I actually need the output in Decimal Degrees, the
problem seems to be converting from EN to LL within the batch script. I
keep getting EN coordinates output despite the changes I've made to the
get algorithm topleft (from eastings|northings to
latitude|longitude) and set algorithm coordsys to ll. I'm
guess this is because the batch script is reading the coordinates from the ERS
file and not from the geoposition function within ERM.
I may have found a way to convert the EN
coordinates in a text file to LL using Maps3D, but I'll have to wait a few days
to test that out. It's too bad I couldn't find a way to do it in ERM, I
thought I was getting really close with the togeo utility, but
at 3am last night I had to give up and look for either another solution or some
help. Too bad Eric hasn't offered one of his batch script writing course
in Vancouver, BC in the last few years. Thanks again for the utility
Lance, it works really slick.

or
you can just add code to convert the output decimal degrees to degrees minutes
and seconds. the rundown....(taken from about.com)
1. The whole units of degrees will remain the
same (i.e. in 121.135� longitude, start with 121�).
2. Multiply the decimal by 60 (i.e. .135 * 60
= 8.1).
3. The whole number becomes the minutes
(8').
4. Take the remaining decimal and multiply by
60. (i.e. .1 * 60 = 6).
5. The resulting number becomes the seconds
(6"). Seconds can remain as a decimal.
Take your
three sets of numbers and put them together, using the symbols for degrees
(�), minutes ('), and seconds (") (i.e. 121�8'6"
longitude)
yeah! more text parsing and converting to numbers! that
will probably eat a lot of CPU cycles and memory, though.
Hi All,
Does anyone have an example of how to integrate
the togeo utility program shipped with ERM into a batch
script? Thanks to Lance I have a batch script that will
provided me the bounding coordinates of ERS datasets in East/North.
Unfortunately, converting the output coordinates to Lat/Long seems to
be more complicated than changing the get algorithm topleft
from eastings|northings to latitude|longitude. I also tried
adding the set algorithm coordsys to ll, with no
luck. The coordinate values are still returned as the local projected
coordinates, and not as geographical. My only option seems to be to
use the togeo utility to convert the coordinates in the
batch script before they are output the text file. Any help would be
greatly appreciated.
Best Regards,
