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
