# Files

GISOwl accepts a wide range of geospatial and tabular file formats. Drag and drop files onto the map or click **Upload** in the toolbar.

## Supported Vector Formats

| Format | Extensions | Notes |
| --- | --- | --- |
| GeoJSON | `.geojson`, `.json` | Recommended for web workflows |
| Shapefile | `.zip` containing `.shp`, `.dbf`, `.shx`, `.prj` | Must be zipped together |
| KML / KMZ | `.kml`, `.kmz` | Google Earth format |
| GPX | `.gpx` | GPS track and waypoint data |
| GeoPackage | `.gpkg` | OGC standard, multi-layer support |
| TopoJSON | `.topojson` | Topology-encoded GeoJSON |
| FlatGeobuf | `.fgb` | Fast streaming format |

## Supported Raster Formats

| Format | Extensions | Notes |
| --- | --- | --- |
| GeoTIFF | `.tif`, `.tiff` | Cloud-optimized (COG) recommended |
| MBTiles | `.mbtiles` | Pre-tiled raster or vector |
| JPEG 2000 | `.jp2` | Satellite imagery |

## Supported Tabular Formats

| Format | Extensions | Notes |
| --- | --- | --- |
| CSV | `.csv` | Must include lat/lon or WKT geometry columns |
| Excel | `.xlsx`, `.xls` | First sheet used; needs lat/lon or address columns |
| TSV | `.tsv` | Tab-separated values with coordinates |

## Upload Limits

File size limits depend on your plan. Free accounts can upload files up to 50 MB. Pro accounts up to 500 MB. Team and Enterprise accounts up to 2 GB. Files larger than these limits should be uploaded via cloud source connections.

## Auto-Detection

GISOwl automatically detects coordinate reference systems (CRS), geometry types, and column mappings. If auto-detection fails, you'll be prompted to select the correct CRS and map columns manually.
