Contour Line Generation from Lidar Point clouds
Tool Created with/for OpenTopography.org
This tool allows environmental researchers, architects, urban planners, ecological planners, and many more of the users of OpenTopography.org to generate contour line shapefiles from Lidar point cloud data, as opposed to the traditional method of surveying. With the advancement and accessibility of Lidar data, this technological advance in contour line generation can now be completed on most areas within North America.
This tool was created with and for OpenTopography.org, allowing users to download contour line shapefiles derived directly from the Lidar point cloud database. The python script uses the TIN interpolation algorithm to generate the DEM, preforms a Gaussian filter on the DEM, and finally outputs the contour lines using GDAL.
