BIS Completes GIS Data Cleansing

topology

Databases are ultimately only as useful as the information they contain and the same is true of the GIS, or Geographical Information System, that BIS operates.  GIS is used to capture, store and retrieve mapping information and can be used to show many different kinds of data for clients. However, when errors creep into the collected data this can distort reports including maps generated from the information. Two examples include how mapping polygons interact with one another: they should not overlap nor leave a gaps between the shapes, as this can cause land to either be double counted or overlooked. To this end the BIS GIS team recently completed a topology data cleansing service, which is to apply topology fixes to the information in our databases.

The result? We removed over fifty thousand errors from thirty three counties in our databases. The main benefit of this process was to remove errors from reports and database queries but it also improved the aesthetics of generated maps and makes editing the information a smoother, cleaner and quicker process. At BIS Consulting we take pride in our work and we want you, as our client, to be confident when you are using your map or sharing it with others.
