A lightweight Python package for extracting data from Esri REST API endpoints.

Features

• Multiple export formats: Export to GeoJSON, Shapefile, CSV, and GeoDataFrame.
• Robust extraction: Automatically handles Esri's pagination.
• Filtering: Filter data by bounding box or attribute query.
• Bulk exports: Download all layers from a MapServer or FeatureServer.
• Simple CLI: An easy-to-use command-line interface for all features.

Installation

pip install ezesri

Usage

Python library

You can use ezesri as a library to integrate with your Python scripts.

import ezesri

# URL for a public Esri feature layer
url = "your_esri_layer_url_here"

# Get layer metadata
metadata = ezesri.get_metadata(url)
print(metadata)

# Extract layer to a GeoDataFrame
gdf = ezesri.extract_layer(url)
print(gdf.head())

Command-line interface

ezesri also provides a command-line tool for quick data extraction.

Fetch metadata

ezesri metadata <YOUR_ESRI_LAYER_URL>

Fetch layer data

You can fetch a layer and save it to a file in various formats.

• GeoJSON

  ezesri fetch <YOUR_ESRI_LAYER_URL> --format geojson --out output.geojson
  

• Shapefile

  ezesri fetch <YOUR_ESRI_LAYER_URL> --format shapefile --out output.shp
  

• CSV (geometry is dropped)

  ezesri fetch <YOUR_ESRI_LAYER_URL> --format csv --out output.csv
  

You can also filter by a bounding box (in WGS84 coordinates):

ezesri fetch <URL> --bbox <xmin,ymin,xmax,ymax> --format geojson --out <FILE>

Bulk-fetch all layers from a service

You can discover and export all layers from a MapServer or FeatureServer to a specified directory.

ezesri bulk-fetch <YOUR_ESRI_SERVICE_URL> <YOUR_OUTPUT_DIRECTORY>
