In this paper, we introduce the idea of documenting operational chains for land degradation assessment using ontologies. We believe that this will help end-users in better understanding the land degradation characteristics and evaluate the results of the assessment process. Since the application domain is wide, various operational chains for land degradation assessment and their associated docu...

The Lagoon of Fuente de Piedra in Andalusia, Spain, is a high-value habitat for waterbirds, threatened by expansion and irrigation of olive plantation. This research focuses on detecting the response of land-cover in the lake to water level variation using multi-temporal satellite data, so as to provide information for the nature park management. Objectives of this study are to identify the lan...

The comparison between aerial photographs and satellite images, with regard to their performance, is strongly actual: in fact, advantages and defects of both are well known. In the past , low spatial resolution of satellite images was a limit in cartographical applications : now, the recent orbital platform are improving the data quality and, at the same time, make very large ground coverage po...

The evolution of land development in urban area has been of great interest to policy makers and planners. Due to the complexity of the land development process, no existing studies is considered sophisticated enough. This research uses Dynamic Spatial Ordered Probit (DSOP) model to analyze Austin’s land use intensity patterns over a 4-point panel. The observational units are 300m×300m grid cell...

Landsat TM images of the Pearl River Delta taken in 1988, 1998 and 2006 are used to explore the site factors that influence the construction land expansion in this study. Several site factors, including landscape types and the distances to roads, coastlines, or city centers, had significant impacts on the expansion of construction land, influencing the direction, scale and intensity of the expa...

“Beijing 1” is one Micro-satellite of the international Disaster Monitoring Constellation (DMC). It was launched successfully in 2005, and has high-powered characteristic, such as high gaining data ability, high storage ability, high space resolution, high time resolution and low cost. At present it is necessary to make objective appraisal for image quality and application potential in differen...

Satellite optical images and altimetry data are two major data sources used in Antarctic research. The integration use of these two datasets is expected to provide more accurate and higher quality products, during which data registration is the first issue that needs to be solved. This paper presents an alternative approach for the registration of high-resolution satellite optical images and IC...

This study is a first assessment of fully polarimetric SAR data from the Advanced Land Observation Satellite (ALOS) – Phased Array type L-band Synthetic Aperture Radar (PALSAR) over the test-site of Oberpfaffenhofen in Germany. The polarimetric calibration is checked by using corner reflectors on the Oberpfaffenhofen test-site. Further, the fully polarimetric images are classified by using the ...

In this paper we present an extensive evaluation of visual descriptors for the content-based retrieval of remote sensing images. The evaluation includes global, local, and Convolutional Neural Network (CNNs) features coupled with three different Content-Based Image Retrieval schemas. We conducted all the experiments on two publicly available datasets: the 21class UC Merced Land Use/Land Cover d...
