size)
i. ./miniconverter
1. this creates the .hdr file and the .hrw file
6. Copy tiles
a. First check directory – pwd
i. cd /data/scratch/kal/TileOverviews
ii. cp –r /data/scratch/smather/TileOverviews/ss07-09/
1. note: no * after ss07-09/
.
Load corresponding “TILE(s)” into viewer which are saved on a DVD.
b. First make a new directory in “FROSTY” – mkdir “tile name”
c. Run geolocation script
i. cp tileconverter ss07-09/
ii. ./tileconverter
.
7. Import – into Imagine
i. From Imagines’ main tool bar –
1. TYPE – “ENVI (Direct READ)”
2. MEDIA TYPE – “File”
3. FILE TYPE – ENVI (*.hdr)
4. INPUT FILE – “MiniMosaic” – “mm_02_10.hdr” or for
“Tileoverview” IMG_0.hdr
a. Rename output to file name like “ss_10-12”
b. Click OK
i. Click OK
8. Load into viewer and set projection
a. Set Projection
i. Open Image into Imagine
Note: use “Data Scaling” to adjust brightness – find under “RASTER”
ii. Hit the image info button
1. EDIT
a. CHANGE MAP MODLE –
i. Change the units to meters
ii. Change projection to “Polar stereographic”
b. ADD CHANGE PROJECTION….. – from
projection choose “WGS 84 – for both Spheroid and
Datum
i. Latitude of true scale – “-71” then hit return
to set it, then click OK, finally click YES
