Since the advent of Geographic Information Systems (GIS) people specialised in this area or connected with GIS at an administrative or user level have been looking for economical and productive means to accomplish data acquisition tasks. Because the data acquisition constitutes a major part of any GIS, the scientific community, especially geodetic surveyors, have come up with the real time kine...

Mobility is an emerging concept in the GIS (Geographic Information Systems) domain and according to some specialists it will introduce a revolution on the way GIS users interact with their data. With this paper, we propose a system architecture for a global, fully mobile and location based GIS system, creating an abstraction to support generic multi-level geo-referenced data, from satellite ima...

This paper provides a review of geographic information system (GIS) technology and its potential use in the SA sugar industry. A brief history of the SASEX GIS is given, as is a description of the software used. Examples of some current GIS research applications at SASEX, such as soil erosion work, yield potential mapping and cane burning investigations are discussed, and mention is made of som...

satellite data have been used for temperature modeling both in urban areas and water. this paperstudies viability of aster satellite images that provide high spatial and spectral resolution to model watersurface temperature, as a fundamental water quality parameter. this study is focused on dez dam reservoirresiding in khuzestan province, south west of iran. after the image corrections required...

17 Abstract—This study outlines a method for generating an 18 automated micro-landform map of an alluvial plain for 19 further flood hazard assessment by combining Shuttle Radar 20 Topographic Mission Digital Elevation Model (SRTM DEM) 21 and satellite images. Average elevation and channel features 22 extracted from DEM are associated with soil moist condition 23 (thresholds of Modified Normali...

A strong earthquake with magnitude 6.5 struck the city of Bam in the southeast Iran on December 26, 2003. The earthquake brought massive destruction to the city and its surrounding rural areas. The earthquake caused the deaths of approximately more than 26,000 residents and injured about 30,000. QuickBird captured a clear image of Bam on January 3, 2004, eight days after the event. The city was...

The demand for accurate and up-to-date spatial information is increasing and its availability is becoming more important for a variety of tasks. Today’s commercial high-resolution satellite imagery (HRSI) offers the potential to extract useful and accurate spatial information for a wide variety of mapping and GIS applications. The extraction of metric information from images is possible due to ...

The reflections recorded on satellite images have been affected by various environmental factors. In these images, some of these factors are combined with other environmental factors that cannot be distinguished. Therefore, it seems wise to model these environmental phenomena in the form of hybrid indicators. In this regard, satellite imagery and machine learning methods can play a unique role ...
