Introduction and Objectives: The centers work of Anderson et al. (2001) [1] identified two prominent centers in the Tharsis region, Syria Planum and Alba Patera (Stage 2 and Stage 4 respectively). Because of their perceived influence on the geologic and possible paleoclimatic histories of Mars, Mars Orbiter Laser Altimetry (MOLA) along with published stratigraphic and paleotectonic information ...

the objective of this research was to study the relationships between edaphic and topographic factors with distribution of plant species. for this purpose, current study was conducted in eshtehard rangelands of tehran province. the sampling method was randomized–systematic and in each sampling unit, three parallel transects with 750 m length containing 45 quadrates (according to vegetation vari...

Understanding the maintenance of high tropical tree species diversity requires disentangling the effects of habitat vs. geographic distance. Using floristic, topographic, and soil nutrient data from 105 0.6-ha plots in mixed dipterocarp forest throughout Sarawak, Malaysian Borneo, we explore the degree to which floristic patterns are habitat-driven from local to landscape scales. We assess how ...

An increasing number of thematic datasets are published as RDF graphs and linked to other datasets by identifying equivalent resources in other relevant datasets. Among the set of properties usually used as data linking criteria, geolocation (addresses, locations, coordinates ) remains one of the most commonly used. However, resources that actually refer to complex topographic features are gene...

The purpose of this study was to investigate the clinical characteristics and assess other factors associated with geographic tongue in Thailand. One hundred and eighty-eight Thais with geographic tongue and 188 controls were interviewed regarding their medical history, symptoms, and the nature and migratory pattern of their lesions. Variations in the clinical appearance, lesion location, and a...

We advocate a desktop virtual reality (VR) interface to a geographic information system (GIS). The navigational capability to explore large topographic scenes is a powerful metaphor and a natural way of interacting with a GIS. VR systems succeed in providing visual realism and realtime navigation and interaction, but fail to cope with very large amounts of data and to provide the general functi...

We investigated the influence of hillslope scale topographic characteristics and the relative position of hillslopes along streams (i.e., internal catchment structure) on the isotopic composition of base flow in first-order, forested headwater streams at Coweeta Hydrologic Laboratory. The study focused on two adjacent forested catchments with different topographic characteristics. We used stabl...

Digital Elevation Model (DEM) is main input for watershed modelling. Recently, available online free in different accuracies, and spatial resolutions as a product of several remote sensing satellites. Hence, it necessary to find out which one the best modeling study area. In this study, accuracies 30m resolution DEMs (Copernicus, SRTM, ASTER) can be examined by using Remote (RS) Geographic Info...
