I have Lidar data which contains multiple .las files for an entire quad. I have figured out which .las is the area I am looking for. I was told the data is in 1.4 meter resolution and would work to create a contour map with 1 foot intervals. So that's what I have to work with.
I am not sure what the 1.4 meter resolution means or how it helps to create 1 foot intervals. Would the first step be to use the
las2dem tool? And what would I set the step size/pixel size to?
I have created a DEM by inputting my .las file, no filter, pixel size:1. I then used
raster>extraction>contours and input my DEM with interval set to 1. Is this correct for 1' intervals, or is there something I need to do to compensate for the 1.4 meter resolution of the .las?
I am mostly confused on how to make sure the intervals are set to 1 foot and not 1 meter, and what the 1.4 meter resolution means.
Also, I am working in QGIS and using the LAStools set.
