Joining the 5 maps together digitally enables a much better understanding of the importance of the work. The 44 United States Air Force and NASA separate maps of the moon are below.Īn interactive three dimensional globe has been created from the 44 georeferenced moon map images.Ĭlarence King and his 40th Parallel Survey of 1876 made 5 maps showing a broad cross section of the American West, something not attempted before. Then the joined images can be reprojected as below into a single orthographic projection.

All 44 maps in the series were joined using GIS to georeference them in their native projections, Lambert Conformal for the top and bottom 3 rows and Mercator for the 2 middle rows north and south of the equator. The United States Air Force and NASA produced 44 maps of the moon in the early 1960's that combined earth-based telescope observations with existing photographs, adding lunar features artistically drawn and airbrushed with India ink. This composite map below shows all 50 cities at the same scale in one image.īelow are the separate images of the 50 cities that are not able to show relative size because of the digital display system - digital images tend to all look the same size. It gives a much better picture of Haussmann's changes than the separate maps do by themselves.Īrchitect and data visualizer Richard Saul Wurman in 1963 created with his students a book - The City, Form and Intent - with images that enable comparison of 50 cities in different parts of the world at the same scale, 1:14,400. This new map image joins all 16 separate sheets of Paris to show the entire city as one map. Here the 16 Flinders Australia charts are joined and overlaid on the general chart to show how all the charts fit together.īaron Haussmann published these 16 separate maps of Paris in 1868 to show his proposed new boulevards that would transform Paris into a modern metropolis. Matthew Flinders' 16 charts published in 1814 were among the first to map the coast line of Australia. The joined sheets give a complete view of the Nile and its huge delta.ĭetail of the Atlas of Egypt sheets showing the original Nile river course underneath Lake Nasser.
The 165 separate sheets of the 1914 Atlas of EgyptĪll 165 sheets of the Atlas of Egypt joined. We combined all 165 sheets, georeferenced them, and overlaid them on modern maps below to show changes. The 1914 Atlas of Egypt shows the entire Nile River in 165 sheets at a large scale of 1:50,000. To date we have created 1,674 interpretive composite maps, views, and texts as well as over 56,000 georeferenced maps.Ĭlick on any of the images below to view the interactive online version. Below are some examples of these interpretive maps that we have created over the past 20 years. To do this, we create composite maps, georeferenced maps, composite views, interactive globes, composite texts and other types of digital versions that expand map interpretation and enhance use. But we also create the potential to repurpose these copies to advance understanding of the original maps.
When we digitize historical maps we create copies that can be shared and used by all. More Than Digital Copies: Maps That Interpret Maps
