comment Why do these points send me to the middle of the ocean or middle of nowhere?
@KylePennell everyone trips over this sooner or later, and probably more than once. Also we don't seem to have a canonical Q about standard coordinate pair syntax, or at least it's hard to find if it does exist.

User25105 you may not be able to upvote yet, but you can still mark @Xavikam's answer correct (which gives a bigger boost than upvoting anyway)

comment What kind of hardware configuration is needed for fast map services?
@blord-castillo, have you had a chance to update your thoughts for 10.1 (now 10.2.1?)

comment How to account for Colour Blindness when designing maps?
Looks like a good site, thanks :) --- Link only answers aren't very useful, inevitably the links break and then it turns into just one more dead end. A link with a name and context however is much more useful. See my edit for an example (and it is just an example, please feel free to re-work).

comment Choice of Cartographic Font
I have to respectfully disagree with my esteemed colleagues. Choice of typeface (font) in a map is as relevant as questioning whether to use hachures or a polygon fill, or improving visualization of overlapping polygons (see related questions at right). In any case, Robert: Are there any cartography "rules" you should follow when labeling maps? probably has what you're looking for.

comment How to extract common outline of multiple polygons with code?
Re-opened as per edit, it's the math theory and algorithms that are wanted here, not a ready made tool. (I question the wisdom of a project that aims to do geometry munging in pure php, but that's a different topic. If really you must use a web only environment, there is much better support for javascript; see leaflet, topojson, d3)

comment By converting into a shp file points are reduced
Hello, welcome to GIS.se :) You need to flesh out your question before we can help you. For example, what software are you using? and what features or tools of that software? and so on. Also a small example of the input data, or a link where it can downloaded, is also an aid.

comment ArcGIS - Custom, rule-based borders for polygons?
@ew_gis, I converted your answer to a comment because as it stood it was a link-only answer, which are generally not very useful in the long term. Your further comment, beginning to describe how one might prepare data to usefully use Symbol Levels for the OP's use-case begins to change that. I encourage you to flesh out the idea.

comment How to perform Full Text Search of Esri geodatabase?
I've accepted this answer as correct, because it works and got me to the end of my quest that day. However I'd like to note there is still room for someone to add a scriptable / programmable answer as well, as that would be very useful too.

comment The simplest way to uninstall any and all ArcGIS products?
I've updated the batch file for better maintainability, uses a text file for product codes & names now, and moved to GitHub 'cause more arcgis code lives there; uninstalls 10.2 desktop.

comment How to perform Full Text Search of Esri geodatabase?
@PolyGeo, hah! chalk one up for icon habituation blindness. I don't use that part of that toolbar, so it became background noise, and when I was looking for search tools, I'm reading the menus, and icons can't be read of course. For those with a reading bias similar to mine, it's the binoculars on the Tools toolbar. Leaving the Q open in order to give a chance for other possible choices (Find tool works but is terribly slow).

comment How can I retrieve a list of the most used GIS software?
if answers like what are coming in are useful to you and help with your project, then great. I'm glad it works for you. I was trying to point out, clumsily I guess, that what comes in will be very fuzzy and incomplete at best. (go ahead and prove me wrong though ;-)

comment How can I retrieve a list of the most used GIS software?
I don't think any meaningful numbers can be arrived at without being specific, defining scope. Most used... for what? making the little road maps found at gas stations? publishing atlases? putting mashups in personal blogs and home pages? filing quarterly business reports? putting gps tracks into a personal trainer app? And even once scope is defined, I anticipate what you'll receive is a lot of anecdote, a wallop of opinion, and precious little actual data. And, even if you do get a real answer, what would that do for you? How would knowing X is used more than Y change your life or business?

awesome answer! This would also (likely) be applicable to Site to download al USGS Topo Maps in bulk

comment Is there a programmatic way to retrieve Landsat 8 Satellite Images?
My answer for Site to download al USGS Topo Maps in bulk may help in constructing POST requests (though we'll have to wait for the US government to resume operations to find out).

comment Synchronize data edits between ArcMap and ArcGIS Online
@Blendt, I still get missing features from time to time when uploading new data to an existing feature service. I've tried both data synch tools (e.g. Windows Mobile) and just straight upload everything and overwrite the service. Some features just refuse to go. For what it's worth, I've opened a ticket with Esri Canada "arcpy.StageService omits features {[CASE#143409]}". There is progress but a not a solution I'm willing to trust on an ongoing basis. I've all but given up on ArcGIS Online for our needs. But that's for me, I encourage contacting Esri tech yourself, might be different for you

@ArditSulce, excepting that "goodal" is older than google. ;-)

comment Are there any cartography “rules” you should follow when labeling maps?
This answer is horrible to read. It should be filled with pictures and examples!
