PGIS practitioners use a range of low- and high-tech geographic information technologies for acquisition, validation, analysis, representation and sharing of geo-spatial information.
This Unit reviews the main factors that influence the choice of one method over another or the combination of more than one method. Factors include the purpose behind the initiative, the resources available and the institutional setting or environment.
The approach which map makers may wish to take when embarking upon a participatory mapping initiative will vary significantly depending on the purpose of the mapping initiative. This purpose will be influenced by the audience who views the maps upon completion and makes decisions surrounding their content. Maps may be made exclusively for internal community use or (more commonly) they may be used to communicate local land-related knowledge to outsiders.
