Historical view of openstreetmap

Posted by mapryan on 12 March 2013 in English (English)


Does anyone know if there's a way to see a historical view of Openstreetmap? ie, for a given area, can I see how it looked in OSM 6 months ago compared to how it looks now?



"UAV could map archeological sites in a fraction of the time currently required"

One of these could be really useful for all those areas with no or poor satellite imagery coverage

Island problem

Posted by mapryan on 7 August 2012 in English (English)


I've been doing a lot of mapping around Narathiwat in Southern Thailand. I had the coastline running into the bay in the city and it seemed to make more sense to cut the sea off at the mouth of the river and convert everything from there backwards to be river (and with riverbanks instead of coastlines). However, since doing that, the islands in the rivers have now all become blue and are not appearing on the map.

I figured it was something to do with the direction of the ways, but I tried changing these to no effect.

Is there anyone more experienced in these things could have a quick look and maybe work out what I'm doing wrong

Narathiwat, Thailand

Completed a lot of work on the town of Narathiwat in Southern Thailand. Been away for three years but I'm here on holiday and couldn't resist making updates given the complete lack of openstreetmapping that had been done.

Old GPS I no longer use

Posted by mapryan on 8 March 2009 in English (English)

Hi all

I upgraded to a Vista etrext HCX a while back, and have had an old yellow Garmin etrex 12 channel GPS sitting in the drawer doing nothing. I was going to stick it on ebay, but if there was someway I could contribute it to the openstreetmap project to help someone keen get mapping, I'd be happy to do so.

Does the project co-ordinate anything like this?



West of Alencon

Posted by mapryan on 28 February 2009 in English (English)

Staying with friends in a place called Gesvres, west of Alencon, so having lots of friends driving round virgin openstreetmap territory. They also think this is quite an intersting thing to do, as opposed to the usual reaction of "You're doing what?.....Why?...."

Streatham and Norbury

Posted by mapryan on 17 September 2008 in English (English)

Added loads more street names to the Streatham/Norbury area with my combination of 125cc trail bike, Garmin GPS and an iPhone to take the pictures.

It's great being able to load the geo-tagged pictures into JOSM along with the track, but I find that JOSM gets a bit confused if I take two pictures too close together (physically). Maybe it's the iPhone's dodgy GPS or it may be a problem with the JOSM geo-tagging plugin. Either way, it causes the photos to go out of step with the next one appearing where the last one was (if that makes sense).

Anyway, to get around it, I just make sure I take a good picture the first time every time!

Down side to all this setup when out OSM'ing, is I have to constantly leave one glove off to be able to get the iphone in and out of my pocket to take the pictures which could rule this out as an evening activity in the winter. Still, I may have all my local roads named by then 8-)



Location: Streatham Vale, London Borough of Lambeth, London, Greater London, England, SW16 5LJ, United Kingdom

Added street names between Leigham Court Road and West Norwood

Posted by mapryan on 7 September 2008 in English (English)

First time I've done mapping using mainly just my iphone (and my motorbike). Just took a picture of each street name using the phone then went through them using Josm and the AgPifoJ plugin. Seems to work well enough, but I found that if I added them all at once in JOSM, I got really confused about exactly which was where. However, adding them one by one made a lot more sense (I also noticed that the photo icon stays grey until you click on it, when it turns red).

One odd thing, is that sometimes the photos often showed up at the last location I stopped. However, I think this may be more an iphone problem than a AgPifoJ one.

The webpage listing the unnamed streets is obviously invaluable doing something like this

Balham roads with no names

Posted by mapryan on 1 September 2008 in English (English)

Went out this evening and grabbed some outstanding street names in Balham.

Also found a couple of streets not on there (must remember to go back and finish Bellasis Avenue off)

North of the Galtee Mountains

Posted by mapryan on 30 August 2008 in English (English)

Added loads of new roads in the area around Galbally, which is just north of the Galtee Mountains.

Lots of the local main roads are already mapped, but everything else seems to be missing. Sadly, I'm only around for 2 days, and I'm going home tomorrow. However, I'll be back at Christmas and will do more if it's still the same.

Driving around collecting GPS traces has made an interesting change from updating Openstreetmap in London. After all, most roads there are done and it's all detail now (street names, one ways, etc). Over here, it's like a big blank canvas.

Mind you, the amount of times I headed up a side road following a road, only having to do a u-turn as I find myself in someone's yard. (Invariably, 3 or 4 men will be huddled over an car's engine, and all give me a very distrusting look as I turned the car round in front of them). On the plus side, I only once found myself in a dead end that I had to reverse out of.
