Leaflet.js Essentials: Create interactive, mobile-friendly mapping applications using the incredibly light yet powerful Leaflet.js platform.

About This Book

• Create and customize your maps and mapping applications using JavaScript and Leaflet.js
• Leverage the features of existing libraries, plugins, and HTML 5 geolocation APIs to enrich your mapping applications
• Learn the advanced features of Leaflet.js in a streamlined, step-by-step manner

Who This Book Is For

If you are a web developer working with geospatial concepts and mapping APIs, and you want to learn Leaflet to create mapping solutions, this book is for you. You need to have a basic knowledge of working with JavaScript and performing web application development.

What You Will Learn

• Incorporate Tile Layers and Web Mapping Services into your map
• Write custom functions that use events to make interactive maps
• Add GeoJSON data to a web map
• Create your own images to use as markers on your map
• Build desktop applications using C#
• Make heatmaps and chloropleth maps
• Take advantage of third-party plugins to enhance your map

In Detail

Starting with how to create maps, you will learn about choosing your basemap and customizing it by adding various attributes such as zoom, start view, pop ups, and so on.

Once you have gained experience of creating your own map with Leaflet, you will move on to combining Leaflet with GeoJSON and adding geometry objects and features to your maps.

Moving ahead, you will proceed to create custom markers using images and discover various plugins such as the Cluster Marker plugin, the Bouncing Marker, and the Animated Marker to animate and move markers. You will then explore the latest ESRI features available on Leaflet and make use of its updated JavaScript library.

Finally, you will understand how Leaflet enables you to use Node.js, C#, and Python alongside its own library to efficiently create maps.

Paul Crickard III

Paul Crickard III has been programming for over 15 years and has focused on GIS and geospatial programming for 7 years. He spent 3 years working as a planner at an architecture firm, where he combined GIS with Building Information Modeling (BIM) and CAD, and built web-based GIS applications to display and modify architectural data. He has given presentations to the New Mexico Public School Facilities Authority on BIM and GIS integration and on the use of GIS for Facility Planning, and the BIM505 Users Group on GIS as an interactive frontend to BIM and editing BIM data via web applications. Currently, Paul works as a programmer analyst in Albuquerque, specializing in the design, maintenance, and the implementation of geospatial applications. He has written plugins and extensions for ArcMap and ArcGIS Explorer Desktop to utilize NoSQL databases and send data using the Advanced Message Queuing Protocol (AMQP). Paul has built applications using OpenLayers and Leaflet.js and is currently utilizing the ESRI JavaScript API in production. Paul tries to incorporate Python in geospatial development wherever possible. From building plugins, toolboxes, and the Field Calculator functions in ArcMap to coding standalone desktop and web applications, pyshp is his favorite library for geospatial Python applications. When he is not coding, Paul enjoys relaxing with his wife and son, cooking, and brewing beer.
