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.

Download With Google Earth

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.

Updated 11/2009

This collection contains 28 1×2 degree geologic maps covering the entire state of California.

The 1:250,000 scale maps were produced in the 1960s and 1970s by the USGS and State of California Division of Mines and Geology.

TerraLook Archive

November 27th, 2009 No comments

The TerraLook Archive contains 1,000’s of satellite images from the Terra and Landsat satellites. Many of the images covering environmentally sensitive areas (South American rainforests, etc.) throughout the Earth have been converted for viewing in Google Earth by Dr. Mark Mulligan of King’s College London.  The images in this collection date from 1972 to 2006.

Simply select the year you are interested in and zoom into one of the areas covered with imagery. The imagery should appear automatically.

USGS Topographic Map Update

November 15th, 2009 1 comment

Looks like a lot of people are using the Google Earth USGS Topographic maps.  Couple updates that I thought I’d pass on.

First of all, I recompiled the index to be much easier to use.  You no longer have to navigate through two index levels.  Now, simply zoom down and the index will appear automatically as you navigate around the US.  Click on one of the map outlines to open up a window with a button to download the map.

At the same time, the new index fixes a major bug that prevented many maps from loading.  You should now be able to view all of the maps south of 48 latitude.  If you find one that doesn’t work, please let me know so I can fix it.  I hope to have the remaining maps north of 47 latitude done by next month.  When done, this collection will have about 55,000 maps (~150 gigabytes) available to view in Google Earth.  I’m also going to try to add Alaska.

Several people have asked about Canadian Topo Maps.  I have been downloading them and I could add them to the collection.  But I think those will be another 200-300 gigabytes, and I don’t want to push my luck with my web host.  So that project is on hold until I figure out a way to host them.  If you happen to have a 200-300 gigabytes of server space laying around and want to help out please contact me.

I have also added some instructions on the Google Earth USGS Topographic maps page to show you how these topographic maps can very easily be embedded on your own web page or blog using the Google Earth Browser Plugin.

Lastly, I am still working on my Historic Topographic Map collection.  I know there are some maps in that collection that are broken.  The update I’m working on will fix those and probably double or triple the number of historic topo maps in the collection.  Sorry, but no time frame on when that will roll out.  The historic maps are a lot more work than the current maps.

How to Research Historical Aerial Photographs

August 25th, 2009 No comments

Although this isn’t directly related to Google Earth, I thought there might be some people interested in researching old aerial photographs that aren’t available in Google Earth.  I’ve put together some instructions on how to do this research yourself.

We will be using the EarthExplorer website created by the USGS, which has  historical aerial photographs covering most of the continental US that often date back to the 1940s or 1950s.  These aerials are available to download at no charge.
