Files

Upload GIS files to Felt with support for multiple formats including Shapefiles, GeoJSON, and KML.

Felt supports a wide range of geospatial file formats with Upload Anything. Upload vector data like shapefiles and GeoJSON to raster imagery and spreadsheets with location information, or import directly from URLs.

You can easily upload data by dragging and dropping files directly on your map or by clicking the icon in the tools section of the toolbar.

Supported file types

Felt supports many raster and vector file formats, up to 5GB in size. Files can be provided in their original format or optionally compressed as .zip, .gz, or .tar.

Vector data

Felt reads most common vector data formats, including:

• ESRI Shapefile (.shp)

• GeoJSON (.geojson)

• GeoPackage (.gpkg)

• GeoParquet (.parquet)

• Geodatabase (folder ending in .gdb, must be zipped)

• KML (.kml) and KMZ (.kmz)

• GPS formats like .gpx, .tcx, and .fit

• ArcGIS Layer Packages (.lpk, .lpkx) and Map Packages (.mpk, .mpkx)

• Other less-popular formats supported by GDAL and GPSBabel

A projection must be provided for formats not using a WGS84 projection.

Raster data

Felt can read raster data like aerial and satellite imagery, Digital Elevation Models (DEMs), surface temperature measurements in a variety of formats:

• GeoTIFFs (.tif, .tiff)

• Raster Geopackages (.gpkg)

• ASCII grids (.asc, .xyz)

• Common image formats like PNG and JPEG if an auxiliary World File (.wld, .pnw, .jpw, etc) is provided.

Check out the Uploading Raster Data & Imagery page to learn more.

Spreadsheets

Felt can read geospatial data from tabular file formats like Excel spreadsheets (.xls, .xlsx), CSV files (.csv, .tsv, .txt, etc), and Numbers files (.numbers).

Check out the Spreadsheets page to learn more.

Images & PDFs

Felt can overlay images and PDFs on a map. Supported formats include .jpg, .png, .heic, .webp, .svg, .pdf, and many more.

AutoCAD

We currently support Drawing eXchange Format .dxf , the 2D file format utilized by AutoCAD's drafting and design services, when exported with geographic coordinates. For instructions on how to export your .dxf for use in Felt, follow along here.

Layer groups

Some file uploads may result in layers with multiple datasets in them. For example, an Excel file with multiple tabs, or a zip file with multiple Shapefiles inside. Read more in Group.

Frequently asked questions

What file size limit does Felt support for uploads?

Felt supports files up to 5GB in size, whether they're uploaded in their original format or compressed as .zip, .gz, or .tar files.

How do I upload files to Felt?

You can upload files in two ways: either drag and drop files directly onto your map, or click the upload icon in the tools section of the toolbar.

Can I upload compressed files to Felt?

Yes, you can upload compressed files in .zip, .gz, or .tar formats. This is optional - you can also upload files in their original, uncompressed format.

What should I do if my vector data doesn't use WGS84 projection?

For vector formats that don't use WGS84 projection, you must provide a projection file with your upload. This ensures Felt can properly display your data on the map.

Can I upload Excel spreadsheets with location data?

Yes, Felt can read geospatial data from Excel spreadsheets (.xls, .xlsx), as well as CSV files and Numbers files. Check Spreadsheets for more details on formatting requirements.

Does Felt support aerial imagery and satellite data?

Yes, Felt supports raster data including aerial imagery, satellite imagery, Digital Elevation Models (DEMs), and surface temperature measurements in formats like GeoTIFF, raster Geopackages, and ASCII grids. See Raster and imagery.

What happens when I upload a file with multiple datasets?

Files containing multiple datasets (like an Excel file with multiple tabs or a zip file with multiple Shapefiles) will create layer groups in Felt, keeping related data organized together. You can upload up to 50 layers within one upload.

Can I upload AutoCAD files to Felt?

Felt supports AutoCAD's Drawing eXchange Format (.dxf) files when they're exported with geographic coordinates. Check the documentation for specific export instructions to ensure compatibility.

Can I upload regular images and PDFs to my map?

Yes, Felt can overlay images and PDFs on your map. Supported formats include .jpg, .png, .heic, .webp, .svg, .pdf, and many more.

What GPS file formats does Felt support?

Felt supports common GPS formats including .gpx, .tcx, and .fit files, making it easy to upload tracks and waypoints from GPS devices and fitness apps.

Do I need special software to prepare files for Felt?

No, Felt reads most common formats directly through GDAL and GPSBabel support. However, for certain formats like Geodatabases (.gdb), you'll need to zip the folder before uploading.

What should I do if my file upload fails?
