comment How to select polygons by distance to a single polygon in another layer?
A strong +1 to your comment about adding the "Within distance of" option to the spatial query plugin. That seems like a basic facet that GIS software needs to be able to handle without first creating a buffer layer of your features.

comment WMS Layers from Azure Geoserver not loading with multiple users
There is a config option for the maximum number of connections to the database. Have you checked this? It could be that it works until it hits this number then starts to fail.

comment MySQL Query in WAMP
Hi, and welcome to GISse. I think an answer to your question exists, but there are a few different ways it could be approached. To help find the best way, it would be helpful if you would narrow it down a bit. When you say the last row from a MySQL DB, would I be correct in assuming there is a particular table that you want to return the last row from? If so, then what do you mean by last row? Last row entered, or by date, or by a particular attribute? The more detail you can provide about your problem, the more likely it will be that someone may have an answer. Good luck!

comment QGIS, connect to postgresql using windows login credentials
Given that the link @Mapperz provided is to documentation on the PostgreSQL website, and provides instructions on how to do what you ask, it is not a guess. Also, at the end of the document, it states that psql does not verify the certificate, not that it fails to connect.

comment Change the actual coordinates in a shapefile (QGIS)
@spencer_f - Given that the shapefile was showing offset prior to any exports, I would first go back to the source and ask them how the data were created. Calculating a shift is great for the short term, but it may be that there is an unknown issue at the source that could be corrected, thus preventing future issues.

comment Unable to add feature class based on database view in ArcMap
Could you post some details about the particular database backend you are using? Also, perhaps the sql from the view that was created, and a screenshot of what you see in ArcCatalog would help visualize the actual problem. There are a number of areas that might be having issues, so the more detail you can provide, the better. Also, what projection is your data in? Does the view that was created have a unique ID field?

comment Change the actual coordinates in a shapefile (QGIS)
Welcome to GISse! A few things. You received the file as a shapefile from someone else and were using it in QGIS. Did it work fine in QGIS, and by this, I mean, did it overlay with other data properly? Where did the data come from? What projection is it in? When you exported from QGIS, were you actually doing a coordinate transform to Lat/Lon as part of the kml export? Have you spoken to the people who provided you the source data? These are a few things to try, as well as additional information to provide in your question.

comment How do you create a buffer for a specific feature in QGIS?
Also, perhaps a caution from looking at the image you included would be to make sure you have the "Distance" field set properly. Right now it is set to an OBJECTID_1 field, which unless you chose it just for a test, may give you some undesirable results.

comment Why is my KML file too large?
Where are the polygons coming from? How are they being generated? As you've said, when you remove some polygons, the kml works properly, so the format or syntax is not a problem. That leaves an issue with the features themselves. I would look at your program to see if you are getting a polygon that is created with an inadvertent loop or something in it. The more detail you are able to provide about the source of your data, the more likely that someone may have an insight into a solution.

comment Why is my KML file too large?
I think you might be missing something from your own explanation. It seems pretty clear that this isn't a size issue. Your file is well below the allowed size. I think it is an issue with one or more of the features. If the file uploads properly when you remove most of the polygons, that would seem to indicate that the issue is with one of the polygons removed. It sounds like you need to do more testing of your polygon features. If you don't have an idea of which one is the culprit, a thorough way would be to start with the layer that works and add one more at a time to upload and test.

comment Why imported mdb database doesn't show any polygons
Is this MDB an Esri Personal Geodatabase? Essentially, you need to make sure that the tables in the mdb that contain spatial information are registered as such by ArcGIS. This would include ensuring that they contain an "OID" or "FID" field with a unique ID for each record. An easy way to tell how ArcGIS sees this database is by looking at it through ArcCatalog. When ArcGIS identifies a table as containing spatial data, it assigns a point, line or polygon icon to that table. Otherwise it will have a generic icon, indicating attribute data only.

comment Intersect two same extent shapefiles, but got error 000117
It may also be an issue with geographic coordinate vs projected coordinate systems. Have you tried projecting each of these layers to some coordinate system, then trying this?

comment Intersect two same extent shapefiles, but got error 000117
As @AndyBradford mentioned, it sounds like you may have no overlap. It might help to post a screenshot of the two layers, as well as a bit of descriptive information about what they represent. As well, are you able to run other spatial operations on them without returning an error? Issues with other functions may indicate a geometry problem with one or both of the layers.
