KurzfassungThe Remote Sensing (RS) is a modern analysis methodology of the earth surface conditions. The RS main principle is to measure electromagnetic radiation reflected from land surface. Recorded is either solar electromagnetic radiation (optic pictures) or electromagnetic emanation of radars (radar images). The RS is used for specific applications in the areas of agriculture and environment. The Slovakian company is looking for farmers or agriculture companies in order to transfer its knowledge.
Remote sensing does include a group of techniques for collecting image or other forms of data about an object from measurements made at a distance from the object, and the processing and analysis of the data.
Remote sensing technology does include GIS, GPS, radar, image processing, photography, accuracy assessments, information management.
- Various satellites exist at present time, as e.g. Landsat TM (USA), SPOT (France), IRS (India), some of Russia; their image records can be used in agriculture and at soil conservation in a versatile way. The satellite image records main advantage is their multi-spectrality, i.e. these images have several zones of electromagnetic radiation, as e.g. visible spectrum, near infrared radiation, etc. This allows to know the degree of dependence of electromagnetic radiation reflectance from moisture, Fe oxides levels, humus, soil forming substratum in the case, e.g. erosion detection, as well as water-logging. Also salinisation is demonstrated by electromagnetic radiation reflection change.
Satellite image records have relatively high spatial resolution, as it ranges 1 m (satellite EU IKONOS) – approximately 30 m.
Also by taking stock of the crops, various crops appear by another reflectance depending from vegetation type. Crops can be identified relatively simply from the satellite image by this principle. Even yield level can be predicted by the vegetation index NVDI that is depending from biomass amount, i.e. there is a possibility to do comparisons with previous vegetation periods.
- The Radar images, mainly those from the radars ERS and RADARSAT are an important source of soil data. Their implementation is effective when optic satellite images cannot be used, as the radar satellite images are independent from cloudiness. Their disadvantage is their lower identifying capacity.
- Aerial photo offers high identifying ability and allows exact areas size determination, land relationships, etc. Unfortunately, this technology is expensive, limited by vegetation, and has small territory extent. However, despite these disadvantages aerial images photo with satellite image records is an unique source of information for land use planning, rubbish dumps monitoring, pollution mapping, canopy harms, etc.
In the Soil Science and Conservation Research Institute, Bratislava, RS advantages are used to find solutions to agriculture and environment problems. Remote sensing data, both satellite images (optic, radar) or aerial photo can be utilised for their multilateral application and gain good information in the community various spheres. They become an important part of the Soil Information System at the Soil Science and Conservation Research Institute, Bratislava. The RS data are used by the programs belonging to the soil geographic information systems (GIS). In combination with other data layers the RS are very important.
The range of applications includes land-cover and land-use mapping, cloud tracking, snow cover mapping and air temperature monitoring, topographic mapping, geological classification and soil erosion modelling, including detection, the assessment of forest canopy structures, in-stream sediment movement, monitoring endangered and more common wildlife species, ecosystem management, wetland mapping, wildfire management, and precise GPS positioning.
RS data use in agriculture satisfies newest trends in EU countries and is harmonised with the JRC (Joint Research Centre) strategy. The Soil Science and Conservation Research Institute was during the nineties EU focal point for the problems of crops inventory, yield estimation and soil degradation mapping with the help of RS methods. Its main advantages are its relative low cost compared to classical terrestrial methods, its exactness, objectivity, relative large area catch (particularly satellite image records), as well as the possibility to obtain reciprocal materials independent from mapping (i.e. satellite makes images in regular intervals, in depending from orders).
RS data are anchored predominantly; they are economically profitable with comparison to classical terrestrial methods.
RS methods use at subsidies audit (aerial aspect) was declared as obligatory by the EC regulation. Their advantage is rapidity and exactness.
