The following project variables relate to the Stream Data variable category. They refer to the attributes of imported stream lines. These project variables must all be prefixed with %StreamData. eg., %StreamData.Exists.
Exists |
Returns True if stream data exists, otherwise False |
True / False |
|
NumberOfStreams |
Number of stream segments |
integer |
|
StreamLine[i].NumberOfVertex |
Number of vertex in this stream segment 'i' |
integer |
|
StreamLine[i].Vertex[j].XCoordinate |
X co-ordinate of this vertex 'j' of this stream segment 'i' |
decimal |
|
StreamLine[i].Vertex[j].YCoordinate |
Y co-ordinate of this vertex 'j' of this stream segment 'i' |
decimal |
|
StreamLine[i].Vertex[j].Easting |
Easting of this vertex 'j' of this stream segment 'i' |
decimal |
user coordinate |
StreamLine[i].Vertex[j].Northing |
Northing of this vertex 'j' of this stream segment 'i' |
decimal |
user coordinate |
StreamLine[i].Vertex[j].Elevation |
Elevation of this vertex 'j' of this stream segment 'i' |
decimal |
m |
StreamLine[i].Vertex[j].InSubCatchment[k] |
Returns True if this vertex 'j' of this stream segment 'i' is within the subcatchment with ID value equal to 'k', otherwise False |
True / False |
|
StreamLine[i].Vertex[j].WithinCatchment |
Returns True if this vertex 'j' of this stream segment 'i' is within the catchment, otherwise False |
True / False |
