Import from OpenStreetMap

Pulls features in your current map view via Overpass API.

Tip: zoom to a neighborhood — city-wide queries may time out.

Import from Overture Maps

Loads the selected Overture theme from PMTiles for the current map view.

Overture data is a monthly release; loading is limited to the visible tile range.

◉ Buffer All

Distance buffer around each feature.

Dissolve overlapping buffers

≋ Contour lines Terrain

Elevation contours from open DEM data (AWS Terrain Tiles). Output carries elevation as a Z value and an elev attribute.

Area

Interval (m)

◈ Overlay Polygons

Combine two polygon layers geometrically.

Layer A Layer B

✂ Extract & clip

Source layer

Uses the source layer's active filter (⧩ Filter on the layer).

Mask / reference polygons

⊞ Aggregation

Combine features within a layer.

Dissolve polygons Spatial join (points → polygons)

⬡ Geometry

Source layer

🕸 Network Lines

Turn a line layer into a clean segment network — split at every intersection — ready for routing and space syntax.

Remove dangling stubs shorter than (m, 0 = keep all)

Service area — everything reachable within a network distance

⇄ OD matrix Points

Travel-time table between two point layers via OpenRouteService (your free key, max 10 × 10). Writes nearest-destination columns to the origins and downloads the full matrix as CSV.

Origins Destinations Profile

◖ Isovist Polygons

Visibility polygon from a point, blocked by polygon obstacles (building footprints). Classic space-syntax companion.

Obstacles layer Viewpoint

Max view distance (m)

⌘ Space syntax Lines

Segment analysis (Hillier/Iida): integration, choice, NACH/NAIN. Run Prepare network first, then analyse the segments layer. Results are written as ss_* columns and auto-styled red (high) → blue (low).

Weighting Radii (comma-separated, “n” = global)

Stops between (optional, one “lat, lon” per line, max 3)

⬢ Hex density Points

Hexagonal grid counting points per cell — an instant density map. Style the result by its count column.

Cell size

Drop empty cells

𝑓 Geometry columns

Write each feature's measurements into the attribute table: area (m² / km²) for polygons, length (m / km) for lines, lon/lat for points.

⇢ Nearest neighbor Points

For every point in the source layer, the distance (m) to the closest point in the target layer — e.g. "distance to nearest bus stop".

Source points Target points

⏱ Isochrones Points

Travel-time polygons around point features (via OpenRouteService).
