shapefile-rs

Rust library to read & write shapefiles .dbf files supported via the dbase crate

let mut reader = shapefile::Reader::from_path(filename).unwrap();

for result in reader.iter_shapes_and_records() {
    let (shape, record) = result.unwrap();
    println ! ("Shape: {}, records: ", shape);
    for (name, value) in record {
        println ! ("\t{}: {:?}, ", name, value);
    }
    println ! ();
}

Read & Write Shapefile in Rust

A shapefile is in reality a collection of 3 mandatory files:

• .shp (feature geometry aka shapes)
• .shx (index of feature geometry)
• .dbf (attribute information, aka records)

As different shapefiles can store different type of shapes (but one shapefile can only store the same type of shapes) This library provide two ways of reading the shapes:

1. Reading as Shape and then do a match to handle the different shapes
2. Reading directly as concrete shapes (ie Polyline, PolylineZ, Point, etc) this of course only works if the file actually contains shapes that matches the requested type

Shapefiles shapes

The Point, PointM and PointZ are the base data types of shapefiles, the other shapes (Polyline, Multipoint, ...) are collections of these type of points with different semantics (multiple parts or no, closed parts or no, ...)

With the exception of the Multipatch shape, each shape as a variant for each type of point. (Multipatch always uses PointZ) Eg: For the polyline, there is Polyline, PolylineM, PolylineZ

Writing

To write a file see the writer module

Features

The geo-types feature can be enabled to have access to From and TryFrom implementations allowing to convert (or try to) back and forth between shapefile's type and the one in geo_types
