Change history

9/1/2006	The data had been tiled to King County's 7500 tiling scheme by Aerial Express. Tiles were renamed to King County's standard naming convention and stored in the Spatial Data Warehouse. The tiles were inventoried, selected edge tiles containing very little valid data were removed. The remaining tiles were submitted to an ArcInfo AML-driven grid routine to create temporary tile sets clipped to each of the townships within the extent of the data. These tile sets were then mosaiced and compressed (7x) using MrSid software.
8/1/2006	Data acquired from Aerials Express in August 2006 via portable harddrive. Original delivery did not contain all the required tiles. Aerials Express resubmitted the project area in its entirety in the second harddrive delivery.
