African Geomatics
Mapping and GIS Services
A Geographic Information System (GIS) is used to capture, store, manage, analyse and display spatial data linked to locations on the Earth's surface. GIS combines information from different sources to support mapping, planning and spatial analysis. A sound understanding of geodetic datums and map projections is essential for ensuring that spatial data from different sources aligns correctly.
African Geomatics uses GIS to collect, manage and analyse spatial data. Our applications include maintaining spatial databases, querying and checking data, surface modelling and preparing information for mapping and surveying projects. GIS is also an important tool for project planning and logistics, allowing spatial information to be organised and used efficiently.
Digital mapping combines data from different sources to create maps for specific purposes. Sources may include satellite imagery, orthophotos from the Surveyor-General's Office, existing maps and survey data.
We can prepare customised maps for farms, showing features such as boundaries, camps, fences, roads, water points and other infrastructure. Digital maps can also be produced for applications such as hiking trails, park routes and general land management.

Aerial mapping uses photographs captured by an aircraft or unmanned aerial vehicle (UAV), together with photogrammetric processing, to produce detailed maps and spatial data. Compared with mapping based on existing imagery, UAV surveys can provide more recent and higher-resolution information for smaller areas. The achievable accuracy depends on factors such as image quality, ground sampling distance, ground control and processing methods.
Applications include preparing base maps for road design and intersections, documenting existing buildings, planning extensions and providing survey information for developments such as sectional title schemes. For more information, see UAV Surveys.

Digitizing converts features shown on paper maps, plans, scanned documents or images into digital spatial data. The resulting data can be stored in a GIS, used to create digital maps and incorporated into spatial analysis.
African Geomatics digitizes township layouts from General Plans filed with the Surveyor-General's Office. This information is used internally for surveying and planning purposes, and digitizing services can also be provided on request.
