comment Interactive “For each … Do” loop?
thanks Sean. This route is not as direct as one might wish (I'm pretty good at wishing!) but it did get the job done.

comment Interactive “For each … Do” loop?
thank you for reminding me about Librarian! In years past I spent many many hours constructing and using Arcinfo libraries, and visit was a blessing. In this case I ended up building a model as per Sean's answer. It would have been faster to use the library though as I actually have one already built with this index. Doh!

comment Interactive “For each … Do” loop?
I needed to change iface to qgis.utils.iface (maybe that's new/specific to qgis 1.7?), but that's as far as I could get as the "QgsGeometry Class Reference" is over my head. It does answer the nub of the Q though, thanks Pablo.

comment Removing overlap in raster using Erase command line?
clarification: the 'blend' and 'mean' options for the mosaic use a weighted distance average, so the farther to the interior you go the less effect the other raster has. There is no user control over the wieghts or distance though.

@kirk, it's for desktop.

comment Removing overlap in raster using Erase command line?
how would you create the extent polygon for a raster which includes a nodata collar? (e.g. the image is rotated and a straight min/max of extent coordindates is inappropriate).

@kirk, yes we can assume the selection is already in place, whether by pointing and clicking or select-by-attributes or some other means.

comment Removing overlap in raster using Erase command line?
the mosiac tool doesn't help in the case where you want both of a) smooth blending at the edges of overlap and b) don't want blending of pixel values in the interior of the overlap. One must choose to either blend or have one of the inputs win.

I had a hard time selecting a tag for this. Feel free to expand/replace.

comment Has QGIS 1.7 been released as a stable version yet?
s'alright ;-) in the grand scheme it's a small misstep

comment Has QGIS 1.7 been released as a stable version yet?
This question is too ephemeral. In days or weeks it will be meaningless. It would be better discussed in chat.

it is of course your perogative, perhaps you just really like nice round, complete and green numbers {grin}, but there is no directive like "thou shalt strive to accept an answer for all questions!"

comment Is there a decent open source map-editor?
this should be merged with gis.stackexchange.com/questions/10071/…. Even though this question is older, the newer version has better answers. (In my opinion this shows the our community is growing, getting better through time, yay!).

comment Open Source Map Composing Tool
GMT is a quality toolset which deserves larger mindshare. It has been around a long time (1988) and has a large library of features, and (I believe) the single largest collection of projections in it's library.

comment How to work within ArcGIS image server export limits?
thanks Mapperz, but changing the server config is not what I'm after. Firstly, I can't do it myself, and second I don't want to comprimise the server's availability or performance for others. The question could be worded more like "work within export limits" but I can't think of a way to phrase it that doesn't make even more confusion!

comment How to work within ArcGIS image server export limits?
"smaller exports and combine afterwards" is exactly the idea, though (semi)automated is what I'm after. The actual pixel dimensions are irrelevant, though you're right 10k is large. In this use case the source image is 4 terabytes and the area I need to export approx 63gb (uncompressed).

Oohhh, that is the reverse of what I understood. In that case You should add that to the question.

comment Permanently reorder fields in data (shp, gdb)
I meant dbf limits, thinking specifically that csv has no limits on field name length or record value lengths, and that starting point was file gdb, but re-reading the Q I see "shp" is mentioned in the title. So, limits all around ;-)
