Unfortunately the map doesn’t have any zoom controls or an option to view aerial imagery of the same location before the tornado struck. The map, however, does include a dynamic URL that gives the latitude and longitude of the current view. Therefore, if you want to compare before and after views of the tornado, you can grab the latitude and longitude of a view and paste it into Google Maps.

The aerial view above shows Plaza Towers Elementary School.  Below is the aerial view of the same school on Google Maps, taken before the tornado.

Update: Google Crisis Map now also has the same post-tornado imagery. The Google Crisis Map also includes aerial imagery taken at the end of April, so users can compare the pre and post-tornado imagery on the same map.

The New York Times has also created two evocative custom Street View images
of the devastation caused by the tornado in Moore, Oklahoma – Before and After: 360° Views From Moore.

Each stolperstein is placed in the sidewalk outside the victim’s home. Stolpersteine Online is a Google Map of the memorials that have been erected. The project has created about 35,000 stumbling blocks so far. This is a very small percentage of the total number of victims of the Holocaust, however if you zoom in on any German city on this map you still can’t be overwhelmed by the sheer scale of the Nazis Holocaust.

In each quiz question you are presented with a Street View and then have to answer a question related to the view presented. The questions might ask you to name something seen in the Street View or you could get a more general question about something that happened at the location.

Street View Quiz includes a simple interface that allows users to create their own questions by providing a link to a Street View and submitting the question and answer.

GeoGuessr
is a Street View geography quiz that sets you the challenge of guessing
the locations of a series of random Street View images. Using visual
clues, such as the fauna, landscape and street furniture you have to
place a pin on a global Google Map indicating where you think each
Street View image was taken.

The closer your guess to the actual location then the more points you win.

Locatestreet
is a very similar game that presents a series of random Street Views
and the player has to guess the country where the image was captured.

The featured terrain, architecture, street furniture and modes of transport
all provide clues that can help the player guess the country of origin
of the random Street View image. The game also includes three clues for
each image, but be warned – if you use a clue you will win less points.

The custom Street Views were captured on Tuesday and have been synced with the Google Maps Street Views that were captured in December 2007. If you pan either Street View both the before and after image moves so you can compare the images around the whole 360 degrees.

The Times captured two custom Street View images, one at South Avery Drive, between Southeast 4th and 8th Street, and the other at Southeast 4th Street and Heatherwood Drive.

Geomask allows you to simply draw around an area on Google Maps and just press a button to generate the polygon to create this neat masking effect. You aren’t even restricted to one area and you can highlight as many areas as you want on the map.

The tool is really easy to use. I created a polygon mask to highlight the London Olympic Park and then created a map with the mask in under two minutes using Geomask (you can see the result in the screenshot at the top of the post).

Using a polygon mask is a very effective way to highlight a specific area on a Google Map. Here are a couple of Google Maps applications that have used a similar polygon masking effect to highlight regions on the map.

Der Bayerischer Wald is a great Google Maps guide to hiking routes, accommodation and events in the Bavarian Forest region in Germany.

Ourense en Verde is using the Google Maps API to map the natural beauty of the Ourense region in Galicia, Spain.

Currently the Street Food App can help you find nearby food trucks in Boston, Calgary, Edmonton, Halifax, Ottawa, Toronto, Vancouver, Columbus and Victoria. Each city includes an option to view the current location of the food trucks on a Google Map.

Each truck is displayed on the map with a green or red map marker, green markers indicate the trucks currently open for businesses and the red markers indicate that they are currently closed. Users can click on each food truck on the map to view a small review and the truck’s hours of business.

Today Google has added 20 more museums, 1,500 new high-resolution artworks and 16 Gigapixel images to the project. The Gigapixel images include “The Scream” by Edvard Munch. The new museums include the Fondation Beyeler Museum in Switzerland and the Monastery of St. John the Theologian on the Greek island of Patmos

onformative has created a computer program, called GoogleFaces, that scans Google Maps satellite imagery looking for patterns that humans might believe are human faces. GoogleFaces scans through one satellite image after another on Google Maps, sequentially along the latitude and longitude of the globe. After scanning around the world it then switches to the next zoom level and starts all over again.

As it scans each satellite imagery the GoogleFaces face detection algorithm records the latitude and longitude of any ‘faces’ it finds. The onformative website has a few examples of the faces already found on Google Maps, including the one above, found in the satellite imagery of Russia.

The map includes options to filter the companies displayed on the map by location and by sector. The map is primarily focused on the San Francisco Bay Area but the developers say that they have plans to expand the site to include other tech hubs such as New York, Los Angeles and Boston.

Made in NI is a Google Map of Northern Ireland’s start-up’s, tech companies and co-working spaces.

Tech maps for individual cities are now being created for many locations around the world. However we don’t often see attempts to map entire countries / provinces. Made in NI is a nice attempt to map all of Northern Ireland’s burgeoning technology companies.

As well as mapping individual companies, Made in NI also maps wi-fi spots, code clubs and learning spaces.

The app analyses the language patterns found in Texas newspapers from 1829-2008. Using a timeline slider tool you can select any date range and, using the map, you can select from a number of locations in Texas. The results of each search are then displayed below the map.

The results show the most common words (word counts), named entities (people, places, etc), and highly correlated words (topic models). The results can be viewed in list view or you can view the results as a word cloud.
