network analyst in flex

isti · September 12, 2013

Dear All,

I wanna share my concern about creating the application in flex. I wanna create the application of sea routing, then I utilize network analyst; the closest facility and new route facility. While creating the application for new route there is no problem appeared. Flex application to find the new route with the input data can works as well. But the problem is appeared when execute the closest facility, I already used the default parameter in ArcGIS 10.1, but It doesn't work. The parameters are same as the default but, in my application can not input the point as the facility and incident. the alert is --> No "facilities" found for "My Location" in "Incident" No Solution Found.

Then I check the way I publish the network analyst from arcGIS 10.1, and the parameter as the input in Flex there are no mistakes, but the application to create route still doesn't work. I really appreciate for the responses. Thanks

regards

check your data in network analyst in arcgis desktop, make sure you have good data, use the same function but in desktop software

no "facilities" found for "my location" error could be come from numerous problem

Thanks for the response,

In my ArcGIS desktop, the closest facility works. It can find the closest facility based on the incident location, but while I input in flex the alert is appeared. Then, how to make sure there is no mistake on my data. Because it works in arcGIS desktop.

Thanks.

maybe you should post your flex code snippet here , so we can examine it

I saw many good flex script for network analyst, have you try it,

Im not a coder,

    Description:
    This sample demonstrates how to work with ClosestFacilityTask.
    The ClosestFacilityTask is used to find the closest facilities around
    an input location. The ClosestFacilityParameters object is used to
    define how many facilities to find and various other properties,
    such as travel direction and cutoff.

    The closest facility solver measures the cost of traveling between incidents
    and facilities and determines which are nearest to one other.
    When finding closest facilities, you can specify how many to find and
    whether the direction of travel is toward or away from them.
    The closest facility solver displays the best routes between incidents
    and facilities, reports their travel costs, and returns driving directions.

Here are the script that I already used. I built that script in Adobe Flash Builder 4.5, and I still have this notice

--> No "facilities" found for "My Location" in "Incident" No Solution Found.

Is there any mistake in my script?

Thanks for the response..

You need to code your script so it wont broken. Use <> button. Paste your code inside box

isti · September 12, 2013

Those script are same as the default network analyst in arcgis for flex. I just modify the input map, and my network analyst service. But the difference is in my application can not solve the route.

hello sorry, I just edit your post to make it view-able but I think I miss to update this part :

var facilitiesSet:FeatureSet = new FeatureSet([]);
                var facility1:Graphic = new Graphic(new MapPoint(-13043098, 3856928, new SpatialReference(102100)), null, { Name: "Hyatt" });

could you please update it, so people can see the real script from you

sorry for this

Description:

This sample demonstrates how to work with ClosestFacilityTask.

The ClosestFacilityTask is used to find the closest facilities around

an input location. The ClosestFacilityParameters object is used to

define how many facilities to find and various other properties,

such as travel direction and cutoff.

The closest facility solver measures the cost of traveling between incidents

and facilities and determines which are nearest to one other.

When finding closest facilities, you can specify how many to find and

whether the direction of travel is toward or away from them.

The closest facility solver displays the best routes between incidents

and facilities, reports their travel costs, and returns driving directions.

This sample demonstrates how to work with ClosestFacilityTask.

The ClosestFacilityTask is used to find the closest facilities around

an input location. The ClosestFacilityParameters object is used to

define how many facilities to find and various other properties,

such as travel direction and cutoff.
