7.1. GeoTools Feature Types¶
A SimpleFeatureType defines a GeoTools schema, and consists of an array of well-known attributes. GeoMesa
supports all of the standard GeoTools attribute types, as well as some additional ones. When creating
a SimpleFeatureType for use in GeoMesa, be sure to use the provided classes, instead of the standard
GeoTools DataUtilities:
import org.locationtech.geomesa.utils.interop.SimpleFeatureTypes;
SimpleFeatureTypes.createType("example", "name:String,dtg:Date,*geom:Point:srid=4326");
import org.locationtech.geomesa.utils.geotools.SimpleFeatureTypes
SimpleFeatureTypes.createType("example", "name:String,dtg:Date,*geom:Point:srid=4326")
