Elfin Forest Aerial Photo Collection
SWAP has put together a small collection of aerial photographs from various sources showing the Elfin Forest over time. The earliest is by the U.S. Dept. of Agriculture from 1937 (compliments of Morro Bay National Estuary Program). Most are from the early efforts to purchase and establish the Elfin Forest Natural Area or flown were for SWAP so we can see how the restoration of the Forest is progressing. Below is a selection of eleven aerials that best show the effects of time.
These photos have been cropped and rotated to show the same area and pretty much overlay each other. Due to the vegaries of aerial photography the overlay is only approximate. Making copies that exactly match is a future and more difficult task.
You download the aerials by simply clicking on the year of interest. Once the picture appears you should be able to save or print it. You will note there are two copies of some photos. This is because some of the originals a quite large in size. The second set has been compressed to no more than 0.5 MB. The larger files from 2002 to 2007 are quite detailed to the point that individual planks in the boardwalk are visable.
Should you want to use any of these photos in a publication please contact the webmaster for the citation information. Additional photos will be added as time permits. A couple have been rectified and put into "UTM space". These can be used in ArcView and yield reasonably accurate distance measurements.
