We help governments who run on address data

Governments run on address data, but many jurisdictions have gaps they don’t know exist. Through ACE, DATAMARK Technologies has helped agencies uncover more than 2 million address candidates, with clients identifying an average of 51,000 candidates per county. ACE helps agencies find and resolve missing, incomplete, and inconsistent address data to create a more accurate and trusted Master Address Point Dataset.

“We pursued DATAMARK’s ACE solution and we are very glad that we did. DATAMARK’s expert staff gave us updates and advice throughout the whole process… We were able to find about 150 addresses and 300 sub- addresses that were not present in the GIS, and we created a much closer working relationship with the various addressing coordinators throughout the County. DATAMARK’s ACE was an essential tool to get our County GIS up to speed and was also one of the first crucial steps to prepare our GIS data for integration into the NG911 environment.”​
