Map and Data Services

Public Access to CAGIS Data

In addition to CAGIS Online, a powerful public map explorer for Hamilton County, CAGIS provides public access to GIS layers and a variety of data and mapping services. Some of these services are provided free of charge, while others incur fees based on the staff time involved. CAGIS data primarily covers only Hamilton County, although the system does have some data for contiguous counties. For more specifics about CAGIS data layers and maps, please refer to the FAQ page.

Free GIS Layers Available to Download

CAGIS offers a set of standard GIS layers available for download, free of charge. These layers are updated quarterly. While these layers are free to the public, CAGIS does not provide any technical assistance on how to download, convert or use the data in any systems. Refer to the CAGIS GIS Download Page for a complete list of layers available.

Custom Mapping and Data Services

In addition to the free GIS data layers, CAGIS provides a number of data and product-related services to individuals or companies. Customers can request these services via email, phone or walk-in. The fee associated with these services is based on a standard staff hourly rate of $100. The minimum charge is 15 minutes of staff time ($25) and then increases by increments of 15 minutes. A request that is likely to exceed 2 hours of staff time needs prior approval from CAGIS management. The data and product services include:

  • Order up-to-date GIS layers set (Approved Layer List in Shape File Format) on DVD or as email attachments (if practicable and not exceeding size limit)
  • Extract data by CAGIS map facets from GIS repository to various supported formats (Shape file, File GDB, DXF, DWG)
  • Create pre-determined template based CAGIS planimetric, topographic and property maps
  • Create customized maps of various paper size, scale, and layers
  • Perform GIS analysis and generate reports

In any case, a maximum of one plot copy will be provided per request. The customer will be provided a digital PDF document of the plotted map via email only on request at time of service.
