الملخص EN

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.
