  1. GIS Data Sources:Where to find data to see where you are going Laura Ryckman TCEQ SWQM March 6, 2017

  2. Information Sources • Viewers • Datasets for use with programs • Where to get data?

  3. Data vs. Viewers Viewer Ready to use Web-based Limited number of layers Limited analysis May not be able to add your data* * ArcGIS online, Google Earth Data • File with spatial information • Multiple formats • May require processing • Projections • Scale • High flexibility for combining different data sets • Need a GIS program to map data

  4. Viewers

  5. TCEQ viewers https://www.tceq.texas.gov/gis/tceq-geographic-data-viewers

  6. Surface Water Quality Viewer • SWQM Segments • SWQM Assessment units • SWQM Stations • 2014 IR data http://tceq.maps.arcgis.com/apps/webappviewer/index.html?id=b0ab6bac411a49189106064b70bbe778t

  7. Surface Water Viewer • How to turn on the assessment units in the surface water viewer Check this box.

  8. TPWD GIS viewers • Texas Ecosystem Analytical Mapper (TEAM) • Interactive mapping tool to assist in understanding Texas habitats and to integrate vegetation data • Rare, Threatened, and Endangered Species • Listings of rare species or select a rare species by county • LWRCRP Statewide Inventory (2012) • Displays the lands owned or operated by governmental or non-profit entities which allow public access, for the conservation of historical, natural, recreational and wildlife resources. • Artificial Reefs • Fish Catch Rate by Minor Bay • Seagrass Viewer • Texas Watershed Viewer • Historical Imagery Viewer • A teaching tool for Earth Science, Texas History and Social Studies. http://tpwd.texas.gov/gis/

  9. TPWD Watershed Viewer • Click on the map to see the basin or watershed for a given point. • Uses existing watersheds; does not delineate to a point. https://tpwd.maps.arcgis.com/apps/Viewer/index.html?appid=2b3604bf9ced441a98c500763b8b1048

  10. TPWD – Rare, Threatened, Endanger Species Map Viewer

  11. USGS Species Viewer • Threatened and endangered species • Includes proposed species • No fish • Only amphibians, birds, mammals, and reptiles • May zoom to state and county https://gis1.usgs.gov/csas/gap/viewer/species/Map.aspx

  12. USGS – Hydrography Viewer https://viewer.nationalmap.gov/viewer/nhd.html?p=nhd

  13. Texas A&M Forest Service Information Portal http://texasforestinfo.tamu.edu/

  14. Texas A&M Forest Service Information Portal http://tfsfrd.tamu.edu/MapMyProperty/

  15. Model My Watershed https://wikiwatershed.org/ March 9th Webcast: https://www.epa.gov/watershedacademy/watershed-academy-webcast-seminars?utm_medium=email&utm_source=govdelivery

  16. ArcGIS Online – view downloaded data

  17. GIS data

  18. GRASS What programs can be used for GIS? Geographic Resource Analysis Support System SAGA Golden Software GEOSOFT System for Automated Geoscientific Analyses Software for Geochemistry for ArcGIS (geochemical analysis) and Target for ArcGIS (geological software) • Contains various programs for different needs (MapViewer 8 is used for spatial analysis) ESRI ESRI is the developer of ArcGIS products One of the most popular GIS programs Example: ArcMap, ArcGIS Online, ArcCatalog

  19. GIS data sources • Add Data from ArcMAP • Add Basemaps (satellite imagery, streets, topographic, oceans, etc.) • Add data from ArcGIS Online (search the online database)

  20. GIS Data Sources Click here! • USDA Geospatial Data Gateway • Contains a wide variety of data that can be downloaded • Census, climate, easements, government units, elevation, etc. • Texas Natural Resource Information System (TNRIS- part of TWDB) • Bathymetry, census boundaries, elevation, hydrology, land cover, soils, transportation • TCEQ • SWQM segs/AUs/stations, regional boundaries, wells, waste water outfalls, landfills, superfund sites, Edwards Aquifer boundaries and land cover, air monitoring sites • TPWD • Wildlife management areas, ecological mapping systems, geology, state parks • Texas watershed viewer, seagrass viewer, Golden-cheeked warbler habitat change

  21. Where can I get GIS data? • Water spatial data, groundwater, surface water, water quality (chemical, biological, physical characteristics), watershed theme maps • Streamflow gauging stations • Hydrography (National Hydrography Dataset and Watershed Boundary Dataset) • Hydrography Viewer – quick reference NHD, topographic imagery, transportation, land cover, elevation, natural hazards, streamflow gauges • Add data content, find coordinates, spot elevation, measure distances and areas, build queries, set buffers, annotate map https://water.usgs.gov/maps.html
