Hi CT GIS Community:
This is Carl Zimmerman (GIS Coordinator) from the CT GIS Office, and I wanted to give you a quick update on the 2023 imagery acquisition that many of you are wondering about. After some technical and quality delays around the many buy-ups of this complicated and high-resolution data capture (e.g., Imagery, LiDAR, elevation, and GIS products (such as 3d buildings)), we have a firm schedule.
Imagery will be delivered in four blocks this Spring, and the Lidar and GIS products will follow approximately two months behind the imagery in a similar pattern. Expect to see some draft imagery from CT ECO starting in early Spring and more added over the following few months. Lidar, elevation, and GIS Products will come late in the Spring and early Summer.
For us to have the best quality for this very large data set(s), four critical steps need to be finished: 1) the imagery data will be QA/QC’d by an internal subcontractor for the Vendor; 2) the GIS Office and GIS Community will review it; 3) the identified errors will be corrected by the Vendor; and 4) the finished data will be put into web services or downloadable format for you to consume. Please be patient as we get moving on this large and detailed project. More updates to follow on our progress.
Finally, I will be reaching out to some of you in December and the early Winter for your assistance in reviewing the data. If interested in helping with this large project let Alfredo Herrera or myself know.

CT ECO has received a number of upgrades this summer and there are a couple more in the pipeline. CT ECO is a system of five servers including a web server, three mapping servers, a database server, and a large storage drive. They connect to each other so that loads of Connecticut’s geographic data can make it’s way to you on both CT ECO and the CT Geodata Portal. Along with some security patches and other minor things, the major upgrades so far are –
- operating systems upgraded on all of the servers which are now running the latest Windows Server 2022,
- software upgraded bringing the mapping servers to ArcGIS Server version 10.9.1,
- with the software upgrades, we republished all services under the ArcPro runtime (previously ArcMap runtime), and
- increased the number of processing cores in order to increase the drawing speed and reliability of services.
We are also working on upgrading the large storage drive to increase access speed and provide more room for all the 2023 files and tiles that we will be here before we know it. The team, including UConn IT attempted, this twice (gulp) with issues that we are working through before attempting again on on Tuesday, Sept 5 at 5pm.
And also coming soon will be another software upgrade to ArcGIS Server version 11.1, the latest and greatest.
All of these upgrades have resulted in periodic system downtime and interruptions in service. A number of UConn IT folks work closely with the CT ECO mapping folks to bring the worlds together and minimize impact for our users. We greatly appreciate your patience while we navigate running and maintaining a complicated system. As always, feel free to email us at email@example.com with any issues or questions.

The Geodata Portal will provide access to high-quality geospatial data for Connecticut data practitioners across all sectors and industries. By hosting, aggregating, and sharing trusted and reliable geospatial data, users can expect to easily find trusted data to meet their needs. The Geodata Portal is available at geodata.ct.gov and will build on the success of and be integrated with the state’s open data portal. The Geodata Portal contains, maps, apps, and services from multiple authoritative data sources including the CT Dept. of Transportation (DOT), CT Dept. of Energy and Environmental Protection (DEEP), and CT ECO.
The Connecticut Broadband Availability Map was created to help citizens and policymakers understand the strengths and weaknesses of broadband infrastructure in the state. Continue reading
