  1. What is GIS? And what is it good for?

  2. What is GIS? Geographic Information Science is the discipline of storing, managing and analyzing data that have a spatial component, and A Geographic Information System (GIS) is the collective name for the hardware, software, and data used to capture, manage, analyze, and display spatially referenced information

  3. What can you do with GIS? • Store and query spatially referenced data • Spatially analyze complex data sets • Interpret and distribute results through maps

  4. Store spatial data Geography matters in every business and every discipline, and almost all information has geographic (spatial) aspects GIS allows information that was once limited to spreadsheets and databases to be used in a more powerful way by analyzing complex spatial relationships fast and efficiently GIS is rapidly being adopted as a standard management tool in government and industry

  5. What can you do with GIS? • Store and query spatially referenced data • Spatially analyze complex data sets • Interpret and distribute results through maps

  6. Spatial analysis Spatial analysis or spatial statistics is the study of relationships among entities using their topological, geometric, or geographic properties Until GIS, the calculations to determine these relationships were onerous and often infeasible

  7. Spatial analysis GIS allows you to query data on the basis of attributes and/or spatial relationship • ex., nearby, adjacent, inside vs. outside • connected or disjoint • spatially correlated • elevations, slope, area, aspect • hydrology, flow directions

  8. What can you do with GIS? • Store and query spatially referenced data • Spatially analyze complex data sets • Interpret and distribute results through maps

  9. Cartography Maps are an extremely effective means of communicating ideas and conveying information in a compact, efficient manner GIS software provides complete control over production of publication-quality maps in print or electronic form Web-based publishing : on-line querying and map customization

  10. Access to GIS DWR has an Enterprise License Agreement for ESRI ArcGIS software that provides an unlimited number of seats, including most specialized tools and extensions Training is available internally and through license agreement

  11. Access to GIS COSTS • No software costs • No cost for introductory training • DWR Training Center • two-day class with staff subject matter experts • Opportunities for no-cost additional training • Training Credits included in license agreement used to periodically hold classes in advanced topics
