Multi-temporal Satellite Imagery

Taiwan lies at the border of the Eurasian and Philippine Sea Plates and faces the Pacific Ocean. Earthquakes and typhoons are the two main threats, and can cause landslides, debris flow, flooding and other natural hazards. In 2005 the World Bank categorised Taiwan as the most vulnerable country in the world in terms of the percentage of exposed areas and multiplicity of disasters. Given these circumstances, planning for hazard mitigation is important, as is management for hazardous conditions. Also necessary are decision-support tools for understanding firstly where disaster is likely to occur, secondly, when, and thirdly what kinds of disasters... (read more)

Satellite Imagery for Mapping

The ICA Commission on Mapping from Satellite Imagery is responsible for educating and informing the geospatial- data handling community about the link between the raw data captured from satellite imagery and the extraction, presentation and application of information derived from such data. See previous report on this page, GIM March 2007. ToR The Terms of Reference of the 2007-2011 commission, approved at the Moscow ICC, August 2007, include fundamental work: “[…] analysis of existing and forthcoming satellite imagery in view of their potential inputs for producing and updating topographic and thematic maps and databases; and assessment of the cartographic capabilities...

Mapping from Satellite Imagery

The emergence of new, low-cost, internet-based mapping tools like Google Earth, Google Maps, and NASA World Wind that make thousands of satellite images available to a wide audience has greatly influenced perception and awareness. This goes for both the general public and the scientific community, who now see the enormous potential of mapping from satellite imagery. Such tools highlight the crucial role of remote sensing in providing fast, up-to-date cartographic information for informed decision making, particularly for rapid mapping of pre- and post-disaster events, emergency planning, geomarketing, or even simpler activities like planning a holiday trip. The ICA Commission on... (read more)

Satellite Imagery of Israel's Fires

A satellite map of the Israeli disaster area was used by Emercom of Russia during their assistance in fire-fighting activities near Haifa city. Detailed imagery of IKONOS satellite from 4th December was used by ScanEx specialists to prepare and provide a satellite map of the fire-stricken are, where fire blazes and smoke plumes were detected.  The fires have been raging near the city of Haifa - the third in size city in Israel - starting 2nd December. According to the estimates of the experts over 2,000 hectares of forest have been burnt and over 40 people died. Fire brigades from... (read more)

Satellite Imagery to Shell Desktops

ER Mapper (Australia) has rolled out a new software solution for Shell exploration and production that makes Shell's twelve terabyte archive of satellite imagery available to users throughout the world. The solution was built by ER Mapper's enterprise services team and features the Image Web Server product, which uses patented image compression and serving technologies to provide a fast and responsive system, even when serving very large images to many users. Using a web browser, users simply zoom to a particular location to see the list of images available for that area. They can then ask for information about the... (read more)

Navteq Unveils DTM, Satellite Imagery

Navteq (IL, USA) has launched Digital Terrain Model and Satellite Imagery which enable richer, more realistic map display in location-based and navigation applications. These are in addition to NAVTEQ's 2D Landmark Footprints, Enhanced 2D Footprints, 3D City Models and 3D Landmark products. Digital Terrain Model provides three dimensional elevation data that reflects the relative height of the earth's surface. This is further enhanced with texture and colours to help users better understand where they are in relation to surrounding natural landmarks.   Satellite Imagery adds realism to map display and helps consumers more easily orient themselves in the real world...

50cm Imagery Satellite Preparing for Launch

Astrium Geo is working to launch the Pléiades 1 satellite on 16th December 2011 on a Soyouz rocket leaving from Kourou spaceport in French Guiana. It is the first of two identical satellites that will image the Earth, delivering 50cm imagery products, for more than ten years. Such a high resolution paves the way for finer mapping, more detailed photo interpretation, enhanced services and a new range of high-resolution 3D products.   Pléiades has been designed with maximum reactivity in mind. It will be accessible through innovative tasking services, allowing access to new imagery faster than ever. This reactivity is... (read more)
