Prepare GeoJSON for TrueGIS and Web GIS Workflows

Reading time: ~6 min

Whether you export from QGIS or generate data with GeoPandas, a tidy GeoJSON makes your web maps faster and your Scaled Print outputs cleaner.

Export tips

• Simplify geometries (but keep topology) to reduce size.
• Use EPSG:4326 for broad web compatibility.
• Remove unused attributes to shrink payloads.
• Validate with a linter to catch geometry errors.

Styling for print

• Prefer thin strokes and semi-transparent fills.
• Use high contrast against your basemap.
• Preview with Show Print Area before exporting.

From data to result

1. Create or clean your data in QGIS/GeoPandas.
2. Export to GeoJSON and load in your web map or annotate in TrueGIS.
3. Use Scaled Print for predictable output at 1:5,000, 1:10,000, etc.
