Adding the spatial element to GIS expands your ability to view changes over time. With spatial data, a government can more readily measure and visually present cause and effect. Agencies can apply it to track myriad conditions, such as city boundary movements, housing stock changes, forest areas, flood effects or whether roads have been plowed of snow. GIS allows modeling. You can pose what-if questions for concerns such as economic development, water levels, urban sprawl and livestock or factory sitings.
Successive models can produce simulations that show the effect of various factors on an area.
You can open a new channel for public access by implementing GIS applications on the Internet that include interactive visualizations. GIS can foster collaboration, communication and insight about conditions affecting government workers, citizens and local businesses. States must realize that their data is far more useful when leavened with digital map segments and satellite imagery in other words, the lay of the land. The more granular the scale, the more viable GIS becomes. Agencies can use Global Positioning System devices and digital image capture to align data and information to a location.
