JOSM won't start up after Java update.

Posted by Marcello on 9 December 2021 in Dutch (Nederlands).

Yesterday I was prompted for a Java update, which I did. Now, however, JOSM won’t start anymore and gives the message that javaws.exe, which is used in starting JOSM, has been changed or moved. That’s a first after a Java update, so I’m lost for now. Anyone have an idea ?

I have Win10, the latest JOSM - and the latest Java (well, er, I think…).

thanks in advance,


Relation area calculator.

Posted by Marcello on 14 September 2021 in Dutch (Nederlands).

A superb tool devised by Thilo which I use to fix relations rather than really calculate their area, to be honest. But my bookmarked page goes to a ‘Not Found’ currently. Did I miss something ?

Route relations (an AustinHuang invention, I thought) shows up a blank page. I hope both are easily fixed by redirecting as I both like them very much.


Topomap and Histor's renderer broken ?

Posted by Marcello on 27 March 2021 in English (English).

Is it me or is there only one renderer (the standard ‘Mapnik’ -like style) active ? It looks like both Topomap and the ‘Histor style’ renderer are not active.


Unresponsive part of screen in edit mode.

Posted by Marcello on 14 August 2020 in English (English).

This may be a strange one:

When editing, the upper left part of my screen is totally unresponsive. When i move my mouse to that part, objects do not ‘light up’ to be selected, nor can I connect points there. P2 has this issue, ID strangely not; the graphics on my laptop prohibit me from using JOSM. Is this my (not too new) laptop starting to desintegrate or something else ? Anyone has an idea ?

Has the coastline update process stopped ?

Posted by Marcello on 25 April 2019 in English (English).

All my edits are visible pretty fast, thank you. But updates I did to ‘my’ (part of) the coastline do not show at all, even those I did over a week ago. As I know the process of updating the coastline is separate from the main update process: is something the matter there ?

edit: Topo map does update, Histor-style does update. Only the ‘standard’ view does not. Wot ?

kind regards,


(p.s. the region is AR120-17; about here: I can see both in P2 and ID that the coastline is (much) more detailed than shown, and I can find no apparent errors)

Renderer strike ?

Posted by Marcello on 16 November 2018 in English (English).

Am I inpatient or is the renderer on a strike ?


edit: it’s me being impatient. So much for a Friday evenng.

Rendering of 'farmland'.

Posted by Marcello on 1 October 2018 in English (English).

May I for once (hopefully) express my extreme displeasure in the recent change of OSM / ‘Mapnik’ rendering for ‘farmland’ ? I know there has been a discussion on GitHub, I know there is a (for some) valid reason regarding confusion of colours for social amenities and farmland, but still…

My point is this: I model a tropical island. There, farmland is rarely vaguely green, as rendered now, but often a vibrant yellow. And larger patches of farmland in moderate climates now almost look like the default background colour.

I know ‘mapping for the renderer’ is an ultimate sin, but f#*k it, I’m trying to make ‘my’ turf look good. For me, OGF is as much art as it is skill. The sudden change of my plantations from sort of golden glow (sugar cane, anyone ?) to a decrepit ‘vomit green’ is realy annoying - even if I have to accept it in the end.

sorry for ranting, thanks for letting me blow of steam ;-)


Tile renewal slowdown ?

Posted by Marcello on 22 June 2018 in English (English).

Is it my (seriously old Win7) computer finally dying or do we have an issue in tile renewal ? Changes done a good 5 hours ago show not or only partially.


Rendering engine slowdown ?

Posted by Marcello on 10 November 2017 in English (English).

It may be me being impatient, but do we have a rendering engine slowdown ? Even very small edits (and not coastline-related, for that matter) more than 5 hours ago do not show up .

And I was just planning to move a complete section of subway, imagine…


The Nuevo Espiritu adoption plan.

Posted by Marcello on 13 June 2017 in English (English).

As my larger neighbour city, Nuevo Espiritu, was a ghost town of less than half a dozen of roads until now, I have taken up plans to adopt the area. If any user feels it was or is ‘his’ turf, please say so - there was no development for over 6 months, so I took the liberty…

I started by giving Nuevo Espiritu a well-deserved train station, and then a station square, and then a small tram line which grew into a somewhat larger tram line and… You probably all know all too well where that ends. So in the end I will ‘do’ the whole area, and do it as good as I can.

‘Old’ Espiritu, the small settlement on the eastern cape, is supposed to have grown around the old castle, conveniently commandeering the entry to the bay. It is supposed to be your ancient village, small streets and alleyways, probably good tourism potential. I have thrown in a pair of nice beaches for the locals.

Nuevo Espiritu, connected to the old village by tram line T11, has grown into a medium-sized harbour city, thanks to a protected site in the bay. (lagoon ?) It has good potential for a lot of interesting stuff. I have given it 2 tram lines already, next comes the harbour area and detailing of the city center. Later the suburbs will follow (relatively dull work). In the end I might give it a small airport at the western part of town.

One question about tramway planning: I have seen that in 2 of the largest transit systems (Kaiwoon and Latina) the tram tracks are mostly laid besides the road in what looks to be on the sidewalk / pavement. I there a reason for this ? I have - so far - put the tracks either in the street itself (traditional street track) or on reservation in the median strip of larger two-lane boulevards or besides the road. That looked more prototypical to me.

Any idea’s / suggestions wellcome.


p.s. Does anybody know why my ‘new’ eastern neighbour, Arancia, has no railway station ? No, I’m not planning to touch it, it’s nice and someone else’s - but it just is strange for a city that size.

Hello there !

Posted by Marcello on 31 May 2017 in English (English).

Just for introducing myself: I am a fiftysomething mapper form NorthWest Europe. I have been drawing maps on paper from childhood onwards and am now happy to do this modern style.

I map on a very small (20 by 20 km.) part of West Commonia: the county of Santa Maria del Mar, which is no more than a former small-and-scenic fishing village gone touristy and some extremely ugly new development area near its train station (really meant to be as horrible as posible - thats versimilitude for me).
