调研方向

未指定任何仓库文件或测试。首先使用 2026 年 5 月和 8 月的数据集,重现 Los Angeles 的 Overture 建筑矢量数据中报告的缺失,将结果与影像叠加,并追踪是哪个来源或处理步骤遗漏了这些条带。完成的标准是确定缺失数据的原因,并记录具体的修正方案或后续工作的范围。

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.
