Re: [Mapnik-users] Customising footway rule in osm.xml wrecks all the ways

2008-03-01 Thread Nick Whitelegg
Hello, I'm making a customised map based upon OpenStreetMap's toolchain and osm.xml. I want to, amongst other things, distinguish between official and desired footways. I've used the tag status=desired to denote the latter. When I change the footway rules to reflect this I get really odd

[Mapnik-users] Fw: Mapnik viewer for OSM data - UI suggestions?

2008-04-25 Thread Nick Whitelegg
Hello everyone, One of the OSM projects I'm hoping to work on is a Mapnik GUI renderer for .osm files (and live API data, cached locally, and PostGIS databases), based on the Mapnik viewer. However what would be good is to get some user interface suggestions from people. The aim is to try and

[Mapnik-users] Compiling latest Mapnik and OSM plugin on Mac OS X 10.5 - experiences

Hello everyone, Got the latest mapnik (checked out Wednesday night) compiled on Mac OS X 10.5 with boost 1.37 (macports), but did encounter one or two things not on the wiki page so thought I'd share them. Firstly, couldn't get mapnik 0.5.1 to build, the SConscript couldn't find the boost shared

Hello Dane, Interesting. What were the compile commands needed to built it? I used the following: g++ -I/usr/local/include/mapnik -I/opt/local/include -I/usr/X11/include -I/usr/X11/include/freetype2 -I../../agg/include -L/usr/local/lib -L/opt/local/lib -lmapnik rundemo.cpp -o rundemo

[Mapnik-users] Cycle map Mapnik XML file?

2009-02-11 Thread Nick Whitelegg
Hello everyone, Is the cycle map Mapnik XML file available? Would like to know wht the projection string is to produce a Mercator projection from WGS84 lat/lon input. I think Artem might have told me at one point but unfortunately have lost the email :-( Thanks, Nick

By coincidence somebody else asked about this in IRC this afternoon and I implemented it, so this should supported in svn now. Tom OK, sounds good, thanks for that! Nick ___ Mapnik-users mailing list Mapnik-users@lists.berlios.de

[Mapnik-users] Google Mercator Projection (was: cycle map)

2009-02-12 Thread Nick Whitelegg
Have now got the right projection string working, thanks. However one thing I'd like to clarify in my mind (and apologies if this is slightly OT) is what the Google Mercator projection units, as obtained by the code below, actually represent. They do *not* appear to correspond to pixels at any

[Mapnik-users] Potential uses for the Mapnik plugin?

2010-02-20 Thread Nick Whitelegg
Hi, I originally developed the Mapnik OSM plugin about two years ago, though owing to other commitments I haven't taken things a lot further. However I have a couple of ideas for software using it and was wondering if there was more general interest. Firstly, I'm having quite significant

Hi Dane, Hi Nick! However I have a couple of ideas for software using it and was wondering if there was more general interest. Firstly, I'm having quite significant memory issues attempting to run and maintain a PostGIS database containing OSM data for the UK on my Freemap server.

(Mapnik for php) Am not able to advise on PHP API design other than looking at the APIs of existing PHP modules, but as I develop in PHP myself, this sounds like a great project! Nick ___ Mapnik-users mailing list Mapnik-users@lists.berlios.de

[Mapnik-users] Viability of huge shapefile of LandForm Panorama contours in Mapnik?

2011-03-06 Thread Nick Whitelegg
Hi, Sometime, perhaps over Easter, I'd like to do something I've been meaning to do for a while, and that is create pseudo-Landranger maps by combining OS Vector Map District, contours from OS Landform Panorama, and OSM footpaths. However, to do this I need to transform the contour data from

However, to do this I need to transform the contour data from DXF into something more usable, e.g. shapefile. Apparently gdal can now do this. What I'm a little concerned about, though, is the viability of creating one huge shapefile containing all the contours for the UK, which would be

[Mapnik-users] Issue with low-quality PNG output on Ubuntu 10.10 (mapnik 0.7.1)

2011-10-16 Thread Nick Whitelegg
Hi, I *think* this happened when I upgraded Ubuntu from 10.04 to 10.10 back in March, and I *think* previously I was using a version of mapnik compiled from source whereas now I use the standard ubuntu package.  I know that was a long time ago - but I'm only now getting back to this project.
