Uploading raster data into Stitch3D is simple and ensures your projects are well-organized and ready for visualization. Follow these steps and guidelines to get started.

Do's & Don'ts

✅ Do:

• Create a project before uploading rasters to a project.
• Use supported file types: .TIF, .TIFF.
• Use a standard CRS with an EPSG code for proper georeferencing.
• Export full-color imagery as RGBA (Red, Green, Blue, Alpha).
• Keep file sizes under 25 GB.

❌ Don't:

• Upload rasters with custom or engineering coordinate systems without a geodetic datum.
• Use YCBCR color space for full-color imagery.

Step 1: Create a Project

Before you can upload data, you need a project space.

1. Click + Project in your Stitch3D dashboard.
2. Enter a Project Name (required) and an optional Description.
3. Under Coordinate Reference Systems:
   • Choose the CRS Unit (International Feet, U.S. Feet, or Meters).
   • Add the Horizontal CRS (e.g., EPSG:26910 for NAD83 UTM zone 10N).
   • Add the Vertical CRS (e.g., EPSG:5703 for NAVD88 height).
   • If you're unsure, you can leave CRS empty and set it later — but defining it now ensures better data consistency and a better overall experience in the platform.

Step 2: Upload Your Data

Once your project is created:

1. Open the project and click Upload Data.
2. Choose Raster from the list.
   • Supported formats: TIF, TIFF.
   • Maximum file size: 25 GB per file.
3. Upload begins immediately, and you'll see progress indicators.

After upload finishes:

• The file is processed to optimize it for fast and efficient viewing in the 2D viewer. During this stage, a processing badge will appear next to the file name.
• Processing time varies and large files can take a while to complete. Most files process and become available in the viewer within 20 min of upload finishing.
• Once processing is complete, you'll receive an email notification confirming the file is ready.
• You can then click on the file inside your project to open and explore it in the 3D viewer.
