enter address but zoom to polling place

Anonymous User

Original User: alnesbit

Hello everyone,

I currently have my flex map from the viewer 2.1 set up to get to a polling place in a 2 step process. First the user enters their address in my locate widget. It zooms to their address. On the map is the name of their precinct (labels on the precinct polygon). Then in the search box they enter their precinct number and then they click on the polling location that shows up in the search results and it zooms to the polling place point.

Is there any possible way to make this one step? Where the user enters their address and it automatically goes to the polling location?

I'm having trouble thinking of how this would work. Appreciate any help,

Andrea,

locate widget returns an XY for the address use a mappoint created from that XY and query the polling locations layer using esriSpatialRelIntersects and the mappoint as the geometry of the query. When the polygon comes back for the polling location use that polygon as the next queries geometry searching for the polling location point layer that esriSpatialRelContains.

Ok, let me see if I follow you. This wouldn't depend on the polling place points falling within the correct precinct polygon, would it? Because I have polling places outside of their correct precinct, if that makes sense. I also have multiple precincts going to one polling place. But I guess it's sort of a couple of spatial joins?

Thanks,

Andrea,

Well do the precinct have an attribute that has the proper polling location name then? If so then just use that to do a non spatial search for the polling location name on the polling locations layer.

Robert and everyone else,

Ok, I have started to look more at the code side of the flex viewer. I also listened to all of the training videos I could find, including 2 from the 2010 Developer Summit meeting in March. I need to make my own widget so I figured I would need to start with the LocateWidget and change it.

I have learned a lot but I'm afraid I'm still a long way from figuring out how to code this.
I have learned that the FindTask is a non spatial search, the QueryTask is done on one feature in a service and is a spatial query using geometry, I will need to use binding {}, returnGeometry="false" is used to not show the results of a query, chaining is what I will need to do to use the results of one for the next query. I was looking at the "RouteDirections.mxml" sample because it takes 2 addresses, sends them to the geocoder, gets the points back and then sends the route. I need to do part of that so I thought I could learn something and use that code but this is still a bit over my head.

The LocateWidget confuses me. I was comparing it to the LocatorTask.mxml sample and in that sample you can give the textboxes default values, like text="redlands" but I can't find where I could do that in the LocateWidget because it seems to be set up differently.

I'm pretty clear on the steps, I'm just not clear on how to code it! ha. I need to get the xy location from the address that the user selects in the LocateWidget. I need to turn that xy location into a mappoint. Using that mappoint I need to do a QueryTask with the precincts poly layer using esriSpatialRelIntersects. I will then get the name of the polling location from a field within the precinct poly feature class. Then I need to do a FindTask to query and select the same polling place name in the polling place point feature class and then I can zoom to the selected point.

I know there is another sample out there for the last query, but I'm stuck at the beginning. Does anyone have any hints or other places I could go to figure this out?

Will be cool when it works. Thanks in advance,

RobertScheitlin__GISP

Andrea,

Take a look at this example. It is basically what you are wanting. What it does is uses my locator to get the XY of an address and places a graphic on the map, then queries the districts layer and gets the polygon district that intersects it and then uses that polygon to find the schools points that are inside it and attaches attributes from the schools results to the original graphic of the address.

Hope it Helps.

Robert and everyone,

I have tried to take your code and change it to do my tasks. I'm happy to say that I finally understand all of your code. But I have not been too successful changing it for my project.

I can't even get it to geocode my address right now. Do you see anything wrong with my code? Do you see anything else wrong, right away?
The locator works in ArcMap. It's a 9.3.1 composite locator because I can't get Arc10 to create a composite locator - keeps giving me error message.

Appreciate any help. Thank you!

Robert,

Thank you so much! I'm getting closer every step.

Now all I have to do is change it to zoom to the polling point, not the address point. I'm afraid I have made a real mess of this code. I am attaching below. I sort of understand the concept. I need to use the query2 geometry and use that to zoom to. But I'm trying to use the sample "QueryTaskOnMap.mxml" and mix it with the code I already have. In most spots I'm guessing as to how it might work. And of course now I'm getting the warning: Data binding will not be able to detect assignments to "queryTask2".

Do you have any further guidance or ideas of where I could look to get this to work? I'm sorry to keep asking. I sort of dove into the deep end of the flex pool instead of wading in from the shallow side!

Andrea,

OK, here is the app reworked. It had my head hurting until I looked at your data closely.

Robert,

Sorry for the delay - I've been working with this since you gave it to me. THANK YOU SO MUCH!! It works great!

I have inspected the heck out of this code and it's very, very close. I copied and pasted the infowindow so that it shows on the polling place right away before clicking on the address point or the row in the grid.

I also played around with the extent and the center map. I think they want it to go right to the polling place without showing the address point, necessarily. So I changed it to do that.

The things I'm trying to learn in a hurry now are how create a more advanced looking page - layout, text. I think it's works just fine but I know the first thing they will say is "this doesn't Look very good". So I've been reading like crazy in these flex books and online.

I'm also having a huge problem because the first thing I showed them was the flex viewer with widgets. So now I'm baffled as to how to take this fully functional application and turn it into a widget for the flex viewer instead. I was about to formulate another forum question to this effect. The flex viewer is just really confusing code for the beginner and there's no real guidance on how to create your own widget on the resource center.

Thank you!

Just wanted to say I have the app working and I have it also looking great! I was able to figure out how to do some design work.

Thank you!

Andrea,

That's good news. Is your application publicly accessible?

Anonymous User

Original User: alnesbit

Robert,

Yes, it is. I will say, though, that it's on the client's server and it is really sssslooooow. It takes forever for the map part to load. And actually this morning, the map doesn't load at all. hmmm. I know part of the reason it's so slow is the aerials, which are not cached but don't turn on until you zoom in. But also I think their server is just slower in general. Oh and also I renamed the html file to "index.html" and it says it should load as the default, but it won't and you still have to put /index.html, not sure why.

check it out http://66.119.8.142/christiancoclerk/index.html

RobertScheitlin__GISP

Andrea,

The index issue is most likely if you are using IIS that index.htm is part of the default document types but index.html is not. Looks good the only thing that is a draw back for me is the size of the map. But that is because I am use to the map being the focal point.

Robert,

Thanks. Yeah, exactly. Believe it or not I tried to make the map as big as I could. But I still had to fit in all the instructions about how to use the site, the address input button, the links at the top and the banner. You should have seen it with the original banner size, it was quite funny how small the map was.

Hi Robert,

Well, the client didn't like it. She wanted it just like another website that she had seen. So I changed the layout and colors and etc. Check it out http://66.119.8.142/christiancoclerk/

I also fixed the "index.html" thing, thanks.

I have a few new questions for you if you're not too annoyed and have time.

1) Do you know if I can make the grid go down vertically? For instance, have the Address, then below it the cell for the Geocode Score, then below that the cell for the Polling Place? I looked around but didn't see a property like that.

2) What code do I need to add so the user can hit Enter on their keyboard and not have to click on the "Locate" button?

3) Do you have any idea how I could put a scroll bar on the side of this whole application, like a normal webpage? I've tried it several different ways and it always messes up the layout somehow and doesn't add a scroll bar.

Thanks a million!

Andrea,

1. I have not seen any ability to do that with a datagrid but you could use a datagroup and an custom itemrenderer.
2. Add these lines to the init function: (document.getElementById('Andrea').focus(); 'Andrea' has to be replaced with your applications name i.e. the name of the main.mxml.

    navigateToURL(new URLRequest("javascript: document.getElementById('Andrea').focus();"), "_self");
    //Now give the focus to the first input
    inCity.setFocus();

and change this line:

<s:TextInput id="inCity" text="Billings" enter="locate()" />

 <s:Scroller height="100%" width="100%">
  <s:Group>
   <mx:VDividedBox height="800" width="100%">
    <s:VGroup height="100%" width="100%">
     <mx:Image source="assets/images/newheader.jpg"/>
     <s:Label text="    Step 1:  Enter the address that you are intrested in below. Then Click Locate."/>
     <s:HGroup verticalAlign="middle">
      <s:Label text="    Address:"/>
      <s:TextInput id="inAddress" text="306 Washington" />
      <s:Label text="City:"/>
      <s:TextInput id="inCity" text="Billings" />
      <s:Button id="locateBtn" label="Locate..." click="locate()"/>
     </s:HGroup>
     <s:Label text="    Step 2: Click on a row in the grid to get details on the location. The Geocode Score is a percent of how closely your address matches the address listed." />
     <esri:Map id="map" zoomSliderVisible="false" height="100%">
      <esri:ArcGISDynamicMapServiceLayer

     </esri:Map>

    <mx:DataGrid id="resultsGrid" itemClick="onItemClick(event)" width="100%" height="87">

Robert,

Thank you so much! My trial version of Flash Builder ran out, lol! So I have to wait until next week when it arrives in the mail and I get it installed before I can try out your code. I will keep you posted...as always! 🙂

Happy Valentines Day! Just think, if everyone who you helped sent you flowers or candy today, your desk would be overflowing!!!

Thanks again,
