I'm trying to use the dissolve network tool to dissolvle lines in a SHP file where all streets have a directional heading applied to them (start point to end point). But I simply can't get "Dissolve Network" to work. Here's what I'm doing:
- Right clicking on the supplied SHP file (see attachment) in Catalog -> New Network Dataset - Leaving all settings in the New Network Dataset Wizzard default (tried other settings as well but it didn't help for me). - Message "New Network Dataset has been created. Would you like to build it now?" - Yes - Message "Do you also want to show all feature classes that participate?" - Yes - After that the new network is created and visible. - Catalog -> System Toolboxes -> Network Analyst Tools -> Network Dataset -> Dissolve Network - Using the pulldown menu to select recently created "tester.nd" as input network dataset - That's where I'm getting the following error message: "ERROR 030070 Invalid network dataset type."
I spend a few hours browsing the forums, reading through the help files supplied by ArcGis but I couldn't find out what's wrong with my input file. Any ideas would be highly appreciated.
Dissolve doesn't honor the digitized direction of your edges but it does guarantee that the resulting digitized directions are consistent with the attributes. What this means is that dissolve will flip edges but it will change the oneway attribute from a 'F' to a 'T' because not doing so would result in inaccurate attributes. Depending on what other attributes you have you may be able to:
Ah, makes sense! So I was misguided believing that changing the oneway attribute to a boolean type would solve it. In fact it removed the "F" and "T" options. The result looks great and exactly how I wanted it. Thank you both very much!
