Digital California topographic maps index

A recent addition to the digital map collections at the Earth Sciences and Map Library is a scanned copy of the California 15 and 7.5 minute topographic quadrangles index map. The index map displays the names of both USGS series quads over a map of the state. The map is very large and scanned in two images, one for the northern part of the state, one for the southern section. You can use this online index to determine the names of topo quads for an area of interest in California.

Other online resources for topographic maps include the HISTOPO project, that includes digitized topographic maps of the Bay Area, the Monterey area, and select 30 and 60 minute topographic maps around the state.

The Earth Sciences and Map Library's digital topographic map collection is a list of topographic map sets from around the world. Many of these sets have scanned indexes that are viewable online. Individual map sheets are available for use in the library. Most maps circulate for one week.

Please use the eReference service or contact the Earth Sciences and Map Library if you have questions or need help using these online resources.

Jenny LeeIt'd really cool to overlay it over Google maps, or create some kind of heatmap.

TomIt will very interesting to see if you could do a comparison of the topography before and after an earthquake to see the change.
