Low Altitude Enroute Charts
February 6th, 2010
2 comments
Low Altitude Enroute Charts are used for aircraft navigation below 18,000 feet in the United States. The charts show the locations of radionavigations aids (VORs, etc.), airports, intersections, airways, etc. Unlike Sectional, these charts do not show ground topographic and visual navigation features.
The charts have been merged together to create seamless coverage for the entire lower 48 United States. I hope to add Alaska soon. I probably will not be able to add the Caribbean.
These charts were purchased from the National Aeronautical Charting Office (NACO) and are NOT CURRENT. They are for simulation and entertainment purposes only!!

Haiti Earthquake Maps and Data
January 12th, 2010
18 comments
On Tuesday, January 12, 2010 at 4:53 PM, a 7.0 magnitude earthquake struck near Port-Au-Prince, Haiti. Relief agencies and scientific agencies from all over the world have been compiling maps and other data to aid in relief efforts. Over the last several days I’ve been trying to help compile maps and other GIS data into KML format for Google Earth. I will try to continue to update this web page as more maps and data become available.
If you are simply looking to view maps and other data related to Haiti and the Earthquake, then you should use the Google Earth link below (download and install Google Earth first). This will add numerous map/data layers to Google Earth. Simply check the boxes next to the map/data layer that you want to view and it will become visible. Some of the layers may take a minute or two to load, depending on the speed of your internet connection.
A detailed list of all the layers is included below. Every time you restart Google Earth, any new map/data layers will automatically be added to Google Earth on your computer.
If you are a GIS professional or relief worker, then you might find some additional useful information below, including offline version of the Google Earth KML files, GeoTIFFs of the source maps, and SHP files of the vector data. If you’re not a GIS Professional, then you should probably only use the Google Earth version of the maps/data from above. Pretty much everything listed below is included with the Google Earth version above.
Layers marked with a ** are included as KML in a single zip file that can be downloaded and used offline with Google Earth – Offline KML zip (Version 2)
Update 1/16 – Here is a zip file with 19 layers of data from MINUSTAH in KMZ format for Google Earth. Layers include hospitals, wells, rivers, roads, landmarks, etc, etc. These are not yet included in the main KML link above (ran out of time today). I’ll try to add later tonight. In meantime, you can download the zip file and just load the KMZ files individually.
Update 1/16 – Here is a zip file with 50K topographic maps covering pretty much the entire country of Haiti. The zip file is about 390 megabytes. These are 8-bit GeoTIFFs. I should have KMZs of them all tomorrow.

Washington DC Historic Maps
January 11th, 2010
No comments
This is a collection of historic maps and birds eye images of Washington DC during the late 1800s and early 1900s. The collection includes 58 highly-detailed topographic maps that appear to have been completed in the 1870s and 1880s of the outlying areas of Washington DC. These were a bit tricky to georeference, but they turned out to be amazingly accurate given the time period in which they were originally surveyed. The topographic maps show the locations of buildings, military installations, horse race tracks, etc, as well as general land use.
The birds eye images have been placed in the approximate location of the original artist’s perspective. These are very high resolution images so go ahead and zoom in to see all the detail.
All of the maps and images are about 3-5 megabytes and may take a minute or two to load. The following maps/images are included.
- 58 topographic maps from the 1870s/1880s (from NOAA Historic Maps)
- 1792 plan of Washington DC (from NOAA Historic Maps)
- 1851 map of Washington DC (from David Rumsey Historic Maps)
- 1861 map of Washington DC (from David Rumsey Historic Maps)
- 1871, 1883, 1888, 1916, and 1923 Birds Eye images from various locations around Washington DC (from Library of Congress)

High Altitude Enroute Charts

High Altitude Enroute Charts are used for aircraft navigation above 18,000 feet in the United States.

These charts have been merged together to create seamless coverage for the entire lower 48 United States and Alaska. Unfortunately, it does not look like I will be able to add the Caribbean, as those maps use an unknown projection system (if anyone happens to know how to georeference the Caribbean maps, let me know and I’ll add them).

The Megalithic Portal website has created a collection showing the locations of over 15,000 prehistoric and other ancient sites in Google Earth. The collection is organized by categories, such as ancient caves, temples, burial chambers, etc. More information about these locations can be found a their website.
