Libya Maps

 

Although Libyan law stipulates that Sahara travellers must be accompanied by a local desert expert, one still needs to use specialist maps and GPS devices, as none of the local experts knows all (or even a fraction) of the locations of the various sites of interest in the Sahara. In fact, even the best map in the market only features a rough guide to the locations of a tiny selection of the hundreds of thousands of cave drawings and rock engravings scattered across the desert; and therefore complete maps of the Sahara are yet to appear.  

 

These pages will attempt to collect information, resources, links and maps relating to Libya and the Sahara. There are a number of GPS websites currently attempting to build a global database of GPS coordinates, based on public contributions. Our current collection so far includes a number of maps originally produced by the US Army Map Service and used here courtesy of the University of Texas Libraries at Austin; which although are not as detailed as, say, EWP's Jabel Acacus Map, they still nonetheless show the main features of the landscape, tracks and (of particular importance) the old local names, some of which have now disappeared from memory. They also cover a large area of Libya.

 

We have also customised a number of Google maps to allow a number of tools including distance calculator (which measures distance between any two points on the planet); coordinates finder (which gives the coordinates of any place on earth simply by one click); and Panoramio photos from all over Libya. Google maps are very easy to use and have been used worldwide to discover a number of new features, craters and sites. We have also linked to the interactive Gazetteer database by the American National Geospatial-Intelligence

 

 

 

 

What is a topographic map?

 

Topographic maps show the shape and the main features of the land. The topography of any given area is shown by contours or brown lines representing different elevations:

  1. thick brown lines (Index Contours) define the actual feature and give its height.
  2. thin brown lines (Interval Contour) give the variation in elevation: very close lines mean steep slopes, lines with large gaps indicate gradual slopes.

What is scale?

It is the ratio representing the relation between a distance on a map and its corresponding distance on the land. For instances, a scale of 1:100,000 means that 1 unit on the map is equal to 100,000 identical units on the land. Use the link to Scale Calculator (see below) to find the actual value of any scale unit.

 

 

 

Map Scale Calculator:

Scale Calculator: beg.utexas.edu/GIS/tools/scale2.htm

 

Using the tool available at the above link, you can calculate the actual value of any scale unit by typing only the representative fraction of your map: for example: if the map scale is 1:100,000, enter 100000 in the box provided.

Examples:

 

Representative = Value in inches

1000 = 0.015  miles per inch
5,000= 0.078  miles per inch
10,000= 0.157  miles per inch
15,000= 0.236  miles per inch
25,000= 0.394  miles per inch
50,000= 0.789  miles per inch
100,000= 1.578  miles per inch
125,000= 1.972  miles per inch
150,000= 2.367  miles per inch
175,000= 2.761  miles per inch
200,000= 3.156  miles per inch
500,000= 7.891  miles per inch
1,000,000= 15.78  miles per inch
1250,000= 19.72  miles per inch
1,500,000= 23.67  miles per inch
1,750,000= 27.61  miles per inch
2,000,000= 31.56  miles per inch
2,250,000= 35.51  miles per inch
2,500,000= 39.45  miles per inch
2,750,000= 43.40  miles per inch
3,000,000= 47.34  miles per inch

The term geospatial intelligence implies collecting information via mapping, charting and geodesy, and then evaluating the data to describe the actual physical features and their geographically-related activities on the ground. A Gazetteer is a database or a list of geographic place names and their longitudes and latitudes. The above link leads to an interactive database on which you can click the desired location to display its coordinates and find its local name(s). The geonames features will be displayed only when the scale is approximately 1: 2,000,000 or larger, so if names do not appear, just keep

 

 

 

 

The World of The Landsat Satellites & Their View of The Earth

 

The Landsat's mission is to collect, archive, and distribute data of all the Earth's land surface.
zulu.ssc.nasa.gov/mrsid/mrsid.pl

 

The first Landsat was launched on July 23, 1972, to initiate a new era of Earth observation from space for non-military purposes. The information collected  is now the standard for Earth observations. Landsat circa 1990/2000: click on the map to zoom in/out, or 'Select Image' from the menu below the map and click on the desired region on the map to display the image in a new window.

NASA's World Wind

 

Download World Wind For Free, directly from worldwind.arc.nasa.gov/

 

NASA's open-source-program World Wind is similar to Google Earth - except in that it is free -   very handy indeed if you just want to publish an actual image in your website, rather than having to link to it via embeded script. The Landsat Global Mosaic (except for i-3 visible layer), Blue Marble, and the USGS raster maps and images are all Public Domain. (Please note that not all data provided by the add-ons is Public Domain). The downloded program includes the required: .NET runtime, and the managed DirectX library. For download: worldwind.arc.nasa.gov/ ;  for user manual: learn.arc.nasa.gov/worldwind/ .
