Understanding the effect of aerosols on climate requires knowledge of the size and chemical composition of individual aerosol particles-two fundamental properties that determine an aerosol's optical properties and ability to serve as cloud condensation or ice nuclei. Here we present our aircraft-compatible single particle mass spectrometers, SPLAT II and its new, miniaturized version, miniSPLAT...

ecotones are zones of gradual changes from an ecological system to another.ecotones monitoring could be important to find out the reason for changes and limits. inthis research satellite data were used to analyze the ecotone boundary in fars steppicrangelands using irs liss iii and pan data of year 2006. the real vegetation map andecotones prepared through geo-eye images from google earth softw...

Earth system science has changed rapidly due to global environmental changes and the advent of observation technology. Therefore, new tools are required monitor, measure, analyze, evaluate, model data. Google (GE) was officially launched by in 2005 as a ”geobrowser”, Engine (GEE) released 2010 cloud computing platform with substantial computational capabilities. The use these two or platforms v...

Background: WHO AnthroPlus is a software which helps us to assess the nutritional status of school-age children and adolescents based on the new WHO Growth Reference 2007. Global Positioning System (GPS) with google earth is an innovative approach to map the spatial distribution of morbidities at the field level. The present study was undertaken to assess the nutritional status of school age ch...

Using freely-available data and open-source software, we developed a remote sensing methodology to identify mining areas and assess recent mining expansion in Myanmar. Our country-wide analysis used Landsat 8 satellite data from a select number of mining areas to create a raster layer of potential mining areas. We used this layer to guide a systematic scan of freely-available fine-resolution im...

PROBLEM Traditional random sampling at community level requires a list of every individual household that can be randomly selected in the study community. The longitudinal demographic surveillance systems often used as sampling frames are difficult to create in many resource-poor settings. APPROACH We used Google Earth imagery and geographical analysis software to develop a sampling frame. Ev...

Google Earth provides an open source, easy to access and cost free image data that support map interest community. Therefore, depending of this community on Google Earth, grows up day by day. More than simply providing locational information, Google Earth allows users to add their own content such as photos or descriptions of areas or landmarks. They can also extrapolate information from the sa...

Topographic data or DEMs are commonly perceived as providing loaded information for hydrological modelling. However, this information severely limited, and most users rely on published topographic maps or DEMs produced by government agencies. This paper proposes an alternative method of generating DEM by using online source of elevation data which is easier and free. The result shows that, the ...
