There are countless of open source products we use and love at DHI GRAS, and it is very dear to us to give back to the community.

Therefore, we are thrilled to announce that we have just released our new, light-weight tile server Terracotta as free software under an MIT License!

Terracotta directly serves your (cloud-optimized) GeoTIFF files, so you don't need to apply any pre-processing to get your raster data online, and it supports serverless deployment on AWS Lambda, so you can serve your data without any permanent infrastructure.

We urge you to check it out, and look forward to your feedback.
