Colorado’s Data Repository

Explore COlorado open data on the Colorado Information Marketplace

Go Code Colorado competition participants can explore Colorado public data through the Colorado Information Marketplace (CIM) public data portal and learn tips and tricks for using CIM.

The Colorado Information Marketplace is an effort by the Colorado Governor’s Office of Information Technology to provide Colorado public data to citizens. It offers a dataset catalog and dataset repository, an application programming interface (API) and several tools for exploring and visualizing data.

The Go Code Colorado data team collects, reviews and reformats (if necessary) data to make it easier to work with before uploading it to CIM.

Be sure to check out the new Colorado Data Portal Status Blog for dataset status notifications, interesting insights from data providers and responses to questions asked via the feedback form on CIM.

The Go Code Colorado data team has collected and formatted Colorado public data specifically for Go Code Colorado. You can also search for keyword “gocode” on CIM.

Please check out the list of other data resources participants can use for the Go Code Colorado competition. And, if you’re new to the Go Code Competition, be sure to visit the Compete and Rules  sections of our website to learn more about the competition.

Tips and Tricks for Using CIM

One great feature of CIM is its ability to create filtered views on tables, save them and make them publicly available to others. When a user is looking for a known dataset, seeing data interpretations that have been completed by others can be greatly beneficial.

Look at Business Entities as an example:


Colorado open data is available for browsing through the Colorado Information Marketplace. There is lots of data available on CIM for Go Code Colorado participants to use.


There is a detriment to the filtered views feature, however, and it comes into play for users who don’t know which dataset they’re looking for. In this scenario, simply browsing the catalog can seem a bit overwhelming, because users are looking for ONLY the raw data in an effort to see which unique datasets are available to them. A simple solution is to view just “Datasets” or “Maps”. Here’s how to do it:


Browse for Colorado open data more easily by filtering your search results with View Type filters.


The distinction between “Maps” and “Datasets” continues to be important as you move through the options on the CIM data portal, and particularly when you use the SODA API feature. As amazing as it sounds, every dataset and map that you find can be pinged with an API call to power your application with a data feed from the agency.

In the tutorial below, Chris Metcalf (our developer friend at Socrata) provides some basic context about how to use CIM (powered by Socrata).



In next tutorial below, you can learn greater detail about the use of the Geospatial API, which allows API access to the “Maps” datasets, specifically. For a full list of all API documentation, check out Socrata’s Geospatial Datasets and APIs
