Archiving digital maps

  1. 1. Archiving Digital Maps By Noreen Whysel LIS 651 Information Professions
  2. 2. Digital Preservation “…the world has in some ways a better record of the beginning of the 20th century than of the beginning of the 21st.” -- Adam Farquhar, British Library
  3. 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.
  4. 4. Cataloging and Preserving GIS Data Catalog record Citation Storage/format issues Ownership Privacy Security Historic significance
  5. 5. Cataloging a Map  Traditionally:  Paper Maps  Bound in Atlases  Catalog RecordFull Title: Map of the States Of Ohio Indiana & Illinois And Part Of MichiganTerritory Compiled from the Latest Authorities.

Philadelphia: Published By Anthony Finley, At The North-East Corner Of Chestnut And Fourth Streets. 1826.Publication Author: Finley, AnthonyPublication Date: 1826Publication Reference: P1378; Howes F140; NMM 485.Publication Note: This atlas was Finleys attempt to compete with Henry Tanners 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 "Finleys American Atlas" in gilt.

  7. 7. Cataloging Digital Maps Born Digital Maps:  Database input  Software output  Electronic format  Dynamic  Interactive 3-5 meter sea level rise; Population: 1,537,195 Data Source: USGS 10M NED Maps are based on LIDAR data, USGS 10m NED. Maps are illustrative; areas in blue depict various potential inundation scenarios.  Map accuracy is dependent on the accuracy of the geospatial data.

  15. 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. 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.
  17. 17. Data Preservation Models NYS GIS Clearinghouse  Share creation, use and maintenance of GIS data GISMO Data Advocacy Policy (1999)  Standards, efficiency, accessibility, sharing LOC’s National Digital Information Infrastructure & Preservation Program (2000)  Preservation architecture standards North Carolina Geospatial Data Archiving Project (2000)  Collaboration between university library and state municipalities, demonstration for other regions
  18. 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. 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.
