Transmission Lines Monitoring from Satellite Images

Forest Canopy Density Monitoring, Using Satellite Images

The increasing use of satellite Remote Sensing for civilian use has proved to be the most cost effective means of mapping and monitoring environmental changes in terms of vegetation and non-renewable resources, especially in developing countries. Data can be obtained as frequently as required to provide information for determination of quantitative and qualitative changes in terrain. Forests as...

Building Extraction from Satellite Images

A method for detecting buildings from satellite/aerial images is proposed in this paper. The aim is to extract rectilinear buildings by using hypothesis. Hypothesis generation is accomplished by using edge detection and line generation methods. Hypothesis verification is carried out by using information obtained both from the color segmentation of HSV representation of the image. Satellite imag...

Using Satellite Images for Drought Monitoring: a Knowledge Discovery Approach

The main objective of this research was to develop a new concept and approach to extracting knowledge from satellite imageries for near real-time drought monitoring in areas of Ethiopia that are experiencing food insecurity. The near real-time data downloaded from the Atlantic Bird satellite were used to produce the drought spatial distribution. Our results showed that approximately 40% of the ...

Wildfire monitoring using satellite images, ontologies and linked geospatial data

Advances in remote sensing technologies have allowed us to send an ever-increasing number of satellites in orbit around Earth. As a result, Earth Observation data archives have been constantly increasing in size in the last few years, and have become a valuable source of data for many scientific and application domains. When EO data is coupled with other data sources many pionner applications c...
