The band math calculations were completed with OTB Orfeo open source remote sensing package.. it is nice because it preserves the geotiff information / metadata. This is a quick follow up to the last blog post with NDVI generation using two camera system.

I am busy working on a winning formula for my UAV setup. Once it is done I am going in the same direction using dronemapper. What they have done is so impressive.

Hopefully this is not a silly question but can NDVI be done at night?   We have much brighter lights that are very small and light,.. like XM-L Cree bulbs that output 1000+ lumens per bulb..  is it at all possible to do a NDVI flight using a UAV with the camera and lights.. or do you really need sunlight to do it..   NDVI uses visible + IR relectivity so in theory it does not need to be the sun.

NDVI can be calculated from the reflectance of artificial light. That is how greenseeker works...

@JP ... thanks for sharing your efforts. After reading your stuff,

1) did you compare (science) the quality of this one cam setup with your two cam setup, i am curious if vibrations are an issue?

2) did you also own or a test the 230HS cam

Thanx .cj

Can you please point me in the wright direction? I am very interested in aerial mapping and eventually 3d terrain mapping I would like to read about some information on how to begin. Is there a beginner guide or tutorial on the basic set up from beginning to end? I have gathered some information from other people’s questions from the internet but the info is all mixed up. Can I get the info all in one place? Please advise

@Alex, If you are interested in going to a workshop that covers this material, check out this event.   If you can't make the March one, there will be another one in August.

Is Dronemapper doing the NDVI for you or are you simply converting the final orthorectified image that they send you?
