| Jun 23, 2011 at 13:44 | comment | added | Kev84 | Thanks Kirk, So i got rid of project, and just assigned spatial reference, also called snaptospatialreference. It didn't help though. It still cannot find the feature =( | |

| Jun 18, 2011 at 4:03 | comment | added | Jakub Sisak GeoGraphics | The "Topological Operator" approach could work but it will not be very efficient. I don't do C# (just VB) but I just don't understand what is going on in your code? Are you making a polyline from the incoming point and only adding one point? Why project the polyline? Does the Spatial Reference of the two geomtries differ? You should maybe debug this on features that share the same spatial reference first. Also, you might want to use iTopologicalOperator5 instead since it supersedes the version you are using. | |

| Jun 18, 2011 at 0:29 | comment | added | mkennedy | Do you want to know if the point lies on (in) the polyline, but it doesn't have to fall exactly on one of the polyline's vertices? A note based on your other question, which implies that the data may be projected on-the-fly. You can get different answers, in different coordinate systems, but more likely with 'long' lines. | |
