webgeods — Articles

Interactive articles on spatial data science, with runnable Python and R examples built in, not just diagrams. The standalone tools distill the same checks without the reading.

Spatial Data Quality

Interactive articles that explain a spatial problem properly — the same map, the same runnable Python and R code, compared side by side. Need just the answer, not the full explanation? The standalone tools run the same checks directly.

Inspect → Validate → Check Topology → CRS Inspector (planned)

First Look at a Geospatial File: What to Check Before You Trust It

Upload a GeoJSON or a Shapefile and get an instant summary — feature count, geometry type, CRS, bounds, attributes, invalid/empty/duplicate geometries — in Python and R on the same map.

Topology Errors in a GeoJSON: Detect Without Fixing

Upload a GeoJSON and find overlaps, gaps, slivers, duplicates and dangles — a report, not an automatic repair, in Python and R on the same map.

Geometry validity: find and understand invalid geometries

An interactive lab with Python, R and MapLibre — upload a GeoJSON, find out which geometries are invalid and why, compare how the two languages diagnose the same problem. Repair is a separate, optional step.
