AN OPTIMISED SYSTEM FOR GENERATING MULTI-RESOLUTION DTMS USING NASA MRO DATASETS
multi-resolution DTM MRO CTX HiRISE CASP-GO
2016/7/27
Within the EU FP-7 iMars project, a fully automated multi-resolution DTM processing chain, called Co-registration ASP-Gotcha Optimised (CASP-GO) has been developed, based on the open source NASA Ames ...
A procedure for map updating using digital mono-plotting and DTMs
procedure for map updating digital mono-plotting DTMs
2016/5/20
The production and updating of maps of the terrain surface is a procedure that can be done easily by using aerial photographs. In general this procedure needs to use expensive equipment that are not a...
High quality DTMs from contourlines by knowledge-based classification of problem regions
High quality DTMs contourlines knowledge-based classification problem regions
2016/5/20
Contourline maps are increasingly used to generate DTMs (Digital Terrain Models). That's, because in most countries such maps are existing, covering the whole area in different scales, thus representi...
Automated Noise Reduction in HRSC Mars DTMs
Extra-terrestrial Mapping DTM Surface Matching Geology Noise Detection
2015/12/17
Since the European Space Agency Mars Express spacecraft entered an orbit around Mars, the High Resolution Stereo Camera (HRSC) placed onboard has been imaging the Martian surface. Due to the character...
A Hybrid Method for Deriving DTMs from Urban DEMs
DEM/DTM urban aboveground correlation segmentation classification triangulation Random Markov Field
2015/12/8
This study focuses on the automatic extraction of DTMs from urban DEMs produced by image correlation. Many methods have been proposed in the literature yet processing correlation DEMs in any kind of a...

validation of dtms beneath forest canopy derived from p-band polarimetric insar.
采用电化学技术在LY12铝合金表面沉积制备了十二烷基三甲氧基硅烷(DTMS)膜. 反射吸收红外光谱表明, DTMS硅烷试剂与铝合金基体表面发生了化学键合作用, 生成—SiOAl键实现成膜. 通过对膜覆盖电极在质量分数为3.5%的NaCl溶液中的电化学阻抗谱(EIS)测试结果表明, 与开路电位下相比, 采用阴极电位沉积方法得到硅烷膜的耐蚀性能有明显提高, 且存在一个最佳“临界电位”, 在此电位下沉积...
Morphometry and kinematics of landslides inferred from precise DTMs in West Belgium
Morphometry kinematics landslides precise DTMs West Belgium
2009/12/25
The Flemish Ardennes (W Belgium) are known to be affected by deep-seated landslides. The assessment of the landslide reactivation hazard requires understanding the driving processes and delimiting pre...
