Car chase in Google Maps

For a little fun, watch this animated car chase short video which uses  imagery pulled from Google Earth (the description of the video says  Google Maps but clearly the opening zoom from the world down to the  streets of Manhattan is pure Google Earth).  The video was created by Honest which is the directing team of  Jonathan Milott and Cary Murnion.  The video is a very short (just over  one minute) excursion through the busy streets of New York with  periodic car crashes and tread marks burned into the pavement. Hope you like it! :)

World’s Highest Resolution Pictures [ I ]

Angel Stadium in Anaheim, California.

Angel Stadium of Anaheim (originally Anaheim Stadium and later Edison International Field of Anaheim) is a modern-style ballpark located in Anaheim, California. It is the home ballpark to Major League Baseball's Los Angeles Angels of Anaheim of the American League, and was previously home to the NFL's Los Angeles Rams (now St. Louis Rams). The stadium is often referred to by its unofficial nickname The Big A.


Machu Picchu, Peru

Machu Picchu is a pre-Columbian Inca site located 2,430 metres (8,000 ft) above sea level. It is situated on a mountain ridge above the Urubamba Valley in Peru, which is 80 kilometres (50 mi) northwest of Cuzco and through which the Urubamba River flows. Most archaeologists believe that Machu Picchu was built as an estate for the Inca emperor Pachacuti (1438-1472). Often referred to as "The Lost City of the Incas", it is perhaps the most familiar icon of the Inca World. Collected September 8, 2003.

Haiti Earthquake Free Maps and Related Resources

Maps, Web Maps, Open Source and related geospatial data and information related to the 2010 earthquake in Haiti

Haiti Earthquake GeoEye Satellite Maps on Google Earth - Working with satellite imaging company GeoEye, Google on Wednesday evening updated its imagery of Haiti to reflect the devastation of 12 Tuesday's earthquake.

DigitalGlobe - Haiti Coverage map (pdf)

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA’s Terra spacecraft captured this false-color image of Haiti on January 21, 2010, nine days after a magnitude 7.0 earthquake struck the region and caused massive damage and loss of life, and one day after a large 5.9 aftershock caused additional damage.

While ASTER’s 15-meter (50-foot) resolution is not sufficient to see damaged buildings, it can be used to identify other results of the shaking. Tiny dots of white against the plant-covered landscape (red in this image) are possible landslides, a common occurrence in mountainous terrain after large earthquakes. The possible landslides were identified by carefully comparing the new image with an image acquired one year ago.

Port-au-Prince, Haiti’s capital, is silver in the false-color image. The rivers are pale blue, while the ocean is dark blue. Exposed soil is white. See the picture here

New York - 1924-2008 - City Map Airphotos

CITY MAP - NEW YORK - AIRPHOTOS

History can be viewed in many ways, but man I’m I excited about this. I feel like I just found a time machine. NYC.gov has recently launched a Google-esque interactive aerial map of New York in 1924! I have now spent many hours obsessively traveling (virtually) all over the city to see how its changed. I’ve compiled some of my findings here to save everyone some time. Among other things you’ll see that the city was still sans airports in 1924, that there used to be another huge reservoir in Central Park, that the waterfront was much busier back then and that the city is much greener now than it used to be. This is a before and after history of New York City told by comparing aerial photography from 1924 and 2008. Much has changed in 84 years, and much has stayed the same. Here are some examples and observations.

All images are from NYC.gov. They were originally taken by Arthur S. Tuttle, Chief Engineer, Board of Estimate and Apportionment, who flew over the city in 1924 to document all of its landmarks.

You can navigate the map for yourself here

Click on the images below to enlarge.

WTC Site

The original World Trade Center complex was built from 1966 -1973. Battery Park City, an addition to Manhattan’s west side, was built where piers used to stand using landfill from the WTC construction.


Polo Grounds and Yankee Stadium

Yankee Stadium (lower right) was only one year old in 1924. The stadium seen at the upper left is the Polo Grounds, home to the New York Giants (now in San Francisco). The Polo Grounds originally opened in 1890 and had just been renovated in 1923. It was demolished in 1964.

East River Bridges

The waterfront around the Brooklyn and Manhattan Bridges was crowded with ships in 1924.

Union Square

Union Square, one of the greatest public spaces in the world, was laid out in 1832 and rebuilt in 1882. It was looking pretty bare in 1924.

Columbus Circle

Columbus Circle has acquired more more circle-ness and vegetation.

Penn Station & MSG

The cathedral that was Penn Station was only 14 years old in 1924. It was demolished in 1963 and shoved underground to make way for Madison Square Garden.

Stuyvesant Town

Stuyvesant Town was a Robert Moses era project built in the mid 1940s. Its of the most iconic and successful of post-war private housing communities and was occupied mostly by WWII veterans’ families.

From wikipedia:
Before the construction of Stuyvesant Town, the neighborhood contained eighteen typical city blocks, with public schools, churches, factories, private homes, apartments, small businesses, and even relatively new modern-style apartment buildings. In all, 600 buildings, containing 3,100 families, 500 stores and small factories, three churches, three schools, and two theaters, were razed. As would be repeated in later urban renewal projects, some 11,000 persons were forced to move from the neighborhood. In 1945, The New York Times called the move from the site "the greatest and most significant mass movement of families in New York’s history" (NYT, March 3, 1945). The last residents of the Gashouse District, the Delman Family, moved out in May 1946, allowing demolition to be soon concluded.

Empire State Building

The Empire State Building was still 5 years away. Buildings were still standing on its future site in 1924.

JFK Airport

Built between 1943 and 1948 to relieve La Guardia’s traffic, JFK Airport was originally known as Idlewild after the Idlewild Golf Course it replaced

La Guardia Airport

La Guardia Airport was built on fairgrounds previously used by the Gala Amusement Park. It originally opened as a private flying field named Glenn H. Curtiss Airport. It was later named North Beach Airport before being turned into a commercial airport and named New York Municipal Airport in 1939. It was renamed La Guardia, after the NYC mayor that championed it, in 1947.

Coney Island

Coney Island picked up some new sand. The Cyclone roller coaster (on the right side of the 2008 picture, was built in 1927. There’s another roller coaster standing in its place in 1924. The iconic red Parachute Jump structure seen below the baseball stadium in the 2008 image, was not built until the 1939 New York World’s Fair.

Bryant Park

Bryant Park, originally built as Reservoir Square in 1847. The park has suffered many ups and downs throughout its history. In 1878, the new Sixth Avenue Elevated railway cast a shadow on the park, leading to neglect until the 1930s. It was redesigned in 1933 as a Great Depression public works project under Robert Moses, but again neglected after the El was taken down and construction began on the Sixth Ave Subway line. By the 70s, the park, the known as Needle Park was a haven for drug dealers, prostitutes and the homeless. The park was cleaned up through the 80s and redesigned completely in 1988. As you can see its looking a little better now then in 1924.

Central Park and the Met

Central Park’s Great Lawn used to be a the Lower Reservoir. As the Croton-Catskill Reservoir system was completed, to satisfy New York City’s need for water, the Lower Reservoir came to be redundant. It started getting drained in 1930. It became a “Hooverville” of improvised shacks as it stood idle before being completed as the Great Lawn during La Guardia’s mayoral administration in 1936. The Metropolitan Museum, founded in 1870 and moved to its Central Park location in 1880, is the large structure seen in the park in the middle of the image.

Prospect Park

Prospect Park, designed by Frederick Law Olmsted and Calvert Vaux of Central Park (and many others) fame, opened in 1867. Its only 57 years old in this picture.

Gowanus Canal

These are Hyperakt’s stomping grounds. The studio is located just a few blocks from the Gowanus Canal, a commercial waterway completed in 1869.

From wikipedia:
After World War I, with six million annual tons of cargo produced and trafficked though the waterway, the Gowanus Canal became the nation’s busiest commercial canal, and arguably the most polluted. The heavy sewage flow into the canal required regular dredging to keep the waters navigable.

Factories, warehouses, tanneries, coal stores, and manufactured gas refineries sprang up as a result of its construction. Much of the brownstone quarried in New Jersey and the upper Hudson was placed on barges with lumber and brick and shipped through the canal to build the neighborhoods of Carroll Gardens, Cobble Hill, and Park Slope.

West Side Railyards

The west side rail yards in Manhattan.

Brooklyn Museum

The Brooklyn Museum
, designed by McKim, Mead, and White, opened its doors in 1897. The museum was originally intended to be about 4 times bigger, but funding for construction dried up.

Central Park Lake

Some things haven’t changed much. The Central Park Lake has always been filled with boaters.

Ebbets Field

The Brooklyn Dodgers played at Ebbets Field, located just northeast of Prospect Park in Brooklyn. It opened in 1913 so it was just 11 years old here. The stadium was demolished in 1960 after the Dodgers moved to Los Angeles in 1957. It was replaced by a housing project.

Flushing Meadows Park

Flushing Meadows
was another Robert Moses pet project. It was a massive dumping ground in 1924. It was developed in the 1930s to house the 1939/40 New York World’s Fair and later also housed the 1964/65 New York World’s Fair. The blue circle in the map on the right is the Unisphere, the centerpiece icon of the latter World’s Fair. The Unisphere is a 12-story high, spherical stainless steel representation of the Earth.

Grand Army Plaza

The glorious Grand Army Plaza is at the northwest corner of Prospect Park. It was designed by Frederick Law Olmsted and Calvert Vaux in 1867. Brooklyn had some serious Paris envy.

Sheep Meadow

Central Park’s Sheep Meadow
.

Sara Roosevelt Park

Sara Roosevelt Park
at Houston and 2nd Ave was built in 1934, 10 years after this picture. Check out the elevated subway on the Bowery.

Manhattan & Brooklyn

Manhattan, Brooklyn and Queens.

Central Park

Central Park
was opened in 1859, completed in 1873. The park was designed by the famous landscape architect Frederick Law Olmsted and the architect Calvert Vaux.

European Digital Archive of Soil Maps - EuDASM

European GLOBAL Digital Archive on Soil Maps


For some 40 years, ISRIC – World Soil Information has been providing significant support to the international science community by collecting and archiving regional, national and global-scale maps of soils and land resources.

Realizing the need to conserve the information on existing maps, which underpin the fast-developing thematic mapping strategies to support soil protection, the Institute of Environment and Sustainability (IES) in the European Commission and ISRIC came up with this project and the immediate objective is to transfer soil information into digital format, with the maximum resolution possible, to preserve the information of paper maps that are vulnerable to deterioration.

Beyond data rescue, the archive is expected to develop into a common platform for storing soil maps from around the world and making the information readily accessible. Organizations that maintain soil map archives in paper form, and wishing to conserve this information by transferring it into digital form, are invited to join the EuDASM program.

A Sample Soil map of Europe:

A Sample Soil map of Asia:

The initiative for this program was taken by Dr Luca Montanarella of the European Joint Research Centre and Dr Otto Spaargaren of ISRIC – World Soil Information in October 2004. The first level success for this initiative was figured out by completion of the around 2000 soil maps pertaining to the African continent. Through this digitization program the map quality and precision of information were preserved against further loss assuming to be required for future use by land resources specialists.


All the maps are categorized, and can be downloaded as below:
  • Africa
  • Asia
  • Canada
  • Caribbean islands
  • Europe
  • Latin America
  • United States of America
