Validation & Verification

Geographic Information Systems and their associated applications can be applied at all levels of planning, design, operations and maintenance. One of the less documented applications is that of monitoring, validation and verification of project progress. This can include the reporting of significant changes in an area such as the area of cultivation under irrigation in a catchment area or the number of houses built in a new development project.

In these applications, GISc tools such as remote sensing and image interpretation can be used to monitor and document progress of a project and report on changes in land use or land cover across a large area. A simple example would be quantifying the number of new houses built in a development, where the actual number of structures can be mapped and classified and this information used in support of project management and reporting. The process can be repeated at a regular basis based on the reporting and monitoring requirements.

Other examples would include documenting the length of roads tarred or built, the area of new irrigation or the area of urban development or densification which can be seen on imagery.

Having the abilities to independently and consistently monitor and map these changes provides a cost effective tool to monitor activities. These mapping exercised can be repeated in the future to provide consistent reporting over the life-time of a project. One of the problems with large multidisciplinary projects, where many stakeholders are focused on their own specific deliverables, is trying to quantify the project holistically and to provide adequate reporting to assist with the allocation of resources and funding.

Examples of projects undertaken in this environment include:

Water Use Licences & Catchment Management
It is crucial to understand the agricultural water usage in our water scarce country, where surface water and ground water use needs to be monitored and managed on a regular basis to ensure compliance and remote sensing can play a vital role here.

Water use validation and verification projects are being undertaken across South Africa to fully understand the impacts and implications of water use licensing. GEOTERRAIMAGE has developed skills and mapping methodologies in support of these processes and has the capacity to provide input into these projects through the optimal use of remote sensing technologies and expertise.

Remote sensing can therefore ensure the accurate monitoring of historical and current water use and provide input into the understanding of water use in a catchment or water management area.

Agriculture & rural development projects
GEOTERRAIMAGE has been extensively involved in mapping agricultural related information and this has included the monitoring of rural development projects and their outcomes.

In lieu of the South African Governments focus on the upliftment of the rural communities, GEOTERRAIMAGE conducted a survey of the extent of cultivation in traditional tribal areas to understand the food security implications of subsistence agriculture and the role it plays in the sustainability of these communities. The remote sensing based surveys can assist to quantify the extent of cultivation on a year-by-year basis and this can be qualified through in-field surveys. The ability to access critical issues such as the extent of cultivation can provide timeous data in support of government decision making and policy specifically related to food security and poverty alleviated in these rural areas.

With respect to commercial agriculture and the production of staple food products, GEOTERRAIMAGE is a key member of the Crop Estimates Consortium which conducts the Producer Independent Crop Estimates System (PICES) survey to access the area under cultivation. This process is crucial to food security policymaking and furthermore contributes to the SASEX wheat and maize futures pricing.

This survey is furthermore complimented on a yearly basis by a comprehensive crop typing exercise in one of the maize producing provinces to ensure that the Government has a clear understanding of present agricultural practices. This use of remote sensing in support of policy development and decision making makes it a critical input at all levels (operational, tactical and strategic).
