Preparation of Topographic Maps Using Aerial Imagery for Irrigation and Drainage Network Design in Uganda

Project Objectives

  • To produce 1:2000-scale topographic maps using available aerial imagery to identify and evaluate the most suitable locations for the development of irrigation and drainage infrastructure.
  • To establish an integrated geospatial database for technical, economic, and environmental analyses.
  • To facilitate the optimal design of irrigation systems through the high-accuracy topographic datasets and Digital Elevation Models (DEMs).

Scope of Consultancy Services

  • Production of topographic maps required for the feasibility studies and engineering design of large-scale irrigation development projects in the Mount Elgon, Rwenzori, Agoro Hes, and the southwestern highlands of Uganda.
  • Pre-processing of available aerial imagery and generation of high-accuracy three-dimensional terrain models based on precise exterior orientation parameters.
  • Preparation of engineering topographic maps to support the design of irrigation canals, pumping stations, regulating reservoirs and dams, and associated hydraulic structures.
  • Development of Digital Elevation Model (DEMs), slope maps, and aspect maps for hydrological studies, terrain analysis, and water transfer system design.
  • Preparation and delivery of base maps in GIS and CAD-compatible formats.

Key Features

  • Mahab Ghodss’ first international Geomatics Engineering project in East Africa.
