Calculating Distances and Areas in Google Maps API 3

As I mentioned in the article Extending Google Maps API 3 with libraries a couple of weeks ago, you can add functionality to the Google Maps API by using libraries. One of these libraries are the Geometry Library. In this article I will show how you can use the function of that library to calculate distances and areas. I will also explain some additional navigation functions that you might find useful.

Action-Confirm Design Pattern

Inspired by the User Interfaces of mobile apps on the iOS and Android platforms, I created a delete button using a design pattern that I’ve named the Action-Confirm design pattern. I created this for a web application that I recently worked on.

In a nutshell it’s an Action button that transforms into a Confirm button when clicked. It’s a compact solution that provides the user with a way to confirm a possibly destructive action without interrupting the flow of the application.

Extending Google Maps API 3 with libraries

Google Maps API 3 is streamlined to include just the core functionality needed to create basic maps. It’s architected that way too ensure that the API will load as fast as possible. It’s unnecessary for the browser to download and parse functionality that’s not needed. If, however, you need to use specific functionality such as being able to measure distances or display ads, you can get this additional functionality by including a library in the API.

This article will describe how to do just that and what libraries that are currently available.

Dancing markers

The Google Maps API team recently added an eye catching new feature to the Google Maps API v3 which makes it possible to animate markers. This feature has been available in v2 for quite some time and occurs when you drag and drop a marker. It rises the marker up when you drag it and then bounces it into position when you drop it.

The API team however, wasn’t satisfied with just adding what was available in v2. They also added a drop animation similar to the one found in Google Maps on the iPhone. It looks like the marker is being dropped into place from above and then ends with a small bounce.

But they didn’t stop there either. They also added the ability to animate the markers at will. So now we can trigger the animation whenever we feel like it using the setAnimation() method of the Marker object.

A lot of the web browsing these days takes place on mobile devices. Therefore it’s important to know how to design web pages and maps for these.

There are however some things to consider. In this article I will explain what these things are and how it’s done.

I’m writing a book about Google Maps

It’s been a while since I last wrote on this blog and I thought I would get you up to speed why that is. The reason is that I’ve been occupied with writing a book about Google Maps.

I haven’t written a book before so this is new territory for me. What I’ve noticed so far is that it progresses far slower than I predicted, but at least it progresses steadily even if slower than anticipated. I’ve taken a few weeks off of my regular work to devote to writing this book but this time won’t suffice, so there will probably be quite a few late nights and weekends of writing as well.

Forms that Work

Forms that Work is a book on how to design web forms properly. Some time ago I reviewed a similar book, Web Form Design by Luke Wroblewski, which deals with the same subject. I then thought that this was a very narrow scope for a book, but perhaps it was not since this book was published shortly after.

No doubt web forms are all around us, so the need for knowledge and skill to design them well should be great. I certainly can’t seem to get enough of these books. Continue reading
