Sean Gillies on OGC WMTS

Sean is all over OGC’s Web Map Tiling Standard.

I have sent in a “public comment” advising the authors on how to better follow the REST style. To be honest, I’d rather the OGC stayed away from REST, but if it won’t, I’ll insist it’s done properly and doesn’t misinform mainstream GIS developers. I’ll even try to help as much as the OGC’s closed process will allow.

We talk about open standards quite a bit and when it comes to GIS software implementing them, OGC is usually what we see. It would be a shame to see WMTS fail as much as WFS has in the marketplace because it is ill conceived. Hopefully the OGC will take advantage of Sean’s comments to improve the spec. The OGC comment process has to be better than this:

No, now go away or I shall taunt you a second time.

Microsoft Releases Virtual Earth Silverlight Map Control

So Microsoft has released a Silverlight map control to developers:

Now, because we’re using Silverlight, .NET developers (all 6 million + of you) can leverage your skill set to build rich, killer apps that make your data bling and highlight media in a geo-contextual way as has never been seen before. VESL leverages all of the drawing tools that come with Silverlight, so for Silverlight developers you’re not relearning how to take your computer art and force it onto a map. Instead, you’re starting with a map-based canvas instead of a blank one.

Looks simple enough to leverage and I’m guessing since Microsoft developers are in love with Silverlight, it won’t be long before the JSAPI is pushed aside. It looks like people will start having to pick a side, Flash or Silverlight.

Silverlight is sexy

The 2009 ESRI Developer Summit (and the 2009 Business Partner Conference) is upon us

I’ll be heading out from Tempe on Saturday for the annual ESRI Business Partner Conference and the ESRI Developer Summit. As many of you already know, I’ll be presenting a talk on using the ArcGIS Server REST API with OpenLayers.

Using OpenLayers with ArcGIS Server REST API

Should be a good time getting everyone who is working with OpenLayers and ArcGIS Server or those who want to start working with it. OpenLayers support for ArcGIS is messy, but the pieces are coming together quickly so is a great time to get involved. And I’m not the only talk that covers using ArcGIS with Open Source tools. It isn’t about closed development environments anymore, it is about using the best tools to get the job done.

As I said above, I’ll be there all week so if you’d like to talk over an adult beverage GIS at either the Business Partner Conference or the Developer Summit, email me ( or call me on my mobile phone (602-819-2142).

Oh and don’t forget to RSVP for the DTSAgile DevSummit Party!

JSMag, the magazine for JavaScript developers

OK, so maybe you aren’t a Microsoft MVP for .NET or maybe you think Java is an island of Indonesia (we are all Geographers of course) . But darn it, you know how to work with the Google Maps API or you dream about jQuery. Does that mean you don’t get a “professional” magazine of your own? Well wonder no longer, say hello to JSMag. Their mission?

“JSMag aims to brings you quality JavaScript content to educate, movitate [sic] and inspire you in your work with JavaScript.”

Mark Twain used to end up every day on his porch reading JSMag and enjoying a stogie.

ESRI ArcGIS Server Mashup and ArcGIS Mobile Code Challenges Voting Updated


UPDATE: OK, it has come to my attention that these links actually don’t do a thing. ESRI requires you to use the email that was sent to you. Yea, you’d assume they’d track this better than some URL, but alas no. So if you voted by clicking on the links above, you’ll have to **VOTE AGAIN** using the email you received from ESRI. If you didn’t get an email, ESRI doesn’t let you vote. Have to pull the siren out for this one folks.**

The voting is open for ESRI’s 2009 ArcGIS Server Mashup and ArcGIS Mobile code challenges.

Vote for ArcGIS Server Mashup Code Challenge
First prize – $7,000
