As I'm only likely to do this process once or twice a year I'm caught in that "is it worth expending ages learning something now to make this simpler?" Possibly not.
If it looks too fiddly then I may well have to carry on with my manual process. Here's a post I wrote previously (with pics and worked examples) on how I used Google Fusion / tables to map UK cinemas, for the Sherlock special.
Is it easy to map a list of postcodes to London boroughs?
If it's fiddly and difficult then that's no good because I already have a low-res working method. It's just inefficient and non-shareable. I have an unshakeable belief that lots of people have probably wanted to do this and someone must have already come up with a solution for the non- or only mildly-technical user.
I have a list of 100 London schools' postcodes (it could be 10, 50 or 2,000 as this needs to be scaleable for others to use) and I would like to display them on a map that says something like: 4 are in Harrow and 16 are in Greenwich, with a magnitude indicator of some kind. I might get it to do "if fewer than 5 show as blue", "if more than 5 show as green", "if 5-10 show as orange" etc). In fact I can do this fine on a PC with a bitmap file of a black and white line drawing of boroughs (using the fill tool on free Paint.exe, no idea what free tool works on a Mac).
Currently I can, with ease, use Google Fusion tables to convert a single column of postcodes to a geocoded map. It looks like a map with one red (the default, can be changed) dot per postcode.
(b) see if I can get Google Fusion to combine SE1 1AA and SE1 2ZZ into "two in Borough X" - my workaround is to add a column and write in the borough, re-order and count them and then have two columns with the borough name in one and the number of times it appeared in the other ("Lewisham, 2" / "Barking and Dagenham, 1")
(c) make the raw file available (without my postcodes which are my data) to anyone else who finds themselves with a list of London postcodes and a desire to map them in this way.
Is there a pret-a-Fusion look-up table or a ready-made-London-borough-map that will work with a Google Fusion table of postcodes that I can ust add? I did look but couldn't find it, nor could I understand what I could find ;) I don't really know what KML or SHP files are.
- Is it possible to add a Polygon layer to a google map v3 without using fusion tables (2013) - this is too technical for me and seems to involve using APIs and KMLs and I have no real familiarity with either
- Map of London boroughs - but I've no idea how to add my data to it
- London Boroughs - Boroughs KML - looks interesting but no idea what to do with it
