# Shapefile Plugin
|
|
|
|
|
|
|
|
This plugin supports reading shapefiles. They can also be read using the [[OGR]] Plugin, but the *shape* plugin is better tested and more mature.
|
|
|
|
|
|
|
|
The shapefile plugin will run fastest if you build indexes for your shapefiles using the 'shapeindex' command line tool installed when you build Mapnik.
|
|
|
|
|
|
|
|
For other plugins see: [[PluginArchitecture]]

# Styling
|
|
|
|
|
|
|
|
To style a layer, use any of the Symbolizers like Point, Polygon, or Line, depending on the geometry type.

# Usage
|
|
|
|
|
|
|
|
## Python
|
|
|

|
|
|
|
|
|
Plugin datasource initialization example code can be found on PluginArchitecture.
|
|
|
|
|
|
|
|
A Shapefile datasource may be created as follows:
|
|
|
|
|
|
|
|
```cpp
|
|
|
|
{
|
|
|
|
parameters p;
|
|
|
|
p["type"]="shape";
|
|
|
|
p["file"]="path/to/my/shapefile.shp";
|
|
|
|
|
|
|
|
// Bridges
|
|
|
|
Layer lyr("Vector");
|
|
|
|
lyr.set_datasource(datasource_cache::instance()->create(p));
|
|
|
|
lyr.add_style("vector");
|
|
|
|
m.addLayer(lyr);
|
|
|
|
}
|
|
|
|
```
|
|
|
|
|
|
|
|
## XML
|
|

|
|
|
|
|
```xml
|
|
|
|
<Layer name="vector" srs="+init=epsg:4236">
|
|
|
|
<StyleName>polygon</StyleName>
|
|
|
|
<Datasource>
|
|
|
|
<Parameter name="type">shape</Parameter>
|
|
|
|
<!-- you can also point to your shapefile without the 'shp' extention -->
|
|
|
|
<Parameter name="file">/path/to/your/shapefile.shp</Parameter>
|
|
|
|
</Datasource>
|
|
|
