dc.description.abstract | The use of satellite imagery to monitor vegetation has been important for decades. Previous studies focus on the use of A VHRR based vegetation indices to assess vegetation response to climatic conditions. This study focuses on the relationship between the Palmer Drought Severity Index (PDSI) and different vegetation types through the use of several vegetation indices derived from Landsat ETM+ data (NDVI, Tasseled Cap, and SAVI). The methodology for this study consisted of three major phases; (1) obtaining georeferenced PDSI values that correspond to available imagery, (2) statistical comparison between PDSI and average values from vegetation indices, and (3) utilizing the results to make temporal inferences about the condition of vegetation in a portion of the Cuyahoga River watershed in northeastern Ohio. The potential existence of a lag between the onset of climatic conditions and vegetation response was partially addressed using these correlation methods. | |
