Measuring Tool - Changing the Default Units from Meters to Feet?

ipeebles

My data is in state plane coordinates. . the units are in feet, but the measuring tool comes in a meters by default.

Has anyone changed the default measuring units from meters to feet? I want to keep the lat and long coordinate, but want to expand the number of decimal places from 2 to 6.

Anyone have any suggestions?

Does anyone have any suggestions for this issue? All I need is:

1. Changing the default units from meters to feet by default. Right now a end user has to go in and change the units each time they need to make a measurement. . even when the measuring tool references the organizations geometry service.

2. Also the coordinates I need from 2 decimal places to 6. Example -97.123456 and 35.123456 rather than -97.12 and 35.12.

The out of the box sample for version 3.0 does not provide me the capability to make these changes. I was hoping this would be much more configurable.

Hi Ian,

For the Meters/Feet issue, the variable you need is set in the MeasureViewModel.cs file. Look near the top and you'll see the Linear and Areal default units (I've attached a screenshot). Change the LinearUnit = LengthUnits.UnitsFeet instead of LengthUnits.UnitMeters. Then compile the solution, remove the existing Measure tool from the Application Builder, and upload the newly compiled Xap file. You may need to refresh your Browser.

For the coordinates issue, you'll need to edit the MeasureView.xaml file. Find the following bits and change the StringFormat attribute. For example, where it says {0:n2\}, change the "n2" to "n5" or the desired number of digits after the decimal.

**Note - if you already have a version of the Measure Tool from ArcGIS Online, we've made a small update to it today, so please re-download it.


            <TextBlock
                Margin="5,5,0,0"
                Text="{Binding Path=Latitude, StringFormat=\{0:n2\}}"
                Visibility="{Binding Latitude,
                    Converter={StaticResource NotNullToVisibilityConverter}}"
                Grid.Row="1"
                Grid.Column="1"/>


            <TextBlock
                Margin="5,5,0,0"
                Text="{Binding Longitude, StringFormat=\{0:n2\}}"
                Visibility="{Binding Longitude,
                    Converter={StaticResource NotNullToVisibilityConverter}}"
                Grid.Row="2"
                Grid.Column="1"/>

Hope that helps,

Thanks Katy. The problem I am having is that I cannot seem to modify the add-in that comes with the latest viewer. Is there a way I can work with the add in alone? All I see is the .xap file.

KatherineDalton

Hi Ian,

You'll need to download the Measure Tool sample from ArcGIS Online. After you unzip the file, you'll see that it includes the full source code for the Measure tool, exactly as it is included in the Application. You'll need to make the edits as described in my earlier post, and then rebuild the solution. The resulting .xap file is what you will then load into the ArcGIS Viewer for Silverlight in the same manner as you would other add-ins.

Katy,

Thanks for all of your input. I downloaded the sample. . opened the solution file and made the changes you suggested. The Add-ins part of the project did not open. I then did a debug and a rebuild, but the problem is that the .xap file located outside of the MeasureTool.Addins and MeasureTool.Web did not update to today's date. I even tried to open both folders in Visual studio and did a rebuild, but same result. Any ideas? See the screenshot below.

Hi Ian:

The xap in the root of the zip file will not be updated when you compile the source. Rather, you'll need to copy the add-in's xap file from the output location under the Source Code folder (i.e. Source Code\MeasureTool\MeasureTool.AddIns\Bin). The xap should be contained in a Release or Debug folder in that location, depending on whether you have compiled the add-in using the Debug or Release configuration.

However, if the MeasureTool.AddIns project is failing to load when you open the project in Visual Studio, then you probably lack some pre-requisites for developing Viewer add-ins. You'll need to install the Microsoft Silverlight 5 Tools for Visual Studio 2010 and the latest Silverlight Toolkit.

Rich,

I did do the upgrades you suggested. Below are screenshots on where I am at. I opened the AddIn in Visual Studio, then did a rebuild and save. Still not getting the .XAP file updated though it was moved to the debug folder. The only changes I have made were to the MeasureViewModel.cs (changing the units) and the MeasureView.xaml (expanding digits past the decimal) files. Hopefully, I am getting closer. To do appreciate the input.

If the xap file is present in the Debug folder, then it is compiling - that xap file contains your changes. Now that you have it, you need to replace the version in the Application Builder with the new version. To do this:

Open the Application Builder
Click the Settings link (upper right)
Click the Add-Ins tab
Next to MeasureTool.AddIns, click the delete button. Confirm the deletion when prompted.
Clear your browser cache. If you are using Internet Explorer, the most reliable way is to open a command prompt and input the command "rundll32.exe inetcpl.cpl,ClearMyTracksByProcess 8"
Refresh the browser page
Navigate to Settings --> Add-Ins again
Click the "Upload Add-Ins" button
Browse to your compiled version of the MeasureTool.Addins.xap file. Make sure you select the one under the Debug folder.
Create a new app and add the Measure Tool to it. When you try it out, you should see your changes.

That should do it for you.

Rich,

I think everything is place and I removed the tool and cleared the cache, then re-added the add-in, but getting the same results. The date of the .XAP file in the Debug folder is 10/12/2012 even after the rebuild and save. If the .XAP rebuilt shouldn't it be 10/30/2012? In terms of my environment I have the ArcGIS Silverlight API 3.0, the ArcGIS Extensibility SDK 3.0, The ArcGIS Silverlight Viewer 3.0, Microsoft Silverlight 5 SDK and Microsoft Silverlight Tools for Visual Studio 2010. I initially modified the two files I mentioned above using Notepad++ since they were simple changes.

ipeebles

Well I actually got this working! I figured out I had to install the Microsoft Expression Blend Software Development Kit (installed the BETA of Silverlight 5) on my machine.

What version is ESRI using?

Microsoft Expression Blend Software Development Kit (SDK) for Silverlight 4

I assume this version would work as well?

By installing this SDK, my errors were resolved. I then did a rebuild and save. Next I removed the add-in from the viewer. . cleared the internet cache, then I was able to add in the updated add in and it worked.

KatherineDalton

Hi Ian,

I'm so glad to hear it worked! When we moved to the ArcGIS API for Silverlight 3.0, we also moved to Silverlight 5, therefore the requirements for developing add-ins are as follows:

    Microsoft Visual Studio 2010 or Microsoft Visual Web Developer 2010 Express.
    ArcGIS API for Microsoft Silverlight 3.0.
    Microsoft Expression Blend Preview for Silverlight 5.
    Microsoft Silverlight 5 Tools for Visual Studio 2010 SP1
    Microsoft Silverlight Toolkit

Could someone please upload a .XAP of a measure tool with Feet as the default measurement?

This add-in has the measuring units defaulted to feet. I worked on this file back in October. Let me know if this works.

Thank you so much Ian. That works perfectly! You should upload it to the resource center.
To make it work I deleted my old measure tool add-in and added yours. Then I deleted the internet cache and reopened the map and it worked.

TomMagdaleno

Ian,

Did you even update to a newer version of Silverlight viewer and find that it did not work anymore? I went from 3.0 to 3.3 and the measure tool no longer works. I am trying to modify it in Visual Studio but it says my Silverlight version is not high enough. I'm at version 4. If I download 5 it tells me it is already installed. Long story short, you wouldn't happen to have a .xap file that works with 3.3 would you?
