2. Level II Transverse Mercator Digital Data Enhancements

   The East-Central Labrador Ecological Land Survey (ELS) data in
   Transverse Mercator have ungergone the following transformation
   from their original Level I representation:

   a) All sixtewen map sheets have been horizontally integrated
      so as to form a single mosaic for the entire study area.

   b) The mosaic data are vertically integrated with a corresponding
      shoreline layer, i.e. an additional variable qualifies each
      polygon as being a land or water area.

   c) The data are projected to Transverse Mercator projection,
      and the attribute tables therefore contain valid length and
      area measures in square meters and meters resp. The projection
      is similar to UTM but overcomes the problem of the two UTM
      zones within the study area.
