Saw a comment on Twitter from a random notes user (nishantmodak). The question was “Can I embed a Google map location in an email from Lotus Notes?”. The answer is Yes! 
Some important points first.
1. There is some security implications in doing this, so if your admins have locked down your ECL then you might not be able to do this. However if your a designer and want to do this in your application then these steps should work fine.
2. Your embedding a web browser control. So sending the mail to non-notes users may not work.
3. When I first tested this I was getting a javascript error. This was related to the google API. Although I am working on Dev builds of 8.5.1 and since last Monday that error went away (not sure if it is Google API issue or Notes).
4. I did have a couple of issues regarding editing the applet and I’ve logged them as SPR SODY7W6JXJ. So if you experience issues editing the applet and need to open a support call you can cite that SPR.
So on with doing this…
1. First we need to pick a location that you want to display. For my example we will be using my location.
On the google maps page there is a “Link” option. Copy the text from the “Paste HTML to embed in websites”.
2. Paste that text into anything that will allow you to edit it (eg. Notepad, notes document). The only part we are interested in is the You can ignore the rest. So we get the following snippet.
<iframe width="425" height="350" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://maps.google.co.uk/?ie=UTF8&ll=53.421669,-6.419148&spn=0.004661,0.008519&t=h&z=17&output=embed">
3. Do a search and replace on the snippet. Look for “&” and replace with “&” (remove quotes). You should end up with:
<iframe width="425" height="350" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://maps.google.co.uk/?ie=UTF8&ll=53.421669,-6.419148&spn=0.004661,0.008519&t=h&z=17&output=embed">
The URL we want is the value of SRC. In this case. Copy and keep that safe.
http://maps.google.co.uk/?ie=UTF8&ll=53.421669,-6.419148&spn=0.004661,0.008519&t=h&z=17&output=embed
You can also make a note of the width (425) and height (350). Although not that important.
4. First create your memo/document and make sure you have selected the rich text field. For the memo this is the main body of the mail.
5. Select the Create->Object… menu option.
6. A dialog box will appear. Select “Control” option then scroll down through the list and select “Microsoft Web Browser” and click OK.
7. An applet menu should be visible now. Press CTRL-K (opens the infobox). Select the applet infobox options by clicking on the top drop down list in the title. On the applet “i” tab select the option “Run object when reading document”.
8. Select the applet menu and “edit events and properties”. Here you can set the height and width if you want.
9. On the left side will be a list of methods. Select the Initialize method and then paste in the following code between the “sub” and “end sub” lines.
Dim w As New notesuiworkspace
Dim uidoc As notesuidocument
Dim doc As notesdocument
Dim browserobject As Variant
Set uidoc=w.currentdocument
Set browserobject=uidoc.GetObject("Microsoft Web Browser")
Dim URL As String
URL = "http://maps.google.co.uk/?ie=UTF8&ll=53.421669,-6.419148&spn=0.004661,0.008519&t=h&z=17&output=embed"
browserobject.Navigate(URL)
10. As you can see the URL is set to the URL we got earlier. Once you click back on the document (off the applet) it should automatically display the google maps location for you. An ECL message may appear asking permission to display it. Normally at this point I hit CTRL-S, in case I accidentally delete it and have to start again.
The end! 
Note: While this code went into the initialize section of the applet, there is no reason why it can’t go into a button you create.
