We extract bare earth using tscan and across section in a large scale while manually as well as automatically. Some example after editing is given here. We have also given a view of 5m DTM surface after classification thus processed in a small scale, presenting the quality of our bare earth.
From same bare earth we extracted contours at 1m or 0.5m where terrain is hilly or plains and a part of the area of the project with 1m contours thus extracted is as given here on a larger scale presenting quality in bare earth and in contours.
We extract the vector line manually as per client’s required accuracy (both horizontal & vertical) using Tscan intensity raster images or else provide orthophotos. Below mentioned presentation view is our latest one where we did extract the road center line’s from bare earth.
