[less]

Abstract:	For 20 years, David Rumsey assembled a collection of more than 150,000 historical maps of the Americas and the world. Motivated by a desire to make his private map collection a free public resource, Rumsey then created an online map library, http://www.davidrumsey.com/, which currently has over 10,000 high resolution images of maps from his collection. He has also built a suite of tools for users to experience and interpret the maps online. These include GIS, which allows users to combine historical maps with modern geospatial data to see change over time. The online map collection can be accessed over the Internet from search engines, library catalogs, GIS databases and many other entry points. Rumsey continues to add new content to the online collection and develops new tools that improve both the user experience and the online library architecture.

Mapping under the Third Reich: Nazi Restrictions on Map Content and Distribution

Monmonier, Mark (ALA Map and Geography Round Table, January 31, 2005)

[more]

[less]

Abstract:	A 99-page 1947 State Department report discovered in the NOAA Central Library summarized sixty map-related regulations issued by the German government between July 1934 and June 1944. Although the Third Reich pursued cartographic unification and uniformity more vigorously than earlier central governments, regional diversity and the distractions of a multi-front war hindered attempts to standardize map series and develop a national base map at 1:5,000. Pragmatism trumped propaganda when Nazi rule-makers decided to retain Latin lettering for maps, rather than require the more ornate German script used in official government publications and strongly promoted for books and newspapers. Official mapmaking had numerous niches in diverse government departments. In restricting distribution of detailed maps to the public, Nazi cartographic policy recognized the importance of scale by drawing a sharp line at 1:300,000. Covering both large- and small-scale products, a 1937 law gave the Ministry of the Interior authority over private mapmakers, who now had to conform to official policy on geographic names as well as the colors used on political maps.

Warping Waldseemüller: A Cartometric Study of the Coast of South America As Portrayed on the 1507 World Map

Hessler, John (ALA Map and Geography Round Table, August 29, 2005)

[more]

[less]

Abstract:

In an attempt to shed some light on the problem of Martin Waldseemüller’s portrayal of the shape of South America on his important 1507 world map, polynomial warping algorithms and regression analysis are applied to the coastlines of South America on his map and the known coastal outline. Correlation coefficients are calculated and regression curves are analyzed for inflection point behavior in order to quantitatively compare the geometries of both coastlines. High correlations have been found between both shapes suggesting the possibility of Waldseemüller’s use of empirical data in mapping the South American continent rather than pure chance.

Unlocking the Mysteries of the Bounding Box

Caldwell, Douglas R. (ALA Map and Geography Round Table, August 29, 2005)

[more]

[less]

Abstract:

Few geospatial data representations are more basic than the bounding box; a rectangle surrounding a geographic feature or dataset. Bounding boxes are a key component of geospatial metadata and lie at the heart of many computational geometry algorithms as well as spatial indexing systems. Despite their ubiquity and common use, bounding boxes are more complicated than they first appear. The phrase that ‘spatial is special’ applies to this humble representation as well as to more sophisticated geospatial representations. This paper explores the nuances of correctly understanding, using, and interpreting bounding boxes.

French Mapping of New York and New England, 1604-1760

Allen, David Y. (ALA Map and Geography Round Table, October 9, 2005)

[more]

[less]

Abstract:

This article focuses on colonial-era French mapping of the region between the French and British settlements in what is now the northeastern United States. This area was largely dominated by Iroquoian and Algonquian Indians, many of whom were allied with the French. In comparison to to the Dutch and British colonists, the French produced remarkably detailed and accurate maps of this region. These maps contain a wealth of information about Indian settlements, trade routes, and military activities during the colonial period.

Ptolemy’s Revenge: A Critique of Historical Cartography

Schafer, Wolf (ALA Map and Geography Round Table, November 16, 2005)

[more]

[less]

Abstract:

This article calls for a new approach to historical cartography. Arguing that cartographic presentism obscures the local geographies of the past, the author reviews the imagery of current historical mapping as geocentric and presentistic. The analysis concentrates on two key images: the ubiquitous image of the globe as the icon of the present and David Harvey’s “time-space compression” chart. Harvey’s paradigmatic diagram and an earlier data map by Eugene Staley are discussed as misleading representations of globalization. The article envisions the alternative of a richer historical cartography that would combine the scientific purview of modern reference maps with historical maps and preglobal perspectives of space.

The So-Called “Velasco Map”: A Case of Forgery?

Allen, David Y. (ALA Map and Geography Round Table, February 14, 2006)

[more]

[less]

Abstract:

This article examines a well-known map of the northeastern United States and southeastern Canada allegedly made in or around 1610. The map was uncovered in the Spanish Archives at Simancas in 1887. Supposedly, it is a copy of an anonymous English map, which was sent to King Phillip III of Spain by the Spanish ambassador to London, Don Alonzo de Velasco. This article raises the possibility that the map may actually be a nineteenth-century forgery. The map is based primarily on information found on early seventeenth-century maps, most of which were not published in 1610, although it is possible that manuscript copies of these maps might have been available as early as 1610. The overall geographic framework of the map seems to be improbably accurate for its supposed date of creation. The map contains numerous oddities, and many features on the map do not appear on other maps made in the early seventeenth century. Overall it seems anachronistic and it stands in isolation from other maps made around 1600. Although no single feature on the map proves beyond a doubt that it is a forgery, the overall weight of the evidence makes it seem highly probable that it is a fake. Tests on the paper, pigment, and handwriting of the map should be made to prove conclusively whether or not it is a forgery.

Teaching the History of Cartography: A Case for the Marriage of Special Collections and Distance Learning

Kovarsky, Joel (ALA Map and Geography Round Table, September 25, 2006)

[more]

[less]

Abstract:	Very few institutions offer introductory courses in the history of cartography. Distance learning is a way to make this type of course more widely available. This paper discusses the ways in which special collections resources (maps, atlases and related materials) can be used in conjunction with existing distance learning technologies to expand access to educational opportunities in the field. The purpose of this article is to discuss the feasibility of the distance approach, not to provide a detailed example. Expanding access through distance learning would benefit students, life-long learners, librarians, faculty, and other interested individuals. The main emphasis is on blended learning situations, employing both synchronous (real-time) and asynchronous technologies.

Problems That Arise When Providing Geographic Coordinate Information for Cataloged Maps

Gonzalez, Jorge A. (ALA Map and Geography Round Table, October 16, 2007)

[more]

[less]

Abstract:

Maps are not always published with coordinates. However, by following strict guidelines in the 034 and 255 MARC fields, and by using cataloging rules, one can interpolate this data in order to provide coordinates in bibliographic records. Bounding boxes and center point coordinates are key components in the catalog record, but problems arise with maps providing information outside of discussed or established standards, or maps not providing coordinates at all for different reasons. This article explores the importance of correctly understanding, using, and interpreting map cataloging rules to provide the most accurate information possible, with the goal of making it possible to find maps quickly and accurately—whether using database retrieval or a coordinate-driven search engine. It is proposed that we can find an efficient universal method to represent locations, addresses, and areas of the world through the use of geographic coordinates for print and digital cartographic materials. Finally, the article states the strong need to standardize spatial cataloging information to improve search query responses by providing uniform information and by addressing the problems discussed in this article.

An Analysis of Toponymic Homonyms in Gazetteers: Country-Level Duplicate Names in the National Geospatial-Intelligence Agency’s Geographic Names Data Base

Caldwell, Douglas R. (ALA Map and Geography Round Table, August 20, 2008)

[more]

[less]

Abstract:

Place names are the most common way we identify geographic features. When place names are unambiguous, they can georeference features, locating them uniquely on the globe. The problem with place names is that they are often not unique; each place may have many names and many different places may have the same name. This paper studies the issue of identical names which refer to many different places, i.e., toponymic homonyms. Our country level analysis, using the National Geospatial-Intelligence Agency’s Geographic Names Data Base, lays the foundation for future systematic analysis of the toponymic homonym problem. To better understand the scope of the problem, we evaluated the number of toponymic homonyms, toponymic homonyms as a percentage of all names, the maximum number of places referenced per toponymic homonym, and the 90th percentile of thetoponymic homonym count. Finally, we calculated a measure of toponymic homonym complexity.

How to Map a Sandwich: Surfaces, Topological Existence Theorems and the Changing Nature of Modern Thematic Cartography, 1966-1972

Hessler, John (ALA Map and Geography Round Table, March 15, 2009)

[more]

[less]

Abstract:

This paper is meant to be the beginning of a project that examines the use of abstract mathematics and the changing ontology of mapmaking in the early years of the development of computer cartography. The history of the conceptual developments that took place during this revolutionary period in the history of mapmaking is both controversial and incomplete. Much of the primary source material has yet to be examined by historians, residing as it does in obscure journals, government archives and in obsolete software. This study provides a look at one example of this conceptual development in the early years of computer cartography through a close reading of two papers on existence theorems published by the Harvard Laboratory for Computer Graphics and Spatial Analysis. It attempts to highlight the changing conceptual and mathematical foundations of mapmaking during this period and in doing so provides a case study for the difficulties that historians of modern cartography face in researching this critical period in its history.
