For GIS users involved in the Myanmar disaster and recovery, ESRI maintains a web site that lists a variety of GIS data resources. At that site those seeking software, data, or services and consulting help can find an online request form that will enable responders to obtain the needed resources. The site also includes a link to send email directly to the ESRI Disaster Help Coordination Team.

We'll also be spinning up some additional services via ArcGIS Online which we'll include on the Explorer Resource Center, and we'll publish info about those as soon as they are ready. Those ArcGIS Online resource will also be available to use in ArcGIS Desktop.

Many of the currently listed sources publish Myanmar map information as PDF documents. Here we've added a note and created a link to one of those online maps.

We took a look at the Google Lat Long Blog and found a post with a link to a UNOSAT KML with information about the cyclone. Here's the KML with the National Geographic political map from Explorer's Resource Center.

Here's the same KML and you can see that as the cyclone approached land it was a category 4, then dropping to category 2, and eventually dropping down to a tropical storm as it moved across the southern tip of Myanmar.
