Is anyone building a USNG Geocode widget for WebApp Builder?

PaulDoherty2

It seems there is no way to provide a web map or web mapping application where someone can simply type in US National Grid coordinates and zoom to that location on the map.

Has anyone built this yet or is it in the pipeline at Esri?

I am hoping there will be a geocoding service stood up or a custom widget built so we can provide this service to map users.

*IMPORTANT* See my note below about using a USNG Geocoder as a Utility across your entire ArcGIS Online Account.

Configure utility services—ArcGIS Online Help | ArcGIS

Ok some options.

If you have the option to create custom deployment (host-your-own)

Use Tim's widget it is awesome. Location Widget

If you are using the hosted WebApp Builder only

You can use the Search widget with a USNG / MGRS geocoding service eg MGRS (GeocodeServer)
Don't forget the Coordinate widget can be configured with USNG display and reverse geocoder
The NGA_US_National_Grid (MapServer) map service does an OK job of displaying USNG on the map, but it should be used in conjunction with spatially explicit tools like the ones listed above.

Please keep the discussion going and if anyone has other ideas add to this thread.

UPDATE - The FEMA Geocoder seems to be disabled or secured. For now I am going to use this URL MGRS (GeocodeServer).

Also, if you have administrator privileges I suggest simply adding a USNG Geocoder as a Utility Service.

My Organization --> scroll down to Utility Services --> Geocoding --> ADD GEOCODER

Then all of your web maps and apps will have this as an option.

Tim -

I do not know of any that are public. But there are 100m layer packages available on ArcGIS online and in a pinch I have published these as feature services.

Let me know if you find any.

For an all-javascript solution that converts between USNG and latlng, see the work by Larry Moore. Others worked on the code before Larry and they are credited in the js file.

Start here: USNG

Go to Larry's app and look at the source.

usng.js is near the bottom of the source listing.

I am using that code for point conversions in my Gmap4.

Here is a 100m USNG grid with the map centered near the Seattle space needle.

Paul,

do you know of any feature service that includes 10m or is 100m as close as it can get at this moment?

It works really well!

Paul,

I use the following from ESRI MGRS (GeocodeServer)

Tim

PaulDoherty2

Thanks Tim Witt - nice simple interface.

I was also able to add USNG to the Search widget using this geocoding service

http://arcgis-emergencymanagement-2057568539.us-east-1.elb.amazonaws.com/arcgis/rest/services/Locator/MGRS/GeocodeServer

But this may just be a sample service and I am not sure of the source.
