Mapnik is an open source toolkit for developing mapping applications. At the core is a C++ shared library providing algorithms and patterns for spatial data access and visualization.

Mapnik is basically a collection of geographic objects like maps, layers, datasources, features, and geometries. The library doesn't rely on any OS specific "windowing systems" and it can be deployed to any server environment. It is intended to play fair in a multi-threaded environment and is aimed primarily, but not exclusively, at web-based development.

For further information see http://mapnik.org and also our wiki documentation.

Create Blog Post for Mapnik 3.0.0 Release

Make an official blog post for Mapnik 3.0.0 Release

Downloads

Hi all,

Since the new site redesign, the downloads section (http://mapnik.org/download/) does not exist anymore. Is there a location where Mapnik Windows binaries can be found?

Thanks!

API links

• Node: http://mapnik.org/node-mapnik/documentation/
• Python: can we update http://mapnik.org/docs/v2.2.0/api/python/index.html ?
• C++: none

Add "Beer" button

As above.

Clarify Post Release Process

mapnik/mapnik#2935 should probably be blogged or written as news

/cc @springmeyer

mapnik.org - broken after github upgrade to Jekyll 3

/cc @springmeyer @amyleew

Code examples

• https://gist.github.com/tmcw/ae916f722b57fb304a29

So we have

• Python
• Node
• C++

/cc @flippmoke for the c++ example, plz gist here and @amyleew will integrate into the site

Mobile browsers

New design works well overall on mobile but we need to adjust margins a little bit ^

Add link on splash to author

like on news pages

/cc @flippmoke

Mapnik configuration XML diagram

@springmeyer @flippmoke @artemp - First stab at diagram for Mapnik configuration XML

Thoughts? Anything missing? Does Include container need to be added? Does data vs. datasource work? Should map image be more specific to .png / .pdf format map image?

Safari IOS

Weird artifacts on mobile (iphone 6 iOS 9.0.2)

Resize mapdesign.png

http://mapnik.org/images/mapdesign.png is 3.5MB - this burns bad mostly because the super slow Milwaukee wifi I'm using is slow, but that's still quite a large image that could probably be smaller jpeg'ed.

Redesign Ideas

Mapnik has grown and flourished as the creative, open mapping community has evolved. Reading Adrian Holovaty's EveryBlock post reminds me of how much time has passed since mapnik.org was originally designed.

We should coordinate an update to mapnik.org's design to reflect the momentum, creativity, and latest visualization features of the project.

Goals

• Help raise profile of the project by sharing who's using Mapnik and how
• Convey the community driven aspect - developer and user contributions from around the world
• Blog - show vibrancy of development, tackling hard problems and having fun pushing limits of rendering
• Fast access to latest info on project: release, both stable and development, packages, downloads

Ideas

• Keep things simple, and easy to update or solid to stay
• Clean full width-layout with healthy whitepace, only horizontal divisions, few vertical divisions
• Unified blue color, since that is a design precident
• Use visual map graphics from a variety of different sources (see below)

Map graphics

Quick brainstorm of possible sources:

• http://cartodb.com/ | http://vizzuality.com
• http://maps.stamen.com/
• http://mapy.cz
• http://kosmosnimki.ru/
• http://openstreetmap.org
• http://mapquest.com
• http://tomtom.com/livetraffic/
• http://developers.cloudmade.com/projects/tiles/documents
• http://mapbox.com/maps/ | https://tilemill.com
• http://koordinates.com/
• http://www.toposm.com/us/index.html
• http://latlon.org/
• https://www.google.com/search?hl=en&tok=-1NGcHedYChxaDo3YM8NRw&cp=4&gs_id=d&xhr=t&q=mapnik&bav=on.2,or.r_gc.r_pw.r_qf.&biw=1081&bih=719&um=1&ie=UTF-8&tbm=isch&source=og&sa=N&tab=wi&ei=6I0dUImIAa35igKwgoGgBQ

Please provide more links to potential graphics in issue comments!

Styling documentation via mapnik-reference

We should pull in https://github.com/mapnik/mapnik-reference and use it to auto-generate awesome pages with all the details Mapnik cartographers need for understanding:

• what styling properties exist
• what they are named in Mapnik (and CartoCSS)
• how they behave
• their stability (e.g. stable or deprecated)
• all this browseable by mapnik version.

This will be similar to the built-in styling docs some people may know from tilemill/mapbox-studio, except that:

• Each mapnik version will be listed
• The community will be able to update and help refine the docs by contributing to mapnik-reference
• Everything will be easily linkable via name anchors. And a link to the place to edit mapnik-reference on github should be provided so it is really really easy for others to provide pull requests with doc improvements.

Once this is done, we should remove the wiki pages that have become unmaintainable, hard to read, and out of date like https://github.com/mapnik/mapnik/wiki/TextSymbolizer.

Update downloads page for Mapnik 3.0.0

Put the new source distribution files for Mapnik 3.0.0 under the downloads section on mapnik.org

Update Python API docs

Once Mapnik 3.0.0 is released we should:

• at least update the docs as per #11 (comment)
• or scope better methods

/cc @flippmoke who I'm sure has been thinking about this. Also /cc @danpat who mentioned he'd be interested in tackling this.

Redesign

@amyleew is grabbing this, I'm helping out with copy and API so that it can land sooner rather than later.

• Front page copy first draft
• First API documentation first draft
• http://mapnik.org/news/ integration
• http://mapnik.org/faq/
• http://mapnik.org/licence/
• Front page copy final draft

Blog topics

Possibilities:

• How to craft the ideal standalone rendering testcase using the CSV plugin
• How to turn of warnings and other logging using the Mapnik 2.1 logging framework
• An intro to mapnik-reference - what it is, how it works, potential uses
• Benchmarks of wkb/wkt parsing

Recessive text ?

@amyleew

The above is too recessive at least on my retina display.

stacks built with mapnik
OpenStreetMap | Mapbox | CartoDB | Stamen | MapQuest | Kosmtik

This is stuff we want people to notice ! :)
/cc @springmeyer @flippmoke

Bulleted lists not formatting properly

Not with:

• format1
• format2

Nor with:

• one
• two

or:

1. this
2. that

/cc @flippmoke @springmeyer

Announce Mapnik 3.0.1

Title column to narrow

cartographers is being split onto two lines.

Example XML on index page

I was trying to use the sample code on the homepage and kept getting this error:

Error: Could not create datasource. Required parameter 'type' is missing  encountered during parsing of layer 'world' in Layer of './style.xml'

I fixed it by adding this line to the XML file:

            <Parameter name="type">shape</Parameter>

This and adding a link to download the shape files would help people get started without having to debug.

Add Amy Lee to authors.yml

For redesign post @flippmoke @springmeyer

Contact / mailing list

Noticing we lost the contact page. I think all it had on it was a link to the google group mailing list. So we need to find a place for this link to live: https://groups.google.com/forum/#!forum/mapnik

Update text

Text on core algorithms | data access | geometry operations sections needs updated (currently old un-related text)
