After trying this again on a bare EC2 instance I tried downloading a DEM to my laptop. Unzipping the file that got downloaded with the MacOS X expander created a...

It's active, but the Earth doesn't change all that much so we don't update it frequently. Some Australian data made it into the most recent build, but the data we...

It's not easy to get bulk data out of an Esri REST map service. I think that service uses the data mentioned on this ticket above that doesn't successfully unzip....

There is **a lot** of data here. I was going to start mirroring the 2m strips to the sources bucket, but there are well over 30k images, each in the...

Going with the 5m data. #### Listing files ``` lftp \ -c 'find' \ ftp://ftp.data.pgc.umn.edu/elev/dem/setsm/ArcticDEM/mosaic/v2.0/ \ | grep tar.gz > pgdc_5m_listing.txt ``` #### Mirroring files to openterrain S3 ``` cat...

Mirroring is in progress.

#### Transcoding files ``` aws s3 ls s3://elevation-sources-prod/pgdc_5m/ --recursive | \ grep tar.gz$ | awk '{print $4}' | \ while read filename; do bn=$(basename ${filename%.tar.gz}) make submit-job job=aws/transcode-job.json.hbs input=s3://elevation-sources-prod/${filename} output=s3://elevation-sources-transcoded/$(dirname...

When I tried adjusting GMTED to show a zoom earlier, nothing changed. I looked at the footprints database and noticed that GMTED has no footprint over Greenland:  The bit...

I transcoded GMTED from [here](https://edcintl.cr.usgs.gov/downloads/sciweb1/shared/topo/downloads/GMTED/Global_tiles_GMTED/300darcsec/mea/), but the resulting transcoded images don't mark zero as `nodata`, so we end up with stuff like this (with gmted blocking etopo):  And even...

When I loaded in some missing 30 arcsec GMTED to solve the problem mentioned in [the comment above](https://github.com/tilezen/joerd/issues/165#issuecomment-340808189), the DEM included water with a value of `0` (zero), so I...
