December 5, 2011 Data Appeal: 3D Visualization of GIS DataDataDataAppeal is data visualization service that takes GIS data one step further with 3D visualizations. The underlying premise of DataAppeal is the use of more artistic design to represent point geospatial data. Instead of flat 2D layers, the data is symoblized using a 3D and animated data visualization tool (EarthAppealTM). DataAppeal’s Nadia Amoroso explains: DataAppeal ... read more December 1, 2011GIS File FormatsDataThere are well over 100 GIS, CAD and Remote Sensing applications on the market. Listed here are some of the more common file formats along with associated file extension (the last 3 charcters after the period in the file name). File formats are categorized as vector, raster, imagery, and legacy GIS file formats. Vector File Format ... read more  Fabric Engine: 3D LiDAR Rendering Via Web BrowsersDataFabric Engine enables developers to create compute-intensive web applications with comparable performance to native, multi-threaded applications. Fabric Engine achieves this by tapping into all of the processing power of the user’s computer – something that normal web-based applications cannot do. For the GIS market, this means that any web programmer can develop solutions for visualizing ... read more November 30, 2011 New Global Elevation Data Available to Download: Global Multi-resolution Terrain Elevation Data 2010DataThe U.S. Geological Survey (USGS) and the National Geospatial-Intelligence Agency (NGA) have released an updated and more accurate global elevation model that pulls data from Digital Terrain Elevation Data (DTED®) from the Shuttle Radar Topography Mission (SRTM); Canadian elevation data; SPOT 5 Reference 3D data; data from NASA’s Ice, Cloud, and land Elevation Satellite (ICESat); and ... read more November 25, 2011Geosk: GIS Data as a Service (Daas)DataWhats is Geosk and what does it mean for GIS data delivery? Scott Robinson, Director, Global Data Products at Pitney Bowes Business Insight, explains what Geosk means for GIS Data as a Service (DaaS) and how cloud computing can be used to delivery GIS data online. read more...November 6, 2011 GIS Data: A Look at Accuracy, Precision, and Types of ErrorsDataThere is no such thing as the perfect GIS data. It is a fact in any science, and cartography is no exception. However, the imperfection of data and its effects on GIS analysis had not been considered in great detail until recent years. In the last decade, GIS specialists started to accept that error, inaccuracy, ... read more October 23, 2011 Updated 3D Global Topo Data from NASADataBased on measurements from NASA’s Terra spacecraft, a new 3D topographic map has been released as a joint effort by NASA and Japan. The digital elevation model (DEM) was developed from imagery obtained from the Japanese Advanced Spaceborne Thermal Emission and Reflection Radiometer, or ASTER, instrument aboard Terra. ASTER is one of five Earth-observing instruments launched Dec. 18, ... read more October 17, 2011 CryoSat-2Data, Remote SensingCryoSat-2 is the satellite launched by the European Space Agency on April 8, 2010 to collect data in order to understand the relationship between the world’s ice layers and climate change. The satellite collects data about ice thickness over both land and water to analyze the changes in polar ice coverage. The three year mission ... read more October 13, 2011 Detecting Surface ChangeData, Remote SensingInterferometric Synthetic Aperture Radar (also known as InSAR) uses remote sensing techniques to compare two or more synthetic aperture radar (SAR) images in order to detect changes in the earth’s surface over time as small as a few millimeters. The combined image analysis is represented by a color ramping indicating the differences in surface heights between the ... read more October 1, 2011 New EPA Map – Enforcement and Compliance History Online (ECHO) DatabaseDataThe Environmental Protection Agency has released a new online mapping application that maps out all EPA and state enforcement actions for air, waste, and water programs covering the years 2009-2011 as part of the agency’s Enforcement and Compliance History Online (ECHO) database. Data on the map is updated monthly and covers 800,000 facilities across the United ... read more |
