Download GIS Web Services — ArcGIS, OGC API & WFS

Download queryable features from a public ArcGIS FeatureServer/MapServer, OGC API Features collection or WFS 2.0 service.

Input & limits

A public service URL that permits browser CORS requests and GeoJSON output. Authentication and raster map images are not supported.

What you download

Received features as WGS 84 GeoJSON/CSV plus a query report stating source, filters, retrieval time and whether the export is partial.

How to use

  1. Paste a service URL or try a public example. Read its layers and fields.
  2. Choose a queryable layer, properties, optional supported filter and bounding box. Preview the first ten records.
  3. Fetch the feature pages, check the completeness status, then download or send the result to another tool.

Frequently asked questions

Does this bypass a service’s limits or access controls?

No. Requests go directly from your browser to the public provider. CORS, authentication, query capabilities and transfer limits remain in force.

How do I know whether a download is complete?

The result and query report explicitly mark capped or provider-limited downloads as partial. The tool bounds requests to 20,000 features, 50 MB and 100 pages.
