By Michael Purvis, Jeffrey Sambells, Cameron Turner

Until lately, construction interactive web-based mapping functions has been a bulky affair. This replaced while Google published its strong Maps API. Beginning Google Maps purposes with Hypertext Preprocessor and Ajax was once written that can assist you reap the benefits of this expertise on your personal endeavorswhether you’re an fanatic taking part in for enjoyable or a certified development for revenue. This ebook covers model 2 of the API, together with Google’s new Geocoding service.

Authors Jeffrey Sambells, Cameron Turner, and Michael Purvis get rolling with examples that require infrequently any code in any respect, yet you’ll speedy turn into familiar with many aspects of the Maps API. They display robust equipment for concurrently plotting huge info units, developing your individual map overlays, and harvesting and geocoding units of addresses. You’ll see how one can organize substitute tile units and the place to entry imagery to exploit for them. The authors even assist you to construct your personal geocoder from scratch, for these high-volume batch jobs.

As good as offering hands-on examples of actual mapping initiatives, this ebook offers an entire reference for the Maps API, besides the suitable elements of JavaScript, CSS, personal home page, and SQL. stopover at the authors' web site for extra information and advice.

Plot your favorite restaurants? Mark where you parked the car? Show the locations of your business? Maybe mark your band’s upcoming gigs? The possibilities are endless, but it’s really just the beginning. In the next chapter, you’ll be expanding on what you learned here by creating your map data dynamically and learning the key to building a real community: accepting user-submitted information. After that, the weird and wonderful science of geocoding—turning street addresses into latitudes and longitudes— will follow, along with a variety of tips and tricks you can use to add flavor to your web applications.

Most likely, for your application you’ll want more than one marker on the map. qxd 7/25/06 1:26 PM Page 27 CHAPTER 2 ■ GETTING STARTED Then you can cycle through the array, accessing the members of each object and plotting a marker for each entity. When the nesting is combined into one step (Figure 2-5), it becomes a surprisingly elegant data structure, as in Listing 2-7. Listing 2-7. 035307, 'name': 'Washington Monument' } ]; Figure 2-5. A series of objects stored inside an array As you’ll see in the next section, JavaScript provides some terrific methods for working with data in this type of format.

Part 1 goes through Chapter 4 and deals with the basics that a hobbyist would need to get started. You’ll make a map, add some custom pins, and geocode a set of data using freely available services. Part 2 (Chapters 5 through 8) gets into more map development topics, like building a usable interface, dealing with extremely large groups of points, and finding sources of raw information you may need to make your professional map ideas a reality. Part 3 (Chapters 9 through 11) dives into advanced topics: building custom map overlays such as your own info window and tooltip, creating your own map tiles and projections, using the spherical equations necessary to calculate surface areas on the earth, and building your own geocoder from scratch.
