Service Description: This map is created by georeferencing the Middle East oil and gas fields map published by United States Central Intelligence Agency (CIA) in 2007. Parrallel and meridian intersections on the map are used as control points and the second-order polynomial transformation is applied to georeference the map to a Lambert Conformal Conic projection based on the WGS 1984 datum. The map states the standard parallels used in the map projection, but not central meridan. East 45 degress is selected as the central meridian. 16 control points are used. Total RMS error is 429.7 meters with individual residuals ranging 96.7 - 649.8 meters. Alignment appears good with Esri World Street basemap at the scale of 1:1,000,000. The source map is downloaded from Library of Congress at https://www.loc.gov/resource/g7421h.ct002142/
