Terralink International has selected the ER Mapper image processing application to assist in the datum / projection conversion of existing image catalogues. Terralink will be converting its assets from NZMG49 to NZTM GD2000 and vice versa using the NTV2 grid transformation.
Many of the datasets used by Terralink are more than 30GB in size. Many of these datasets will be split into 1:50k topographic sheets, to facilitate management and tracking.
