Member Function Documentation

bool vtVegLayer::AddElementsFromSHP_Points ( const wxString &  filename,
const vtProjection &  proj,
VegPointOptions &  opt 
)

Extract point data from a SHP/DBF file and intepret it as a vegetation layer. This produces a set of vegetation instances.

The 'opt' parameter contains a description of how the fields in the imported file are to be interpreted.

bool vtVegLayer::AddElementsFromSHP_Polys ( const wxString &  filename,
const vtProjection &  proj,
int  iField,
VegImportFieldType  datatype 
)

Extract data from a SHP/DBF file and intepret it as a vegetation layer. This produces a single-valued polygonal coverage.

'iField' is the index of the field from which to pull the single value. 'datatype' is either 0, 1, or 2 for whether the indicated field should be intepreted as a density value (double), the name of a biotype (string), or the ID of a biotype (int).
