3D Relief Mapping for Coastal Resource ManagementTools
Relief mapping is an activity where 2D contour maps are transformed into three 3D maps covering the entire ridge to reef area through the stacking of boards. This turns the map into an ecosystem-based tool for coastal resource management.
The process of developing the map, usually involving students or community groups with
some basic knowledge of resource attributes, allows a candid discussion on the issues confronting resources and how activities in the uplands affect the coastal environment. This tool is very useful especially in remote areas with no access to electricity and where people may not be well-oriented with computers.
Local governments, local and international nongovernment organizations, and project officers can use the tool to facilitate discussions with the community about marine and terrestrial spatial planning and proposed management actions.
Local students may also get involved in the creation of the 3D maps. It is an enriching activity that promotes learning and appreciation of resources toward better stewardship. The local community can also participate after proper orientation on how to read contour maps.
After a resource mapping activity, the output is an overlay map of identified resources and anthropogenic stresses (human impact). The combination of this information and other available data into a single 3D map creates a clear picture of the current local fishery status. The map
adds value toward marine and terrestrial continuum spatial planning. Relief mapping also highlights potential overlaps in resource use. It can also help communities identify areas that need urgent protection.
