<div dir="ltr"><div>Hi Travis:</div><div><br></div><div>1./ correct, OGC API - Coverages does not support HTTP Range request headers at the moment. This</div><div>concept was presented and discussed at last week's Cloud Native Geospatial Outreach Event. As OGC API -</div><div>Coverages evolves, we may see a conformance class for cloud optimized coverage requests. Having said this,</div><div>I see a use case where we could provide this capability where if an HTTP</div><div>Range request is passed to /collections/{collectionId}/coverage, this would override any OGC API - Coverages</div><div>functionality, thus kicking into "cloud optimized" mode. Please feel free to open a pygeoapi issue on GitHub</div><div>and I can take a deeper look.<br></div><div><br></div><div>Regarding using GDAL's OGC API - Coverages support, can you retry with the following changed in your</div><div>pygeoapi provider configuration:</div><div><br></div><div>format:</div><div> name: GTiff # per <a href="https://docs.pygeoapi.io/en/latest/data-publishing/ogcapi-coverages.html#rasterio" target="_blank">https://docs.pygeoapi.io/en/latest/data-publishing/ogcapi-coverages.html#rasterio</a></div><div> mimetype: image/tiff; application=geotiff</div><div><br></div><div>This then works for me when running gdalinfo OGCAPI:<a href="http://example.org/collections/foogdps-temperature" target="_blank">http://example.org/collections/foogdps-temperature</a> -oo API=COVERAGE</div><div><br></div><div><br></div><div>2./ Regarding using AWS vars, I believe this is natively supported in Rasterio proper via environment variables.</div><div><br></div><div>..Tom</div><div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Apr 23, 2022 at 10:29 AM Travis Kirstine <<a href="mailto:traviskirstine@gmail.com" target="_blank">traviskirstine@gmail.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>Hi All,</div><div><br></div><div>Sorry but I'm a bit of newb to the Open API / OGC API world and have a few questions that perhaps some kind person could shed some light on.</div><div><br></div><div>I have a client who would like to leverage a swagger / open api interface to retrieve aerial imagery data in a Cloud Optimized Geotiff format using http range requests.
