Delaware County Office of Data and Mapping Innovation (ODMI), using a Geographic Information System, supports departments within the County with custom mapping, interactive applications, and authoritative data to be used in their workflows and engagement with the public. The office always supports and works with local governments, private companies, and the public.

What is a Geographic Information System?
A geographic information system (GIS) is a platform, that creates, manages, analyzes, and maps all types of data. GIS connects data to a map, integrating location data (where things are) with all types of descriptive information (what things are like there). This provides a foundation for mapping and analysis that is used in science and almost every industry. GIS helps users understand patterns, relationships, and geographic context. The benefits include improved communication and efficiency as well as better management and decision making. (ESRI)
