This line feature class was created to model flight lines on geo-rectified aerial photography for the State Water Project. The coordinate system for this feature class is NAD_1983_CaTM. The purpose for the creation of this dataset is to help classify the various flight groups according to the corresponding project ID and supply relevant spatial data information. To create the flight lines, archived aerial photography was first scanned and converted to .tiff file format that would be later geo-referenced to NAIP 2016. The photo centers at the ends of each fight line would be marked using the polygon drawing tool by creating an "X" from the vertex of each corner fiducial. The flight line would then be created using these photo center as reference end points using the "create feature" option in the editor toolbar. |
