For more than 5 years now, GEO-K has been conducting a variety of Earth-Observation application-development projects leveraging the use of radar and optical data to generate thematic maps, hydrocarbon pollution maps and update land use classification. One such software is Neumapper, which processes remotely sensed imagery using an artificial neural network computational model.
Change detection is an automated process that generally consists of comparing images acquired on two or more different dates. A recent image can also be compared to a geospatial database to spot differences, mainly in terms of the size of mapped linear or surface features.
Our change detection services are used to:
Assess logging activities caused by forest fires and etc.; monitor urban sprawl and wetlands; detect cm-scale surface movements impacting critical infrastructures.
GEO-K provides you with make use of satellite images acquired during the growing season to generate various agricultural diagnostic tools. Satellite imagery such as RapidEye are especially suited to such a need because of the possibility of acquiring images several times a week.
Crop yield diagnostic tools can be used to: assess plant growth stage and ground cover; produce a vegetation index to indicate crop vigor; produce economic yield maps.
Following natural disasters such as floods or earthquakes, GEO-K may give the authorities in charge images and map information useful for people in the field by: extracting tactical information for emergency situations; providing expertise in the use of radar images in case of heavy cloud cover, particularly for floods.
The combination of satellite optical and radar acquisitions at various spatial resolutions with powerful automatic image processing techniques facilitates the frequent generation of updated worldwide cartography at different scales. During the data production process, one of our thematic specialists extracts the information directly from satellite imagery by using machine learning algorithms.
Our thematic mapping services include: land use mapping; eco-forestry mapping; geomorphological mapping;
Satellite images abound in information that is sometimes hard to interpret and synthesize; they need additional processing to extract information relevant to the user. We carry out several types of image processing to facilitate information extraction. Besides the spectral values of pixels, the object based approach defines and takes into account many of an object’s features. Applied to ocean monitoring, this approach can, for example, detect ships and oil spills in a radar image.
With modern mobile devices, it is possible to use satellite data smartly thanks to the on line applications. GEO-K has already developed two apps for meteorology and geographic edutainment. Many other applications can be developed: satellite data - and more generally images - permit a territory and its institutions adaptable study.
