This study presents a novel approach for building change detection from digital surface models (DSMs), which are generated from the images acquired by a multi-line digital airborne sensor ADS40. Our approach is based on building extraction, which is one of the most challenging research fields. A scheme is proposed that allows efficient integration of a local surface normal angle transform (LSNA...

The rapid development of urbanization requires land management business should change the former single systematic pattern, and advance to integration of functions and data sharing. In order to meets the requirement, this paper presents a new thinking for land management pattern, and management tools of data center for integration of urban and rural areas. The tools were based on MapGIS, which ...

As a result of urbanization, land use/land cover classes in urban areas are changing rapidly, and this trend increased 11 in the recent years. Change information detected from multi-temporal remote sensing images can thus help to understand 12 urban development and to effectively support urban planning. Differences in reflectance spectra, easily obtained by 13 multi-temporal remote sensing imag...

Detailed studies on the spatiotemporal patterns of urban agglomeration in the Middle Yangtze River Basin (MYRB) are rare. This paper analyzed the spatiotemporal patterns of urbanization in the MYRB using multi-temporal remote sensing data circa 2000, 2008 and 2016 integrated with geographic information system (GIS) techniques and landscape analysis approaches. A multi-level analysis of the rate...

The paper shows that a Multi-layer Perceptron (MLP) operating on a sliding window of multi-spectral MODIS timeseries data is able to detect simulated change which was introduced by concatenating timeseries of two pixels belonging to two different land cover types. This approach requires training data and is thus supervised. An unsupervised change detection method is proposed based on a non-line...

iran has mountainous landscapes and half of its surface is occupied by highlands. moreover, iran is an arid country and deserts are located at lower altitudes. most metropolitan areas are positioned in mid-altitudes between mountain and desert. cities grow upwardly toward the highlands under pressures of urbanization and desertification. foothill ecotones are a zone between upland mountains and...

today, environmental crisis and loss of natural resources are the principle causes of the creation of environmental management systems. the optimal management of natural resources requires the assessment and classification of ecological and environmental potentials. using this method, the abilities and restrictions of resources can be recognized, and their future trends can be predicted. nebka ...
