<div dir="ltr"><div>I have loaded the OSM data and uploaded the rasters into the database. However I cannot find a way to query all data within a radius of a (long, lat) coordinate pair while seeding each returned part of the data with its corresponding elevation value from the rasters. Any query with ST_DWithin or similar does not return any rows even though the database is populated. It could be a projection issue. If you would be able to point me in the direction of any tutorials/walkthroughs of how to do this, I would appreciate it.<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Jun 20, 2021 at 9:45 PM James Keener <<a href="mailto:jim@jimkeener.com" target="_blank">jim@jimkeener.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Can you explain the issue you're having and what you've tried?

My use case of PostGIS is to store the United
States' OpenStreetMap (OSM) data. This is a solved problem
with a significant amount of documentation available.
However, my use case differs in that I want to add US DEM elevation
rasters to the database to enable my application to query and receive a
graph seeded with these elevation values depending on my users'
location. This problem has almost no good documentation,
and most solutions are outdated or fail on my test server. Other
services that provide elevation on demand are either too costly or do
not provide a small enough resolution for my use case. Thus, I hope that anyone can aid me in the setup and deployment
on this bespoke database.</div>
