Project Title: California in Maps over the Web
[instructions for filling out forms deleted]
Needs-assessment process and needs: The most heavily used maps in many libraries are the California topographic sheets – both current and historic; in color - issued by the U.S. Geological Survey (USGS) since the late nineteenth century; all of these maps are uncopyrighted. User needs for the most current edition of each 1:24,000-scale topographic sheet are met by the Digital Raster Graphics (DRGs), which are available in digital form over the Web via the Alexandria Digital Library (ADL) Catalog, at http://webclient.alexandria.ucsb.edu; and the Earth Sciences and Map Library of the University of California at Berkeley has kindly made available via the Web the scanned images of ca. 350 historic USGS topographic quadrangles at http://sunsite.berkeley.edu/histopo.
The object of this proposal is to have scanned all the historic 1:24,000-scale sheets for the state, and all the USGS sheets of the state at scales of 1:62,500 (15-minute quadrangles) and 1:125,000 (30-minute quadrangles) – except for the Bay area, which as noted has already been done. The scanned maps all will be served out via the ADL Catalog, to all users. Thus all users would have access via the Web to three complete series of USGS topographic maps. This at the same time allows libraries holding the hard-copy maps that are in fragile condition – e.g., almost all the maps published prior to 1940 – to refer users to the digital version so that the hard-copy versions are less frequently handled.
Client/community involvement: This project has been discussed amongst the University of California and Stanford map libraries for a few years; librarians from local libraries in the Santa Barbara area and a local non-university user of maps were asked if they perceived this as a useful project, and agreed that it would be helpful to map users of the state.
Outline of plan: The object of this proposal is to have scanned all the historic 1:24,000-scale sheets for the state, and all the state sheets at scales of 1:62,500 (15-minute quadrangles) and 1:125,000 (30-minute quadrangles) – except for the Bay area, which as noted has already been done. The combination of the most current edition of 1:24,000-scale sheets of the states, plus the historic sheets of the Bay area, leaves approximately 3,000 sheets of California (older editions of the 1:24,000-scale series; all editions of the 1:62,500-scale and 1:125,000-scale sheets) not yet available over the Web. The Davidson Library has already had sample scans of three maps at different scales done by two different commercial firms and also by a large-format scanner owned by the UCSB Geography Department. After looking into the prices of large-format scanners and the amount of staffing, space, and maintenance required by such scanners, and checking that against the cost of hiring a firm to do the scanning, it became obvious that the former is the more logical choice. The procedure will be as follows: Project Title: California in Maps over the Web Jurisdiction: University of California, Santa Barbara 9. Project Summary: continued. Complete in space provided; do not attach additional sheets. a. Select a commercial firm which is already familiar with map scanning to do the scanning. Depending upon which firm is selected, either the sheets will be mailed to the firm (estimated to be about $900), or the firm will scan sheets available to it through a USGS Library, near which the firm is located. While cost per scan varies from company to company, $11 per scan is about the average, which will be $33,000 (3,000 maps x $11/map)
b. The scans – probably 250 or 300 dpi, 8-bit or 24-bit color - will be delivered to the Davidson Library, probably via ftp but possibly via some form of high-density computer media. Thumbnail, browse, and one form of speedy distribution of the full file (e.g., LizardTech’s Mr. SID © ) will be generated.
c. Metadata will be created by the Davidson Library, using the headers for each file as a base.
d. The Davidson Library already has in place an extensive computer infrastructure for serving out digital geospatial data. Thus, no purchase of computer software will be required, and the only computer equipment that would need to be purchased are a server and disk to serve out the data; these will be set up when they arrive. While computer prices change rapidly over time, the estimate for cost of server and disk is $16,000. The metadata and the data will be loaded into ADL.
e. Appropriate publicity to announce the availability of the digital versions of the maps will be issued. The Davidson Library will follow the guidelines provided in the California State Library Digitization and Metadata Standards; for metadata, fields specific to geospatial data (such as coordinates, and scale of original item) will be added.
Staffing required for this, judging from the Davidson Library’s previous experience with large geospatial datasets (e.g., DRGs – ca. 3,300 digital files) will be approximately: two months’ time from one Computer Network Technologist II, two Computer Network Technologist III, one Laboratory Assistant II and one Librarian; and 15 hours per week of student-assistant time for six months. This averages out to about $35 per scan ($11 per scan for the scanning of each map by the commercial firm; $24 for the data manipulation and metadata creation).
Long-term prospects for project continuation and/or continued benefits: Every effort will be made to get all historic topographic sheets for the state scanned and online. Should it develop that some have been missed, the Davidson Library will work on getting these missing sheets scanned and added to the collection.
