| January 4, 2012 Ice Mapping AppMobile GIS, Remote SensingThe European Space Agency has released a new iOS app for accessing ice data from the ESA’s CryoSat mission. Cryosat-2 was launched in April of last year to collect data to further understanding of the relationship between the world’s ice coverage and climate change. Data collected from the satellite includes ice thickness and changes in ... read more November 17, 2011 Earth from Space Web TVRemote SensingIf you love armchair geographic travels, the there is a new weekly program for you to watch. The European Space Agency (ESA) has launched a web TV program to showcase satellite imagery from its various earth observation satellites such as Envisat and ERS. New installments are shown every Friday at 10 CET. The very first ... read more November 6, 2011 Using Unmanned Aerial Systems (UAS) for Remote Sensing of Archaeological SitesIndustry and Subjects in GIS, Remote SensingUnmanned vehicles are becoming more widely available both in the military and civilian sectors for their usefulness for remotely acquiring a variety of data. Unmanned Aerial Systems (UAS), previously referred to as Unmanned Aerial Vehicles (UAV), are integrated ground, air, and data systems in which an aircraft (fixed wing or rotary) are either remotely piloted ... read more October 27, 2011 Understanding the Earth’s Gravity with ESA’s Swarm SatellitesRemote SensingThe European Space Agency will be launching three satellites next year with the objective of studying the earth’s gravity. The three identical satelittes will be launched on a Rockot launcher from Plesetsk in northern Russia and are currently undergoing testing at IABG in Ottobrunn, Germany. Once launched, the Earth Explorer Swarm mission will be used to help ... 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 September 29, 2011 Urban Heat Island AnalysisFeatures, Remote SensingRemote sensing methods are being used to monitor thermal radiation in European cities. Hardscape surfaces such as roof tops and concrete pavement absorb solar radiation during the day and retain that heat longer than softscape surfaces such as vegetation. This phenomenon is known as an urban heat island and the contrast can most notably be ... read more September 20, 2011 Remote Sensing Organic CropsIndustry and Subjects in GIS, Remote SensingThe variations in crops grown organically versus conventionally are significant enough to be detected by analysis on satellite imagery. The European Space Agency (ESA) has been working with Ecocert, an organic certification organization, as well as consulting firms Keyobs and VISTA, and Belgium’s University of Liège, to develop a methodology to analyze satellite imagery to differentiate crop fields ... read more July 9, 2009LiDAR ResourcesData, Link Library, Remote SensingFind resources, tutorials and tools for working with LIDAR (Light Detection and Ranging) elevation data, particularly within the GIS environment. LAStools Tools page from Martin Isenburg and Jonathan Shewchuk for converting, viewing, and compressing LIDAR data in LAS format. LIDAR Data from NOAA Use this page to see if LIDAR data is available for download from NOAA within ... read more May 26, 2008 Object Oriented Image Analysis For Urban Development and ManagementFeatures, Industry and Subjects in GIS, Remote SensingThe research topic is land cover mapping with object oriented image analysis approach. The research took urban conglomeration of Vijayawada city as one of the case study. Over the last 30 years remote sensing methods have operationally been used for environmental issues, especially in areas where only insufficient field data are available for urban development ... read more |
