MGRS Widget for Flex Viewer

MarcGraham — Thu, 16 Feb 2012 04:37:06 GMT

Hi,

Has anyone got a compiled widget for the Flex Viewer that returns the current cursor location as an MGRS grid?

It would be great if it worked with multiple coordinate systems.

regards,

Marc

Marc,

Have you had a look at the widgets posted by Kerry Coffin:

'>http://www.arcgis.com/rc/item.html?id=56d4d2ed5d474eb4b8e29973d2376652
http://www.arcgis.com/rc/item.html?id=3192d6f61c9f4baaa34c9789d00d5b95

I found these really useful and have combined the code into the coordinate widget to provide the same functionality that is provided in these widgets. (i.e. show MGRS location on mouse move, turn MGRS grid and geographic grid on/off and zoom to mgrs) in a banner along the bottom of the application.

Regards

Tony

Hi Tony,

That is exactly what I am after. However, It would be brilliant if someone could upload a compiled version for Flex Viewer 2.5. I don't have any way to build that widget. Is there any chance you could compile your modified coordinate widget and upload that?

That would be extremely awesome.

Cheers,

Marc

Marc,

Please find attached zip file that includes compiled versions of the MGRS widget and my updated coordinate widget. They are both compiled to work with geographics (EPSG 4326). Hopefully they will work without the rest of the project as they do ultilise two libraries that do not seem to be in the compiled version of the application. Unfortunately if you do require them to work with a different projection you will need to contact Kerry Coffin to provide different libraries.

The coordinate widget is added into the UI area in your main config file:

<widget url="widgets/Coordinate/CoordinateWidget.swf" config="widgets/Coordinate/CoordinateWidget.xml" left="0" bottom="0"/>

Then set bottom="25" as a property of your map element.

The MGRS widget gets added in the same way as other widgets.

Hope these are of some use

Regards

Tony

Those tools are great. I have spun up a quick test site in WGS84 and they work perfectly. I really like how the mgrs tool returns a grid square if you enter less than ten figures, genius. ESRI need to implement that into ArcGIS Desktop for 10.1. One small improvement would be to be able to right click and copy the grid to the clipboard, that would make them even awesomer!

Only thing is our web maps are all running in WGS1984 Web Mercator Auxilliary Sphere . Kerry Coffin, if you are out there, are you able to help?

Cheers!

Marc,

I have implemented this functionality by adapting the coordinate menu widget by Andrew Timmins:

http://www.arcgis.com/home/item.html?id=edd4a2b7c722493a8b08f53eaa131e1e

Again place the widget in your UI elements in the main config:

<widget url="widgets/CoordinateMenu/CoordinateMenuWidget.swf" config="widgets/CoordinateMenu/CoordinateMenuWidget.xml" top="20" left="8"/>

Regards

Tony

Tony,

The combination of the two tools you have supplied me are Exactly what I am after.

Except for the fact they only work on a WGS84 webmap.

If anybody could adapt these to work with a WGS1984 Web Mercator Auxilliary Sphere map I would be eternally grateful.

Thanks heaps!

Marc

Hi Tony,

Is there any chance you could incorporate the Web Mercator version of Kerry's widgets as found here:

http://www.arcgis.com/home/item.html?id=56d4d2ed5d474eb4b8e29973d2376652

If you could help me on this it would be awesome.

Cheers,

Thanks so much Tony. I really appreciate you taking your time to help myself, and everybody else who uses USNG/MGRS. I think that this will prove to be very popular.

However, there appears to be a small bug in the Coordinate Widget, it seems to return an incorrect grid. The MGRS Widget works correctly.

Also, do you know if there is a way to clear the red square once you have entered a grid using the MGRS Widget?

Thanks again,

Marc

Marc,

Sorry didnt realise that the clear button was not in the MGRS tool, new .swf file with it included.

I'm not sure what is happening with the coordinate tool not showing the right grid in your application, as I have checked my side and it appears ok. The grid given in the coordinate widget matches that in the MGRS widget and they are both the same as the base mapping in ArcMap.

Just to be sure are you using WGS 1984 Web Mercator as your projection in ArcMap, it should read as srs 102113 in the rest end point. Other than that I'm lost,

Regards

Anthony

Thanks for adding that clear button, that's brilliant.

I think that I wasn't clear in my last message. The MGRS Grid readout in the coordinate bar is correct, as are the lat/long, map x,y etc. It is the Go To MGRS box in the bottom right that is giving me issues. No matter what grid I enter it sends me to lat/long 0,0.

My map is in WKID 102100 (3857) which as far as I can tell is equivalent to 10213 as discussed here:

http://forums.arcgis.com/threads/8762-WGS-1984-Web-Mercator-(Auxiliary-Sphere)-WKID-102100

I don't s'pose there is any chance you could adapt that right click/copy widget to this format as well.

Thanks heaps.

Marc

Marc,

Just checked the code and realised that I had an error, attached is new zip file for the coordinate widget.

Not sure what you mean by 'adapt the right click/copy widget to this format as well' this should be included in the zip file posted 03-01-2012, 01:28 AM. The config file allows you to set any coordinate system.

Anthony

What I meant was, the right click - copy coordinate menu tool only works for MGRS when the map is in WGS84, not Web Mercator, the same as the other tools before you modified them.

Currently, you can set output coordinate systems in the xml file and right click, copy these to the clipboard, this works great. But if you try and right click, copy the MGRS option you added nothing gets copied. The tool works great in WGS84 maps though.

Thanks again.

Marc,

I have looked at it on my system and the right click copy MGRS is working as it should. Just in case we have had a mix up of files along the way somewhere I have attached a zip file containing the 3 widgets (coordinate, coordinatemenu & MGRS) that are all working on my system.

Anthony

Re: MGRS Widget for Flex Viewer

MarcGraham — Wed, 07 Mar 2012 11:41:27 GMT

Excellent. I don't know if I missed a download, or what happened, but I have implemented the coordinate menu widget from that last upload you provided and the copy MGRS to clipboard now works a treat.

Thank you so much for your help.

Are you interested in developing these tools further? I am sure that there is more functionality people could use, or tweaks to the config files to make them more user friendly to set up.

Cheers,

Marc

Anthony,

I am getting an Error Code #2036 in the MapManager popup. I am using FV2.5. BTW - The Coordinate Widget and CoordinateMenu Widgets are awesome. I don't fully understand how they can be configured but I've been looking for this functionality for a while so great work.

I did notice that the MGRS longitudinal labels are cut off at the bottom of my map. Can the placement be configured?[ATTACH=CONFIG]12505[/ATTACH] It appears that the grey footer banner is covering up the labels.

How can I make the MGRS grid be turned on by default?

Thanks.

Will,

Error Code #2036 usually means that a path to one of your widgets is incorrect in your config file, i think flex is case sensitive so just check to make sure everything is alright. Also the two coordinate widgets are added in the UI area of your config file not the normal widget area.

As for the labels being cut off by the banner set an attribute of bottom="25" in the map element.

I will look into setting an option of have the grid enabled or disabled in the config file.

Regards

Anthony

Will,

Find attached zip file containing coordinate widget with two extra values in the config xml that allow the Grids (MGRS and Graticule) to be set to true or false.
