AbstractIn preparation for global vegetation monitoring, a study was undertaken to integrate NOAA AVHRR, ecological, and meteorological data sets using both image analysis and geographic information system technology.
Normalized Difference Vegetation Index (NDVI) values derived from NOAA imagery at 4km resolution were acquired for the growing season of 1986. Ecological districts obtained from the Canada Land Data system (CLDS) were used to stratify the AVHRR data by vegetation and soil type. A soil moisture budget model was applied to land cover information, precipitation and temperature data to derive potential and actual evapotranspiration rates and soil moisture reserves for each study sites. NDVI composites over 15 day periods were used to investigate the relationship between vegetation development and the derived environmental parameters. Output from the model indicates that the model developed for the 1986 growing season correspond significantly with the vegetation patterns observed by remotely sensed means.
