Analyze and draw response

CloudingSoft — Mon, 16 May 2016 07:53:22 GMT

hello I have 2 files with json response service Vehicle Routing Problem, but not analyze this information and draw on the map:

Request URL to return the output routes: http://optimocamino.cloudingsoft.net/tasks/responses/output_routes.js

Request URL to return output orders: http://optimocamino.cloudingsoft.net/tasks/responses/output_orders.js

as it should draw a map from this data?

read this json file and loop through the features.

var saved = dojo.fromJson(data); esri/geometry/jsonUtils | API Reference | ArcGIS API for JavaScript

for each feature create a graphic

var graphic = new esri.Graphic(saved);

final push this graphic on a Graphic Layer.

GRAPHICLAYER.add(graphic);

Fabien,

Looking at your JSON data, I am not seeing anything resembling geometry. I see statistics for each vehicle like travel times and distances, but not a polyline geometry that would show the route taken. Without this geometry, you can't draw anything to the map. It doesn't look like the JSAPI has a Vehicle Routing Problem module. You must be doing these on the server. Be sure to include the geometry on your output to be able to draw it from your results.

Regards,

Tom

Hi I did so but I still can show the way

I could indicate please I'm wrong?

Fabien,

I modified your script to read the results and plot the route lines. You were on the right track. The results returned paths instead of a complete polyline that could be plotted. I created a polyline from each path. You can look at the results here:

Hello

in the example it indicates that they are 3 vehicles, as could distinguish colors such routes and put a marker at each stop?

on the other hand I have the "output order" http://optimocamino.cloudingsoft.net/tasks/responses/output_orders.js

what use me this information?

thank you very much!

Fabien,

I would add a UniqueValueRenderer. I have updated the previous sample to use a UniqueValueRenderer.

Hello Tom

on the other hand I have the "output order" http://optimocamino.cloudingsoft.net/tasks/responses/output_orders.js

I understand that here indicates the order of the stops corresponding to each route / vehicle, but do not tell me the coordinates.

as you could add this information to map?

thank you very much!

Fabien,

Without the coordinates for each stop, they cannot be placed on the map. I do see that the output orders have distances traveled and you could possibly split the polylines at each of those distances to approximate the stop location.

Tom

Hello Tom

when sending solve the problem, it also sends the coordinates of each stop and deposit so they should match the path.

I have been helpful!

Fabien,

Your original request may send the stop coordinates, but the results don't contain the stop data. The app you had posted only showed the results, not the request.

Tom

exactly, I have that data.

but right there I have another problem I just asked to give by termianda this question.

I would like to see him and give me your opinion: https://community.esri.com/thread/177550

Thank you.
