comment Where can I download 1 arc-second elevation data for Canada other than Geobase?
@Jakub, see updated post for what I get. What data (NTS tile) was used for the image you posted?

comment Quantum GIS and ECW images?
that's curious, that ppa is where I installed qgis from. Oh, gdal-ecw appears to be Ubuntu Jaunty (9.4) only. libgdal-ecw is listed for Lucid (10.4) but results in "E: Couldn't find package libgdal-ecw". Sigh. Time to spend some more time digging in I guess.

what is the 1 arc second equivalent in meters? I always get that messed up. Also, can you be more specific about what is unusable about the results you are getting?

comment Discontinuous or Interrupted map projections?
thank you for the spit and glue, I may indeed have to chop this up and attack it piecemeal; I hadn't considered that approach.

comment How to create a Personal Geodatabase
the downvote, I surmise, is because creating a personal gdb for most is trivial in the extreme, analogous to asking "How do I create a new folder in Windows Explorer?" If as Kirk suggests he doesn't have ArcMap/Catalog that should be part of the question, e.g. "How to create a personal gdb through ArcGIS-Engine/ArcObjects/python/... and without Arcmap or Arccatalog?"

comment Discontinuous or Interrupted map projections?
-1 for mapproj, which (from the docs) only supports the single point form of Sinusoidal, "sinusoidal() equally spaced parallels, equal-area, same as bonne(0)". +1 for Myriahedral which is definitely discontinuous and looks interesting. The software used appears to be private though and not available.

comment No way to De-authorise ArcGIS Server? How to get license back?
Same here with ArcGIS License Manager for concurrent use desktop users. First round of authorizations went okay. Then we purchased some additional arcview and extension licenses. The second batch appeared to authorize okay, but a few days later "just disappeared" from the license pool. I had deauthorize everything and then add them all at once. In the third round, adding another extension license, there was an error message about having exceeded allowable number of authorisations and now I'm playing email and phone tag with ESRI Canada tech support. The new license system is buggy and sucks.

comment compound variables in model builder?
soo, it appears that actual answer is "you can't" :) This works, and I'll use it, but I might as well just skip model builder altogether and do everything in python. Thanks.

comment Legal issues with tracing a map from an image
Reading between the lines, the client may feel like they paid for the work already in acquiring the paper map and feel they're being held hostage for more. Perhaps this why you have the contract in the first place and not the map creator. Advise them to always ensure they get paper and digital deliverables in their contacts. This is something we too learned the hard way, and consequently invested a lot of money and resources re-inventing work in order to be free of future restrictions. For us, it has been worth the investment. Swallow the bitter pill now and be immunized.

comment How to get an address or location from Google Maps?
the drag marker example would be the perfect answer, providing simulataneous street address and coordinates in an easy to copy and paste form, if the marker was placed interactively initially. Perfect for anybody in Eastern Astrailia though ;-)

comment How to get an address or location from Google Maps?
aaaaah, it's not quite so bad: to get coordinates only remove all existing google map directions (decheck anything resembling "directions to" at bottom left). It's when multiple destinations exist that the precise coords are exchanged for the fuzzy "such and such road".

comment How to get an address or location from Google Maps?
this is fastest the most direct route of the answers posted. It is unfortunately unreliable in areas where the street address database is sparse or incomplete. Sometimes it will just pick the name of the nearest road, which may be many kilometers long, when coordinates would be better.

comment How to get an address or location from Google Maps?
In this use case I have neither street address or Lat/Long at my disposal. Just a screen I can point at and ask "where is this?"

Not enough detail provided to be an answer; I already asked if SAGA could be used for this, in a comment to the Q.

comment Are there open source alternatives to ArcCatalog?
gdal/ogr supports ESRI SDE connections, with some work, and ESRI personal geodatabases. See gdal.org/frmt_sde.html, gdal.org/ogr/drv_pgeo.html. So yes it is possible to add some ESRI formats to an open source spatial catalog browsing utility.

comment finding nearest point to a point
this would be a better answer if it included one such example snippet or conversation. We can't rely on links to external sites to remain intact, and if/when it does change this answer will become wrong.

comment Are there any “highly customizable” GIS platforms?
it's not as seamless or complete as a watch file, but the Results tab contains the history of your geoprocessing, which can be drag n dropped to Model Builder or exported to python snippets. I use this as a kind of improved metadata history for datasets.
