Introduction

Welcome to the API documentation. LandSummary is a new service, and only a portion of our API methods are currently available to the general public. Please check back for future updates.

Limitations

The free public API is not intended for large-scale studies. Use of this API without an authorized API Key is limited to 50 queries per day, and a maximum polygon area of 100,000 acres (about 400 square kilometers) for any summary query. Larger buffers and unlimited queries are available by signing up.

Usage

The base URL for all demographic summary queries is: http://landsummary.com/summary/

The following parameters are available:

Output Format

The default response is a JSON dictionary. However, you may also download a spreadsheet version if you wish by adding a format parameter:
http://landsummary.com/summary/?x=-121.5&y=37.6&shape=square&radius=1000&services=nlcd&epsg=4326&format=csv

Projection

The default for all Locations is “EPSG:4326”), but you may provide your Location in all projections that are defined in the standard EPSG reference, as well as a few others (such as using 900913 for “spherical mercator”)
