The public GIS viewer screen contains the following items: 1) Toolbar - Located across the top of the screen containing all the interactive tools. 2) Legend/Visibility Pane -Located on the left hand side of the screen this displays the available layers and associated legend. 3) Zoom Control Allows you to zoom in or out on the map. The scroll wheel on the mouse can also be used to zoom in and out. 4) Dynamic Coordinates Displays the geographic coordinates (WGS 84) for the location of the cursor on the map. 5) RRC Logo/button Opens the Railroad Commission homepage by clicking on the logo. 6) Viewing Pane displays the map and layers available at the current scale. 7) Screen Overview Displays the area you are viewing and the surrounding area at a smaller scale. 9

10 Visibility Displays the available layers Layers are scale dependent Only one highlight can be applied at a time Layer must be turned on to identify feature The visibility pane contains all of the available features that can be turned on or off by the user. - Layers are scale dependent so even if the box is checked that feature may not display on the map at the current scale. - Well highlights can be applied by checking the box associated with the desired highlight. o Highlight consists of a colored halo placed around the well location. o Only one highlight can be applied at a time. The identify tool can only access layers/features that are turned on in the visibility pane. Visibility window can be closed by clicking the white X in the upper right hand corner and reopened by clicking the visibility button on the toolbar. 10

11 Legend Information about symbols on the map Legend items dependent on visibility selection Legend is scale dependent The legend provides a description for each of the symbols on the map. Two conditions must be met for the symbols to appear in the legend. 1) The layer must be turned on in the visibility pane. 2) The map scale must be such that the layer will display on the map. A PDF of all symbols can be accessed by clicking the printable legend link in the upper right hand corner of the legend. Legend window can be closed by clicking the white X in the upper right hand corner and reopened by clicking the legend button on the toolbar. 11

12 Select County and Print Navigate to a specific county Print PDF or PNG format Printout will open in new tab Cannot specify a scale To navigate to an county select the county from the dropdown. To print, click the white arrow to the right of the print icon and select the desired paper orientation and file type. - The scale will be automatically selected and specific scales cannot be applied. - The Print tool should change from Print to Printing while the file is being built. - The file will open in an additional tab after the process is complete. - Pop up blocker must be turned off for the file to open. - Based on the aspect ratio of the monitor and the paper orientation selected the entire area shown on the screen may not be included in in the printout. 12

13 Find well API or Address API can be entered with or without dash API must include 8 digits FIPS and unique identifier Viewer will navigate to well and highlight in cyan Highlight must be removed before identifying well Use Clear Graphics to remove highlight Addresses can be used to navigate but are best used to navigate to general areas. The API is the best way to navigate to a location. It can be entered with or without the dash but must include the FIPS and unique identifier (8 digits). A complete API number consists of 10 digits The first 2 digits (42) represent the state (Texas= 42) and are omitted when preforming a API search on the RRC website. - The 3 digits (123) represent the FIPS code which is specific to the county in which the well is located. - The last 5 digits (45678) is the unique identifier for the well in its respective county. The viewer willnavigatetothewellandhighlight inthelocationincyan. - The highlight must be removed before identifying the well. The identify results will not open properly if the highlight is not removed. 13

14 Switch Basemap Change underlying map The basemapcan be changed to one of 12 options. The basemapsare hosted services provided by ESRI and are not maintained by the Railroad Commission. 14

15 Measure Various measurement types Area Distance Location Single click to begin and double click to end Units can be changed at any time To use the measurement tools click on the measure tool in the toolbar and click on the appropriate measurement tool inside the window to activate it. - Active tool will have a grey background, if no tool is selected the measurement functionality will not work. - Click one time on the map to begin the measurement, each single click will add a vertex and double click willend the measurement. - The unit can be changed before or after making a measurement. - The coordinate results are WGS

16 Identify Locate information about features Layer must be turned on Toolbar will show what features can be identified Click on feature after small pop up appears Results display in pop up window The identify functionality is used to locate additional information about features shown in the GIS. To activate the identify functionality click on the identify tool and select the appropriate feature from the dropdown. Click on the corresponding feature in the GIS and a second window will open with additional identify results. - Results vary depending on the feature being identified some examples are permit numbers, API numbers, lease information, status, production, commodity, historical documents, etc. - Some results require you to click on additional links to access more information. 16

17 Identify Results API Geographic information Links to other queries Operator/Wellbore Information from most recent approved drilling permit Completion Record Current and historical records Links to production and hardcopy records The identify results for well locations are broken down into three sections. The API section contains information about characteristics of the well and the geographic location. - The GIS location source which provides the source data for the well which determines its reliability. See the well reliability handout for a list of GIS location sources. - Links to well logs, drilling permits and disposal permits. The operator/wellbore section contains drilling permit information for last drilling permit filed for the well. - Oil/Gas Imaged Records for API:XXX-XXXX is a link to hardcopy neubusrecords for the identified API. Multiple lease ID numbers could be present in the neubus records. The completion record section contains information specific to the current and/or historical completions for the well. - Can contain a single or multiple records. - Production DataQuery(PDQ) link opens the PDQ query for the lease ID under which the link is located. - Oil/Gas Imaged Records for Lease/ID:XXXXX is a link to hardcopy neubus records for the identified lease/id number. 17

19 Coordinates Coordinate system selection is important Geographic Coordinate Systems NAD 27, NAD 83, WGS 84 2 input options Degrees Minutes Seconds o , Decimal Degrees o , Negative is required on longitude NAD 27 vs NAD 83 ~75 East Texas ~170 West Texas When using coordinates to identify a location it is important to pay close attention to the coordinate system of the source information. - The correct selection must be made in the GIS viewer. - The GIS viewer accepts either geographic or state plane coordinates. Geographic Coordinate Systems - The geographic coordinate system consists of two angular measurements which when combined identify a specific point on the earths surface. o The GIS viewer will accept latitude and longitude coordinates referencing NAD27, NAD 83 and WGS84 datums. o Coordinates can be entered in degrees minutes and seconds (DMS) or decimal degrees. o Placeaspacebetweeneachvaluewhenentering indms. o All locations in Texas will always consist of a positive latitude and negative longitude measurement. o Coordinates should always be entered in their specified datum because using the incorrect datum will result in inaccurate placement. 19

20 Coordinates State Plane Coordinate Systems NAD 27 and NAD 83 5 Zones in Texas North, North Central, Central, South Central, South Zones run East-West Coordinates always positive To use you must know Datum Zone Measurement Texas state plane coordinates. - Texas is divided into five zones from the panhandle to south Texas with each zone running easttowest. - State plane coordinate systems are planar systems with coordinates that originate from a false northing and false easting point and therefore the coordinate values will always be positive. - Both NAD27 and NAD83 state plane coordinates can be used but it is important to note the NAD 83 coordinates must be in feet. - To use state plane coordinates you must know the datum, zone and the measurement. o The measurements are not interchangeable between datums because the point of origin for each datum is different. 20

21 State Plane Zones The five state plane zones of Texas begin in the panhandle and end in south Texas. Each zone has a unique name and FIPS or numerical identifier. From north to south they are - FIPS 4201, TX-North - FIPS 4202, TX-North Central - FIPS 4203, TX-Central - FIPS 4204, TX-South Central - FIPS 4205, TX-South 21

22 Coordinates Geographic Coordinates Degrees Minutes Seconds , Decimal Degrees , State Plane X = , Y = (NAD 27 TXSC) Select the coordinate system first then enter the coordinate values. Examples of how the coordinate values should be entered are shown above. - Place a space between each value when using Degrees Minutes Seconds. 22

23 Coordinates Flag appears to move Flag remains the same size Map changes scale Anchor point is not the base of flagpole Anchor point is center of flag When working with coordinates in the GIS viewer it is important to note the location of the anchor point for the flag symbol used to represent the coordinate location. The anchor point is the location within the flag symbol that is tied to the coordinate location entered. The anchor point is in the center of the triangular shaped flag not at the base of the flag pole As you zoom in and out the location of the flag map appear to change however the anchor point of the flag remains in the same location and the size of the flag symbol remains the same but the map changes scale underneath the flag. The flagappearstomovebecauseasthe map scale is getssmaller the flag symbol occupies more area on the map making it appear the base of the flag is moving. This appearance is more pronounced the smaller the map scale. 23

24 Pipeline Search Not all attributes need to be entered Selected results highlighted on map Pan within map to find selected results Use clear graphics to remove highlight The pipeline search feature queries pipeline attributes based on user defined criteria - Alist of matching results is returned and highlighted on the map. - Pan within the map to view highlighted results. Pipeline location and attributes are maintained by the pipeline mapping unit which is part of the pipeline safety divisions. - Inquires regarding pipelines should be directed to tpms@rrc.texas.gov or

25 Survey Search Not all attributes need to be entered Results highlighted on map and zooms to first result Partial survey names can be entered Spelling, punctuation and spaces are important Use clear graphics to remove highlight The survey search feature allows the user to query survey basemapinformation. - To use the survey search select the county and enter the attributes. - Not all information must be completed. o More information results more concise list of results. - Alist of surveys matching the criteria is generated and the viewer navigates to the first record on the list. o If multiple records exist use the Click to Zoom to button on the left hand side to navigate to and highlight a specific result. 25

26 Lease Search Lease ID must be entered 5 digit oil ID All wells on the lease will be displayed 6 digit gas ID Only the gas well under the ID will be displayed District is optional Oil ID may repeat in different districts Click API to navigate to the well Use clear graphics to remove highlight The lease ID search can be used to generate a list of wells that are or have been under a specific lease ID. Oil lease ID numbers can repeat in different districts therefore if the district is not entered all wells under the ID regardless of district will appear in the results. Gas ID numbers are specific to each well and will not repeat so the district is not required. Enter the lease ID and if desired the RRC districttogeneratethelist. - To navigate to a specific well click on the API number in the query results. 26

27 Radius Enter buffer size Must be in miles Click map to draw Multiple radii can be displayed Use clear graphics to remove radii All radii will be removed The radius tool can be used to generate a graphic on the map representing a specified distance around a location. The tool can generate multiple radii that can be placed at the same or different locations. The tool does not snap to a specific locations so it is recommended to zoom in as close a possible prior to clicking to add the graphic. 27
