Wolkflow:
– Step 1: Capture images
Take photos from the ground or use any UAV to capture aerial terrain images. Use 3Dsurvey software with its FREE support to produce the best point clouds, DSMs and orthophotos.
Input file format: images – *.jpg, Ground Control Points – *.txt

– Step 2: Import into 3Dsurvey
Let 3Dsurvey do all the hard work. It independently recognizes ground control points in your imagery and generates a georeferenced point cloud with realistic colors and shadows. Set the level of reconstruction yourself to control the processing time.
Output file format: *.ply, *.las

– Step 3: Calculate a Digital surface model
Use 3Dsurvey’s smart tools and manipulate your point cloud to produce the best digital surface model. Calculate volumes and generate profiles quickly and efficiently.
Output file format: *.xyz and geoTIFF

– Step 4: Generate an Orthophoto
Automatic generation of high-quality orthophotos based on a digital terrain model and aerial imagery. Extract all the information you need and speed up your survey map creation in a fast and efficient fashion.
Output file format: *.tiff, *.jpg and a georeferenced data file
