Project still alive? #219

Open Mis012 opened 2 months ago

Mis012 commented 2 months ago

The readme says that additional sources should be suggested, however recent suggestions have no responses, and the repo has last been updated 7 years ago. At the very least https://github.com/tilezen/joerd/blob/master/docs/attribution.md would presumably have to be newer if there was any source added in the last 7 years. Does this mean this project is dead? Multiple sources still link to this repo as if it was not, but it certainly doesn't feel alive.

The project is still alive – the data is still available on the AWS Open Data registry – but we haven't found funding to update the tiles with all the suggested updates. Even if AWS foots the bill on the S3 bucket, It takes a significant amount of money to run the servers that generate the tiles, let alone the engineering time required to pull together the updated data.

To add color to what @iandees mentioned, this repo continues to track raster elevation data sources and has been used to build several versions of a global dataset starting at Mapzen, using both the code in this repo (version 1 no longer public), the code in marblecutter (v2 public on AWS), and custom GDAL + Mapserver based stack (v3 to solve the edge effect bugs noted here several times at Snap but sadly not public).

We're still interested in a v4 build but in maintenance and source collection mode until funding materializes. If you have funding please get in touch!
