John Snow created a map of a cholera outbreak in the district of Soho, London in 1854, which helped to convince authorities that the disease was caused by water ( in particular, it originated from one pump in Broad Street). The CartoDB platform allows you to map data and develop location aware applications very easily. This example of John Snow’s Cholera Map of London presented with CartoDB demonstrates how CartoDB can quickly combine different data types, then display them on a map.

The Denver area has become a center of satellite imagery providers in recent years. Proposed steep cuts in the U.S. Department of Defense budget could affect satellite-imagery providers DigitalGlobe, headquartered in Longmont, and GeoEye,based in Virginia with a processing and operations center in Thornton.

Scholars are having trouble measuring the world’s largest cities – largely because the terms the cities are measured by differ from place to place. They have come up with a total of 30 largest cities in the world.
Richard Greene, associate professor of geography at Northern Illinois University in the United States, says even the most authoritative list, from the UN, “compares apples with pears”.
For those who have made any changes to the default raster type, you will probably want to save your changes. This way you can re-use your custom raster type if you want to load additional raster data with the same properties and functions.

In 2012, utilities will begin to invest heavily in analytics in order to manage increasingly large volumes of data due to the rise of smart meters. Utilities and GIS companies are also exploring how this information can be used for real-time tracking and operations and to help drive business value.
Smart buildings will become important to utilities. Twenty-five states have energy-efficiency standards or targets and smart buildings can help meet these goals. The building energy analytics market will double between 2012 and 2015, jumping from $193 billion to $402 billion.

For about three years, I have been watching Autodesk do interesting things with their GIS division, finally rolling some great mapping products into their Infrastructure Division.
