#760: Location wizard: region, UTM, search for EPSG
-----------------------------+----------------------------------------------
Reporter: helena | Owner: grass-dev@lists.osgeo.org
Type: defect | Status: new
Priority: major | Milestone: 6.4.0
Component: default | Version: 6.4.0 RCs
Keywords: Location wizard | Platform: MacOSX
Cpu: OSX/Intel |
-----------------------------+----------------------------------------------
Here are few Location Wizard issues - there may be more:

Apparently Universe is still there for UTM, see here
http://lists.osgeo.org/pipermail/grass-dev/2009-March/042951.html

if startup has grassdata but I create location in tgrassdata using wizard
it tells me that I will need to change into tgrassdata
but then it asks whether I want region I say Yes and then I get Error in
command execution g.region because
wizards g.region still looks into grassdata and tells me that the location
does not exist -
it needs to look into tgrassdata for the new location or skip the region
creation in this case.

EPSG search works but if I type name North Carolina it picks up the first
one and moves on - would it be possible to select all that have North
Carolina in it and then the user selects one of them?
Searches for projection and for Elipsoid already do it, which is very nice
(you give it search for Lambert and you get all 3 that are there)

For the chose projection when you type UTM into projection code and click
Next nothing happens - this is because you should type utm so it is not
clear what to do next or what is wrong - maybe an error message that UTM
does not exist? to make the user scrolls down and looks for the correct
code?

If I select datum with associated elipsoid and then pick up nad83 it again
does not do Next and it is not clear what is wrong

At least the region issue and UTM search should be addressed before
release, I believe

if startup has grassdata but I create location in tgrassdata using wizard
it tells me that I will need to change into tgrassdata but then it asks
whether I want region I say Yes and then I get Error in command execution
g.region because wizards g.region still looks into grassdata and tells me
that the location does not exist - it needs to look into tgrassdata for
the new location or skip the region creation in this case.

--Although it can create a location in another GISDBase, g.region and
g.proj run in the default GISDbase--i.e., the one you started in. So you
can't get region info from a location in another GISDbase folder (at least
not easily).

EPSG search works but if I type name North Carolina it picks up the first
one and moves on - would it be possible to select all that have North
Carolina in it and then the user selects one of them? Searches for
projection and for Elipsoid already do it, which is very nice (you give it
search for Lambert and you get all 3 that are there)

--I'm not sure how doable this is given the way that the EPSG file is
structured. However, it's worth looking into.

For the chose projection when you type UTM into projection code and click
Next nothing happens - this is because you should type utm so it is not
clear what to do next or what is wrong - maybe an error message that UTM
does not exist? to make the user scrolls down and looks for the correct
code?

--you mean it is not recognizing capitals? UTM vs utm?? This should be
easy to fix.

If I select datum with associated elipsoid and then pick up nad83 it again
does not do Next and it is not clear what is wrong

--Not sure what is going on here. Can you give us more information to
replicate it?

At least the region issue and UTM search should be addressed before
release, I believe

--I agree about the UTM issue. The region issue is best fixable (if at
all) by seeing if we can create an error message more specific to this
situation. That is, you can't set the region for a location that is in a
GISDbase that is not the current one.

if I may take a wild guess: after selecting the ellipsoid try pressing the
spacebar in the text box (then delete it) and see if the [Next] button
lights up. It might just be a missing update notification.

I've fixed items #3 and #4 above in develbranch_6. Please test. If it is
OK, I'll backport to release branch and trunk.

Comment (by cmbarton):

I've fixed issue 1 above. If a location is created in an alternate
GISDbase--i.e., one that is not the current one--the user is not offer a
bogus chance to set the region extents (since this doesn't work and only
generates an error).

Please test in develbranch_6 r39311. If OK, it can be backported to other
branches.

Comment (by helena):

Michael,

thanks for the fixes - I tried it out and all items work at least for the
examples that I tested.
It was mostly about handling situations when the user does not make a
correct selection.
The search for EPSG codes now works great, I think the changes can be
backported and the ticket closed as fixed,
(I would still encourage others to try out the Location wizard with their
favorite coordinate systems
and try to make some typos too)

thank you,

Helena

I've backported these changes to develbranch (6.4) and trunk (7.0). Thanks
