Get distance between two points in GIS

Hello guys,

I created a map in Flexsim that has some cities, each city is represented by a Point.

Now I need, through Flexscript, to get the Driving Roads distance between two of these cities or to get a Route object so that I can access its properties. Is there any way I can do it in the source code or this distance is only showed in Route Properties?


Thanks for your attention.

treenode point1 = Model.find("GISNavigator/Point1");
treenode point2 = Model.find("GISNavigator/Point2");
double distance = function_s(point1, "getDistance", point2);

Thanks for your answer.

I found this in another topic and already tried it, but unfortunatelly I am getting an exception and still don't know how to solve it.


This is the exception

exception: Exception caught in TreeNode::callMemberFunction() c++/dll execution. Throwing... MAIN:/project/library/GIS/Point>behaviour/eventfunctions/getDistance c: /GISNavigator/SAO PAULO thisClass: MAIN:/project/library/GIS/Point
exception: FlexScript exception: MODEL:/Tools/GUIs/GUI 1/Mostrar Cluster>OnPress c: MODEL:/Tools/GUIs/GUI 1/Mostrar Cluster i: MAIN:/project/model


The main part of my code is as follows:

Object navigator = model().find("GISNavigator");
Array vetor = navigator.subnodes.toArray();
Object point1 = navigator.find(cidade);

for(int i = 1; i <= vetor.length; i++){
            if(vetor[i].getProperty("Latitude") <= lat_max && vetor[i].getProperty("Latitude") >= lat_min && vetor[i].getProperty("Longitude") >= long_min && vetor[i].getProperty("Longitude") <= long_max){
                double distance = function_s(point1, "getDistance", vetor[i]);
                vetor[i].color = Color.blue;
                cluster.append(vetor[i]);               
          }
}


I would be thankful if you could help me one more time.

I can't tell you what's wrong from just an incomplete code snippet.

Post your model with replication steps.

Oh, sure.

My model is still very messy, it began as a test and started growing, I still need to rewrite some codes but it is possible to test where the problem is happening.

All the maps and points are already plotted and all you have to do is open the GUI and click on "Mostrar Cluster". It will automatically get the cities in GlobalTable2, use one by one to create a cluster of cities and find the distance among them, the model may freeze a little but it will work.

Because the map is plotted, the file is too large for upload, so I put it on Google Drive on this link https://drive.google.com/file/d/1pC-mayaHMW-FRsYAMXm_BPv9AGG_cYkX/view?usp=sharing


Thank you very much for tour help again
