FlatGeobuf for Rust

Rust implementation of FlatGeobuf.

FlatGeobuf is a performant binary encoding for geographic data based on flatbuffers that can hold a collection of Simple Features including circular interpolations as defined by SQL-MM Part 3.

Usage

use flatgeobuf::*;

let mut filein = BufReader::new(File::open("countries.fgb")?);
let mut fgb = FgbReader::open(&mut filein)?;
fgb.select_bbox(8.8, 47.2, 9.5, 55.3)?;
while let Some(feature) = fgb.next()? {
    let props = feature.properties()?;
    println!("{}", props["name"]);
}

With async HTTP client:

use flatgeobuf::*;

let mut fgb = HttpFgbReader::open("https://pkg.sourcepole.ch/countries.fgb").await?;

fgb.select_bbox(8.8, 47.2, 9.5, 55.3).await?;
while let Some(feature) = fgb.next().await? {
    let props = feature.properties()?;
    println!("{}", props["name"]);
}
