TL;DR: In this paper, a multiscale object-specific segmentation (MOSS) approach is presented for automatically delineating image-objects (i.e., segments) at multiple scales from a high-spatial resolution remotely sensed forest scene.

TL;DR: A number of automatic and semi-automatic reconstruction methods are reviewed in more detail in order to reveal their underlying principles and some general properties of reconstruction approaches which have evolved.

TL;DR: In this article, a multi-band wavelet-based image fusion method is presented, which is a further development of the two-band Wavelet transformation, and a set of qualities are classified and analyzed.

TL;DR: The initiator includes a charge of pyrotechnic or explosive material and a valve for cutting off communication between the gas channel and the charge upon initiation of the charge to prevent gases and other reaction products from being exhausted back into the fuse.

TL;DR: In this article, a procedure for the consistent application of digital terrain analysis methods to identify tectonic phenomena from geomorphology is developed and presented through two case studies, where topographic features represented by digital elevation models of the test areas were extracted, described and interpreted in terms of structural geology and geomorphologies.

TL;DR: In this paper, a reference digital elevation model (DEM) from topographic maps at scale 1:250.000 is used in order to assess the vertical accuracy of the SRTM DTED level 1 in Crete Island in Southern Greece.

TL;DR: In this article, the applicability of broadband high spatial-resolution ADAR (Airborne Data Acquisition and Registration) remote sensing data to detect rice sheath blight was examined and a comprehensive field disease index was constructed to measure infection severity of the disease and to relate to image sampled infections.

TL;DR: In this article, a remote sensing based land cover change assessment methodology is presented and applied to a case study of the Oil Sands Mining Development in Athabasca, Alta., Canada.

TL;DR: In this paper, the spectral reflectance of TM channel 5 derived from canopy spectra or image data at grain filling stage was all significantly correlated to grain protein content (R2 = 0.31 and 0.37, respectively).

TL;DR: In this article, the authors discuss the possibilities to use airborne laser scanning for two tasks: change detection and semi-automated 3D mapping of urban environments, while laser scanning is demonstrated to be useful for detecting changes as well as mapping errors.

TL;DR: In this paper, the spectral angle mapper (SAM) technique was used as an attempt to detect the presence of hydroxyl-bearing minerals in the domain of the hydrothermally altered materials.

TL;DR: In this article, a linear spectral unmixing approach was applied to high spatial resolution multispectral imagery to quantify the fractional abundances of the key image endmembers: sunlit canopy, shadow, and soil.

TL;DR: Ferretti et al. as mentioned in this paper used permanent scatterers in differential SAR interferometry to estimate the subsidence rate, and evaluated the feasibility of applying permanent scatter detection to a specific deformation problem.

TL;DR: In this paper, the spectral reflectance curves of soil surface features were derived from spectral measurements both in the field and in the laboratory, and mean reflectance values derived from image pixels representing known features.

TL;DR: In this paper, the authors compared the spectral angle mapping (SAM) and LDI approaches to assess and map land degradation in a small Mediterranean watershed using Advanced Spaceborne Thermal Emission and Reflection Radiometer data and ground-based spectroradiometric measurements.

TL;DR: In this article, the authors describe the soil-vegetation-atmosphere radiative transfer using a combination of the PROSPECT, GeoSAIL, and ATCOR models.

TL;DR: In this article, a region growing segmentation procedure based on texture is applied to extract spatial landform objects from a light detection and ranging (LiDAR) digital surface model (DSM).

TL;DR: In this article, the authors describe the development of a remotely sensed, historical land-cover change database for the northwestern quarter of Chihuahua, Mexico, which consists of multi-temporal landcover classifications and change detection images.

TL;DR: In this paper, the authors presented a recent project to measure urban sprawl in the transboundary region of the Pacific Coast of North America, which includes metropolitan centers of Portland, OR, Seattle, WA and Vancouver, BC, span two nations, three state/provincial governments and dozens of cities.

TL;DR: In this article, the authors used multispectral imagery at a 2.5m resolution with the Multisensor Electro-optical Imaging Sensor (MEIS) to detect discolouration caused by the jack pine budworm (Choristoneura pinus pinus (Free.)).

TL;DR: In this paper, the authors illustrate how archival, historical and remotely sensed data can be used to complement each other for long-term environmental monitoring by cross-linking different forms of data at different temporal scales.

TL;DR: The Land Cover Map 2000 (LCM2000) as discussed by the authors is a comprehensive survey of UK broad habitats giving vector digital maps from segment-based classification of remotely sensed satellite data and the difficulties in applying a user-defined classification.

TL;DR: In this paper, a supervised maximum likelihood classification (MLH) was applied to depict land use changes in Beijing, providing basic maps for planning and development, and the results suggest that ASTER data and the Kohonen self-organized neural network classification can be used as an alternative data and method in a land use update operational system.

TL;DR: The overall conclusion is that the ontology-based framework is feasible, if (1) there is (at least partial) knowledge of the surveying rules, and (2) the data sets can be synchronized in time.

TL;DR: Wang et al. as discussed by the authors studied the impacts of local government-driven reforestation on land use and land cover change, as well as its further impacts on livelihoods of upland farmers in Xizhuang watershed.

TL;DR: In this article, the authors examined the effect of scale incompatibility between soil information and the detailed digital terrain data and remotely sensed information by comparing simulations of watershed processes based on the conventional soil map and those simulations based on detailed soil information across different simulation scales.

TL;DR: A practical system for automated 3-D road network reconstruction from aerial images using knowledge-based image analysis that integrates processing of color image data and information from digital spatial databases, extracts and fuses multiple object cues, takes into account context information, employs existing knowledge, rules and models, and treats each road subclass accordingly.

TL;DR: In this paper, a new, entropy-based approach to estimate the plausible estimates of the spatial distribution of crop areas is described. But, the approach is not suitable for the analysis of large-scale data sets and is computationally intensive.

TL;DR: In this paper, a rapid methodology was proposed to identify burned areas using band ratio's using multitemporal LANDSAT ETM images, evaluate the potential of the burned areas as the source of debris flows based on morphometric parameters (slope and hill slope curvature), and evaluate the structures, such as houses and roads, exposed to potential damage by debris flows.

TL;DR: In this article, the authors give an up-to-date overview of digital airborne sensor systems, including both, large format camera systems and multi-sensor systems (acquiring image and laser scanning data).
