I’m new to geo tools I’m trying to add shape file to mapcontext object so I use the following code I found on the quick start guide File file = JFileDataStoreChooser.showOpenFile("shp", null); if (file == null) { return; } FileDataStore store; FeatureSource featureSource = null; try { store = FileDataStoreFinder.getDataStore(file); featureSource = store.getFeatureSource(); MapContext map = new DefaultMapContext(); map.setTitle("Rammallah Parcels"); map.addLayer(featureSource, null); My question is this the best way to add a big shape file to map as I have really big shapefiles more than 50 mb or there any other optimization I could do? Is there any example could I follow to solve this problem? Thanks Feras
