Topographical Survey Program
|
To prepare diverse kinds of thematic, political, administrative
and topographical maps, Topographical Survey Branch
was established in B.S. 2032. The programs under this
branch of the Suvey Department. This program publishes
a variety of maps aimed at a diverse section of users
ranging from the Governmental to different projects.
It conducts field surveys for the identification of

prepares, revises, updates and prints all thematic,
political, administrative, topographical and land use
maps. It provides service to its users by providing
aerial photographs, topo-maps national atlas and other
related data for planning and development activities,
research work and education purposes.
The Topographic Survey Branch has provided infrastructure

Survey and publication of topographic base maps were
initiated in 1992 with JICA assistance for Lumbini
zone topographic mapping and rest of the area with
the assistance from Government of Finland. Topographical
maps of whole Nepal has been prepared and its digital
