Change history
| 2/1/2010 |
The data had been tiled to King County's 7500 tiling scheme by Aerial Express. Tiles were loaded to SDW and inventoried. The 7500-ft tiles were built into township SID files (15x compression) using a python-driven MrSid routine. Zone (30x compression) and KeyRegion (75x compression) mosaics were also built. |
| 1/1/2010 |
Data acquired from Aerials Express in January 2010 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. |
