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

Data vs. Viewers 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 Viewer • Ready to use • Web-based • Limited number of layers • Limited analysis • May not be able to add your data* • * Arc. GIS online, Google Earth

GIS data

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

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