GIS Data

The  Information Technology Department (ITD) through its GIS Division, maintains a central repository of production geographic data available to all Miami-Dade County departments. This data is comprised of numerous layers; the street network and property (parcel) layers being the primary base layers. Maintenance of the layers is performed by the responsible department(s) or by ITD.  Information concerning geographic data or metadata as it is referred, is available for most layers.

Geographic data is stored in ArcSDE in a geodatabase file structure. The data is also replicated to Shapefile format.

Most production data, except parcel data, can be downloaded for free from the GIS Self Services website. Parcel data is available for a fee by request or through a subscription service Adobe Reader which provides automatic weekly updates.
