createTableFromShp

public static String createTableFromShp(ASpatialDb db,
                                        File shapeFile,
                                        String newTableName,

                                        boolean avoidSpatialIndex)
                                 throws Exception

Create a spatial table using a shapefile as schema.

Parameters:

db - the database to use.

shapeFile - the shapefile to use.

newTableName - the new name of the table. If null, the shp name is used.

forceSrid - an optional srid to force the table to.

avoidSpatialIndex - if true, no spatial index will be created. This is useful if many records have to be inserted and the index will be created later manually.

Returns:

the name of the created table.

Throws:

Exception
