Values range for the indices?

Also what dows the word 'automatic' mean in the 'calculated' column.
If you click on one of the references you will get a list of which indices are described in the article and which sensors are used and also possible applications described. For example Ahamed et. al. 2011: www.indexdatabase.de/db/r-single.php?id=355
You find also below each index and each sensor a list of the references we used for that, see REIP1 and ASTER as an example.
If you would like us to add an article, an index, a sensor or an application, please let us know. Because this a main idea behind this project, to make research available to a wider community.
To your second question: For the sensor specific formulas, the wavelengths are substituted by the sensor's band names. In most cases, this is done automatically by matching the formula's wavelengths and the sensor's bands. But sometimes we found in the literature explicit suggestions which bands to use. Then we used the suggested formula and set the 'Calculated' property from 'Automatic' to 'Manual'.

A very wonderful work.
Just one request: when will be available the information about Landsat 8 and some index about it?

a very great job. I am amazed about this extensive work. The necessary and really appreciated step would be to integrate a possibility for formula export. Are there any outlooks you can give?

adding sensor spatial resolution information
a suggestion could be adding the spatial resolution information of the sensor just next of the wavelenght visualization.
Thanks for your great job anyway!
If you find any missing data, just let me know and we will add them.
