comment Advice for Python with GIS
Please take the Tour to learn how our focussed Q&A format works because it is quite different to a discussion forum and other Q&A sites. I recommend this Meta answer for advice on how to structure your questions to try and attract potential answerers: meta.gis.stackexchange.com/a/3353

I suspect that there are null values in your hhfishing field now.

There is an edit button beneath your question which will enable you to remove the additional one to focus on this one and to provide more details about it.

comment How to create a plugin GUI for QGIS 2.8.2?
You posed a new question as an answer to this one so I have converted it into an edit. Would you be able to use the edit button to keep it as one question that is in sync with the existing answer, please? If it should have been a new question then you should perhaps accept the answer that has been given here and then ask it as a new question.

comment Measuring distances when crossing UTM zones?
@MichaelMiles-Stimson In my early days of GIS I worked on a project related to Port Pirie in South Australia that spans two AMG/MGA/UTM zones (but is largely in one rather than the other) and the advice I was given was that as long as we were within 30 mins (half a degree) of a zone then placing data into that zone would not introduce unacceptable distortion. I guess whether falsing into another UTM zone is better than switching to Albers/Lamberts will depend on how far into each zone the asker is wanting to measure their distances.

comment Transferring Attributes on the Same Layer
Welcome to GIS SE! As a new user be sure to take the Tour. Would you be able to use the edit button beneath your question to revise it with details of the GIS software (and version) that you are using, please? I think you should also include a few more details of how you do this manually and where you are stuck trying to automate the process.

I quickly edited a screenshot (from the link you provided) into your answer to illustrate that it is licensed at all levels.

comment Adding markers within constituency bounds using leafet.js and leaflet-pip
Welcome to GIS SE! As a new user be sure to take the Tour. To help make clear what it is that you are asking I recommend that you use the edit button beneath your question to include a single question mark somewhere within its body.

comment Fastest way to numerate intersecting polygons in ArcGIS
Polygon Neighbors does not need Advanced - for at least last few versions Basic is sufficient and I think since tool was introduced at about 10.1.

I think you should edit your question to include details of your Windows version and where your data is being accessed from.

Please take the Tour where you will see that there should only be one question per question.

comment Add comma to number labels, multiple records in attribute table
I don't think this is a duplicate because the earlier question used ArcGIS for Desktop while this is for QGIS. Their field calculators are sufficiently different that an answer to one will need considerable adapting before it can be used with the other.

comment How to search for fields in a GDB and add them if they don´t exist with arcpy?
Field objects have a type property so you just need to use that with if/elif/else statements to alter the type of field you add.

comment Unable to create multiple geodatabases in ArcSDE?
Welcome to GIS SE! As a new user be sure to take the Tour. Would you be able to edit your question to include the text of your error message rather than just a picture of it, please? That way it is available to future searches.

Perhaps focus on #2 on that list (which I left the sort=frequent off initially): gis.stackexchange.com/questions/7839/…

@Jeoff Please do not share details like your email address in posts (questions, answers and comments). If you are happy for people to contact you offline then you can place such details in your user card. meta.stackexchange.com/questions/431/…

comment same projections but different extents
I think that this will be due to one or both of the top two questions asked here about coordinate systems: gis.stackexchange.com/questions/tagged/…. I'm guessing that the first shapefile was digitized from a scanned aerial photo which had not been georeferenced first. It then appears to have been given WGS_1984_UTM_Zone_51N as its coordinate system when the units do not correspond to that and look more like pixels.

comment Fastest way to numerate intersecting polygons in ArcGIS
@MichaelMiles-Stimson I haven't run a test to confirm but I think that polygon overlay should allow the asker to dispense with the ArcPy cursor and thousands of Select Layer By Locations, to bring the time down to around 10-15 seconds in total. They owe you one. I don't think they are asking to do that last enumeration that you mention.

comment What is “steps” and “time” in ERA-interim
This does not seem to be a GIS question - perhaps it is suitable to research/ask on Open Data?
