Examples
Reading a shapefile
// open a shapefile for reading
shape, err := shp.Open("points.shp")
if err != nil { log.Fatal(err) }
defer shape.Close()
// fields from the attribute table (DBF)
fields := shape.Fields()
// loop through all features in the shapefile
for shape.Next() {
n, p := shape.Shape()
// print feature
fmt.Println(reflect.TypeOf(p).Elem(), p.BBox())
// print attributes
for k, f := range fields {
val := shape.ReadAttribute(n, k)
fmt.Printf("\t%v: %v\n", f, val)
}
fmt.Println()
}
