CT ECO Download Tool Update
The CT ECO Imagery and Elevation Download Tool now includes a highly requested batch download option! The batch download enables users to select and download multiple tiles at once without having to click on each one individually. Batch download works with different formats of 2012, 2016, 2019, or 2023 aerial imagery or elevation from 2016 or 2023 (2026 aerial and elevation coming soon). The tool returns a single zip file of multiple zipped tiles.
For instructions and tips visit the Help Window within the Download tool. Look for Batch Download on the left and then notice Run Batch Download Tool, Unizp, and Download Limiations across the top.
A couple of things to note that aren’t ideal but are not optional at this time.
- Although any map layer can be selected as input, the tool requires the "Tile Grid" layer (the first option) or it returns an “invalid input layer” error. Hopefully future releases allow us to control the input layer.
- The tool uses selected tiles which are shown with black hashed lines on the map. To make a NEW selection, users must first clear the current selection using the trash icon. A bit wonky.
- For each new selection, the "Tile Grid" layer must be re-added as the input for the tool, otherwise it will download the tiles selected in the prior session.
- The tool limits the number of tiles that can be downloaded at one time due to the single download file size. The limits are listed in the Help > Batch Download > Download Limitations section.
As always, if you find any issues or have questions, email us at clear@uconn.edu.
Many thanks to Qian (Rachel) on the team for adding the Batch Download function to the tool.
