What’s new to misr_view 4.0?

• Data transform utility– allows mathematical formulas to be applied to data– transforms are stored in editable ASCII files– accommodates access and application of HDF-EOS grid

attribute metadata values

• Map projection tool– reproject data into any IDL-supported projection– reproject data from linked windows into same projection– multiple georeferenced data can be reprojected into the same

projection

New Features Cont.

• Vector overlay tool– Display any vector-based data over images Ex. wind speed/direction

• Color bar utility– Select any IDL color palette – Pseudo-coloring single bands of data– Modify annotation – Resize

Other Functions

• Store/Recall all options in the data selection interface– especially useful if the same parameters need to be accessed

frequently

• Rotate data– required for viewing stereo anaglyphs
