High-resolution images available on Google Earth are increasingly being consulted in geographic studies. However, most studies limit themselves to visualizations or on-screen measurements. Google Earth allows users to create points, lines and polygons on-screen, which can be saved as KML files. Here, the use of R statistics freeware is proposed to easily convert these files to the shapefile for...

An integrated GPS-GSM system is proposed to track vehicles using Google Earth application. The remote module has a GPS mounted on the moving vehicle to identify its current position, and to be transferred by GSM with other parameters acquired by the automobile’s data port as an SMS to a recipient station. The received GPS coordinates are filtered using a Kalman filter to enhance the accuracy of...

With no easy means of monitoring the WSN, it was time-consuming to resolve problems. An easy to understand, visual method of monitoring the health of the WSN in real-time was therefore deemed essential. A Google Earth-based user interface was created which clearly highlighted any problems in the WSN operation. Carefully positioned sensor nodes collect and monitor information about their health ...

ABSTRACT: Just a few years ago spatial data was only relevant for surveying and mapping authorities (land registries). In the meantime the situation is a completely different one. Navigation systems or services like Google Earth and Google Maps lead to broad awareness of spatial data. Using the Oracle technology as an example the session gives an overview about combining spatial with business d...

In Ghana, there is general indiscipline and lack of transparency in the land market. This is characterized by multiple sales of residential parcels, land encroachments and haphazard development. Land records form the bases of all land reforms and therefore regular online update of land records is essential.The objective of the web-based land records system therefore was to provide a quick, secu...

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 ...

The high resolution and span diversity of colored Google Earth images are the main reasons for developing a vegetation extraction mechanism based on BPNN (Back Propagation Neural Networks) that can work efficiently with poor color images. This paper introduces a method based on neural networks that can efficiently recognize vegetation and discriminate its zone from the desert, urban, and roadst...
