Editor's Notes

  • #16: Geospatial Data Abstraction Library http://de.wikipedia.org/wiki/Geospatial_Data_Abstraction_Library http://www.osgeo.org/gdal_ogr Geospatial Data Abstraction Library (GDAL/OGR) is a cross platform C++ translator library for raster and vector geospatial data formats that is released under an X/MIT style Open Source license by the Open Source Geospatial Foundation. As a library, it presents a single abstract data model to the calling application for all supported formats. It also comes with a variety of useful commandline utilities for data translation and processing. GDAL supports over 50 raster formats, and OGR over 20 vector formats. It provides the primary data access engine for many applications including MapServer, GRASS, QGIS, and OpenEV. It is also utilized by packages such as OSSIM, Cadcorp SIS, FME, Google Earth, VTP, Thuban, ILWIS, MapGuide and ArcGIS. GDAL/OGR is the most widely used geospatial data access library. Professional support options are available for commercial software developers desiring assistance integrating and extending GDAL, or dig in yourself and join the development team!

  • #45: NDVI = Normalized Differenced Vegetation Index NDVI ist ein Akronym und steht für „Normalized Differenced Vegetation Index“ (auch Normalized Density Vegetation Index), zu deutsch: „normalisierter differenzierter Vegetationsindex“. Er ist der wohl am häufigsten angewandte Vegetationsindex und wird auf der Basis von Satellitendaten errechnet. [Quelle: http://de.wikipedia.org/wiki/Normalized_Differenced_Vegetation_Index] Engl. Akronym für Normalized Difference (auch: Density) Vegetation Index, dt. Normalisierter Differenzierter Vegetationsindex, oder Normierter Differentieller Vegetationsindex oder Normalisierter Differenzen-Vegetations-Index; aus Satellitendaten relativ leicht zu berechnende Messgrösse für die Biomasse. Satellitensensoren können quantifizierend angeben, welcher Teil der photosynthetisch relevanten Strahlung von der Vegetation absorbiert wird. In den späten siebziger Jahren des 20. Jh. wurde erkannt, dass die Netto-Photosynthese direkt abhängig ist von der Menge photosynthetisch aktiver Strahlung, die von Pflanzen absorbiert wird. Je mehr eine Pflanze während der Vegetationsperiode sichtbares Sonnenlicht absorbiert, umso intensiver ist die Photosynthese und umso produktiver ist sie. Wenn die Pflanze umgekehrt weniger Sonnenlicht absorbiert, ist die Photosyntheserate und damit das Wachstum geringer. Durch die Bildung von Indizes aus zwei oder mehr Kanälen kann die Visualisierung des Biomassegehaltes und des Zustandes der Vegetation stark verbessert werden. Ein solcher Index ist der NDVI. Er wird im Wesentlichen aus der Differenz der Messergebnisse der Kanäle 1 und 2 des Sensors AVHRR (Pixelgrößen um 1 km²) ermittelt, er wird aber auch für Multispektraldaten anderer Sensoren benutzt. [Quelle: http://www.fe-lexikon.info/lexikon-n.htm#ndvi] Vegetation erscheint sehr unterschiedlich in den Wellenlängenbereichen des sichtbaren Lichts und des Nahen Infrarots. Im Bereich des sichtbaren Lichts sind vegetations-bedeckte Flächen sehr dunkel, fast schwarz, wohingegen Wüstenregionen (z.B. die Sahara) hell erscheinen. Im Nahen Infrarot ist die Vegetation heller und Wüsten haben in etwa denselben Helligkeitgrad wie beim sichtbaren Licht. Durch den Vergleich von sichtbarem und infrarotem Licht messen Wissenschaftler die relative Vegetationsmasse. [Quelle: NASA Earth Observatory]
