Node-Mapnik

Mapnik is a C++ toolkit for developing map-centric applications.

Mapnik is also one of the tools used to create the famous OpenStreetMap (OSM) mapping project.

On the other hand, Node-Mapnik is a JavaScript client for this toolkit, allowing Node.js developers to create mapping applications that inter-connect with a local or remote Mapnik installation and access one or more of its mapping features and tools.

This library comes with tests and examples.

What is new in this release:

• Ugraded to Mapnik 3.x version with totally new geometry storage
• Upgrade to mapnik-vector-tile@0.8.0
• Upgraded to node-pre-gyp@0.6.5
• Added an additional parameter to Projection initialization. This prevents the initialization of a proj4 object internally. This will only be useful when reprojecting from epsg:4326 to epsg:3857 and vise versa.

What is new in version 3.3.1:

• Ugraded to Mapnik 3.x version with totally new geometry storage
• Upgrade to mapnik-vector-tile@0.8.0
• Upgraded to node-pre-gyp@0.6.5
• Added an additional parameter to Projection initialization. This prevents the initialization of a proj4 object internally. This will only be useful when reprojecting from epsg:4326 to epsg:3857 and vise versa.

What is new in version 3.3.0:

• Ugraded to Mapnik 3.x version with totally new geometry storage

What is new in version 1.4.14:

• Avoid startup error if $HOME environment is not known
• Fixed all tests on windows

What is new in version 1.4.5:

• Updated to use Mapnik 2.3.x SDK with rapidxml parsing fix.

What is new in version 1.4.4:

• Subtle VectorTile.composite bugs fixed to handle both tiles created from setData and those just rendered to.
• VectorTile.fromGeoJSON method changed to VectorTile.addGeoJSON.
• Removed initializing and cleaning up global libxml2 structures because XML2 is no longer the default in node-mapnik binaries.

What is new in version 1.4.0:
