Troubleshooting

Install and run PWAs (like Field Data Kit) on HTTPS or http://localhost. If you open files via file://, browsers block Service Workers. Use a simple local server (e.g., python -m http.server) during development.

Browsers have memory limits. Prefer COG rasters or vector tiles for large areas; use the Simplify / TopoJSON tool for complex vectors; close heavy tabs; try Chrome/Edge for best performance.

Ensure script order matches each tool’s HTML. For local copies, host the vendor file in /assets/vendor/… and reference it with the same path used in the page.

Confirm columns named lat/lon (or y/x). Check decimal separator and CRS (WGS84) unless you’re using a reprojection step.

Enable “Include legend” if needed; allow cross-origin images (CORS) for external tiles; wait a moment for tiles to render before export.

If ad blockers are enabled, only placeholders may show. Apps keep working. For sponsorships, contact info@geolayers.co.za.

Data privacy

Most tools run entirely in your browser—your files don’t leave your device unless you choose to upload them to an external service. Client-side storage uses your browser’s IndexedDB/localStorage for saved app state.
