A greenfield site was never built on; a brownfield site was, and may hold slabs or pollution. What each costs, how it looks from the air, 314 sites counted.

Browser panel > XYZ Tiles > double-click OpenStreetMap. Then satellite tiles by URL, QuickMapServices, a national WMS, and the ground size of each zoom.

A DSM is the top of everything, a DTM bare ground, a DEM either. On one town tile the DSM made 41% of the ground steeper than 30°, the DTM 7%. 8 free sources.

Connect Trimble receivers directly to Mergin Maps with our new integration. Enjoy a seamless, single-tap setup and full access to high-accuracy GPS data.

Flat, watercolor, pencil and glossy, all rendered from one aerial image of Letchworth Garden City. Every prompt in full, and where the model invented water.

Check OpenStreetMap first. Then four ways to map rooftop PV from aerial imagery in QGIS, with the menu paths and where each one fails.

Start with QuickOSM on leisure=swimming_pool. Where the map is thin, use a segmentation model, threshold the blue, or run a water index. Five methods compared.

Start with QuickOSM: in four French towns OSM held 96 to 98% of paved road length. Where it is thin, five more methods and the line-or-surface choice.

For multispectral imagery, threshold NDVI in the raster calculator, then polygonize. Six methods, what each one needs, and what a canopy layer costs.
