Archiving digital maps

This document discusses cataloging and preserving digital maps and geographic information system (GIS) data. It begins by explaining how born-digital maps are different from traditionally paper maps in that they are stored in databases and have dynamic, interactive features. It then provides examples of metadata standards and catalog records for maps, as well as citations for digital maps and datasets. Models for preserving and providing broader access to GIS data are presented, such as data clearinghouses and open data initiatives. The importance of archiving digital geospatial data and challenges involved are also addressed.

- 3. “Born Digital” Documents Software produces digital documents. (Photos, infographics, maps) The data often exists in databases on the computer, on the internet or otherwise “behind the screen.” The software output exists on screen and is very easy to share electronically. The knowledge output – the Information - is preserved in the saved file, or can be printed or saved to a PDF or image file.

Publication Author: Finley, Anthony Publication Date: 1826 Publication Reference: P1378; Howes F140; NMM 485. Publication Note: This atlas was Finley's attempt to compete with Henry Tanner's American Atlas - the maps are grouped in much the same arrangement as Tanner used and the cartography and engraving are equal to Tanner, although the scale and map size are smaller. There are only two issues that we have seen, both dated 1826 on the title page, but with different dates on the maps. In the first issue, the maps are dated 1824-26; in the second issue (this copy) the maps are dated 1826-27. Finley continued to publish the maps as pocket maps until 1831 when he sold his map and atlas copyrights to Mitchell, who reissued this American Atlas only once, in 1831 (see our #3884) but continued to issue the pocket maps, with updates, until about 1850. Bound in half leather marbled paper covered boards with red leather label stamped with "Finley's American Atlas" in gilt. Full color.

- 15. Who Uses Geographic Data? Historians use GIS data for research and teaching processes in complex, dynamic, nonlinear systems. Economists also like the ability of GIS to present clear visualizations in a familiar way. Information architect, Richard Saul Wurman, and information visualizer, Edward Tufte, are both great proponent of maps for presenting information in a way that Wurman has said helps to “make the complex clear.”
- 16. Who Archives Geographic Data? Library of Congress Geography and Map Division holds the world’s largest cartographic collection: 5.5 million maps 80,000 atlases 500 globes and globe gores 3,000 raised relief images 20,000 digital files “Traditionally, the Geography and Map Division has acquired the completed map. Today, the need to acquire the layers of data from which a map can be made takes increasing priority.” --Hebert, John, Geography and Maps Division, Library of Congress.

- 18. Data Preservation Models The objectives of the the North Carolina Geospatial Data Archiving Project are: Identification of resources Acquisition of at-risk geospatial data Development of a digital repository architecture for geospatial data, using open source software tools Enhancement of existing geospatial metadata with additional preservation metadata, using Metadata Encoding and Transmission Standard (METS) records as wrappers Investigation of automated identification and capture of data resources using emerging OGC specifications for client interaction with data on remote servers Development of a model for data archiving and time series development.
- 19. Broader Access to GIS Data New York City Open Data Mandate, March 2012 1. The Department of Information Technology & Telecommunications must post on its website a technical standards manual, which will help agencies make their public data available to the greatest number of users and for the greatest number of applications. 2. Within a year, each agency must convert all of its public data sets that are currently online in “locked” formats into formats that enable computer programmers to use the data to build applications. 3. Within 18 months, the Department of Information Technology and Telecommunications will work with each agency to post a compliance plan, describing all of the public data sets in each agency’s possession. The plan will be then be updated each year, and will serve as a roadmap for agencies to post these datasets to a single Web portal by 2018.
