- 3. Geographic Information System GIS = A Geographic Information System (GIS) is any system that captures, stores, analyzes, manages, and presents data that are linked to location(s). GIS is the merging of cartography, statistical analysis, and database technology.
- 5. Typical GIS work flow Roles Cartographer Scientific Aides Data Base Managers Data Base Analysts Biologists Environmental Scientists Research Analysts (GIS) Collection Management Analysis Reporting X X X X X X X X X X X X X X X
- 6. Spatial Analysis Attribute Queries – population, temperature, WHR Asking Questions: ? ? ? "Everything is related to everything else, but near things are more related than distant things." Waldo Tobler Modeling - suitability, predictive Regression – dependent/independent variables Interpolation – statistical surfaces, kriging, DEM Auto-Correlation – hot-spots, density, clustering Proximity Analysis – buffers, connectivity, topology
- 7. Are these Swainson’s hawk nests clustered? Yes! But why?
- 8. Which streams are more likely to get NZMS? What’s the least demanding path up this hill? Where is the center of this recent poaching activity? ? ? ? ? ? ? ? Which Habitat blocks are critical for connectivity?
- 9. Species Habitat Suitability Interpolated Surface Insolation, interpolated from NASA Climate data. GosHawk habitat suitability, derived from vegetation data and known GosHawk occurrences Models: help answer questions
- 10. GIS Automation Why Automate GIS workflows? Standardized Reports and Figures Custom tools can be built to accommodate numerous programs. Provides repeatability Supports non-GIS users Saves time – fast answers and less staff time
- 11. ArcGIS “Model” 1) Re-useable 2) Adaptable 3) Easy to Modify (no code) 4) Batch processing
- 12. Reporting Applications User Forms to match Field Data sheets Front ends to GDBs and Databases Fast reports Minimal GIS skills needed to create report
- 13. Automated Reports/Maps Final Report consists of a series of maps and summarized tables
- 14. Custom GPS Maps Spotted Owl Data on Garmin 76c Depth surface model used at Caples Lake 2008: Surface and grid were available on Garmin 60cs
- 15. North Central Region GIS crew in the field, Caples lake 2008 …and that’s what GIS is.
