# Geo Tools
|
||
|
||
Inspect, convert and analyse geospatial files locally in the browser.
|
||
|
||
Geo Tools is a standalone local-first application in the [add·ideas Toolbox](https://git.add-ideas.de/lotobo/toolbox-portal). Inputs are processed in the browser and are not uploaded.
|
||
|
||
## Version 0.1 scope
|
||
|
||
- Bounded GeoJSON, GPX, KML and coordinate-CSV parsing into a small common model
|
||
- WGS 84 bounds, point counts, great-circle LineString distance and elevation gain/loss
|
||
- Explicit lossy conversion among the four supported formats
|
||
- Iterative Douglas–Peucker LineString simplification and decimal-degree/DMS conversion
|
||
- A coordinate-only local sketch with no map tiles or projection service
|
||
|
||
The common model intentionally supports only Point, LineString and Polygon and preserves only scalar properties. There is no CRS transformation, basemap request or claim of survey-grade geodesy. See [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md) and [docs/PRIVACY-SECURITY.md](docs/PRIVACY-SECURITY.md).
|
||
|
||
## Development
|
||
|
||
Requires Node.js 22 and npm 11.
|
||
|
||
```sh
|
||
npm ci
|
||
npm run check
|
||
npm run test:browser
|
||
```
|
||
|
||
## Release
|
||
|
||
`npm run release:artifact` creates a deterministic `release/geo-tools-0.1.0.zip` and checksum sidecar.
|
||
|
||
## Licence
|
||
|
||
GPL-3.0-or-later. Runtime dependencies retain their own licences; see [THIRD_PARTY_NOTICES.md](THIRD_PARTY_NOTICES.md).
