โ” What is the Application Programming Interface (API) Series?

๐Ÿ™Œ At the United States Geological Survey, we’re making high-quality water information discoverable, accessible, and usable for everyone.

Water data should be usable ๐Ÿฆพ! Our modernized APIs provide a way for you to display our water data in the format that works best for you. Learn more about how & why to use USGS modernized APIs to integrate our water data in your applications.

In this API webinar series, we’ll touch on what USGS water data is, then we’ll discuss the API formats that have been used in the past and why the new API formats are better for you.

OGC API - Features Example

โœ Here is an example Leaflet webmap that is making a live call to the USGS Implementation of OGC API - Features, and below it is the minimal code needed to build your own map! We will talk in more detail about the structure of the USGS implementation of OGC API - Features during the seminar.

Here is the same code in a single html view that you can edit in any text editor.
