Detailed Description

class ossimTopographicCorrectionFilter

This clas is used to execute terrain correction. I t requires 2 inputs where the first input is a multi band data source to correct and the second is elevation normals used in light incident calculations.

A sample chain might look like:

landsatHandler —> Cache —> renderer —> cache ------------------------------------— |–> Topo correction filter —> Output ortho mosaic of elevation data-—> imageToPlaneNormals –> Cache —> Renderer –>Cache –

the ossimImageToPlaneNormalsFilter is used to take a single band elevation source and compute normals at each post. I suggest that you set the renderer to use a higher order convolution than just nearest neighbor, maybe Cubic. This way you have smoother interpolation as you change zoom levels.

Correction Types:

Cosine correction: In order for this to run it does not need any additional informat but the multi band source and an normal calculation input.

Cosine-C correction: In order for this to run it will need theC array populated for each band. It defaults to 0 forcing a default Cosine correction to take place.

Minnaert correction: In order for this to run it will need theK array populated for each band. The defaults should work pretty good

◆ getBoundingRect()

ossimIrect ossimTopographicCorrectionFilter::getBoundingRect ( ossim_uint32 resLevel = 0 ) const

This will return the bounding rect of the source.

We can have several sources which are in a chain to modify the bounding image rect. lets say you are next to an image handler then it will return the bounding rect for that image. If you are at the right side of a resampler then you will get a bounding rect along the image view plane. This is going to be a very import method for both image writers, mosaics or anything that needs to operate only within the bounds of an image.
