Gpsmapedit polyline nodes
My experience is that GPSmapEdit is correct, so turn off the stop on error option of cgpsmapper and just do your error checking in GPSmapEdit. If you run cgpsmapper with error reporting, it will report a lot of "Node too Close" errors that GPSmapEdit doesn't show. It can also make malformed polygons really ugly, so I don't slice those. Slicing non-routable objects greatly reduces compile time.
#GPSMAPEDIT POLYLINE NODES VERIFICATION#
The second verification may show some errors with unspecified line types, which GPSmapEdit interprets to be roads. I'll then "ADD" or paste the routable elements onto this map, and verify the combined map. I'll combine all my topo, hydro, and wooded areas, generalize and slice them, and save the map. To keep things simple, I usually keep my routable data on a separate map from non-routable, and only verify the routable map after I've generated a routing graph. If any of GPSFileDepots master map makers familiar with this process would be so kind as to offer advice, i would be very grateful!ĭepending on your Verify Map options the Verify Map procedure will check lots of non-routing issues like malformed polygons. Using the Edit Nodes mode, right click to Split Polyline where the water. Generate Routing Graph Using coinciding nodes of Polylines. I assume I must run the 'Routing Graph Generator' after any map edits for the map to be exported with complete and accurate routing information. Using GPSMapEdit, create closed polylines from the contour lines in each file. maps using GPSMapEdit and MapRoute/cGPSMapper (see Sources at the end of this guide. Nodes occur when the end node of a feature connects to multiple end nodes. For example, a long road segment may have been divided into two features. They often indicate that the two features can be merged. Why do all these errors reappear after running the 'Routing Graph Generator' again? I have not changed any data in the map between. Pseudo nodes occur when the end node on a feature connects to another end node with no other nodes present. However, If I re-run the 'Tools > Generate Routing Graph' function, and then re-run the map verification, I will again be presented with hundreds of errors, many of which appear to be duplicates from the previous verification.Īfter about the third time around, I did not save the new *.mp mapset, and undid ('ctrl-Z') the new routing graph. I can then save the map (*.mp) as is, and run the map verification at will, returning zero errors each time. I will get a list of several hundred errors, and I will spend hours correcting each error until the 'Verify Map' process no longer returns a single error. I will save my map in current configuration (*.mp) and select 'Tools > Verify Map.'. Recently, I have started to play with adding routing information to my maps using GPSMapEdit:
