How can the mid-point of a polyline be calculated using the
geoprocessing framework, eg in a Python script? The
polyline.centroid property returns The true centroid if it is
within or on the feature; otherwise, the label point is
returned. The centroid is rarely located on non-straight lines,
which is useless for my purposes. The Feature Vertices to Points
tool has a midpoint option but this requires ArcInfo, which I
don't currently have. An option could be to add measures to the
polylines and create a route event 50% along the line. Another
workaround is to use the Calculate Geometry option in ArcMap,
but ideally I need to automate this process in a script. Any
better/faster suggestions? Thanks [EDIT] I'm limited to ArcGIS
10.0 for the moment.
