Google Maps JavaScript API Cookbook

Overview of this book

Day by day, the use of location data is becoming more and more popular, and Google is one of the main game changers in this area. The Google Maps JavaScript API is one of the most functional and robust mapping APIs used among Geo developers. With Google Maps, you can build location-based apps, maps for mobile apps, visualize geospatial data, and customize your own maps.Google Maps JavaScript API Cookbook is a practical, hands-on guide that provides you with a number of clear, step-by-step recipes that will help you to unleash the capabilities of the Google Maps JavaScript API in conjunction with open source or commercial GIS servers and services through a number of practical examples of real world scenarios. This book begins by covering the essentials of including simple maps for Web and mobile, adding vector and raster layers, styling your own base maps, creating your own controls and responding to events, and including your own events.You will learn how to integrate open source or commercial GIS servers and services including ArcGIS Server, GeoServer, CartoDB, Fusion Tables, and Google Maps Engine with the Google Maps JavaScript API. You will also extend the Google Maps JavaScript API to push its capabilities to the limit with additional libraries and services including geometry, AdSense, geocoding, directions, and StreetView.This book covers everything you need to know about creating a web map or GIS applications using the Google Maps JavaScript API on multiple platforms.

Adding animated lines to maps


Polylines are the representations of Earth's features on the Earth, but sometimes, they are not enough to show the mobility of Earth features. For example, a river can be shown with the help of polylines, but the flow direction of the river can't be demonstrated by the polylines alone. Animating polylines can be a solution to show the mobility of Earth features. The flow direction of a river can be shown with the help of animated polylines.

The Google Maps JavaScript API has a symbol feature that can add vector-based images to a polyline in the form of a symbol. You can create your own symbol with the help of the Symbol class, or you can also use the predefined symbols that are accessed from the SymbolPath class.

In this recipe, we will create an animated polyline from the previous recipe. This animation shows that a car is moving from Istanbul to Ankara.

Getting ready

In this recipe, we will use the fourth recipe of this chapter as a template.
