Obtaining Digital Aerial Photograph Files
If viewing the photo on the internet is not sufficient, the library has access to aerial photo sets and can provide digital files to Cal Poly students. For assistance, check the GIS help hours posted near the GIS workstations in the Reference Room. You can also access this data yourself on computers found in GIS labs. In addition to the dedicated workstations in the Reference Room, GIS is accessible in the learning commons on the 2nd floor (rooms 217C and 217D).
