Precision agriculture recommends a sustainable employment of nutrients and water, according to the site-specific crop requirements. In this context, the knowledge of soil characteristics allows to app...
One of the outputs of mapping activity in Indonesia is Digital Terrain Model (DTM). DTM generated by stereo plotting with photogrammetry concept, where Indonesia Topography Map at medium scale using S...
In this paper we propose a new algorithm for digital terrain (DTM) model reconstruction from very high spatial resolution digital surface models (DSMs). It represents a combination of multi-directiona...
A method of extracting bare-earth points from photogrammetric point clouds by partially using an existing lower resolution digital terrain model (DTM) is presented. The bare-earth points are extracted...
Airborne pushbroom systems for the direct acquisition of digital imagery enable the simultaneous capture of high quality 3D and multispectral information of a scene. The combination of geometric and r...
Using high resolution optical satellite imagery for automatic DTM generation the validation of the digital terrain model becomes an issue. This problem is easily to overcome if a DTM already exists, a...
In this paper the accuracy of automatic DTM computation on the digital photogrammetric workstation DPW770 of LeicaHelava will be discussed. The software component of the photogrammetric System is the ...
Cartosat-1 is the eleventh satellite of the Indian Space Research Organisation series and is primarily meant for topographic mapping and Digital Terrain Model (DTM) generation. In the framework of the...
High-resolution satellite images (HRSI) at sub-5m footprint such as IKONOS, IRS-P5 (CartoSat-1) and SPOT-5 HRG/HRS images are becoming increasingly available to the earth observation community and the...
Airborne laser scanning systems provide high quality 3D point clouds from the earth’s surface. A Digital Surface Model (DSM) is provided from the LIDAR data after removing the outliers from the point...
In the frame of our long term, interdisciplinary Nasca/Palpa project, conducted in a close cooperation between our group and archaeologists from the German Archaeological Institute (DAI, KAAK Bonn), ...
The High Resolution Stereo Camera (HRSC) on Mars Express covers the surface of our neighboring planet in full color and 3D. Altogether, nine channels are obtained in stereo angles between ±18.9°. The...
In the past years laser scanner data has established itself as an accurate and reliable data basis for many applications. Highly accurate digital terrain models (DTM) can be derived by filtering las...
Airborne laser scanning (ALS) has become an established tool for acquiring digital terrain models (DTM) in forested areas. Even though, there have been several empirical studies on DTM quality with l...
The Nasca-Project at ETH Zurich aims for a GIS-based analysis of the topography and the geoglyphs carved into the ground by the ancient Nasca (200 B.C. – 600 A.C.) in the desert region of Nasca/Palpa,...
