It was then transformed using an affine transformation to latitude and longitude (NAD27) and projected to the UTM system using zone 18 and spheroid Clark 1866 to the NAD27 datum. Arcs were labeled with the relevant year. For polygon coverages, label points were also labeled by year. 2.5.2.2 Source Used Citation Abbreviation: 2.5.2.3 Process Date (completed): 19970112 2.5.2.5 Source Produced Citation Abbreviation: COBB1910UTM27 2.5.2.6 Process Contact (processor) 10.2 Contact Organization Primary 10.1.2 Contact Organization: Virginia Coast Reserve - Long Term Ecological Research (VCR/LTER) 10.1.1 Contact Person: John Porter 10.4 Contact Address 10.4.1 Address Type: mailing and physical address 10.4.2 Address: LTER, Dept.
