The modification of land use is a crucial factor in the dysfunction ecosystems. It greatly influences hydrological cycle basins. This study focused on Oueme basin, which represents almost half total area Benin, and aimed to describe current future evolution its cover using maps Land Use Cover Dynamics project (1975, 2000, 2013). A temporal analysis surface states was performed with QGIS, potent...

The Loess Plateau, known for its fragile ecosystems, is one of the traditional apple-producing regions in China. Although some management measures are needed to enhance sustainable agriculture response rising pressure climate change, geographic distribution apple trees considering multiple variables has not been considered. In this study, we used three software (the maximum entropy model, IDRIS...

This paper raises the question of influence a scholar’s personal experience on their research strategies, which determines selection sources, purpose creating work, its structure, and content. The author refers to A Sketch Countries (Taqwim al-buldan), work Eastern Europe in world geography by Abū al-Fidāʾ, Syrian scholar first third fourteenth century emir city Hama. is reconstruct al-Fidāʾ’s ...

The purpose of this research is to determine the amount and value carbon stock in Southwestern Ethiopia's coffee forest from 1978 2050, as well sequestration 1988 2050. Different time-series satellite data were acquired classified into land-use categories using ArcGIS ENVI 5:0, followed by IDRISI forecasts up finally modeling with INVEST. Data collected within plot constructed a systematic rand...

El objetivo de la presente investigación fue actualizar el mapa climas del estado Jalisco acuerdo con clasificación climática Köppen-García, base en imágenes raster climáticas alta resolución (90 m) y un ajuste por correspondencia climas-vegetación potencial. Se trabajó datos climáticos diarios, mensuales anuales 154 estaciones meteorológicas 151 estados vecinos. Los corresponden a serie 1961-2...

This study analyzed the spatiotemporal pattern of settlement expansion in Abuja, Nigeria, one of West Africa’s fastest developing cities, using geoinformation and ancillary datasets. Three epochs of Land-use Land-cover (LULC) maps for 1986, 2001 and 2014 were derived from Landsat images using support vector machines (SVM). Accuracy assessment (AA) of the LULC maps based on the pixel count resul...

Population estimation was carried out using high-resolution (20 metres) multispectral satellite data (SPOT) in the Kowloon metropolitan area of Hong Kong, which is characterised by high population density and multipurpose high-rise buildings. The smallest areal unit for census data Tertiary Planning Unit (TPU) -was used to aggregate population. With the aid of a raster GIS (IDRISI) and a vector...

The estimation of accuracy of thematic maps derived from remotely sensed data used in conjunction with a geographic information system is presented. A systematic random sampling techique is proposed to asses the accuracy. The main objective of this work is the determination of the optimal sampling intensity and the appropriate sample size used to assess the accuracy. The data set used is a Land...
