Your first estimate

  1. Check the model status. The pill in the header should say Model online. If it says waking up, the GPU Space is starting; wait about a minute. If it says unreachable, see Troubleshooting.

  2. Open an image. Drag a file anywhere onto the window, click the drop zone in the Project panel, or use File → Load / Open (Ctrl+O).

    Format Notes
    GeoTIFF Preferred. CRS and pixel size are read automatically, and absolute DSMs are possible
    PNG / JPG Fine for screenshots. Set the resolution yourself
    .dwproj, .zip, .npy Reopen a saved project or a result bundle without running inference

    Want to try it first? File → Sample scenes loads a bundled Cartosat-2S campus scene.

  3. Set the resolution. In Resolution (m/pixel), choose Auto (from the file), 0.3, 0.5, 0.6 or 1.0, or Custom (0.05–30). The card shows where the value came from.

  4. Choose quality. Higher quality (TTA) averages 8 rotated and flipped copies of every tile. It is slightly more accurate, takes 1–2 min instead of 15–45 s, and uses more GPU quota.

  5. Click Estimate heights. An overlay shows the stages: Connecting → Uploading → Waiting in queue → Estimating heights (GPU) → Downloading results → Building 3D mesh, with elapsed time. The previous result stays visible underneath, and you can Cancel at any time.

  6. Read the result. The Project panel summarises the new result:

    Field Meaning
    Height range Minimum and maximum height above ground
    Mean / median Typical height; the median is usually near 0 m on open land
    Share below 1 m Share of flat pixels. Nadir urban scenes usually have 40–70 %
    Grid · source Output size and where the GSD came from

  7. Explore. Orbit with the mouse, switch views with 1 2 3, and hover for heights. Continue with Navigating in 3D.

What happens to georeferenced scenes

Section titled “What happens to georeferenced scenes”

If the image is georeferenced and auto-anchor is on (Inspector → Info), DepthWizard fetches coarse terrain tiles right after the run and converts the result to an absolute DSM. The product chip changes from nDSM to DSM. See Elevation anchoring.
