Hey , I dont'y have a file of latitudes/logitudes but i have plenty of addresses I'd like to map. Is there an api or web service I can use to geocode addresses. Can virtual earth take addresses rather than lat/lons?

re: Plotting Your Data Using Virtual Earth

Jon Campbell — Fri, 08 Jun 2007 06:49:39 GMT

When it comes to geocoding, things can get a bit complex. Depending on which mapping service you use to drive your view, you may or may not have a direct method to geocode your data. When using virtual earth, there is no straightforward way to give it an address and have it spit back lat/lon combination. There is a "FindLocation" function available, but that will center the map on that location and then you can plot your point. A way around that is to use a hidden iframe or div and load a second map in the background that you use for geocoding, similar to this article: http://msdn2.microsoft.com/en-us/library/bb259691.aspx.

Outside of that, there are a variety of other geocoders available. If you have a small number of points that are fixed, then perhaps geocoding beforehand via http://www.batchgeocode.com/ or something similar might suit your needs. Beyond that, you would need to check out the various geocoders out there. MapPoint Web Service includes a geocoder, but many people prefer the yahoo maps implementation because of its simplicity (http://developer.yahoo.com/maps/rest/V1/geocode.html).

With whatever service you choose to geocode your points, the basic gist of the task is the same. Rather than grabbing a lat/lon directly out of your data, you instead grab the address and feed it to a javascript function that will determine the coordinates for you and then plot the point. Make sure to do these calls asynchronously, otherwise you will lock up the browsing experience for your users.

Hi Folks,

We are very interested in learning how to to this with a WSS list as the source. However, we have no idea how to do that. We have been able to get the demo to work from an xml file, just baffled about the list. Thanks.

re: Plotting Your Data Using Virtual Earth

Jon Campbell — Tue, 12 Jun 2007 06:40:12 GMT

janderson02 - can you detail some specifics of what you are running into? The steps should be the same for a sharepoint list as with a xml file. The DataFormWebPart acts the same whether its working against a sharepoint list, xml file, aggregate data source, or other source. If you would prefer to take it offline, you can email me directly at joncamp at microsoft dot com.

re: Plotting Your Data Using Virtual Earth

Jeffrey — Thu, 14 Jun 2007 20:01:20 GMT

I downloaded the samplemappingsource.zip file and uploaded the files to a library on my sharepoint box and ran the simplemap example which worked fine. When I run the Dynamic map I get an error. I got this same error previously when I typed in the example…

Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Windows SharePoint Services-compatible HTML editor such as Microsoft Office SharePoint Designer. If the problem persists, contact your Web server administrator.

However Jon helped me out by explaining that I needed to edit my aspx page to tell it where to find the xml file since I had it in a subsite and not in the "Shared Documents" library...

re: Plotting Your Data Using Virtual Earth

Jon Campbell — Thu, 14 Jun 2007 20:32:52 GMT

As Jeffrey noted, if you put the sample files into a place other than the root of the site then SimpleMap.aspx renders fine, but DynamicMap.aspx shows an error message. To fix this, you need to update the FilePath parameter of the SPXmlDataSource to add the DefaultValue attribute such that it contains the path to where the locations.xml file is stored. It is a site relative path, so in my case it was stored at http://testsite/mysubsite/Shared%20Documents/locations.xml. Therefore the DefaultValue for the FilePath would be “Shared%20Documents”. See the following code:

<SharePoint:SPXmlDataSource runat="server" id="locations_x002e_xml1">

<WebPartPages:DataFormParameter Name="FileName" ParameterKey="FileName" PropertyName="ParameterValues" DefaultValue="locations.xml"/>

<WebPartPages:DataFormParameter Name="FilePath" ParameterKey="FilePath" PropertyName="ParameterValues" DefaultValue="Shared%20Documents"/>

</DataFileParameters>

</SharePoint:SPXmlDataSource>

</DataSources>

If you want to use this sample with a source other than an xml file (SOAP web service, sql database, sharepoint list, etc) you will want to start from scratch rather than working from the samples. Converting the provided sample code to an arbitrary source can be done but it’s not for the faint of heart. The main reason for that is to ensure that SharePoint Designer can do the work to make sure that the basic DataFormWebPart has all the right stuff to start from in terms of data sources, basic XSLT, etc.

re: Plotting Your Data Using Virtual Earth

Jon Campbell — Thu, 14 Jun 2007 21:39:21 GMT

A quick note about the geocoding issue:

The reason why FindLocation is unsuitable for the purpose described in this post is that it causes the map to be centered on the point that is found as a result of the call. Because of that, if you are plotting multiple points it causes the map to jump around for every address. The solution described in the msdn article that I linked to above (http://msdn2.microsoft.com/en-us/library/bb259691.aspx) is to use a second hidden map to find each address.

If you only want to show a single address then the built in geocoding will work just fine. You can simply call FindLocation with your address data, then add a pushpin at the center of the map. This works great if you are trying to make a detail page for a contact in your address book.

Help me please! I have an Address Lists (about 400 addresses) and I want to display them in Virtual Earth. How to display many addesses by adding pushpin in VE ?

re: Plotting Your Data Using Virtual Earth

Jon Campbell — Tue, 02 Oct 2007 05:47:54 GMT

Dacle - the easiest solution is probably to use something like http://www.batchgeocode.com/ to give you the lats/longs for the addresses, then add them as extra columns on a sharepoint list. If your data is in sql or something and you don't have the ability to add the data to the source, you can create a parallel list and use an aggregate datasource to correlate the lat/long with the address.

re: Plotting Your Data Using Virtual Earth

Jon Campbell — Fri, 02 Nov 2007 05:33:11 GMT

With regard to the comments about driving directions - its super easy to do! You don't even need to have the virtual earth map or anything, you can just format your address and you are good to go. That url has info on building your own url.

http://help.live.com/Help.aspx?market=en-US&project=WL_Local&querytype=topic&query=WL_LOCAL_PROC_BuildURL.htm

For example, if you were going to go to Chicago but wanted to let the user put in their own starting point then you could use a url like this:

http://maps.live.com/default.aspx?v=2&rtp=~adr.Leavenworth,%20Washington">http://maps.live.com/default.aspx?v=2&rtp=~adr.Leavenworth,%20Washington

In the sharepoint contacts list case, you would probably want something like this:

<a href="http://maps.live.com/default.aspx?v=2&rtp=~adr.{@WorkAddress},{@WorkCity},{@WorkState},{@WorkZip}">Get directions!</a>

mswin — Fri, 02 Nov 2007 13:01:51 GMT

Hi,

Its a great post.

I am strucked with some problem using Javascript in xslt.

I have javascript on my xsl file.

In the javascript I have a method, which return some databsed on browser locale.

Based on the value returned by the javascript function I want to set the value for xslt variable or parameter.

I want to use this xslt parameter value and include some other xsl on condition basis.

How to set the xslt variable value from the javascript. My Javascript is there in the xslt itself.

My requirement is, I want to include culture specific xsl in my main xsl based on the value from Javascript.

Any help will be highly appreciated.

re: Plotting Your Data Using Virtual Earth

Jon Campbell — Sat, 03 Nov 2007 07:45:05 GMT

mswin: The situation you are describing is somewhat backwards to what we are doing in this post. The method described above uses xsl on the server to generate javascript that is inserted into the page markup, which in turn is run by the client. What you seem to be describing is the reverse, which is a rather different scenario.

While your scenario is somewhat vague to me, in general you can pass values to the DFWP using parameters. Those parameters are in turn available to the xsl as <xsl:param> values. So, if you have javascript that you want to pass a resource to a DFWP via the query string, you can create a query string parameter on the DFWP and then have your javascript open the appropriate page passing in the data that you got via your call.

If that doesn't make sense then you can contact me offline at joncamp at microsoft dot com and then we can discuss if this method will suit your needs.

Jon,

Is the use of this code to display a virtual earth map in a Sharepoint Intranet Portal depend on us having a MWS/VE agrrement/license?

re: Plotting Your Data Using Virtual Earth

Jon Campbell — Tue, 06 Nov 2007 05:37:20 GMT

judysemo: You should check the licensing terms for Virtual Earth since I am not a lawyer, but the above code is just like any other mashup or VE application that any site would use. I think http://www.microsoft.com/virtualearth/product/terms.html has the info that you are looking for. From the looks of it, as long as you arent hitting 100k transactions in a 24 hour period you should be fine, but check the terms to be sure.

re: Plotting Your Data Using Virtual Earth

Tom Resing — Wed, 05 Dec 2007 18:50:14 GMT

Jon,

I'm also interested in the answer to Judysemo's question. The third paragraph of the terms states "You are not permitted to use the API or the Service on any intranet or non-public website, unless You have a MWS/VE Agreement that includes such rights."

I've expirimented with the Virtual Earth API on an intranet and it does work. On the other hand, the Google Maps API actually prevents use on an intranet because of similar terms.

Your answer and the fact that it actually works on an intranet suggest there is some gray area in the terms. Do you know if that is true?

Tom

Perhaps checking on the Virtual earth forum (http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=537&SiteID=1) might shed more light.

dash — Tue, 11 Dec 2007 20:09:17 GMT

Is there any way to display a more minimal zoom menu ? I have this in a sort-of small part of my page [about 400x300px], and the zoom/menu kind of takes over.

I'm also looking to use some non-standard icon, I see that the AddPin() function is called with an 'iconurl' parameter, but it doesn't seem to be used in the actual function. Is it still, just not visibly ? Also, how should I align my icons so that the pointer-part of it is still in the same place ?

I cast my vote for built-in geocoding support too. I'm fine with using batchgeocode or something, but my nontechnical clients get confused easily. :)

Also, using non-integer zoom levels is rather amusing, nice error handling. :P

re: Plotting Your Data Using Virtual Earth

dash — Wed, 12 Dec 2007 23:02:34 GMT

I've solved my own problems, if anybody else wants them:

You can hide the zoom/navigation menu by applying the following stylesheet:

"#myMap_dashboard {visibility:hidden!important;}"

Custom icons can be used by implementing this:

Change the 'null' in the original call to AddPin() to a link to an image that you want to use instead of the default.

Add this line to the AddPin() function: "shape.setCustomIcon(iconurl)", before the map.AddShape() part, but after the shape object is created.

Have fun!

The code I used is:

function AddPin(lat, lon, iconurl, title, desc)

{

var shape = new VEShape(VEShapeType.Pushpin, new VELatLong(lat,lon));

shape.setCustomIcon("<div><img src='dot.gif'/></div>");

shape.SetTitle(title);

shape.SetDescription(desc);

}

and on a note dot.gif is sitting at the same place where my aspx page is.

I really appreciate what you've shown me here. I was able to disect your code and in turn change the data source from the XML into the one of the lists on my site. Unfortunately all I had was addresses in my list so I geocoded the info to get my LatLong info and now I have a list that is plotted against a VE map. Thanks again.

re: Plotting Your Data Using Virtual Earth

Jon Campbell — Fri, 21 Mar 2008 06:53:25 GMT

Nitu: To combine data from multiple lists, there are two ways that i have tried successfully.

1) instead of using an SPDatasource, use an aggregate datasource which contains the two lists you want data from. Then just manipulate the XSL to point to the right places.

2) use the "hidden iframe" technique to load the second page into a hidden iframe, then use javascript to pull data out of that page into the div for the popup.

re: Plotting Your Data Using Virtual Earth

Simon Gregory — Thu, 03 Apr 2008 14:16:18 GMT

Hi, thanks for this. I have modified the code to use a list of input and I have changed to version 6 of the API. All works great.

I want to now improve my solution:

Once I have plotted the points I want to center and scale the map to show all the plotted points.

I was hoping to do this by using the VEMap.SetMapView method. This method needs an array of the plot points. That is straight forward (I think) I just created an array and I push the VELatLong objects into it just after I have plotted them.

However, I am very new to xslt processing and my big problem is where/when to run VeMap.SetMapView method. I thought I had found the place that I thought it was logical to put it but that did not work.

Any help with this would be appreciated.

Thanks

Simon

re: Plotting Your Data Using Virtual Earth

Jon Campbell — Tue, 15 Apr 2008 19:46:54 GMT

Simon - based on what you are describing, you will want to modify the AddMapPins template. The code above is pretty simple in that it creates an AddPin() call for each row of data. A better way would be to have the AddMapPins template generate the array of points. Something similar to the following should be close to what you want.

<xsl:template name="AddMapPins">

<xsl:param name="Rows"/>

<xsl:text disable-output-escaping="yes"><![CDATA[

var mypins = {

]]></xsl:text>

<xsl:for-each select="$Rows">

<xsl:if test="not(normalize-space(@lat) = '' and normalize-space(@long) = '')">

new VEShape(VEShapeType.Pushpin, new VELatLong(<xsl:value-of select="@lat" />,<xsl:value-of select="@lon" />)),

</xsl:if>

</xsl:for-each>

<xsl:text disable-output-escaping="yes"><![CDATA[

}

</script>

]]></xsl:text>

</xsl:template>

Then you would want to modify the GetMap() function to call your SetMapView with those pins, and also modify the addpins function to add each of your pins to the map. http://dev.live.com/virtualearth/sdk/Ref/HTML/M_Namespace_VEMap_SetMapView.htm has a good example of the basic concept.

re: Plotting Your Data Using Virtual Earth

Jon Campbell — Fri, 18 Jul 2008 01:29:02 GMT

Aaron - you don't have to show the list on the page - I just did that for clarity's sake. If you don't want the table to be shown, just delete the <table> tag that is after the call to AddMapPins. For completeness you should delete the dvt_1.body and dvt_1.rowview templates, but you don't have to.

In terms of using a list instead of the xml file - the process is basically the same. the biggest difference is that inside the AddPin template you will need to change the fields that are referenced. for example, if you call your latitude field "Latitude", then you will want to change the "@lat" to be "@Latitude".

I have it working from the xml file with no issues, i've also been able to modify various aspects of it, but one thing I cannot get to work is getting it to read from a sharepoint list. I basically tried to replace the paths that would point to the xml file and make them point to the location of the list, but that only resulted in an error at the bottom of the map. I changed the datasources names to represent the fields but that didn't do anything either. I'm not a coding or sharepoint guru to being with, can someone point me to a sample code that shows how to reference a sharepoint list rather than an xml file? Thanks in advance.
