Process a single LiDAR file
The simplest way to use Cassini is to pass a single LiDAR (an acronym of “light detection and ranging” or “laser imaging, detection, and ranging”) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.cassini process subcommand:
cassini process path\to\my\tile.lazcassini process ./path/to/my/tile.lazcassini process ./path/to/my/tile.lazIt will generate a png map in the Dots per inch (DPI, or dpi) is a measure of spatial printing, video or image scanner dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch (2.54 cm). Similarly, dots per centimetre (d/cm or dpcm) refers to the number of individual dots that can be placed within a line of 1 centimetre (0.394 in).tile directory (you can specify the out directory with the --output-dir argument). The map default resolution is 600
If you are not happy with the result (too few cliffs, too much green…), you can modify the configuration and re-generate the map while skipping the LiDAR preprocessing step (which is the most time consuming part) with the cassini render subcommand. Check the configuration reference to learn more about all the configuration options.
