Geographic Information System (GIS) data can come in a lot of forms, which can lead to confusion in how to represent data. One popular solution is GeoJSON, a data standard that was created by the Internet Engineering Task Force and defines a way to organize GIS data in the JSON format natively supported by the majority of web development languages, libraries, and frameworks. In this article we’ll look at the GeoJSON format, then use a GeoJSON data set to draw regional borders on a map with TomTom JavaScript Maps SDK for Web.

The TomTom Maps SDK for Web offers the easiest way to access the TomTom APIs for displaying maps along with other data sources. In this article, we'll build a map that displays the population density of the USA in the form of a heatmap. You'll see that it's remarkably easy to grab an external data source and use it to display custom layers on a map.

Government agencies and NGOs gather data about their communities that provides insights and information valuable for effective programs and planning. We’ll examine five innovative ways governments and agencies are collecting or using open data sources to improve civic life. For each of these five topics, we’ll look at the opportunities for developers to create applications and the TomTom APIs and SDKs they can use to power these applications.

This Halloween, you can create an application that uses data, but doesn’t abuse it, and have fun experimenting with location-based code for a good cause. Let's explore the ethics and use case of using someone else’s location info, and how the Geofencing API can still offer engineers a way to create applications that protect the privacy of all parties.
