More boundaries

I may have jumped the gun on the mapmask but I think the boundary idea is sound. I can always incorporate the masks in the future when they’re ready.

Some district boundaries are easier to decipher than others. The little ones like Soho, Leicester Square and Covent Garden are clearly defined by roads, so they’re simple to understand and easy to trace from Open Street Map.

Hammersmith and Fulham appears to be the borough of the same name for the most part, except there is a chunk carved out around Olympia and something odd happening in the north.  I think railways and canals are involved as nothing else seems to explain the northern deviancy.  It was easy until this section turned it into the hardest I’ve tried to set up so far.  Holborn-Clerkenwell is also an odd shape but at least seems to follow some sort of logic, albeit skipping between different borders and roads more-or-less at random.  It was harder than its western neighbours but relatively straightforward once the logic of it had clicked.

I’ve already noticed some errors I’ve made in placing listings between districts, so I am convinced that doing this has value.  It should be especially useful for casual users: adding a listing to Wikivoyage is probably the easiest microtask in all of the Wikimedia sorority but, if I’m having this problem even after trying to decipher the district map, then I expect it to be worse for others who have just turned up at a page for the first time.


A problem I’ve encountered a few times since beginning my attempt to upgrade all of the London guides on Wikivoyage is the boundaries of districts.  In particular, checking the project’s Inner London map against each guide, it’s often hard to reverse-engineer the logic behind these divisions.  This makes it hard to decide on which guide a listing should be placed.  It certainly seems to have confused past editors, as I’ve found several misplaced listings so far and a few duplicated ones.

A chance discovery looks like it can fix that.  While checking some details with an eye towards my first itinerary, which may not be up for a little while yet, I noticed the “Adding boundaries and tracks” section of How to use dynamic maps (which I have read before but never really noticed this bit at the end).   Apparently, I can use a GPX trace to draw a border around the area on the attached dynamic map.  Possibly the reason why I didn’t get this earlier is that it is largely unused at the moment: there were only sixteen maps (guides and itineraries) on the project using this function before I added my own.

Then, while exploring this system and trying to understand it fully, I came across another, complimentary function: the mapmask template.  It took a while to understand it; I thought the effect was generated by the previous function in some way but couldn’t work out how.  Eventually I found the template concerned.  This is actually used on fewer guides, eleven instances, and not all the same instances as the boundary trace.  The template uses the same GPX information but alters the map to slightly grey-out everything outside the boundary.

I think it looks quite good, and leaves no doubt about what’s inside or outside the district.  They could be used apart but I’ve used both for now, just in case.  I intend to roll this out to every guide for London eventually, although reverse-engineering the actual border from the map took a while here (it mostly follows the borders of the borough for a while, but leaves out half of it for another guide and annexes parts of Fulham and Westminster).  It might be even harder for some of the others.

Coping mechanism

I’ve found Cope to be the most confusing of the standard guide headings.  Most of the others are fairly intuitive… usually.  Buy could be subtitled “List shops here”, Sleep could be “List hotels here”, and so on and so forth.  Cope might as well be “Dump anything else here”.

The “Where you can stick it” page lists Cope’s contents as:

“Babysitting services, childcare, church/mosque/synagogue/house of worship (religious services), clinic, dentist, diplomatic missions (consulate or embassy), fitness center, gym, hospital, laundry/laundromat, library (unless it has good Internet facilities, then it can be placed under Connect), magazine, newspaper, pharmacy, police station, religious services, restrooms, toilets”

Meanwhile Article templates gives slightly contradictory information:

“This section is for common non-emergency services that the traveller might need: haircuts, babysitting, pet care, libraries, consulates, religious services, etc.”

At the moment I’ve put in some general supermarkets and emergency services (an urgent care centre and a police station).  The other suggestions remain a problem.

I have absolutely no idea what babysitting services exist in South Kensington and Chelsea, for instance.  There are a few thing I have found that match the list above but I’m not sure how useful it would be to, for example, list every individual public toilet, complete with geo-coordinates.  These things seem like a job for Google.

Looking at star guides for pointers doesn’t necessarily help.  Very few guides seem to bother having a Cope section at all.  The contents are so generic that I can’t imagine it was for lack of potential listings, so maybe it just isn’t seen as important.

I’d like to get each district in London as complete as possible but it might not be worth coping at all.
