ASPRS Board votes unanimously for immediate funding to continue national moderate resolution imaging programMonday, February 13th, 2012Recently the American Society for Photogrammetry and Remote Sensing (ASPRS) Board of Directors voted unanimously for a third resolution calling for immediate support and funding for the continuation of the Nation’s moderate resolution imaging program. Several events have led to the possible discontinuation of the collection of moderate resolution, multispectral remote sensing. One of those events was the technical failure in the Enhanced Thematic Mapper Plus (ETM+) instrument on-board the Landsat 7 spacecraft in May 2003, and most recently the decline of the Landsat 5 spacecraft. Although many other remote sensing efforts exist these days, the more than 40 years of uninterrupted Landsat imagery has been instrumental in monitoring ongoing stresses on the Earth from climate change, population, land use and other factors that challenge the natural resources available to mankind. According to the announcement, measuring the Earth’s resources such as food, water, and energy is best done by collecting and implementing moderate resolution imagery. GeoEye publishes images of the Sahara Desert, Eastern AlgeriaFriday, February 10th, 2012In GeoEye’s gallery are numerous high resolution images of locations across the globe. The Eastern Algerian portion of the Sahara is an otherworldly place, a region of great diversity with endless stretches of sand dunes and rocky platforms that can reach more than 2,000 meters. The Tassili n’Ajjer “Plateau of the Rivers” National Park is a vast plateau in southeast Algeria at the borders of Libya, Niger, and Mali, covering 72,000 square kilometers. Satellite Image Courtesy of GeoEye Video of Mount Etna shows violent volcanic burstsFriday, February 10th, 2012Sicily’s Mount Etna is the largest active volcano in Europe and the most well-known. Yesterday it burst forth with quite a fireworks display overnight. John Snow’s 1854 Cholera Map comes to life with the CartoDB platformThursday, February 9th, 2012John 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. Satellite imagery in Colorado may face steep federal budget cutsWednesday, February 8th, 2012The 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. Combined, the companies have about 1,200 employees. This satellite image made available Sept. 26, 2009, by DigitalGlobe shows the suspected Iranian nuclear facility of Fordo near the holy Shiite city of Qom, where Iran is has begun enriching uranium, according to the U.N. atomic watchdog group, the International Atomic Energy Agency.

LiveLink integrates GIS with remote sensing and image processingTuesday, February 7th, 2012Mladen Stojic, vice president Geospatial, Intergraph, talked about their new Live Link product which integrates Intergraph GeoMedia objects into ERDAS IMAGINE. Intergraph is a wholly owned subsidiary of Hexagon acquired in 2011. What this product offers is what customers have been asking for – an integrated approach to desktop workflows, combining the desktop GIS capability of GeoMedia integrated with the raster remote sensing and image processing capabilities of ERDAS IMAGINE. How to measure the world’s largest citiesFriday, February 3rd, 2012Scholars 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”. Saving changes to your default raster type [ArcGIS Resource Center]Thursday, February 2nd, 2012For 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. |
