team,

I need your advice on a new RGB function chain in MD, which will follow the following rules:

 

1. Input:  images already added in MD (6 bands per image, 16 bit pixel depth per image & MD);

2. Create RGB as 16 bit, where R is from band 3, B is from band 1, but G is calculated with the formula: band 2 * 0.7 +  band 4 * 0.1 + band 6 * 0.2 (used to identify types of insects diseases in farming and forest lands);

3. Output:RGB as 8 bit (ready for other tasks such as color balancing to match a 8-bit target, if necessary)

 

Thanks in advance

If you only have 4-band imagery like GEOEYE, G can be replaced with the formula like band 2 * 0.7 + band 4 * 0.3
