The Royal Jordanian Geographic Center (RJGC) (until
1984 the Jordan National Geographic Center) was established
as the national mapping agency in 1975, with French
and later American aid. It carries out geodetic, aerial and
topographic surveying of the country and publishes topographic
and thematic maps, as well as providing maps for
other official agencies in the country. RJGC serves both military
and civilian mapping needs.
The modern topographic mapping of Jordan was established
by allied military forces during World War II, but geodetic
frameworks and mapping remained unrevised until the new
national mapping agency established primary and secondary
geodetic control in the mid-1970s. Work continues to
update a tertiary control network covering the whole
country. A 1:50,000 scale series provides the basic mapping
and is complete in 184 sheets. This photogrammetric series
is on the Transverse Mercator projection, modified Clarke
1880 ellipsoid, and shows relief with 25 m contours. It is
under regular revision, using aerial photographic coverage,
and is being captured as digital data for inclusion in a
national topographic database held in ARC/INFO. An 84-sheet
1:100,000 scale map is derived from the basic scale, and
1:250,000 scale coverage is also available in 17 sheets, with
100 m contours, the 1:250,000 map is already captured as
digital data. A new program of topographic mapping of
populated areas has also started, and is based upon the UTM
projection and International ellipsoid, with maps being
published at scales of 1:10,000 and 1:25,000.
Soviet military topographic mapping of Jordan exists at the following scales: 1:1,000,000 (4 sheets, complete coverage, published 1973-1990);
1:500,000 (8 sheets, complete coverage, published 1987-1989); 1:200,000 (27 sheets, complete coverage, published 1979-1986); 1:100,000 (73 sheets, complete coverage,
published 1983-1986); 1:50,000 (68 sheets, primarily western country coverage, published 1983-1993) and city (1:10,000) topographic mapping of Amman and Irbid published
between 1975 and 1984. These products are available in print, digital raster and digital vector GIS formats from East View Geospatial.
