I am trying to get the distance between the points in two datasets. For this I have created two point feature shapefiles using the corresponding two datasets. Now, to get the distance between the points, I have used the point distance tool under Analysis Tools>Proximity Analysis. However, for some reason the process is failing is failing. I have defined the coordinate system for the point features as a projected coordinated system (UTM NAD 1983 17N). The specific error was 999999 which was error in executing the function. Can someone please suggest a solution for this issue. PS: There is no specific sub forum for Analysis tools. As such, I have posted my query under this section.

Thanks a lot for your reply Jay. I was trying to create this dataset that you have mentioned. However, I have found that there is a tool available to do exactly this. I am sure you know about the ET Geowizards extension. In the ET Geowizards under the Point Functions there is a feature called Station Points. This tool creates points at fixed intervals along the routes (or for that matter along any polyline). This feature is free to use as well.

The output of that Create Routes tool should have measures unless the length field does not have any informaiton. Open the attribute table of the newly create feature. It should list "Polyline M" in the Shape column. If it only says "Polyline" then the tool was not executed properly. Jay Sandhu The shape column corresponding to the new routes table has Polyline M. It has a total of 3 columns as shown below. FID Shape Name As you can see, there is no column which gives the length of the route. Is this how it is supposed to be?

Following up, I have created another route layer using the create routes tool in linear referencing with the measure Source as Length. The help section you have posted suggested that the output route layer will have the measure M values. However, the routes output I have got does not contain any M values. Does this indicate some error ?

Instead of creating the event layer isn't there any other way to get the intermediate points along a route? For example, are there any polyline to point conversion or split polyline tools that can be used to solve this issue.

Thanks for the suggestion and sorry for the late response. Will this method work if my routes are calculated based on shortest time path. I have used the roadway length and the posted speedlimit to come up with the travel time along the link. Then, I have used this Travel_Time attribute to build the network dataset and compute the shortest route. Subsequently, I have created a shape file from the routes layer and computed the length attribute in the routes layer. Now can I use this layer to create the route events layer?

Thanks for the reply Jay. I have downloaded the add-in and have worked with it to generate the feature information. The traversal add-in generates the Junction points along the generated routes. However, I did not quite understand as to how the Junctions were generated along a route. It appears that the total number of junction points generated for different routes are different. Did the add-in generate the junction points based on the network features? Please let me know about this. Further, this tool may not provide the answer to my question. I was not looking to identify the features along the route. What I actually want is the location coordinates along the route at specific intervals. For example, for a given route between an O-D pair, I want the location coordinates along it at 50 feet intervals. In other words, I would like to break the route into 50 feet segments and then record the coordinate(s) at the end of each segment. Is this possible?

Hello everyone, I have created the shortest routes (in length) between several O-D pairs. Now, my question is, can I identify the discrete intermediate locations along the route. I need the location coordinates for the intermediate locations along the route. Is this possible?

Hi Michelle, First of all, sorry that I am unable to answer your question. However, I myself have a question for you. I am using the 201 NAVTEQ Quarter 4 NAVSTREETS data to do a similar kind of analysis where I am trying to get the number of intersections (with 4+ links, 4 links, 3 links or just 1 link) in a circular buffer. There is a particular attribute in the NAVSTREETS data which will allow us to identify the nodes which correspond to an intersection. But the problem with this is, if it is a 4 link node, there will be 4 point objects overlaying one another. Is there a way to identify these different intersections and separate them (like 4 link intersection point, 3 link intersection point etc) based on the number of overlaying points?
