Worldview 2-band combination

Last week I wrote up a cheat sheet for transitioning from Landsat 7 to Landsat 8 that went into the band specifications and listed some common band compositions. due to popular demand, I'm going to do something similar for worldview 2. if you're not familiar
With this sensor, it's unique in that it has a coastal blue band, a yellow band, a red-edge band and two near infrareds. i'll be honest; I was unfamiliar with worldview 2, so I had to do a little research into it. there are not a whole lot of papers out there,
But using this white
Paper from digital globe as a guide, I was able to develop and test some composites that utilize these bands that you don't see very often on other sensors.

Feature R G B
Vegetation Nir2 Yellow Coastal
Shadow Nir2 Red Edge Yellow
Cement Nir2 Yellow Blue
Sedimenation Red Yellow Coastal
Mud flats Red Edge Yellow Coastal
Red roofs Red Yellow Green
Water Depth Yellow Green Coastal

This is by no means an exhaustive list of what you can use these bands. please post suggestions/criticisms in the comments. from what I gather, there's a lack of information out there regarding this sensor and its applications. here are screen shots from
The composites I came up.

Vegetation composite (left ). nir2 | yellow | coastal. higher levels of vegetation correlate with deeper reds. I thought this did a pretty good job from low to high levels of vegetation. A traditional false color composite (NIR1 | red | green) is shown on
Right. Dubrovnik, Croatia.

Shadow composite. nir2 | red edge | yellow. there are a few options here, inconfigurating both a NIR band and the red-edge band, plus any other visible band. this combination seemed to make the shadows pop out more. dubrovnik, Croatia.

Cement composite. nir2 | yellow | blue. there are a few options here. I chose this one because there's a greater distinction with what's on the cement (I. e. painted stripes and cars) than what I saw in the other potential composites. dubrovnik, Croatia.

Red Roof composite. Red | yellow | green. Dubrovnik, Croatia.

Water Depth composite. Green | Blue | coastal. Dubrovnik, Croatia.

Mud Flat composite. red Edge | yellow | coastal. you heard it here first. this is the Al Khor wildlife reserve in Dubai. the green areas are mudflats used by flamingos for breeding and feeding. you can see the channels that cut through the flats well.
