Photogrammetry is a memory and compute intensive process. You typically need a very powerful computer with a lot of memory to get your job done. Even with a good system, the processing times can take very long and they tend to increase exponentially with the number of pictures you add to your photogrammetry project. Also cloud photogrammetry solutions have limitations on the number of pictures they can process.
So don't work hard but work smart!
Process your project in smaller chunks or blocks and merge these different blocks together to one large project in Virtual Surveyor.
Virtual Surveyor has the following tools available:
- Set the order of the different image and elevation terrains. This functionality allows you to control exactly what terrain has preference over the other when they overlap.
- Create clean seams between the different blocks with the clipping tool.
- Optionally export your mosaic to one combined GeoTIFF file. However, we recommend to create your survey, contours or TIN on the virtual mosaic and to export those data to a CAD compatible file format (.dxf, xml, ...).
The Terrain Tools appear when you have selected an image or elevation terrain
- The only limitation is that you cannot create projects that are larger then 250 km (155 miles) in any direction.
