IndianaView
Purpose:
Promote sharing and use of public domain remotely sensed image data (aerial and satellite platforms) for research, education and applications.
Part of AmericaView Inc.
Indiana Geographic Information Council
AmericaView Purpose
AmericaView is charged with helping the university, secondary-education, and public sectors in each state identify, develop, and distribute the kinds of remote sensing data & applications each state needs most.
There are now 27 state-views. Some are full members (funded) and some are associate or affiliate members.

IndianaView-GloVis
Software provided by USGS
More than 175 Landsat TM & 180 ASTER scenes of Indiana are available
Corona & MODIS scenes to be added

GloVis Menu Options
Ortho option is link to ISDP.
Political boundaries option is the default.
Search limits option is very helpful to limit the number of scenes being displayed.

Window to Download Image Files & Metadata
Example Window to Download Image Files & Metadata
This window is for Landsat 7 data which has 3 different resolutions (files).
Landsat 5 & others have just one file.

PTO Data Portals
SeaSpace TeraScan software allows us to generate products automatically and push to researcher site.
Team with Purdue’s TeraGrid project working on a subscription service to make ndvi, optical depth and radiance modis data for Indiana available for all via web services.
Will develop capability to allow specific data products to be downloaded from the IndianaView GloVis data portal
