[OSM-talk] mapbook: a PDF map book creator
I'd like to announce the release of version 0.01 of mapbook, a PDF map book creator for mapnik generated maps. This is very much a development release and is missing what I view to be important features. mapbook can be found at https://github.com/pnorman/mapbook Features: It uses Mapnik's AGG-based renderer and should take any mapnik .xml file Adjustable resolution and paper size Uninteresting map pages may be skipped and omitted Has not exploded Dependencies Mapnik2 (may work with older versions with minor code tweaks) Python >= 2.6 Cairo, pycairo Pango Pangocairo Notes: The user is responsible for inserting an appropriate copyright page for the map they are using Printing high-DPI maps can be both time and toner intensive Upcoming features: An index page feature for an overview of the area Headings The ability to tweak a specific page to expose the map under the border Cleaner code? A license for the code? A scale bar Known issues: Adjusting --firstpage and --blankfirst is confusing Some stylesheets use images for icons which do not work well at different resolutions (e.g. osm.org mapnik). Using an alternate style which uses svg icons (e.g. mapquest open) is suggested. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
[OSM-talk] THANK YOU!!
a quick thank you to those mappers who have contributed a substantial amount of roman features to the map in the last few weeks. I have now got about 20% of my initial tracing of about 11,000 km of roman roads narrowed down to a comfortable level of accuracy. Many thanks mick ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
[OSM-talk] Creating a subset of OSM and storing it in Postgis tables
I need to build a database of a subset of features from a specific area, storing them in a series of tables according to feature type (eg. natural, historic, waterway, ...) from predefined subsets of the planet file. In doing this I hope to minimise: 1 my impact on OSM's resources 2 amount of data I have to download (I'm in Australia so I'm burdened with 20GB monthly traffic limits). My current thinking is that I need to: 1. download the weekly England, Scotland & Wales excerpts from geofabrik 2. merge the 3 files 3. filter out what I don't need 4. load the rest into the db tables 5. merge in data from other sources 6. manipulate the data as I require So far 1. is fine, I can even do a script for when I need it 2. I have a very clunky answer for - convert to mapinfo tabs, copy 1 file to a new file, then manually copy the contents of the other two to the new file. 3. I can just about make very slow headway with by manually deleting individual redundant objects 4. failure - I can't get my head around the complexity of db design. 5. can do somewhat within the constraints of parts 1 - 4 not being solved. 6. I can manage within the constraints of parts 1 - 4 not being solved. I think my main problem is not being able to apply tools like osmosis and osm2pgsql due to the docs being rather too abstract for me to see the answer, maybe I'm loosing my mental agility. Is there anyone out there who can point me to simplified instructions or has the time and patience to help me with any part of the above. mick ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] Map Co-ordinates for towns, etc in UK
In my experience as a rambler, who enjoys a pint. The church and pub in a village are not far apart, so in an unknown village if you want to find the pub, head for the church.

Re: [OSM-talk] Map Co-ordinates for towns, etc in UK
There is no grid system for UK towns, however where the main post office is or was is a reasonable approach to positioning the town centre. In terms of villages the church is usually the best.

Re: [OSM-talk] Map Co-ordinates for towns, etc in UK
If you refer to old OS maps the location of the place name seems most often to be positioned in relation to certain specific features. Where there is a parish church they seem to use that, where not its often the post office or the village pub, if none of these are present then some central other communal feature of the hamlet for instance. Of course this could just be a be cartographic approach taken by the OS.

Although most of them have vanished, localities are still centered on where the post office was. -- regards Kenneth Gonsalves ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] Map Co-ordinates for towns, etc in UK
The logical centre and the geometrical centre aren't necessarily anywhere near each other --- for example, what is generally thought of as the "city centre" of Cambridge UK is some way west of the crossing point between the lines between the northmost and southmost, and westmost and eastmost, points of the outline of the city. (I tried drawing those lines a few years ago, they crossed in Mill Road Cemetery, which makes it the "dead centre" of the city ;-) ) __John ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
