[Geotools-gt2-users] Questions about deriving GridCoverage2D from a Raw (Unencoded) multiband image

[Michael O. <m.o...@ja...>]

Dear All,

 

I am wondering how do I derive/define a gridcoverage2d from an array of
image cell values, arranged in a way such as this -{ pixel 1 band1, pixel 1
band 2, pixel 1 band 3 ...pixel 1 band m, pixel 2 band 1,  pixel 2 band 2,
pixel 2 band 3 .pixel 2 band m ...pixel n band m} (-this is actually a
matrix of numbers (pixel values) sitting in a database); and I have its
associated metadata - such as bounding box, coordinate system,  etc on
another file.

 

Do I have to extract all the values for a band, and associate a sample
dimension and envelope to each band  and then create a grid coverage2d for
each band separately, or how do I pass the number of bands in unencoded
image to the gridcoveragefactory to create a multiband image for me!!!!

 

 

Thanks,

 

Michael
