I upgraded to Version 2 of the Google Maps API. The benefits of Version 2 of the API that are applicable for the ENVI lookup user routine are:

  1. The Overview map control displays a collapsible overview map in the lower-right corner of the browser window.
  2. The Javascript is half the size, so it should be a faster download.
  3. Increased imagery resolution and coverage.
  4. Other customization features make future enhancements to MG_GOOGLE_LOOKUP possible.

Google Maps Version 2 lookup for ENVI

The best part is that all the changes are on the server side, so this will just happen automatically for those who are using MG_GOOGLE_LOOKUP already. If you for some reason want to keep using Version 1 of the Google Maps API, change the URL inside MG_GOOGLE_LOOKUP from envi_lookup.html to envi_lookup1.html.
