Description
Hi- I have rasterized the Overture building data for the lower 48 twice, once with May 2026 data and once with August 2026 data. Both times there are strips of LA buildings missing from the source Overture vector data that also end up missing in the raster version. I have not investigated other areas, so this phenomena could be happening elsewhere. It is obvious when overlaid with any imagery so I'm unsure which of your sources is missing there. I also wanted to speak with you all about possibly sharing my rasterization code so that you might consider doing this rasterization with every release. I'm able to rasterize all of conus to 30m for building cover and building area in an afternoon on google cloud and mosaic it into two geotiffs. This is useful for wildland fire fuel applications. I am the LANDFIRE program lead for the Forest Service and we need building data for our maps and were hoping to use yours, if the missing buildings could be addressed.

Research direction
No repository file or test is named. Start by reproducing the reported gaps in the Overture building vector data for Los Angeles using the May and August 2026 datasets, overlaying the results with imagery, and tracing which source or processing step omits the strips. Done means identifying the missing-data cause and documenting a concrete correction or follow-up scope.
