Something similar happened in Ireland, the other place I sometimes map trails in OSM. Not so long ago, information about outdoor trails in Ireland was conveniently gathered at irishtrails.ie - about the coolest possible URL for the subject matter. And they threw that away!

Now that information is buried several layers deep in the hierarchy of sportireland.ie. - you'd hardly notice it on the home page. To be fair, at least they did set up redirects at the level of individual trail pages.

A frustrating aspect of maintaining hiking routes on #OpenStreetMap: hiking organisations seem to be especially unaware of the maxim that "Cool URLs don't change".

At some point the Andalusian outdoor sports federation changed its website from fedamon.com to fadmes.es, without redirects. Updating an OSM link to trail info requires searching the new website and hoping it still has the same name or reference. Some PDF trail descriptions seem to have been completely erased from history.

One thing I hadn't really appreciated until now is the way good mapping of buildings and addresses helps with POI mapping - even though they can be mapped independently in principle.

In Málaga where these things have been thoroughly mapped from official sources, I was able to place new POIs very accurately while surveying, using Everydoor with OSM as background.

In Almogía, with nothing but a vague residential polygon, I found had to adjust a lot of positions at home later.

While using the "mapping party" tool to produce the "before and after" map above, I was amused by the contrast between my map and the examples used by @gedankenstuecke to illustrate use of the tool.

Venado Tuerto in Argentina is all straight lines and right angles. Almogía has hardly a single example of either of those things. In fact one of the other shortfalls of the existing mapping was that several mapped streets turned out to be flights of steps.

The difference in the "before" and "after" maps may not look spectacular here. But a couple of hours walking around a village mapping these key amenities is arguably a more important contribution than adding another missing hairdresser in a big city.

In 2024 I did a lot of mapping of urban POIs in OSM. While I was worrying about 50% of potential POIs being unmapped or mismapped in a big city, rural areas have a much bigger problem.

Only 20km away, for example, the municipality of Almogía (population around 4k) was a POI desert until recently. The local health centre, bank, post office, library, and schools were all missing in OSM. So I tried to map as much as I could before starting a long hike.

It's always nice to add a newly opened piece of pedestrian infrastructure to OSM. In this case, the Sendero del CAU in the Mangas Verdes neigbourhood of Málaga.

Of course adding brand new things does mean working without the benefit of aerial images. I should probably change some bits of scrub to park or garden, but when I was taking photos I didn't think of identifying the boundaries.

Also as part of mapping these recent hikes, I've been trying out uploading some of my survey photos to #Panoramax via @MapComplete - mainly of guideposts and information boards/maps. Previously I only used this kind of photo to inform my mapping, without sharing them. But it seems kind of a waste to leave them sitting on my hard drive.

Of course the danger is that I'll now start worrying about the lighting and composition of what used to be mere throwaway survey snapshots...

A nice thing about these connections is that they allow me to indulge my hobby of devising long linear hiking itineraries using public transport to connect the start and end points.

One of my walks started with the first train of the day from Málaga to Cártama (point 1) and walking about 24 km to Almogía village (point 2), arriving just in time for the last bus to Málaga. With a bit more daylight later in the year, an even longer walk would link to the more frequent city bus network (point 3).

Following a couple of days walking around Almogía over the Christmas break, I've added 3 local signposted hiking trails to OSM.

I'm especially pleased that OSM-based outdoor maps will now show connections between the Camino Mozárabe to the east and the PR-A 293 to the west, via the summit of Santi Petri. Both were already mapped, but until now it was difficult to be sure from online information if there was a waymarked route between them.

I see Renfe is once again tinkering with the timetable on the Algeciras - Ronda - Antequera Santa Ana line. From 7 January, the last Media Distancia train in both directions will depart about 1.5 hours earlier.

For smaller stops not served by the Alvia to Madrid, this means the last northbound train will leave very early (e.g. 15.06 from Jimena de la Frontera).

... unfortunately, the only official connection from the last MD of the day to Málaga requires a wait of 1h37 on Antequera Santa Ana, a station whose only facility to speak of is a car park.

I guess one way to guarantee a connection is to allow more than 1.5 hours of slack...

Renfe says this change is to allow guaranteed connections to other cities in Andalucía. In typical Renfe style, working out what these exciting new connection possibilities might be is left as an exercise for the reader.

Perhaps they mean Málaga, the provincial capital for most places on the line, and with relatively poor road connections so that a decent rail service could offer competitive journey times. And in fact did just that pre Covid via a direct daily Malaga-Ronda return service.

Not a good start to the year for Renfe.

The software in their Series 106 (Avril) trains, which started operating in 2024, is apparently unable to cope with the change of year to 2025 - admittedly a development nobody could have been expected to foresee. Turning them off and on again doesn't seem to have helped.

The whole S106 fleet was out of action today, and no date has been announced for their return.

UPDATE: reported to be fixed for 2 Jan

A random bit of road theoretically taggable as "sidewalk=both". I came across it while hiking, at least 2km from any paved road or buildings.

I say "theoretical" as I'm not confident that all apps based on #OpenStreetMap would understand "hazard=bottomless_pits_at_random_intervals", so I opted to pretend there were no sidewalks at all. It's not like they are necessary here anyway.

I suppose there is a story behind this of a property development gone horribly wrong - probably pre 2008.

@amapanda @gedankenstuecke @dcapillae Zooming in even further in time in space, this one shows a small area over the last 6 months. The GIF is at zoom 18, and the side-by-side image at zoom 19.

This illustrates something I wrote about previously - when I started focusing on mapping POIs I found many unmapped shops on side streets (mainly towards the west here). Main streets (the single yellow street) often had about the right number of POIs but needed updating, as shown by the flickering icons.

I've been playing with @amapanda 's "mapping party" tool, in the version by @gedankenstuecke which allows it to be run in a browser without needing to install anything - see

https://tzovar.as/map-comparisons/

I like this example of a neighbourhood in Malaga over 2 years, as it illustrates two different kinds of mapping effort. The western part mainly shows detail add by @dcapillae to the park and cemetery, while changes to the east are mainly my POI updates I've posted about previously.

One thing relevant to OSM that is that Mijas identifies its trails quite differently to its immediate neighbours.

All the municipal trails in Benalmádena follow the standard Spanish system of PR (yellow-white) and SL (green-white) route numbers and trail blazes.

For reasons unknown to me, the otherwise similar trails in Mijas have no route numbers, and are blazed with a different colour for each route. I hope they won't decide to standardise and re-paint everything after I finish mapping...

I have hiked in Mijas several times, but often at the end of long a long and tiring hike from other parts of the range. So it was a nice change to focus on the purely local trails.

Today's walk was a simple slog up to Pico Mendoza (1050m). I always find it hard to get my ahead around the fact that modest-seeming summits like this, accesible via a fairly casual hike, are higher than the highest peaks in my native Ireland.

I've posted a lot about POI mapping recently, but it's time to return to one of the first things that got me interested in OSM: mapping hiking routes.

Last winter I systematically updated the waymarked trails in two municipalities that share parts of the Sierra de Mijas: Torremolinos and Benalmádena.

The weather has cooled enough for me to take this up again, this time in the municipality of Mijas. There are 5 local trails without route relations, so plenty to be done!
