GIS Data

Here are some GIS data… Some of the links are being repaired…

GIS elevation

lidar

• 1m dem – usgs rocky
• 1m dem – usgs aws
• LPC – usgs rocky
• LPC – usgs aws
• LPC – usgs rocky legacy
• LPC – usgs aws legacy

lidar download details

• To download files from these usgs urls, one simply download u-get to their computer (click the green download button), download the text file that lists all the files (at the url for the data one wants), then load this text file into u-get.
• Here are step-by-step instructions for doing this.
• For example for this dataset “CA_NoCAL_Wildfires_B4_2018,” the tiff files are here, and the text file is at the top of this directory here. Use this text file to download all the tiff files in that project. If one only wants to download a portion of these files, they could edit the text file.

• Southern Cascadia – 30m (Dartnell et al., 2021)
