Supported file types
See which file formats you can upload to Felt, from Shapefiles and GeoTIFFs to spreadsheets and CAD drawings, and what to do with files Felt can't read.
Use Upload Anything to add vector and raster data, spreadsheets, CAD drawings, GPS tracks, images, and PDFs. Upload files directly or in a .zip, .7z, .rar, .tar, or .gz archive. To add data from a link instead, see Add data from URLs. For file size and other caps, see Data limits.
Vector data
Shapefile
.shp with .shx and .dbf, and usually .prj. Upload the parts together or in one .zip file.
GeoJSON and newline-delimited GeoJSON
.geojson, .json, .geojsonl, .geojsons, .geojsonseq
GeoPackage
.gpkg
GeoParquet
.parquet
File Geodatabase
A folder ending in .gdb. Zip the folder before you upload it.
KML and KMZ
.kml, .kmz
ArcGIS layer and map packages
.lpk, .lpkx, .mpk, .mpkx
OpenStreetMap extracts
.osm, .osm.pbf
GPS tracks and waypoints
.gpx, .tcx, .fit, .gpi
CAD drawings
.dxf, .dwg. See AutoCAD.
Felt also tries other vector formats that GDAL reads. If one doesn't work, convert it to GeoPackage or GeoJSON. When a vector file has no projection information, Felt assumes latitude and longitude (EPSG:4326).
A KML or KMZ file with several folders uploads as a layer group with one layer per folder. Felt doesn't keep the file's colors or icons, so style the layers in Felt after you upload.
A GPX, TCX, or FIT file creates a layer for each kind of data it contains: tracks as lines, and track points and waypoints as points. Files with several kinds of data create a layer group.
AutoCAD
To place an AutoCAD drawing accurately, assign an earth-based coordinate system, such as an EPSG code, and draw at real coordinates in that system before you upload the drawing to Felt. Otherwise, Felt guesses the location from the drawing's extent. Felt may skip objects from AutoCAD vertical products, such as Civil 3D surfaces. To keep them, explode them into plain AutoCAD geometry before you save the drawing.
Raster data
Raster data includes aerial and satellite imagery and elevation models (DEMs, DSMs, and DTMs).
GeoTIFF and Cloud Optimized GeoTIFF (COG)
.tif, .tiff
Raster GeoPackage
.gpkg
ASCII grid
.asc, .xyz
PNG or JPEG with a world file
.png or .jpg with .pgw, .jgw, or .wld. Upload both files together.
Virtual Raster (VRT)
.vrt. The source rasters it references must be reachable online. See VRT mosaics.
See Raster and imagery.
Spreadsheets
Felt reads Excel (.xlsx, .xls, .xlsm), CSV and other delimited text (.csv, .tsv, .psv, .txt), and Apple Numbers (.numbers) files. To place rows on the map, include coordinates, addresses, or place names or codes. A spreadsheet without location columns becomes a table you can join to another layer. See Spreadsheets and geocoding.
Images and PDFs
Images and PDFs upload as image annotations, not as data layers, so you can move, resize, and rotate them on the map. Felt reads JPEG (.jpg, .jpeg), PNG (.png), HEIC (.heic), WebP (.webp), SVG (.svg), PDF (.pdf), and other common image formats. Images have a smaller maximum size than data files. See Data limits.
Felt places each image where you drop it. When photos have GPS location data, such as in the file's EXIF metadata, Felt shows Images have location data. Click Move to location to move each photo to where it was taken.
Felt doesn't georeference an image or PDF from control points, and doesn't read coordinates stored in a PDF. To place a scanned map or plan at exact coordinates, georeference it in QGIS or other GIS software first. Then upload the GeoTIFF (.tif), or the PNG or JPEG with its world file (.pgw, .jgw, or .wld), as raster data.
Formats Felt doesn't read
QGIS project and style files (.qgs, .qgz, .qgd, .qml, .qmd, .qlr)
They hold project settings and styles, not data
The data files, or add them with the QGIS plugin
ArcGIS layer files (.lyr, .lyrx)
They point to data stored elsewhere
The Shapefile or geodatabase they point to
Enhanced Compressed Wavelet (.ecw)
Proprietary raster format
A GeoTIFF export
Word and PowerPoint files (.docx, .pptx)
Not geospatial data
A spreadsheet or geospatial file
Illustrator files and other non-geographic vector graphics (.ai)
Their shapes are drawn on a page, not at locations on Earth, so they can't become a data layer
A GeoPackage or Shapefile exported from GIS software, or a .png or .svg image to place as an annotation
