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.

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 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 and only subject to your storage quota.
More detail: What are LAS and LAZ files?
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). 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 (up to 2 GB) alongside your orthophoto; elevation readouts, profiles and volume measurements use this model.
Vectors and CAD
GeoJSON, KML/KMZ, Shapefile (zip) and DXF 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.
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 5 GB and 8K; videos over 200 MB are sent with resumable chunked upload. For GPS synchronization, DJI .SRT or .GPX sidecar files (Insta360, GoPro, Ricoh) are used.
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 makes those conversions easy on your own machine.
What is a token? A monthly processing allowance used by cloud conversions; see pricing for plan details.
