Am having a lot of difficulty doing simple things.
I gave up on trying to translate it using gdalwarp. I just get negative
numbers similar to original info below, not UTM numbers
So I tried stripping the data out of the tif by using Photoshop, saving
as jpg, then geo-referencing it into QGIS. I set up the base projection
as EPSG:32610 (WGS84 UTM zone10n) and then put in 4 points according to
the UTM grid markings, but it renders as a thin vertical line!
I used these UTM numbers according to what was on the tif,
upper left: 480000, 4607000
lower left: 480000, 4595000
lower right: 489000, 4595000
upper right: 489000, 4607000
And WHY do I have to set the CRS in two spots in QGIS????(under
settings/project properties, and settings/options).
Very frustrated.
Using Gdalwarp.
I have a California geotiff, that says it is Albers conic equal area,
nad83, which I figured was EPSG:3310, yet no matter what I try, cannot
get it into WGS84(EPSG:32610).
I looked at the file in its native format using FWTools GUI, and this is
what I get..
