How to Add Georeferencing Labels to an ISIS Cube
Bring in Raw Image
- PDS Image
- Run 'pds2isis' to convert the file to ISIS. You will likely need to run lev2lab to regenerate the mapping labels as outlined below.
- Make sure to record the PDS label information (lat and long range, resolution in km/pixel etc…) by viewing image label in a text editor.
- Other Formats
- Open the image in Photoshop, xv, or other program.
- Write down the number of lines and samples
- Save the image in a RAW format
- Get the image to machine that can run ISIS
- Run TAE, (tutor) t raw2isis
- From = RAW file (filename.raw)
- To = imagename (.cub extension is default, so do not add extension)
- Itype = 1 (8 bit)
- NS = image width
- NL = image height
- Run TAE, t lev2lab
- From = imagename.cub
- targdef = "Planet" - whatever planet you are working on i.e. "mars"
- Mappars
= "PROJ:clat,clon,latsys" whatever
projection you are working in.i.e.:
- "simp:0,ographic"
- "pola:90,0.ocentric"
- "merc:0,0,ographic"
- Lat = latitude range
- Lon=longitude range
- Resolution (use
only one)
- KM = resolution in km/pixel or
- DEG = resolution in pixels/degree
- Latsys = "ocentric" or "ographic"
- Lonsys = "180" or "360"
- Point
= "lat, lon, line, sample"
- i.e. top left pixel for a global image in Simple Cylindrical would be "-180, 90, 0.5, 0.5"
ISIS has now generated enough mapping information for GIS programs. If you desired to bring the im mage into ArcView or other GIS follow the tutorial here.
