e Ie e 00508 32 detection, they are more than acceptable to resource managers that are concerned with canyon- wide changes in sediment, vegetation and camping beaches. An FY 2005 airborne remote- sensing mission to replicate these data on a system-wide scale collection provides the necessary inputs for deternline changes to the resources in the CRE between May 2002 and May 2005. Efforts in FY 2006 will focus on management of these digital data and preparation for serving both the 2002 and 2005 imagery so that change detection anal yses can be accomplished in 2007 through 2008. The next system~wide overflight is proposed for FY 2009. Summary Project Description: In accordance with the DASA program's long-term monitoring goals, an airborne mission to collect digital imagery for the entire CRE from Glen Canyon Dam down to Lake Mead was implemented in May 2005. Those data, along with the 2002 imagery fulfill the proposal currently offered by GCMRC to collect system-wide aerial imagery about every 4 years as outlined in the draft Core Monitoring Plan. The May 2005 dataset is similar to that collected in May 2002, using digital sensors mounted in a fixed-wing aircraft to collect data for both panchromatic and red, green, blue (RGB) bands in the visible spectrum as well as near- infrared data. A Digital Surface Model (DSM) with a I-meter pixel resolution will also be a part of the dataset from this mission. The DSM will be comparable to that collected in May 2002 for change detection in the non-vegetated, open sand areas. For purpose of review, the following is provided as an approximate cost for acquisition of this imagery in 2005. Additional funds are needed to continue supporting management of the expanding imagery dataset in the Oracle data base as multiple data layers are obtained through 2009 (see 2007 budget elements shown in budget table above). .
