C5.070 Report of converter webservice that transforms point occurrence data to distribution data (report 1)

This report provides a summary of the procedures and steps to follow using converter webservices for transforming point occurrence data to distribution data.

Point data to regional distribution - Priorities in programming efforts should thus be concentrated on a set of known end-user needs in the domain of taxonomy related work, for practical purposes. Based on previously conducted surveys and reports following services have been selected as a priority to be used by taxonomists or users of taxonomic information:

Logical aggregation - qualitative generalization to a higher logical aggregation level. EDIT mapViewer currently prints user data based on Genus information. A logical aggregation procedure is thus followed by the system already. Any kind of logical aggregation can be applied if user has the necessary information, but the range of possibilities is so high that requires a very flexible interface and programming.

Spatial reference – already aggregated point data (aggregation might be at any level) should be referred to an area. In the area the points are referred to might be existent, such as administrative units, statistical divisions, climate types, geographical units, etc. or user-defined such as regular grids of squares based on different coordinate systems (UTM, AFE, local grids) or other regular grids such as triangles, hexagons, etc.(polygons) (*).
