ESRI’s ArcGIS Online team has published a service containing recent imagery obtained from NOAA and showing the aftermath of Hurricane Ike for the Galveston, Texas, area. These are now available to ArcGIS Explorer users as a complete map or a layer that can be added to an existing map. To open these in ArcGIS Explorer, just click the map or layer below and choose download:
(Note: To use the files above you will need to download and install ArcGIS Explorer. First-time users should choose the map file, which will automatically zoom to the Galveston area. The layer file will add the imagery as a new layer in your existing map.)
Here are some sample screenshots showing the service contents. The first is an overview showing the NOAA imagery mosaic on the Explorer default map. The imagery can be seen as the lighter colored green bands.
Here’s a view of Galveston Channel, showing the NOAA imagery with the USGS topo layer from the ArcGIS Explorer Resource Center.
Here’s a view of hurricane damage using the Swipe tool, allowing us to view the pre-Ike imagery (on the left) with the post-Ike imagery (on the right).
The imagery is part of the ArcGIS Online World User Imagery collection.
