Description

This davinci structure is created from files containing ISIS header information. The x and y coordinate on the planet are extracted along with the width and height of the data. This specific organization of data is used for mosaicking THEMIS data in davinci. There are various functions whch require this input format. Some examples of these functions can be seen in the Mosaic Tools category. To put an ISIS file in this format the function v_make must be used.
