Chapter 6. Mapping Geographical and Spatial Data

In this chapter we will cover:

  • Showing a map using the openscales.org API
  • Adding points of interest to a map
  • Parsing data to use as region fill
  • Coloring a map
  • Adding multiple layers to a map
  • Overlaying a heat map

Introduction

This chapter will show how to bring data and maps together to derive further meaning. We will start with simple recipes just showing a map and points of interest, and end up generating heat maps. All the maps will use the OpenScales API, sometimes in a dynamic manner where you can move and explore the map, and sometimes in a more static way to show just one area.
