This method encompass two operative phases: a rapid mapping of all the most important natural and artificial elements connected to the hydraulic risk and a reasoned analysis of the collected information with some topographic data that are usually stored in the public offices. The first step includes...
Multi-image matching for DTM generation from SPOT-5 HRS/HRG imagery for the Project of West China Topographic Mapping at 1:50,000 scale High-resolution satellite images (HRSI) at sub-5 m footprint such as IKONOS and SPOT-5 HRG/HRS images are becoming increasingly available to the earth ...
The Ministry of Finance of the People's Republic of China provided the funding for this project. The Ministry of Land and Resources is re- sponsible for the project's management. The coordinating organisations are the China Geological Survey and the Chinese Academy of Geological Sciences. The ...
Alternative Methodologies for the Internal Quality Control of Parallel LiDAR Strips Light Detection and Ranging (LiDAR) systems have been widely adopted for the acquisition of dense and accurate topographic data over extended areas. Althou... A Habib,AP Kersting,KI Bang,... - 《IEEE Transactions ...
Vertical Component of Topographic Survey Vs. SRTM, ICESat, and NED Elevations for Dallas Levees Project Area Introduction The elevations can be incorporated and utilized for a variety of applications including terrain reductions for regional geoid modeling (Marti, 2004), characterization of urban areas...
for Tropical Forest Science (CTFS) (Losos and Leigh2004) to compare the vast amounts of spatial information contained in these data sets. The results show that pairwise associations between species were more variable in sites displaying greater topographic heterogeneity, which is consistent with the...
Unsupervised, supervised and simple knowledge-based classifications were used in the preliminary stage to develop visual representations of soil-landscape patterns and to plan for field data collection. As more was learned about the survey area from data collection, a knowledge-based decision-tree ...
science disciplines. The base topographic data necessary for watershed analysis in many jurisdictions is typically contained within two primary photogrammetrically interpreted base topographic layers: the hydrology (streams, rivers, wetlands, lakes, etc.), and the elevation (contours, spots, digital terrai...

Environment Agency flood hazard data, National Census socio-economic data and Ordnance Survey topographic map data have been used to evaluate and map coastal flood vulnerability, examining neighbourhoods within census wards. This led to a subsequent analysis of Coastal Flood Risk, via the combination ...
