This page is designed to help GIS and IT personnel identify technologies during proposal and contract development, procurement, and acquisition of new systems to ensure that they are compatible with existing GIS systems within the County. This document supports the Chief Information Office’s mission of reducing redundant development platforms and streamlining the development, storage, maintenance, and access to geographic data and GIS application development.

At its heart is the following table which lists the various tiers of a GIS system, and our preferred technologies. While the County does not enforce these technologies as standards, it is noted that GIS systems not using these technologies will receive increased scrutiny by the Chief Information Office and the Geographic Information Officer.
