Seamless backfill

[dhardestylewis]

Here's the link for USGS's 1 arc second (30m). Other USGS seamless DEMs are similarly located. https://s3.console.aws.amazon.com/s3/buckets/prd-tnm?prefix=StagedProducts/Elevation/1/TIFF/&region=us-west-2

We will want to backfill using all available USGS seamless DEMs

[dhardestylewis]

The following USGS seamless data will be used as backfill to the best-in-time-and-space algo

We anticipate this will mainly impact areas

• outside of Texas border and
• maybe a handful of tiles along the coast

• [ ] ⏸️ in order to rapidly facilitate TNRIS & CWE requests for 1m resampling accuracy results in specific inner Texas areas, inclusion of seamless backfill paused

👉 check table best-in-time-and-space merged with table actual TNRIS Lidar DEM tiles to see if any inner Texas areas actually suffer any gaps in coverage: https://github.com/dhardestylewis/terrain_aggregator/issues/41
