World Language Maps
Dr. Stephen Huffman has produced a series of language maps that show the distribution of the world's nearly 7000 ethno-linguistic peoples. The maps show, through colored poloygons, the geographic extent of language homelands. I never realized that there were so many languages and it is very interesting to see how the world is divided into areas of homogeneity (such as the United States) and extreme diversity (such as areas in Africa and Asia).
The maps are important works for the field of language study but they are also important examples of great cartography distributed via the web. In addition to display maps, ArcMap Project files, pdf documents and other GIS data can be downloaded from the site.

Hawaii Images and Maps at PanoramicEarth
Panoramic Earth contains interactive maps linked to panoramic images of cities and travel destinations around the world. The tours run in Java, with an indicator on the map to show where you are, and which direction you are facing as you view the images. Most of the current collection covers European destinations, including a tour of London with over 100 images. The technique has also been applied to entire islands, like Mallorca, and a number of Alpine ski resorts.
Outside of Europe, Hawaii Island is also well featured with another 100+ image tour, providing very comprehensive coverage around the island. Being Hawaii Island, the Volcanoes National Park was not left out. Many of the lava flows and craters within the Park and along Chain of Craters Road can be seen, right down to the coastline where lava was entering the sea at the time.

Mars Topography Images Now on Google Maps
Google has posted an interactive topographic map of Mars that you can use to explore the planet's surface. With it you can zoom and pan the Martian surface to view craters, volcanoes, mountains, plains and canyons. The map also has over 100 features marked with pushpins. Clicking on a pushpin gives you more detailed information to help you learn about the Red Planet.

From NASA is this image of a marine phytoplankton bloom showing as a blue-green swirl off the coast of Argentina. These colors are created by light reflecting from the chlorophyll and other pigments contained within billions of tiny plants (phytoplankton) growing in the surface waters. This bloom is sustained by nutrients brought to the ocean by freshwater rivers carrying agricultural run-off and other nutriends into the ocean.

Google Night Map
Peter Pesti of the Georgia Institute of Technology has created a Google Map that merges a nighttime map of the world with the Google Maps data. The result is an interactive map that allows the user to zoom in on regions of the world and see how they would look from above at night. Cities stand out as patches of bright light. It clearly shows economic and population patterns.

Discovering Mayan Ruins from Space
A team of scientists from NASA and the University of New Hampshire hope to discover Mayan ruins using remote sensing technology. They will be working with the Guatemalan Institute of Anthropology and History along with the Department of Pre-Hispanic Monuments.
Their goal is to use satellite images and data to look for chemical signatures of the Mayan civilization's ancient building materials. NASA’s Airborne Synthetic Aperture Radar, an instrument flown aboard a high-altitude weather plane, can penetrate clouds and forest canopies to survey the earth below.

GIS in K-12 Education
Northwestern University is developing MyWorld, a GIS program specifically designed for interactive learning in middle school through college classrooms. Using this software students can access data bases and plot information atop of their maps. The easy-to-use interface and simple design allow students to begin making maps and exploring data with minimal training. Now students can spend their time visualizing data, composing maps and analyzing geographic patterns.

Maps for Students
The Kentucky Transportation Cabinet had thousands of surplus highway maps when a new version was being printed. Instead of destroying the maps they decided to donate them to schools. This is great but it would be even better if a few lesson plans were distributed with the maps.

How Accurate Are Online Mapping Services?
An article in the Pittsburgh Post Gazette lets citizen speak their mind on the accuracy of online mapping services such as MapQuest, Google Local and Yahoo Local and Maps. These sites are among the top destinations on the internet and a reported 87 percent of internet users have consulted at least one of the online mapping services. Some of those interviewed enjoy the services and report great success but others cite incorrect directions that land users in confusing situations, on incorrect routes and making illegal turns.
