Surveying and official mapping of Pakistan are the responsibility
of Survey of Pakistan (SP), which was created from
Survey of India (SI) after independence in 1947. SP was at
first based in Karachi but headquarters are now located in
Rawalpindi. Like other countries in the subcontinent
mapping systems are derived from standards established
during the imperial era by Survey of India. The basic scale
is a 1:50,000 scale topographic map using the same sheet
lines as earlier SI one-inch mapping and based upon a
Lambert conical Conformal projection, Everest ellipsoid.
1:50,000 sheets are photogrammetric maps, cover 15' quadrangles
and metric editions have been published since 1975.
A 1:250,000 scale series is complete in 119 sheets and
derived from the 1:50,000 map.
A 26-sheet 1:500,000 scale series was completed between
1968 and 1986 on a polyconic projection, and shows relief
with hypsometric tints. SP also publishes a number of
general maps of the country, including province maps at
1:1,000,000 scale. An atlas of Pakistan was issued in 1990,
with mapping at 1:1,000,000 scale and a variety of themes
published at 1:5,000,000. Larger scale programs from SP
include guide maps to towns and cities.
Soviet military topographic mapping of Pakistan is available at the following scales: 1:1,000,000 (10 sheets, complete coverage, published 1957-1990);
1:500,000 (26 sheets, complete coverage, published 1956-1989); 1:200,000 (176 sheets, complete coverage, published 1976-1991); 1:100,000 (589 sheets, complete coverage,
published 1967-1990); 1:50,000 (143 sheets, primarily Afghanistani border coverage, published 1983-2000) and city (1:10,000 to 1:25,000) topographic mapping of 20 major cities
from Bahawalpur to Sukkur published between 1972 and 1983. These product are available in print, digital raster and digital vector GIS formats from
