Task-oriented documentation for direct map editing, data tables, Processing, Geometry Health, CRS, local and remote sources, export and project recovery.
A current first-session walkthrough of the editor—from opening data to editing, analysing and exporting it safely.

Open guide →Understand the difference between what is visible, filtered and selected—and how those states affect editing and Processing.
Open guide →Create and reshape points, lines and polygons with direct map tools, snapping, topology and Geometry code.
Open guide →Edit typed attributes, calculate fields, build filters, inspect statistics and export clean attribute-only CSV data.
Open guide →Apply single-symbol, category and numeric styling and configure labels without changing source geometry.
Open guide →Run repeatable vector operations with explicit input scopes, non-destructive previews and auditable outputs.
Open guide →Relate features by location, copy attributes, create one output per spatial match and summarise overlapping data.
Open guide →Find structural and topology problems, apply safe cleanup and review shape-changing repairs before creating a repaired layer.
Open guide →Understand source, storage and export CRS, correct misinterpreted coordinates and choose projected processing safely.
Open guide →Keep large layers usable by choosing the right import, visibility, scope, preview and processing strategy.
Open guide →Open common vector formats directly in the browser and understand which formats must remain packaged.
Open guide →Connect directly to ArcGIS services, GeoJSON, WMS and tile sources while keeping local files browser-local.
Open guide →Choose the correct scope and format, export geometry or attributes, and preserve complete work in an EditPolygon project.
Open guide →Understand the mobile drawers, map controls and workflows that differ from the desktop layout.
Open guide →Open KML or KMZ geometry, edit it with the current tools, validate it and export a verified result.
Open guide →Edit GeoJSON visually, work directly with Geometry code, manage attributes, run Processing and export the required scope.
Open guide →Preserve CircleByCenterPoint geometry as centre-and-radius data and understand when polygon conversion is required.
Open guide →Use Processing → Dissolve for repeatable merging, preview the result on the map and understand Polygon versus MultiPolygon output.
Open guide →Use the feature-specific split tool when you need to cut one active polygon with a deliberate line on the map.
Open guide →Drawing, vertex editing and feature-specific geometry changes live on the map.
Attributes, selection, filters, styling, fields, joins and CRS are organised in the Data/GIS interface.
Repeatable scoped analysis and geometry operations run through one Processing Toolbox.
Local files stay in your browser; remote services are contacted directly only when you add them.
