The LAR-IAC project encompasses the entire land area of Los Angeles County in mainland plus Catalina Island. The Area of Digital Elevation Model data developed over the Urban/Suburban area mainland covers approximately 4214 square miles. Tiles were downloaded in September, 2025 from the USGS National Map:  <\/SPAN><A href=\"https://apps.nationalmap.gov/lidar-explorer/\" target=\"_blank\" STYLE=\"text-decoration:underline;\"><SPAN>https://apps.nationalmap.gov/lidar-explorer/#/<\/SPAN><\/A><SPAN>.
