Hi Palani,

I think the polar region rectangle shape is not different with the other area rectangle shape, you should want to build that follow the parameters of our constructor.

I guess you means that’s under a different projection, you don’t need to try directly build a rectangle shape in target projection, you just need to build a standard rectangle shape then reprojection it to target projection.

Wish that’s helpful.

Regards,

Don

Hi Palani,

In fact, you should want to know the exact bounding box(rectangle shape) of your image when you get the image, that should be provide by your data provider.

But you cannot calculate that from your image, exception your image is special format and contains embedded bounding box information.

Regards,

Don
