Confusion over image registration information
How to specify which area of the globe a satellite picture pertains to
that is, image projection, lat/lon of the bounding rectangle, projection parameters
This is necessary to correctly overlay the image on the map, and temperature, etc. isoplots on the image
- NODDS: catalogged fixed areas
- Satellite pictures are made for a few preselected areas
- Image file name = image catalogged name
- A client and a server must have identical catalogs
- Originally only 15 images were catallogged. A hassle of adding a new image
- We designed a new, flexible catalog format. Easy to propagate to clients
- TESS: MTIF
MTIF
: TIFF
with a registration information in private tags
- Originally some dumbheads "extended"
TIFF
by using native FP numbers in private tags: 2-3 month-long confusion of people and TIFF
readers (still goes)
- We proposed: put registration information in
DocumentName
tag in ASCII. My TIFF
writers do that, GOES writers do that
Just to show what kind of confusions one has to trudge through all the time...
