ArcGIS JavaScript API v1.3 OUT

This is a developer centric release. The enhancements include custom layers, error handling and more layer management in the Map which have been requested time & time again. Check out the full list of What's New.

At the Dev Summit in March, Jeremy & I will be presenting the 'An overview of the ArcGIS JavaScript APIs' and 'Developing Advanced Applications with the ArcGIS JavaScript API' sessions. Jeremy will also be presenting 'Patterns and Best Practices for Building Applications with ArcGIS API for JavaScript' and finally 'Using the ArcGIS Server REST API' with Keyur. To see when these sessions are offered, go to the session search page and search by session name.

We will take an in-depth look into the v1.3 developer features in the advanced sessions. In depth looks into error handling, using esri.request, custom layer, etc. You can hear a podcast about our sessions too.

Google Latitude & the iPhone

I'm sure everyone has heard about Google Latitude, essentially a mobile app that lets you share and find friends in the vicinity, with caveats. Well, what it may potentially tell us about the next iPhone OS release is that the OS will probably have background processes. I know its a long shot, but here goes:

The google latitude page states: http://google.com/latitude -> Will it work with my phone? -> iPhone and iPod touch devices (coming soon).

In the FAQ for Latitude: http://www.google.com/support/mobile/bin/answer.py?answer=136647&topic=20071, the page states:

... Latitude can automatically detect and update your location in the background ...

... you will have the option to continue sharing your location in the background even with Maps for mobile closed.

So in order for Latitude to truly work on the iPhone, they need background process support in the SDK. And guess what, it may be 'coming soon'. Fingers crossed & hoping so...

Integrating SVG in blogger post

This is in response to a comment to my earlier post Integrating Dojo in blogger post.

If you want to just use SVG, the following sample works. It uses 2 external JavaScript files, one for basic SVG context and drawing (also used in the Simple SVG Shapes post) and the 2nd one for actually drawing the content.

Here is the HTML markup:

<div id="surface" style="width:300px; height:300px; border:1px solid #000;"></div>
<script type="text/javascript" src="http://ecodevil.net/dev/blog/svg.js"></script>
<script type="text/javascript" src="http://ecodevil.net/dev/blog/blogger_svg.js"></script>

I also tried with Dojo GFX. GFX is a nice abstraction layer to SVG/VML graphics. I tried integrating it into the blogger page, but that didn't worry, it kept throwing a console not found error. Here's the external JavaScript file incase you would like to try it.

ArcGIS JavaScript API v1.2 OUT

We've worked on this for the last 3-4 months or so. Its a major release for us with a LOT of new features & updates.

We have tried to keep the backward compatibility and we pretty much have it. Just a few minor things which are stricter, for example, setting an Extent in the Map constructor should have a SpatialReference and the SR and extent values should be in sync.

Integrating Dojo in blogger post

So I have been working on integrating Dojo within my blog... so here goes.

Open lightbox

So first, I should thank this blog post on integrating an external JavaScript module within a blogger post. So essentially all the work is done in an external file. But this document still contains the markup that the dojo parser parses to render the light box.

Click on the 'Open lightbox' link below and it will open up a dojo lightbox. These are photos of a sunset I took while in Vancouver in August. Use the keyboard cursor keys to navigate through the photos.

<div class="tundra">

<a href="..." dojoType="dojox.image.Lightbox" group="sunset" title="A beautiful sunset">Open lightbox</a>
<a href="..." dojoType="dojox.image.Lightbox" group="sunset" title="The colors where AMAZING"></a>
<a href="..." dojoType="dojox.image.Lightbox" group="sunset" title="Taken from my friend's apartment"></a>
<script type="text/javascript" src="http://ecodevil.net/dev/blog/blogger_lightbox.js"></script>

</div>

Thats it.

The Mobile Web

So recently the guys in the ArcGIS Mobile team (Fred, Jeff & Myles) asked me whether I could put together a blog posting about integrating the JSAPI to work in mobile browsers. So here's a first of several blog posts on The Mobile Web. If you're interested in the bringing your ArcGIS Server content to mobile devices, watch the the ArcGIS Mobile Blog.

This particular post simply shows how to make REST calls and doesn't have any JSAPI, but this one will work on any mobile browser, even IE Mobile.

You can find the page hosted here. So whip out that mobile phone of yours and go to http://ecodevil.net/dev/blog/basicMap.php and check it out. Click the +/- to zoom in/out and the N/E/S/W to pan in the specific direction.

DDD & AjaxExperiece

A couple of weeks ago the Dojo guys gave me the opportunity to present the ArcGIS JavaScript API at the Dojo Developer Day and Ajax Experience. Here's a wrap up on the proceedings from both at Uxebu's blog and Sitepen's blog. Btw, I'm in the right corner in the red shirt in the group photo. I wore my Dojo shirt the previous day and didn't wear it that morning.
