  "textContent": "The Hub, Edinburgh rendered with Beakerboy’s OSM Building Viewer https://beakerboy.github.io/OSMBuilding/index.html?id=42997989\n\nI’m working on a project using OSM building data so I thought I’d familiarise myself with the building:part and roof tags and see what the editing process is like.\n\nThe Hub only had height data and a basic outline tagged for the spire, so as the highest man made point in Edinburgh, it made for a good candidate to get stuck in.\n\nI used height data from the OGL licensed Scottish LiDAR Phase 5 DSM that covers Edinburgh, and photos of the building from Wikimedia Commons\n\nThe elevation profile tool in QGIS proved useful for exploring the LiDAR data (after I worked out how to right-click to confirm the path). I normalised the elevation to zero with the raster calculator and set a custom colour ramp to aid visualisation:\n\nDefinitely fiddly to get right but interesting to see the level of 3D detail achievable with just a handful of tags and open data. There are more details to sort out, but I think I made a decent start.\n\nVisualised changeset: https://resultmaps.neis-one.org/osm-change-viz?c=180674112#20/55.94878/-3.19521\n\nHere’s what it looked like in Streets GL and F4Map before my edits (these take a while to update)\n\nhttps://streets-gl.pages.dev/#55.94901,-3.19519,45.00,302.70,342.25\n\nhttps://demo.f4map.com/#lat=55.9489462&lon=-3.1951278&zoom=19&camera.phi=56.15\n\n(I tagged the main pitched roof seen here yesterday)",
