Mapping of the wealthy Gulf state of Qatar is coordinated
through the Center for Geographic Information Systems
(QCGIS), established by the Cabinet of Ministers in 1990.
The map base of the peninsula was created in the period
between 1947 and 1984 by Hunting Surveys in response to
oil exploration needs. Modern photogrammetric surveys were
carried out in the 1970s and a new geodetic framework was
established, including the Qatar national grid, and mapping
standards based upon the use of UTM specifications. Grid-based
sheet lines have been used for series at scales from
1:100,000 through to 1:500 urban mapping. Basic scale
mapping in the 1980s was carried out by the Engineering
Services Department which produced maps at 1:5,000,
1:2,000, 1:1,000 or 1:500 scales depending upon the area.
1:5,000 and 1:2,000 scale maps showed relief with 1 m
contours; the larger scale plans used spot heights and were
uncontoured. Data were revised on a regular basis. Derived
printed maps were in four colors with English and Arabic
lettering. National coverage at 1:10,000 scale required 281
sheets, with 2 m contours, 1:50,000 scale maps covered
Qatar in 15 sheets with contours at 2 m or 4 m intervals,
while 1:100,000 scale mapping needed four sheets and
showed relief with 4 m contours. A single 1:200,000 scale
map of the state was also maintained.
The best available coverage of Qatar is Soviet military topographic mapping, it exists at the following scales: 1:1,000,000 (1 sheet, complete coverage, published in 1983);
1:500,000 (4 sheets, complete coverage, published 1977-1982); 1:200,000 (9 sheets, complete coverage, published in 1975); 1:100,000 (18 sheets, complete coverage,
published 1978-1984) and a city (1:10,000) topographic map of Doha published in 1979. These products are available in print, digital raster and digital vector GIS formats
