Maintenance Alert

Thank you for your patience as we improve our online services.

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.

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.

For assistance contact us via email at gis@miamidade.gov.

GIS Metadata

Metadata is essentially “data about data”. It provides vital information such as the how, what, when, where, why, etc. of data to users and future data maintainers. It states the data limitations, scales, reference, contact, currentness, attributes, process and more of how the data was created. It is meant to protect against incorrect and inaccurate data use during mapping and analysis processes that could be costly to an organization.
 
Miami-Dade County (MDC) metadata follows the Federal Geographic Data Committee, Content Standard for Digital Geospatial Metadata (FGDC CSDGM) standards, one among several other metadata styles and profiles supported in FGDC and ESRI's Geographic Information System (GIS) software. However, MDC plans to migrate to the newly adopted International Organization for Standardization (ISO).

The GIS Central Data Repository (GCDR) also referred to as “Production” consists of hundreds of GIS layers, and metadata enforced by the County’s Geographic Information System (GIS) Data and Metadata Administrator, during the addition or update of production layers. This is to facilitate a goal of achieving 100% metadata documentation for all its production layers. Metadata for Public layers that contains metadata can be accessed via the County's GIS Self Services site.

With that said, MDC developed basic GIS Metadata standards and procedures to aid our GIS users with the collection, creation and maintenance of metadata. In addition, GIS metadata training and assistance are provided via class or one-on-one as needed. To aid users with the reengineering of ArcGIS metadata style, MDC applied and was awarded a 2012 FGDC grant, FGDC Metadata Trainer and Outreach Assistance. This grant allows us to extend training and outreach assistance beyond MDC employees to include cities, regional areas and GIS partners, and to share materials developed through the grant.

Material and Information

  • Metadata Form – collection of information prior to metadata creation, especially helpful if the layer creator differs from the metadata creator.
  • Metadata Standards and Procedures – provides the basic ArcGIS metadata configurations, metadata field explanations and workflow
  • Metadata training workshop - Training Workshops are scheduled from January to March 2015.
  • Metadata for Managers – provides a high level overview of the importance of metadata
