What is GIS
?
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.

Modeling - suitability, predictiveRegression – dependent/independent variablesInterpolation – statistical surfaces, kriging, DEMAuto-Correlation – hot-spots, density, clusteringProximity Analysis – buffers, connectivity, topology
Are these Swainson’s hawk nests clustered?
Yes! But why?
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?
Species Habitat Suitability Interpolated Surface
Insolation, interpolated from NASA Climate data.
GosHawk habitat suitability,derived from vegetation dataand known GosHawk occurrences
Models: help answer questions
GIS Automation
Why Automate GIS workflows?
Standardized Reports and Figures
Custom tools can be built to accommodatenumerous programs.
Provides repeatabilitySupports non-GIS users
Saves time – fast answers and less staff time
ArcGIS “Model”
1) Re-useable2) Adaptable3) Easy to Modify (no code)4) Batch processing
Reporting Applications
User Forms to matchField Data sheets
Front ends to GDBsand Databases Fast reports
