they often do not fit well with the human scale that we survey on the<br>
ground.<br></blockquote><div><br></div><div>In my area of the world, <a href="https://soilgrids.org/">https://soilgrids.org/</a> shows about 600ft, and the types pretty well match up with the ground around here. So, well within walking distance (for me, a mile radius ) scale. As data accumulates from repeated SAR passes, that will probably drop considerably in the next few years. URBAN-TEP ( <a href="https://urban-tep.eu/puma/tool/?id=574795484&lang=en">https://urban-tep.eu/puma/tool/?id=574795484&lang=en</a> )has global data ranging from 5 meters to tens of meters. And these are derived normalized data, the raw observational data is much better in some regions ( See their projects page ). The resolution is more determined by maintaining a global 90% bar than the underlying observations.<br></div><div>Not your backyard, but considerably better than what has been available:
"Worldwide inventory of human settlements (urban & rural) using one
global coverage of SAR data with 0.4 arcsec (~12 m) ground resolution
collected by the satellites TerraSAR-X / TanDEM-X in 2011-2013."</div><div><br>
