Overview

Felt’s Developer Tools

There are a variety of ways to interact with Felt’s modern GIS platform outside of the user interface. They can be grouped into two buckets: tools for programmatically creating and modifying maps, and tools for building custom experiences for map viewers. These tools can be used to solve distinct challenges and also be used in tandem with one another.

Creating and modifying maps

Felt’s REST API allows editors to interact with the Felt platform via code, performing actions such as creating new maps, adding data to maps, styling layers, and more. The REST API can be leveraged from any environment that is capable of sending GET and POST requests.

For Python users, interactions with the REST API are simplified through the felt-python module, which can be installed with pip and used to call the REST API endpoints directly from Python functions.

Creating custom applications

Felt’s user interface allows a large amount of customization, offering the ability to generate complex cartographic designs, adding components to create a dashboard, and much more.

However, sometimes application developers need further control over the experience of viewing and/or interacting with a map. For example, they may want to run custom logic after a user clicks on a feature in a layer, or animate data on the map based on other types of user input elsewhere on the webpage. For these situations and many more, Felt’s JavaScript SDK allows developers to load a Felt map into their application while providing opportunities to hook into the interaction loop and more broadly customize the experience of the map viewer.
