4-channel ECW in Apollo Essential

Hi!

 

I got a 4 channel ECW from a customer.

Editing the "default" Style I can change from normal RGB to infrared (as described http://community.hexagongeospatial.com/t5/ERDAS-IMAGINE-Q-A/Displaying-4-band-images-as-RGB-in-ORIMA...

 

But if I use the ecwp within GMSC I always get the same result, no matter how I change the "default" style.

Looks like the style is only used within the Apollo Essentials console, or where is my mistake?

 

regards

Wolfgang

Hi Wolfgang,

 

The styling is not applied for ECWP. With ECWP, the APOLLO server just extracts the compressed packets from the ECW/JP2 file and send them to the client. The client is responsible for decompressing, reprojecting and styling the data. There is no processing on the server side.

So, if the client has no styling capability, you need to prepare first your ECW (choosing the bands, applying the stretch, etc.).
