Environmental Hazard & Safety Facility Mapping Using Data Driven Pages Kathi Cotney, GISP Lead Consultant-Spatial Analysis, Inc.
WHY EHS FACILITY SITE MAPS?
National Fire Protection Association (NFPA) Fire Health Instability Specified
WHAT WAS TO BE MAPPED? (WITHIN.25 MILE RADIUS OF FACILITY) This is a lot of information. on top of an existing basemap with a lot of info
MAPPING CHALLENGES Over 50 facilities, vastly different geographies Pope House = 0.0003 Sq. Mi. (8352.05 Sq. Feet) Pope House
MAPPING CHALLENGES Lake Johnson = 0.708747 Sq. Mi. (19,758,600 Sq. Ft.) EHS Buildings=
MAPPING CHALLENGES Data Huge amount of information Must lay over an existing basemap symbology Some data exist Some data exist & some data doesn t exist Some basemap data is too outdated for EHS Site Mapping Some utility data exist but is unavailable
SPECIAL MAPPING CHALLENGES Project & Product are completely new to city No existing map for reference No existing EHS data specifications No graphic specifications Data Organization Colors Size Attributes Labels Symbols
WHY DATA DRIVEN PAGES? Dynamic Elements = o o o o Reduced the number of MXDs Limit symbols in legends to just those in current map extent. Automatic Locator Update Map Collar text was better controlled/changed through dynamic text. o Scale o Rotation o Coordinates o Address o Sub-titles o Issue date
MAPPING CHALLENGES SOLVED- GEOGRAPHY Over 50 facilities, vastly different geographies Each DDP Map has custom scale/rotation Benefits: Able to choose the best scale for each situation Large scale map (24 x 36) Benefits: Allowed a closer inspection of EHS features. Entire park on single map Still functional, can be rolled up & carried easily
MAPPING CHALLENGES SOLVED-DATA Huge amount of information 7 legends to organize data by subject Employed DDP option to only show the relevant features within extent Simplified Legend
MAPPING CHALLENGES SOLVED-DATA Huge amount of information- Cont. Conventional symbology to assist in more intuitive feature identification.
MAPPING CHALLENGES SOLVED-DATA Must lay over an existing basemap symbology No issue-current CoR basemap is very nice and sits well under other features.
MAPPING CHALLENGES SOLVED-DATA Some data exist & some data doesn t exist Used various data analysis techniques to derive features from other source layers. Example for customized Points of Interest Parcels > APA Activity Codes > POI pts POI > POI pts EMS/Fire/Law Enforcement layers > POI pts Raleigh Basemap Recreation polys > POI pts Editing/creating/updating features
MAPPING CHALLENGES SOLVED-DATA Some basemap data is too outdated for EHS Mapping use Digitize.digitize updated the parks that needed it using current available imagery
MAPPING CHALLENGES SOLVED-DATA Some utility data exist but is unavailable Had to omit gas lines for the initial issue of map series. Email dated: 1/27/2014 SCANA (our parent company) does not allow for the release of electronic data regarding our infrastructure. The only information that is made available to the public can be found on the National Pipeline Mapping System https://www.npms.phmsa.dot.gov/. The NPMS includes PSNC s transmission data and does not include distribution data.
FINAL PRODUCT = 6 MXDS INSTEAD OF 50 Standard Map
FINAL PRODUCT = 6 MXDS INSTEAD OF 50 Example Inset Map
METADATA FGDC Compliant Metadata for EHS features and Fire Truck Routes.
LESSONS LEARNED Bigger is better in most cases. Reason: Density of features. Anything smaller than poster size will lack functionality. If Gas lines, stormwater BMPs, wetlands or other data are needed, create it (survey, digitize from as-builts, etc.) Reason: Not available in GIS formats. Required features Quick completion of project is best. Reason: Basemap is constantly changing. Parks & Rec facilities construct, renovate and move features FREQUENTLY.
