GeoFetch.jl

Welcome to the documentation for GeoFetch.jl — a unified interface for fetching geospatial data from multiple providers.

Overview

GeoFetch organizes geospatial data access around four core types:

Source → Dataset → Chunk → File

• Source — A data provider (e.g. NOMADS(), CDS(), Landfire()).
  • datasets(source) lists available datasets.
  • help(source) returns a documentation URL.
• Dataset — A configurable remote dataset (e.g. LandfireDataset(product="FBFM40")).
  • chunks(project, dataset) resolves it into downloadable pieces.
• Chunk — A single downloadable file with a URL and metadata.
  • fetch(chunk, filepath) downloads the data to disk.
• Project — Ties everything together: a spatial/temporal region of interest, an output directory, and a list of datasets to fetch.

Quickstart

Create a Project with a geometry and datasets, then fetch it:

using GeoFetch, Dates, Extents

p = Project(
    geometry = Extent(X=(-106.0, -105.0), Y=(39.0, 40.0)),
    datasets = [LandfireDataset(product="FBFM40")],
)

fetch(p)
