Have a look at the CSV2Shp tutorial. Shapefile can only hold one kind of
content.
So if you want to convert from Point --> Polygon using buffer ... you will need
to make a second FeatureType (and thus a second FeatureCollection) "the_geom"
attribute of type Polygon.
However if you are just focused on rendering, the PointSymbolizer can apply a
buffer for you (just set the mark size).

Hello everyone,
we are having problems creating a SimpleFeature from a Geometry. These
are our steps:
1. Read a number of features from a Shapefile
File file1 = new File("bla.shp");
FileDataStore store1 = FileDataStoreFinder.getDataStore(file1);
SimpleFeatureSource featureSource1 = store1.getFeatureSource();
SimpleFeatureCollection s1 = featureSource1.getFeatures();
2. Get a specific feature from the collection and buffer
SimpleFeature feature1 = ....
Geometry geom1 = (Geometry) feature1.getDefaultGeometry();
Geometry buffer = geom1.buffer( 0.1 );
3. Converting the buffer-Geometry back to a SimpleFeature for further
processing / visualization
We tried:
feature.setDefaultGeometry(buffer); // ---> Doesn't work
We have also tried using the SimpleFeatureBuilder to create a new
Feature, but it didn't work out:
SimpleFeatureType featureType = feature1.getType();
SimpleFeatureBuilder builder = new SimpleFeatureBuilder(featureType);
builder.add( buffer );
builder.add( "theName" );
SimpleFeature x = builder.buildFeature( "fid908" );
s1.add(x); // --> returns false, so does not work
How the hell do we convert the buffer-Geometry to a Simple Feature? Can
anyone help with simple step by step instructions or an URL?
Kind regards
