Batch Geocoder Widget for Flexviewer 2.x

ReneRubalcava

We recently had a need to build a Batch Geocoder tool that we could use to verify some addresses against our internal GeocodeServer service. This started as an AIR application I built in my spare time, but decided to modify it to work with Flexviewer. It's a tool we might use in our internal Flexviewer app, and I thought others might find a use for it.

It will let you upload a dbf file of addresses, geocode them, give you the closest address found and the score, then export those results to an Excel file.

I'd also love to see an update for this widget. I got it to work perfectly in 3.5, but the input still requires a *.dbf file, and as many of you already know, MS Office no longer supports dbf files in excel. So, the input file selection process would have to have the option to accept xls, xlsx, csv or txt. Someone want to get paid to do it? 😉

Is there an update of this widget for the latest release? v3.6?

Hello Renee,
I can add the widget to a flex site, compile it and do not get any errors. However, when I select a .dbf file and click "Open" nothing happens. I've got all the libraries added according to the README file. I am using Flex Viewer 2.5 and Flex 4.5.0.
Thank you,

Sorry for the delay.
I've updated the source code this morning.

You can now define the output Spatial Reference wkid for your Locator service so that it will match your map services.

I tested it briefly without issue, but if anything does not work please let me know.
Thanks.

Good Morning Rene,

Still no luck. Definately an issue with the projection. If I use the ESRI geocoder, it stays within the correct geographic location although I don't see any points mapped. All the addresses geocode correctly though.

Don't spend any more time on this for now. I am going to create new locators and services and go from there. I will let you know.

Thanks !!

Nestor.

I'll look over the code, but there is a section when I initialize the locator, that I set the output Spatial Reference to geographic. I've been meaning to add that as an xml option.

Good Morning Rene,

The change from Address to Street worked. I'm using a composite locator which I will add the Address field to map as well. Thanks.

Now it gets strange. First, the results come up but the background of the box turns white and the text does as well. I can mouse over the text and see it.

Next, the results take me to some extreme northing and easting outside my geographic boundary and no points are plotted. My locators are using projected coordinates instead of geographic although I am not having any issues with other addressing widgets.

Your thoughts?

Nestor.

I checked the source and I don't block geocoding if there is no city/zip, but depending on the Locator service you are using, you may have to change this in the source code.

widgets.BatchGeocoder.helpers

/**
 * Will parse the item passed to this class and prepare it for
 * use with ArcGIS Server geocoder.
 * @param item
 * @return 
 */
protected function buildAddressObject(item:Object):Object
{
 var address:String = "";
 var city:String = "";
 var state:String = "";
 var zip:String = "";
 var country:String = "USA";
 
 if (_addressField.length > 0)
  address = item[_addressField];
 if (_cityField.length > 0)
  city = item[_cityField];
 if (_stateField.length > 0)
  _stateField = item[_stateField];
 if (_zipField.length > 0)
  zip = item[_zipField];
 if (_countryField.length > 0)
  country = item[_countryField];
 
 // You may need to modify these fields to work with your
 // particular locator service
 return {
   Address:address,
   City:city,
   State:state,
   Zip:zip,
   Country:country
  };
}

That is the address object that gets created when you map the fields from your dbf. You may need to change Address to Street. You may even be able to eliminate all fields except for address in your case.

I test against this geocodeserver.

I'll check over source when I get home. This could be left over from a limitation I had in my code where our internal locator required a city or zip. I'll see if I can fix that.

Thanks for pointing it out.

I appreciate it Rene.

Since we are geocoding within our city only, there is no need for us to use City, State or Zip.
The widget will help greatly.

Thanks !!

Nestor.

Good Morning Rene,

I have installed the uncompiled version using my own geocoder. Compiles fine with no errors.
When I geocode a dbf files of addresses that are known to be correct, I get no results or errors.

The fields in the dbf file show up and I select the Address field but nothing happens. I am only using the Address field and not City, State or Zip.

I can take the same addresses in the file and locate them using the Find Address widget which is using the same geocoder.

Any suggestions?

Thanks !!

Nestor.

ReneRubalcava

This widget has been updated to that you can now edit your results and attempt to rematch the addresses to get a better score.
