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::*;
fn main() {
let mut filein = BufReader::new(File::open("countries.fgb")?);
let mut fgb = FgbReader::open(&mut filein)?.select_all()?;
while let Some(feature) = fgb.next()? {
println!("{}", feature.property::<String>("name").unwrap());
println!("{}", feature.to_json()?);
}
}
With async HTTP client:
use flatgeobuf::*;
async fn process() {
let mut fgb = HttpFgbReader::open("https://flatgeobuf.org/test/data/countries.fgb")
.await?
.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"]);
println!("{}", feature.to_wkt()?);
}
}
