What SiteIQ detects
From OSM and configurable buffers around your site boundary:
- Hard constraints — roads, railways, buildings, water, transmission lines
- Soft constraints — forests and vegetation (optional ignore for early studies)
- Setbacks — default engineering buffers per feature type (editable in app)
Buildable area map
The map shows your full boundary vs the buildable polygon after subtracting constraints. Area (ha) and capacity bands in SiteIQ use buildable area when GIS completes.
Performance
GIS queries run in parallel with multiple Overpass endpoints; results are cached per bbox for faster repeat visits to the same site.
Downstream use
LayoutIQ defaults to packing on the buildable polygon. TerrainIQ slope stats can be scoped to buildable area for more realistic grade numbers on constrained sites.
OSM coverage varies by region. Always validate against cadastral maps, environmental studies, and grid connection plans before land option or permit submission.
