Guest mzellmer Posted June 12, 2006 Share Posted June 12, 2006 I have a rather complicated set of faults that are in MapInfo. All I seem to be able to get out of MapInfo are the centroid and endpoint coordinates. Does any one know how to get the polyline segment coordinates out of MapInfo? I also have the use of ArcView 9.x if someone know how to do it with that program. Thanks Link to comment Share on other sites More sharing options...
Mitch Posted June 13, 2006 Share Posted June 13, 2006 Can you provide an example of this format? Link to comment Share on other sites More sharing options...
Guest mzellmer Posted June 14, 2006 Share Posted June 14, 2006 Can you provide an example of this format? <{POST_SNAPBACK}> I've attached an image which is the best way to explain this. All the dots are nodes. I've highlighted the polyline that the info is being displayed for. The straight polylines aren't a problem, but the curved ones are. All Map info gives is the total length of the line, how many segments, the number of sections, the endpoint coordinates of the polyline and the centroid coordinates. I need to get the node locations in order to accurately draw these polylines in Rockworks. Here is an example of what MapInfo spits out in it's tab file. These coordinates are centroid locations of the entire polyline.

Mitch Posted June 14, 2006 Share Posted June 14, 2006 I may be missing something but these look like the vertices of a polyline. You can edit it very simply to a RockWorks AGL Polygon format which can be used to create a graphical line in RockPlot2D and also for creating grids.
