Urban applications
Some local governments and agencies are working with remote sensing data but there is not much information out there.
Urban remote sensing is difficult because involves a huge variety of materials but still, some things can be done and classifications made.
I think it would be really interesting and useful to add this "Urban applications" category.

Plant specific VI's
If you know any indices for the identification of specific plant species you would like us to add, please send them to us with literature references and we will include them into the IDB.

Deimos-2 sensor
Could you include Deimos-2 in your sensor database?.
You can find more information in the Deimos Imaging website.

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'.
