Overview
Stitch3D supports a wide range of spatial and non-spatial file formats across point clouds, raster imagery, vector data, media, ground control points, and project documents. All files are validated on upload to ensure format correctness and processing readiness. For georeferenced projects, files are automatically reprojected into your project's CRS on upload.
☁️ Point clouds
Point clouds are the primary data type on Stitch3D. The following formats are supported for upload and 3D visualization in the viewer.
💡 Tip: If you have .las files, try converting them to .laz before uploading. LAZ is lossless (no data is lost) and files are typically 80–90% smaller, resulting in significantly faster upload times and lower storage usage.
ℹ️ Note: Stitch3D does not accept zipped point cloud files. Upload bare .las, .laz, .e57, or
.ply files directly.
🗺️ Raster
Raster files are displayed as map layers in the viewer, overlaid on or alongside your point cloud data.
ℹ️ Note: For GeoTIFF files in a georeferenced project, ensure your file is in a supported EPSG-registered CRS. Stitch3D will validate and reproject it into your project CRS on upload.
📐 Vector
Vector files are visualized as layers in the viewer and can be used for boundaries, planimetrics, contours, and spatial overlays.
⚠️ DXF files without a .prj file may not display in the correct spatial position in the viewer. Always include a .prj alongside your .dxf when uploading CAD-derived data.
ℹ️ Not yet supported: .dwg and .dgn files are not currently supported. Convert to Shapefile or DXF before uploading.
📷 Media
Media files can be uploaded to a project as reference assets such as inspection imagery, site photographs, and 360 panoramas.
💡 Tip: If your site photos were taken with a GPS-enabled camera or drone, the EXIF geotag data is preserved on upload and images will be pinned to their capture location automatically in the viewer.
📍 Ground Control Points (GCPs)
Ground Control Points are used in georeferenced projects to improve the spatial accuracy of your point cloud data. GCPs must be uploaded as a CSV file in a specific format.
ℹ️ Note: GCP upload is only available in Georeferenced projects. Quickstart projects do not support GCPs.
📄 Documents
Non-spatial project documentation can be uploaded and stored alongside your spatial data, keeping everything in one place.
ℹ️ Note: Document files are stored as project assets and are available for download. They are not visualized in the viewer.
File size and upload limits
💡 Tip: If you're uploading very large point clouds, convert to .laz first.
