comment PostgreSQL StackBuilder 3.1.1 error
There does not seem to be a GIS component to this question. I think you should consider deleting it from here and researching/asking it at DBA.stackexchange.com instead.

comment arcmap buffer geoprocessing range error
Would you be able to copy/paste (or re-type) the precise error/warning message into your question as text, please? The picture is useful too but will not show up in a search. Would you also be able to include the precise parameter values that you supplied to the buffer tool, please?

comment Geoprocessing tool for finding specific point within polygon
@user1269942 I'll re-phrase - that tool starts with a known point whereas this question is about determining the XY location of the point that determines the largest circle that can be drawn inside the polygon.

comment Geoprocessing tool for finding specific point within polygon
@user1269942 That tool sounds like it looks for the nearest polygon that the point is outside of rather than maximizing the size of a circle from within.

comment ArcGIS Solar Radiation tool says output global radiation raster empty?
If you have additional information that helps clarify your question in response to questions asked I would recommend using the edit button beneath your question to keep revising it. Including things like the precise inputs that you fed to the tool would most likely be helpful here.

comment Best sites to create a collaborative map?
I think it is worth looking for ideas under the crowdsourcing tag.

comment How to convert polygon singleparts to multipart?
You're right - I had overlooked the significance of that sentence in your question and have not used that QGIS tool. I'm keen to learn the outcome of your test because, as I said in my answer to the other question, I could see no logic in the limitation being in place for the ArcGIS platform. If you are able to create the desired multipart polygon with internal boundaries using ArcPy I am curious to know whether it can be drawn in both QGIS and ArcGIS for Desktop, and whether it passes the Check Geometry tool test of ArcGIS for Desktop.

comment Add Marker on the polygons' centre using Openlayers?
Please do not ask the same question on more than one site in the Stack Exchange network. If you perceive a need to then review meta.stackexchange.com/questions/234495/….

comment How to convert polygon singleparts to multipart?
I just updated my answer at gis.stackexchange.com/a/63065/115 to clarify that I think this is a limitation of shapefiles and geodatabase feature classes i.e. it seems to be independent of whether they are written by a product/component from the ArcGIS platform, Python, or another GIS vendor or open source GIS project.

I agree with @Erica - this sounds like a duplicate of the question she cited.

@Menno I recommend that you write up a quick answer of a few lines, which it sounds like recurvate would be happy to accept.

comment why use openlayers with mapserver?
Welcome to GIS SE! Something that we advertise in the Tour is that our focussed Q&A format works best with one question per question. I recommend that you edit yours to leave just the one that is most important for you to have answered first, and then research/ask the others separately.

comment Finding duplicated Parcel according to two fields?
@Ahmadsaleh If you have any follow up questions they are best researched/asked separately. As someone new to our focussed Q&A format I recommend taking the Tour.

@nmpeterson & Erica - I may have closed this as a Duplicate prematurely (based on Erica's close vote) - do we need to re-open?

comment How to delete last part of a string starting from the 1st non numeric character?
Despite being used in the Python Parser of the Field Calculator of ArcGIS for Desktop, this looks like a pure Python question that would be better researched/asked at StackOverflow.com.

comment Seeking options for Spatial ETL (Extract, Transform, Load)?
This does not appear to be an answer to the question so it will be converted to a comment. You may want to consider posting a new question for it.
