ERDDAP   Easier access to oceanographic data

Google Gadgets with Oceanographic Data for Your iGoogle Home Page

Click on one of the buttons below to add a Google Gadget to your iGoogle home page.

Background Information

• Google Gadgets are self-contained chunks of web content that can be added to your iGoogle home page.
• Below are several sample Google Gadgets that always show the latest data from various oceanographic datasets in ERDDAP.
• For example, if you put a Google Gadget showing the latest Sea Surface Temperature on your iGoogle home page,
  it will always show you the latest Sea Surface Temperature data.

Alternatives

• Make Your Own Google Gadget, if you want a Google Gadget for a different dataset or geographic range.
• Embed a Graph in a Web Page - If you are a web page author, use this technique instead of Google Gadgets.
  It is simpler and more flexible than Google Gadgets (for example, you aren't restricted to .smallPng images).
• Use Slide Sorter. Anyone (even non-web page authors) can create their own iGoogle-like web page
  which can display images and other content, each in its own, draggable slide.
  It, too, is simpler and more flexible than Google Gadgets (for example, you aren't restricted to .smallPng images).

Make Your Own Google Gadget

1. If you don't already have a Google account, open one.
2. Use an ERDDAP Make A Graph web page to select some data.
   1. In ERDDAP, search for a dataset of interest.
   2. Click on the dataset's graph link to see the Make A Graph web page.
   3. Modify the graph until it looks like you want it to.
   4. Get the URL from the "view the URL" textfield.
   5. Replace all instances of "&" in the URL with "&".
   6. For gridded datasets, modify the URL to refer to the "(last)" date/time instead of a specific date/time.
3. Paste the following code into the Google Gadget Editor:

   <?xml version="1.0" encoding="UTF-8" ?>
   <Module>
   <ModulePrefs title="ERDDAP: SST, Blended, West US (Experimental, 5 Day Composite)"

4. In the Gadget Editor, modify the data descriptions as desired and insert the URL you generated in Make A Graph.
   Note that all the URLs for a given Gadget are the same except for the fileType (for example, .graph, .png, .largePng, .smallPng) in the middle of the URL.
5. Use the Gadget Editor's: "File : Save As"
6. Use the Gadget Editor's: "File : Publish"
