Abstract

This research has computed the rectangular coordinates of points on map of Iraq
from geographical coordinates by conical conformal projection with two standard
parallels ( St1, St2 ) at (30º N , 36º N) in this work the computations included the effect
of scale factor at all parallels along the map of Iraq and represent it graficaly to show the
distribution of error in scale factor .The distribution of values of scale factor at universal
transver Mercator projection ( U. T.M ) was drawn to show the comparison .om the
comparison and the results obtained it can be seen that the Lambert conical conformal
projection is a suitable projection to present ; Iraqi topographic maps with accurate
values .
