Transcript

  • 1. An introduction to data sources and possible projects. Marc Albrecht University of Nebraska at Kearney Department of Biology GIS Resources and Projects
  • 2. GIS Projects: An Overview
    • Large companies and institutions are undertaking huge, complex GIS projects all the time. You have run across some examples. The purpose here is to show you some of data sources available to you, and some project ideas that might be feasible in the classroom.
  • 3. To Start a Project you need:
    • GIS software:
      • ArcExplorer or other free GIS viewer
    • Basemaps:
      • Examples coming up!
    • Your data:
      • If you have some, and can input it – that’s great!
    • Training:
      • If you can find attend a class - or do it online, it helps!
  • 4. Data Sources
    • Some base maps that are available (many for free! ).
      • 1. Topographic maps for Nebraska have been digitized by the Nebraska Conservation and Survey Division Service
      • Other maps are available from state agencies or through the USGS map download area
  • 5. 2. Aerial Photos
    • National Aerial Photography Program (NAPP)
      • Cycle 1 ended 1991
      • Cycle 2 started in 1999.
      • Resolution is about 2 meters!
      • One file like this is about 25 Mb in size
      • But also available as JPEGs at about 2.5 Mb each
      • note: the next slide may take a moment to load!
    • Publicly available through the USGS site and, for Nebraska, through the Department of Natural Resources ( DNR )
  • 6. 4. Other Base Maps
    • The Nebraska Department of Natural Resources has many base maps to download!
      • Soil type (2 acre resolution), Land use (8 acre resolution)
      • Erosion maps, Section lines/points, contours (30 m res)
      • NRD, hydrologic, and political boundaries and more!
      • How to get there? Go to their site - select ‘Subjects A-Z’, then ‘D’ (for Data Bank), then ‘Spatial/GIS databases’
        • Look for ‘GIS databases request site’
        • You just request a map type and location and give your email, they email you a ftp address when the job is processed!
  • 7. Part IV: Ongoing Projects and other Software
    • USGS GAP Analysis
      • 33 States and 200 agencies involved
      • Digital mapping of vegetation and vertebrate animal distributions in the USA
      • invertebrates too maybe!
    A Geographic Approach to Planning for Biological Diversity
  • 8. What Other Software is out there?
    • EPA “BASINS” (this is a hyperlink)
      • 500 Mb database per state
      • Free
      • hooks into ArcView (required)
      • 3.0 is current and very useful version
      • useful for researchers to citizens groups!
  • 9. Part V: Example Projects
    • Project Steps
      • 1. Specify Goals
      • 2. Obtain best base maps possible
      • 3. Acquire remote sensing imagery (e.g. aerial photos)
      • 4. Add your data
      • 5. Analyze the data, manipulate the themes, add to or change the data.
  • 10. Site Characterization
    • A. If a site needs to be ‘shown off’, GIS is a great way to do it.
    • B. Aerial photos and line overlays are an effective way of familiarizing people with an area (e.g. part of Buffalo County, NE to the right)
  • 11. Example: Fort Robinson, NE
    • Fort Robinson, NE is a historical site with over 100 years of active service. We are:
      • Trail mapping
      • Verifying boundaries
      • Possible future projects include
        • Vegetation mapping
        • Game animal management
        • Range quality use and management planning
  • 12. Aerial photo with roads and points (copy and zoom in on this image – lots of detail!)
  • 13. Contours Overlaying Aerial Photo
  • 14. Possible GIS Projects
    • 1. Endangered Species Conservation
      • A. field research and literature search to quantify the environmental requirements of a species
      • B. Use GIS database to identify areas that fulfill all requirements (layers, queries, buffers) for the species
      • C. Overlay known distributions of the species to identify areas under threat and to locate any uninhabited but candidate locations possible introduction of new populations

Images in this presentation are from the ESRI website , the Nebraska DNR , the Environmental Protection Agency , and the U.S. Geological Service . Please visit their sites to learn more! Thanks. 11/99. The End!
