Acquired aerial photography (1:5000 to 1:60 000 scale).
Performed aerotriangulation of photography, geo-referencing all photogrammetric controls to true ground coordinates.
Collected vector digital data using analogue plotters (Wild A10 - A8 - B8S). Vector data were three dimensional (x,y,z) and geo-referenced to UTM coordinates. The output format was DXF.
Performed cursory checks of digital data (removal of pseudo nodes, creation of polygons, etc.).
Built lines and points then copied attribute information from the ACODE and XCODE tables into the arc and point attribute tables (AAT and PAT). Dropped five attribute fields from the resulting attribute tables.
Selected points representing designated areas based on the dxf-layer attribute. Put the points for each designated area category to respective ArcInfo coverages.
Built designated area points then joined all designated area point layers into one coverage.
Appended mapsheet designated area point coverages into a Manitoba-wide coverage and built final coverage.
