Abstract

Detecting vegetation change using historical aerial photo sequences
Track: Imagery
Authors: Yi-Chin Fang

The Irvine Ranch contains some of the most intact remaining southern California’s coastal sage scrub, chaparral, oak-sycamore woodland and grassland communities. These habitats have historically experienced several disturbance, such as grazing, fragmentation and high fire frequency. To understand how these factors have influenced vegetation change, we used ENVI and ArcGIS 10 to analyze a sequence of temporal historical aerial photographs using remote sensing as well as direct visual analysis.
