v a :D 0 OdJECTIVE: To study the environmental and ecological impact of the construction and operation of Oakley Damn and Friends Creek Impoundment located on the Sangamon River in East Central Illinois. Personnel involved with the image analysis commenced Phase II - Preliminary Data Analysis, in early . It vwas found the proposed data analysis plan (DAP) could not be used to effectively M- \ process the ERTS imagery; consequently, a newJ data analysis plan (DAP) has been prepared and will be submitted in a few days. r0s 3co I00- To"lWte, the SYM4AP computer programD that will be used extensively W 6@3 uncr M new DAP, is now fully operational. This program will interface 0 Ca co wil tadigital output of H-/ W- a WILD A7 stereoplotter, to be used in the Z - '0 phqtogrametric phases of the project.

No aircraft under- E>~ O'-V flight coverage has been received for the month of December 1972. It cn W L is essential that aircraft coverage be taken of the study area during the sunner (July) and winter (December). The sunmer coverage will allovw IO 0 for the location of environmental changes using vegetation as an indicator. WhC 0 D Winter eoverage will permit an unobstructed view of the earth's i ;4 surface and water courses for environmental changes. Coverage for both H '-.H seasons will be compared to future aircraft coverage and present and future ERTS coverage to locate areas where possible _30~4 H r ,; environmental changes = are occurring. Ground truth data will then be studied to confirm whether 1-p o . 0 or not an environmental change is occurring in the "observed" area. Three data request forms were submitted to the NDPF for additional W O J .zE~ .~ ERTS products on the following dates, 14 November 1972, 9 , and 29 January 1973, none of these requests have been answered as of 8 February 1973.
