Mar 28	comment	Synchronize data edits between ArcMap and ArcGIS Online Thanks to the threads linked to above, I did get menu options to both "Edit local copy" and "synchronize" from Arcmap. The results were not good however. Somehow the GlobalID's for pre-existing features were turned to 0s, and the new point features I digitized had attributes but no visible geometry; the attribs did sync between local and server. After some more work & testing I'll post my results.
Mar 27	comment	In an ESRI Shapefile, what is the “Record Number” field of each record header in the .shp file? You don't indicate why the question is interesting to you, but if it's in a programming or reverse engineering context studying the Shapefile C library (Shapelib) is likely time well spent.
Mar 26	comment	Why can't I import arcpy? Also see gis.stackexchange.com/questions/27058/…
Mar 26	comment	How do I export symbology to ArcGIS Online? the link is broken. The menu navigation path is still correct, for interactively managing the symbols after the layer is present online. It doesn't address exporting or transferring the symbols from Arcmap to Arcgis Online.
Mar 26	comment	How can I download a feature class from an ArcGIS Online web map? The menu path you note, "Add >> Create Editable Layer" does not exist for me with the Arcgis.com Map Viewer. All I get are options to add a layer from web, shapefile, csv. I do have "Add Features >> More >> Create Layer >> (select from template)" in Online Explorer, and when I do that and save the answer provided by @artwork21 works.
Mar 22	comment	How to find the minimum extent of a given pixel value of a raster? good point about local folders, and thanks for the quick background fix (much better than writing instructions for everyone I pass it to). Might be worth throwing this up on bitbucket/github/gcode/etc.
Mar 22	comment	How to subset raster image using gdal? @hardik, `gdal_translate` is written in C++ and operates independently of the gdal python bindings, here's the code: trac.osgeo.org/gdal/browser/trunk/gdal/apps/gdal_translate.cpp. It's part of the core utility set and a compiled binary is generally installed by default (unless you're not installing and only building from source).
Mar 22	comment	How to find the minimum extent of a given pixel value of a raster? Very nice Luke. Self contained, runnable, uses in_memory, and well commented to boot. I had to turn off background processing (Geoprocessing > options >...) to get it working.
Mar 21	comment	Has ESRI made any definitive announcements about 10.1 SP2? Ouch, that's a nasty bug. I would holler loud and long at our Esri account rep and at tech support and if it were affecting our operations. Ask for a hotfix. Thanks for bringing it to our attention (and Welcome to GIS.se!). I still have to -1 the Q though, because it's of time limited nature and shortly will mean nothing.
Mar 5	comment	How to use directional shading on boundaries for cartographic effect? is it possible to link to a large image? I'd like to study the detail more closely
Feb 14	comment	How to set QGIS Python path so that I can use system packages on Windows? @gmacfarlane I've no idea. It's worth asking as a separate question as the Mac answer will be very different.
Feb 14	comment	The next big thing in standardized spatial data exchange format? thanks @blah238, I edited to insert the related SE discussion as it captures the background conditions well. I may write my own answer later this week if no one else does in the meantime. I've run out of my SE time quota for now :)
Feb 14	comment	The next big thing in standardized spatial data exchange format? To be fair, before I finished composing my question I stumbled across the answer by accident, but since it was hard for me track down I figure it's worth recording here for others. In your answers please do more than just post the name, a copy-paste blurb and a link. Txs.
Feb 1	comment	Is the term “Quantum GIS” trademarked? Tim, you say "not yet", does that mean you (plural) intend to undertake that at some point?
Feb 1	comment	Tablet or smart phone GPS vs “real” GPS sounds encouraging. It'd be nice to have some articles about it which aren't a press releases from the company(ies) involved; perhaps in the fullness of time that will come. :)
Jan 30	comment	What is the simplest method to add GPX files into Arcmap? +10! Full OGR support in Arcmap (and all arcgis?) would be extremely awesome Ragi. Even more so the advertised "...in the next ArcGIS release, WorkspacePlugin's will have write support". And open source to boot!!
Jan 29	comment	Tools to compare unversioned copies of geospatial data I contacted the author of Differ, who said there are no updates for 10.x environment, and implied he'd take it offline if he could, as he doesn't intend to support it. He also pointed to the Data Comparion Toolset as something which works in the same problem domain.
Jan 29	comment	What is the simplest method to add GPX files into Arcmap? While I agree that Qgis has long had GPX support and using it is smooth, this question is about Arcmap, and so this answer is off-topic ;-)
Jan 28	comment	The simplest way to uninstall any and all ArcGIS products? thanks for reminding me about python modules @blah238, I added an answer to help with that.
Jan 28	comment	The simplest way to uninstall any and all ArcGIS products? Thanks @Brad. I didn't test TerraGo, their site has many broken web pages at the moment; ETTools 10.2 for 10.0: uninstalling out of order worked, but I'm guessing that since they have their own uninstaller to fix out-of-order removals, ian-ko.com/downloads/Uninstall/ETUninstall.exe, they've tweaked the main installer to work around this problem.
