This page lists everything you can upload to CartaX and the limits that apply, in a single table. Other guides link here for size/limit facts; when limits change, this page is updated first.
Summary table
| Data type | Formats | Upper limit | Processing |
|---|---|---|---|
| Point cloud (raw) | LAS, LAZ | 5 GB / 150 million points | Cloud conversion (tokens)* |
| Point cloud (ready octree) | Potree octree folder | Storage quota (no per-file cap) | Direct registration, token-free |
| Orthophoto (raw) | GeoTIFF (.tif/.tiff) | 3 GB / ~1.5 gigapixels | COG conversion (tokens)* |
| Orthophoto (ready COG) | Cloud Optimized GeoTIFF | Your storage quota | Auto-detected, token-free |
| Orthophoto (tile package) | XYZ (z/x/y) PNG-JPEG folder | 2 GB | Direct registration |
| Elevation model | DSM / DTM GeoTIFF | Your storage quota | Pairs with your orthophoto; elevation & profile queries |
| Vector | GeoJSON | 100 MB / 250,000 features | Processed in the browser |
| Vector | KML / KMZ | 50 MB / 150,000 features | Processed in the browser |
| Vector | Shapefile (.zip) | 250 MB / 250,000 features | Processed in the browser |
| Vector (CAD) | DXF | 40 MB / 25,000 entities | Processed in the browser; incl. text, blocks, circles and arcs |
| Vector (CAD) | Netcad NCN (point list) | Same as GeoJSON | Processed in the browser; point number as label, elevation in the info window |
| 3D model | 3D Tiles (tileset.json + b3dm) | Storage quota (no per-file cap) | Direct registration |
| 3D model | GLB / glTF | 2 GB | Placed on the map |
| 3DGS (Gaussian Splat) | .sog scene or 3D Tiles folder with SPZ | Storage quota (no per-file cap) | Direct registration, token-free |
| 360° collection | Panorama photos (+ position table) | 5 GB (single image 64 MB) | Direct upload |
| 360° video | Equirectangular MP4 | 30 GB / 30 minutes (single file) | Uploaded to streaming infrastructure |
* Cloud conversion requires the Professional plan; these cards are locked on the Free plan. The token-free alternative: run the conversion locally with CartaX Studio and upload the ready output.
Point clouds: LAS/LAZ and ready octrees
Raw LAS/LAZ files are converted in the cloud to a browser-friendly octree format; conversion uses processing tokens (Professional plan) and is limited to 5 GB / 150 million points per file. For larger datasets you have two options:
- Split the data and upload it as multiple layers.
- Convert to an octree on your desktop and upload it as a "ready octree" — this path is token-free. Because it is a folder upload there is no separate size cap; whether it comes from the web dialog or from CartaX Studio, only your storage quota applies.

Orthophotos: GeoTIFF, COG and tile packages
Raw GeoTIFFs are accepted up to 3 GB and ~1.5 gigapixels and converted to COG in the cloud (tokens, Professional plan). If your file is already a COG, it is auto-detected and registered token-free. You can also upload z/x/y tile folders produced by drone software directly (up to 2 GB).
Elevation models (DSM/DTM)
You can add a DSM/DTM GeoTIFF alongside your orthophoto (as a companion file of the Orthophoto card, in the same upload); there is no separate per-file cap, only your storage quota applies. Elevation readouts, profiles and volume measurements use this model. Which one you pick changes the result directly — see DSM vs DTM and volume & cut-fill.
Vectors and CAD
GeoJSON, KML/KMZ, Shapefile (zip), DXF and Netcad point-list (NCN) files are processed entirely in the browser — your data is drawn straight onto your map without a processing round-trip to a server. The feature-count limits in the table keep the map fluid. Working in Turkey, you can also pull cadastral boundaries in without uploading a file (on paid plans, with a Turkey location) — see TKGM parcel queries. For Netcad drawings, follow Bringing a Netcad project into CartaX.
360° panoramas and video
Panorama collections (photos + an optional JSON/CSV/Excel position table) upload up to 5 GB in total; positions are read from EXIF first. 360° videos are supported up to 30 GB and 30 minutes per file; videos over 200 MB are sent with resumable chunked upload. For GPS synchronization, DJI .SRT or .GPX sidecar files (Insta360, GoPro, Ricoh) are used — see syncing 360° video with GPS.
Common questions
My file exceeds a limit — what now? For point clouds the ready-octree path, and for orthophotos the ready-COG path, allow much larger data within your storage quota. CartaX Studio runs those conversions on your own machine and uploads the output subject only to your storage quota.
What is a token? A processing allowance used by cloud conversions. The Professional plan's monthly tokens renew every month and do not roll over; purchased token packs, on the other hand, are permanent. Scale: 1 token ≈ 40 million points for LAS/LAZ conversion. See pricing for plan details.
