Technicians, analysts, programmers and database administrators work in departments throughout the city to manage hundreds of data sets, produce maps and posters, conduct analyses that support operations and planning, and provide the public with access to powerful mapping tools. Products and services include:
Denver's Open Data Catalog went live in July of 2012 to provide easy access to the City's geospatial data and to promote government transparency. Now, citizens anywhere can download over two hundred data layers in spatial and non-spatial data formats. Data formats include Shapefile, Esri File Geodatabase, AutoCAD DWG, Comma-Separated Values (CSV), Keyhole Markup Language (KML), and Metadata in XML format. These data are viewable in a variety of software, including Esri ArcGIS, Google Earth, Google Maps, and Microsoft Excel. You are free to copy, distribute, transmit and adapt the data in this catalog under an open license, the Creative Commons Attribution 3.0 license (CC BY 3.0). Please visit the Open Data Catalog for more information.
Denver Maps are a collection of customized public facing maps that provide information commonly requested by citizens, businesses, or others. They are designed to answer your questions quickly and easily for any given location within the City and County of Denver. Maps inform Zoning, Property Records, Parks and Recreation opportunities, Neighborhoods, Crime, and more. These maps are embedded throughout the City's website for ease of discovery and use. Please visit the main Denver Maps page to begin using the map applications.
The City and County of Denver has an extensive collection of aerial imagery for use in its Geographic Information Systems. The City obtained its first high-resolution aerials in the year 2000 and has collected them every two years since. In 2006, the Denver Regional Council of Governments (DRCOG) initiated a regional collection effort, known as the Denver Regional Aerial Photography Project, or the DRAPP. The DRAPP allows for various municipalities, as well as other government and quasi-government agencies, to contribute to the cost of a regional aerial imagery acquisition, allowing for a higher quality product at a lower cost.
Denver's Open Data Catalog contains the following imagery: Black and white tiles for 1933, 1995, and 2000, and color imagery for 2004, 2006, and 2008. DRAPP imagery was collected in 2010, 2012, and 2014. However, with a 3" inch resolution, the size of the files have proven a challenge to serve via the ODC. 2014 and past DRAPP imagery are available for purchase from MapMart, Inc. For more information on the DRAPP, please visit the DRCOG website. http://www.drcog.org/
Access to the Wastewater Storm and Sanitary Infrastructure plat map PDF files are currently being updated to a new Denver Maps platform.
The following process will allow you to retrieve documents at your convenience.
The Plat maps can be temporarily obtained through self-service by building the plat map URL for a specific document:
For Sanitary Plat Maps, append the wastewater plat map grid number in this format: SanPlatMap_RangeNumber_TownshipNumber_SectionNumberQuarterSectionNumber.pdf
(ex. SanPlatMap_66_02_3601.pdf) to the end of this URL: https://www.denvergov.org/denvermaps/documents/wmd/platmaps/
For Storm Plat Maps, append the wastewater plat map grid number in this format: StmPlatMap_RangeNumber_TownshipNumber_SectionNumberQuarterSectionNumber.pdf
(ex. StmPlatMap_66_02_3601.pdf) to the end of this URL: https://www.denvergov.org/denvermaps/documents/wmd/platmaps/
To determine the wastewater plat map grid number, use the Wastewater Sanitary and Storm Sewer Reference Map.
Note*: Before accessing the plat maps we recommend clearing your browser cache.
