Mapping and Geographic Information Systems (GIS)

Reid Crowther has an extensive background in the preparation of mapping in Nigeria. The first mapping project undertaken by Reid Crowther in Nigeria began in 1987 when aerial photography was flown of the entire metropolitan area. Since that time Reid Crowther has undertaken a variety of air photo mapping, ground survey mapping and satellite imagery projects in Nigeria, these projects include:
  • Mapping of Makaraba Area, Chevron Nigeria - Reid Crowther produced mapping of Makaraba, Okoyitoru and the Makaraba Flow Station to enable the design of the water supply system to serve the villages and the flow station.
  • Line Mapping of Metropolitan Lagos - Reid Crowther prepared digital line maps of the city as it existed. The area covered by aerial photography was 700 sq. km. and the area of mapping covered the 500 sq. km. of urban development that existed at that time.

  • Orthophotographic mapping of Metropolitan Lagos - Reid Crowther prepared fully controlled and rectified orthophoto maps of Lagos. The mapping covered the full 700 sq. km. for which information was available.
  • City of Abuja, FCT - Reid Crowther located all available drawing and records for the City of Abuja and prepared computer based mapping showing details of all properties, roads and water mains for use by the FCT Water Board. The mapping base was used to develop a GIS system for the FCT Water Board.
  • Satellite Imagery for Lagos Island, Ikoyi and the Lekki Peninsula - Reid Crowther provided, procured and developed the necessary ground control to enable the preparation of 100 sq. km. of orthorectified satellite imagery to provide comparisons between Lagos as it existed in 1987 and 2002.
  • Ondo State, mapping of 4 towns - Reid Crowther arranged for the necessary airphoto and ground control to enable the production and preparation of mapping and water main information for 4 towns in Ondo State.

  • Mapping of Adagbraza Area, Chevron Nigeria - Reid Crowther produced mapping of the area along the Benue River covering the communities of Adagbraza and Asantuwagbene to enable the design of the water supply system to serve the two villages.
  • Mapping of Port Harcourt - Reid Crowther prepared mapping of Port Harcourt as part of a facilities improvement and management project for the Rivers State Water Corporation.
  • Mapping of Dibi Area, Chevron Nigeria - Reid Crowther produced mapping of the Dibi area to enable the design of the water supply system to serve the communities in the area.
  • Ekiti State, mapping of 4 towns - Reid Crowther arranged for the necessary airphoto and ground control to enable the production and preparation of mapping and water main information for 4 towns.
Geographic Information Systems
Reid Crowther has been involved in GIS projects in Nigeria since it began the Land Related Information System (LRIS) Project in 1991. From this early start Reid Crowther has moved onto implement both simple and sophisticated GIS projects for Abuja and Lagos State. The Projects undertaken by Reid Crowther include the following:
  • LRIS Project for Lagos State - Feasibility Study
  • LRIS Project for Lagos State - Stage 2 Procurement of Hardware and Software
  • LRIS Project for Lagos State - Development and establishment of the LISSU Building
  • LRIS Project for Lagos State - 40 sq. km. Test area for implementation
  • FCT Water Board GIS System
  • Lagos State GIS System to Support revenue enhancement programs
These are large complicated projects needing significant expertise in the client organisations if they are to be successful, it would be unusual to see such projects in the smaller centres in Nigeria.
