GIS (also known as mapping)

What is GIS?

GIS is an acronym for Geographic Information Systems.

Delta county uses GIS to manage spatial information, essentially modern day mapping.  A GIS system brings power to mapping and provides visual representations of problems and can analyze and interpret data to find patterns and trends.  You may not know it, but you probably use a GIS application on a regular basis, for example Google maps, Zillow, Petfinder, Craiglist, Pokémon GO, and many many more.  In its simplest form, GIS is information attached to a location stored in a computer file with the address and GPS location that can be shown on a map.  Below are some GIS maps specifically for Delta County (select the image to link to the appropriate map/page).

The winners of the GIS Day Atlas drawing on November 15, 2017 are as follows:
1st pick:  Jessie Houghton
2nd pick: Albert Martinez


Interactive Delta County Colorado Property Information Map B
This mapping application works with all web browsers and will be the main Interactive map later this year as Map B below is outdated.  This map has layers of county parcels (owner name and link to assessor records), roads, commissioner districts, flood zones, voter precinct areas, town boundaries, city zoning, water companies, address points, and 2016 aerial imagery.  

It’s a robust application with widgets that change the base layer, search, draw, measure, email, and print. Please note that it is undergoing some changes to increase usability over this year.

Old Interactive Delta County Map A

**IMPORTANT** THIS MAP ONLY WORKS WITH THE INTERNET EXPLORER WEB BROWSER. This is due to the Silverlight technology depreciation.  This map will expire at the end of 2017 and will no longer be available for use.
