HOLT 3 - Nutzung hochaufloesender Satellitendaten fuer Aufgaben der Landwirtschaftsverwaltung Thueringens Abschlussbericht

Aim of the project: Introduction of innovative Remote Sensing and GIS Technologies in the field of agriculture. Tasks: Utilisation of panchromatic and multispectral satellite data for the development of the methods for the establishment of a Digital Field Map (DFM) uniform for the whole country, for mapping erosion damages on the base of satellite data, for mapping of meadown and pasture land for agricultural aims, for localisation and characterisation of field heterogeneities for agricultural aims. Project results: - High resolution satellite data (KVR-1000, IRS-1C) represented important instruments for the development of DFM methods and the establishment of map prototypes. An operational data application requires a high data update and data resolution (<1 m). For the statistics of erosion appearances panchromatic images of <1 m resolution taken directly before and after the erosion event and additional stereo images or relief data (DGM, <10 m) are required. - For an operational mapping of meadow and pasture land the automatic multispectral classification including rough LF or outsourcing masks is sitable. Spectrally higher resolved, monosensoral satellite image time series and additional information levels (ATKIS data, DHM and others) are the preferred data base. The identification of field heterogeneitties with a higher position accuracy compared to existing ground maps and their improved characterisation by means of satellite data requires image taking times following in brief intervals to each other (clouds, changes of the subject) and a ground resolution of the satellite data of 1-2 m (mapped ground areas in MMK beginning at 5 m, in RSB 1-2 m). Conclusion: The significance of the satellite-added remote sensing for Thuringians agriculture (agricultural administration and practice) will increase in the first line by the coming operational application of the DFM and thanks to tailor-made supply of satellite data (higher resolution, more usable image-taking, quick access).
