Before I go and pay is there a free source for UK Postcode Boundaries, ideally down to Postcode Sector level ("AA00 0" or even better "AA00 0A")?

I am trying to find the shapefiles for postcode sector and districts in the UK. Specifically inside London. I know I can go and pay for these but I only really need to use them once. I want to generate my own mapping tiles with the shapes on one version of the tiles. Allowing me to show all the postcode boundaries without overloading the JavaScript on the client side.   I could "redraw" some of shapes myself (tracing from others) but would be great if there were some shapefiles already out there.   Can anyone help?

I am writing an application to performance test all kinds of map services, primarily AGS 9.x, AGS 10, and WMS 1.x.  Part of the application involves generating random bounding boxes for individual requests, within the service's full extent. This part is working fine for geographic and projected coordinate systems when the service's full extent is known (e.g. through an AGS service's fullExtent property).  My problem is with WMS: each layer in a GetCapabilities response can define its bounding area in >= 1 CRSs. Some parts of the application need to know if a service's CRS is geographic or projected, so in order to remove ambiguity in WMS I am always using the layer's LatLonBoundingBox which is always defined and in EPSG:4326. I then have to calculate a full service bounding box based on all layers that go into an individual request (which are randomised). This is where it gets tricky.  I am getting lost because for each lat / lon bounding box the LLx (lower left longitude) could be a larger or smaller number than the URx (upper right longitude), depending on which meridians it spans. Every time I start drawing square or circular diagrams I think I have an approach figured out, and then find a case that ruins it and my brain turns to mush.  I am going to keep thrashing at it until it works, and if I get a solution post it here, but I'm sure there has to be an accepted and fully tested approach which would make my life easier. I just can't find it right now.

I have been familiarising myself with QGIS and the free information Ordnance Survey provide. Though I'm struggling to find further data specific to my needs.  I want to produce a map plotting renewable energy in the UK (or at least operating wind turbines) against locations of operating data centres, preferably on a background of wind speeds.   Are there places where I access this data?  By so far I have seen only these sources:   This website provides locations of data centres:   This renewable energy:  This has wind speed but when I import it is all the same colour:

I'm interested in locating free GIS shapefile data representing the US / Mexican border. I have found a point layer depicting the border crossing points but I'm interested in a polyline feature representing the actual border.

Does anyone know how to find a shapefile with boundaries of Indian municipalities?   I have tehsil boundaries as for year 2001, but I would like boundaries of municipalities and, ideally, also historic ones.    I believe Census of India has the information but I couldn't find any maps or shapefiles...

This question dovetails with this post on .  I am familiar with some of larger, paid-for business registry's like  and .  While the detailed information their business listings database include (like # of employees, annual sales, industry code, etc) is fantastic, if you are on a limited budget, sometimes the cost of purchasing the data outweighs the value you can get from it.  If you have geocoding capabilities in house, one could potentially create a reasonable surrogate by spatially-enabling (geocoding) a publicly available business listing on your own.    If you were looking to take on this type of project, where would you start your research? Do you know of US agencies at a State or National level that maintain this type of information, AND are publicly available for download or minimal purchase?

I am looking for shapefiles or a list of suburb names for Melbourne and Canberra. I have ABS shapefiles, but I need to filter that to end up with only metropolitan suburbs.  My shapefile has codes in it for  - I just need to know which suburbs belong to the metros.

Please use UK pre-uni methods only (at least at first). Thank you.

I am using  to update the roads in OpenStreetMap. I have a copy they published last year and one that was just published, and I would like to find all the LineStrings that have either had their attributes or their geometry changed. This will assist me in making sure all the new and modified streets are updated in OpenStreetMap. The street segments should have a unique identifier, so my only thought is to write a Python script which opens both Shapefiles, finds any segments in the new that aren't present in the old (added segments), and the reverse (removed segments), and then loop over matched pairs comparing their constituent coordinates to see if anything has changed. Is there a way to do this using QGIS?

I live in the UK, and whenever I visit google.com I am redirected to google.co.uk, but I want to see my website's rankings on the US version (I presume the results are different). Is there a way to do this?

I do not seem to be able to find a free shapefile of the European countries. This is the kind of map I am looking to populate with my own data using ESRI ArcGIS:   The  only seems to have a shapefile of the region with country boundaries that also includes the NUTS divisions. Natural Earth shapefiles only seem to be available for the entire world, not for regions like Europe.

I just (December 12, 2018) downloaded the training manual and data. I'm trying to get started but I cant find the first part to download the OpenStreetMap part.  "In the Vector menu dropdown, select OpenStreetMap -> Download Data. You can then manually enter the co-ordinates of the region you wish to use, or you can use an existing layer to set the co-ordinates."  I see the Vector menu on the top ribbon, but the dropdown does not have the right option. I cruised around but didn't see a way to add it.

Is there a source for historical shapefiles of Europe in the modern era, i.e. starting ca. 1400?  I know that "where can I find historic border data" questions were asked multiple times but I couldn't find an answer to my specific question.

I have data that spreads across two UTM Zones GDA/MGA94 UTM Zone 55 and 56. I have layers such as a cadastre, roads, pipelines etc where I want to store measurements like lengths and areas in metres or some kind of metric notation, not degrees!  Whats the best way to manage this in PostGIS (i'm using PostGreSQL 8.4 PostGIS 1.5)?  Should I be storing my data as GDA94 Geographic coords and using some sort of work around to calculate the measurements I require?  Or is there another way to handle this?

I have an issue with American and Canada postcodes in accounts and contacts. Some of the users are creating the salesforce records with postcodes like (MD 20904), when we sending post code from salesforce to SAP integration, SAP system is rejecting salesforce records as postcode is not in correct format.   My question is:   what are actual US and canada post code formats? If Users are creating the post codes with MD 20904, how would prevent through validation rule like only accept sepecific format?

I am using QGIS v3.12 and projection EPSG:27700 - British National Grid.  I am trying to add a label to my map layout which will give the grid reference of the centre of the map as a UK 8 digit grid reference ( e.g. "AB123456" ).  So far I have managed to get the x and y coordinates using the expression:   Grid reference at map centre: [%round(x (map_get (item_variables('Map1'), 'map_extent_center')),0)%] , [%round(y (map_get (item_variables('Map1'), 'map_extent_center')),0)%]   Is there any function available in QGIS that can translate these coordinates into the required format?   Sorry my coding skills are not that great!

I am looking for a vector file worldmap which should include as many boundaries reaching to a very small level (like ZIP-Codes/small communities/etc) as possible.  The data of Natural Earth is quite good, but does not go that much in detail. The  data would be nearly perfect, but it is not allowed for company use.  Requirements:   Consistent boundaries for nearby countries (no overlapping!). As much detail as possible (refering to boundaries). Country boundaries and subdivisions should be separated. The data is for company use, therefore I should be able to buy it, or it should be free to use for companies.   I also thought of extracting it from the OpenStreetMap data. Do you think this is possible?
