Webinar: Migrating from Web ADF to RESTful Technology

>> December 20, 2011 10 AM PDT

Given Esri’s deprecation of Web ADF, many organizations are in the process of devising migration strategies to shift to Esri’s RESTful web-based mapping platform. In this 30-minute webinar, we’ll explore strategies and best practices to help ensure smooth, efficient transitions.

If you are planning to migrate Web ADF applications, this is an ideal time to rethink how your web-based mapping applications are designed, developed and maintained in order to gain efficiencies and improve productivity moving forward.

This free Webinar will be of interest to GIS administrators, GIS managers and analysts currently using Web ADF who are involved in planning for the transition to ArcGIS for Server using a RESTful approach.  The presentation will take about 30 Minutes, but please allow for an additional 15 minutes for Q&A.

Webinar: HTML5 and Esri-based Web Mapping

>> February 1, 2012 10 AM PDT

With the steady growth in smart mobile devices and with every modern web browser now supporting HTML5, the adoption of HTML5 for web-based mapping is clearly on the rise.  This 30-minute webinar will provide an overview of HTML5 for generalists, theorize on likely timelines around adoption, and provide information to help you ensure that your organization is positioned to embrace this important standard at the right time.

It may still be a year or more before browser support for the HTML5 standard enables wide-spread adoption, and until then, a pragmatic approach works best. But don’t let that hold you back! Even today, HTML5 offers the opportunity for building platform agnostic mobile applications and solving real-world problems and we will show some examples using the forthcoming Geocortex Viewer for HTML5.

 This free Webinar will be of interest to GIS administrators, GIS managers and analysts currently using Esri’s ArcGIS Server platform. The presentation will take about 30 Minutes, but please allow for an additional 15 minutes for Q&A.

Migrating from Esri ArcIMS to ArcGIS for Server

A frequent discussion topic between Latitude Geographics team members and our customers is the Esri release plans for ArcGIS for Server 10.1, and Esri’s plans to deprecate ArcIMS (details at the Esri blog).

On October 12, we will be providing a free webinar to provide guidance on migrating from ArcIMS to ArcGIS for Server. We will also demonstrate an approach that can help accelerate this migration by gaining efficiencies in the design, development and maintenance of web-based mapping applications.

Web ADF vs. RESTful APIs? Not as black and white as some might like…

People frequently ask us about our take on ESRI’s RESTful APIs in the context of Web ADF. Basically, the RESTful APIs are an important and needed technology. They also aren’t a cure-all, and sometimes Web ADF is the right path (despite its flaws, there are lots of organizations satisfied and successful with Web ADF). We consider REST and Web ADF to be complementary technologies that we envision many folks will choose to run in parallel.

I like the following analogy:

I have five deliveries for you to make. Which of the following two vehicles is better?


Folks that don’t suffer the unfortunate predilection to gravitate permanently to a black and white answer might observe that it depends. If the deliveries consist of envelopes within a ten block radius, the small delivery van is the right choice. On the other hand, if there is two hundred miles between deliveries of heavy crates, then you’re going to want the rig. Which vehicle is better for deliveries? It depends.

Prior to the final release of Geocortex Essentials 2.0 (which ships with REST, JavaScript, Flex, and Silverlight APIs), we were reticent to be too vocal in our situational defense of Web ADF lest anyone accuse us of being biased out of self-interest. However, with Geocortex Essentials 2.0 out the door we now support both platforms; every Geocortex Essentials license includes both our REST Elements and our Web ADF Elements.

Now we can be more vocal about this topic. It isn't about categorically picking one or the other. ESRI's RESTful APIs and Web ADF both have their place. The right choice depends on the nature of your app and likely evolution of that app.

ArcGIS Server 9.3 APIs Part 1

With the release of ArcGIS Server 9.3, you'll have the following APIs available for building web applications with ESRI software:

  • Web ADF (.NET and Java)
  • REST (.NET and Java)
  • JavaScript
  • Google Maps Extender
  • Virtual Earth Extender

In addition to these APIs, ESRI is also working on a Flex API and Silverlight API that will be released post 9.3. No matter what the technical requirements are for your project, at least one of these APIs should help you get the job done. But which one? With choice comes confusion. There's obvious strengths and weaknesses of choosing one over the other, as well as overlap in the functionalities they offer. Sometimes the choice is clear based on the technology stack and features you're targeting. For example, if you require a secure solution and are standardized on .NET Framework then the .NET Web ADF is likely the best choice. Over the next few weeks I'll discuss and compare these APIs in hopes of making your decision a little bit clearer, as well as share our experiences with them to date.

ESRI Business Partner Conference and Dev Summit Recap

Wow, what a conference! I spent the last week in Palm Springs with various Latitude co-workers at the ESRI Business Partner Conference followed by the Developer Summit. Steve and the account management team were busy from Saturday to Tuesday meeting with existing and potential partners from around the world. I played mainly technical support for the first couple days, assisting where I could. Ryan Cooney flew down on Monday and we spent the rest of the week at the Developer Summit, which was the main reason I was there.

So, what did we learn? On the business side, there's a real buzz about Geocortex Essentials and the work we've been up to, as Steve alluded to earlier. On the technical side, there's a few points of particular interest:

  • The .NET Web ADF at 9.3 has a number of quality and performance improvements. A lot of work has been done to support a "hybrid" model of web application develoment where you get the ease of development using client-side (JavaScript) focused technologies coupled with the power of a server-side object model.
  • It will be relatively easy to port web applications built on 9.2 to 9.3. Of course, this applies directly to Geocortex Essentials which we plan to support on 9.3 out of the gates.
  • The .NET Web ADF at 9.3 supports the .NET Framework 3.5.
  • Significant documentation improvements.
  • The new ArcGIS Server JavaScript, REST, and connector APIs make ArcGIS Server a real contender in the consumer maps arena. Although, I predict a lot of confusion around which APIs to get started with, which I plan to address in the coming weeks.

Dave Bouwman did a great job of capturing the details of the .NET ADF session as well as the others he attended, as did James Fee in his conference recap. Bottom line on ArcGIS Server 9.3 is that it looks like a great upgrade that I'm looking forward to building on with Geocortex Essentials. Finally, the two conferences were a great time and I'm already looking forward to attending next year.

The Internet will never take off because my 14.4 modem ties up my phone line

I’m an avid reader of James Fee’s popular GIS blog, and I’m sometimes tempted to weigh in with a comment, but then I wonder if instead it is best left to people wanting to vent. There have been some good discussions lately, so I decided to comment.

This is all reminiscent of everyone kvetching about ArcIMS 3.0 in the summer of 2001, before ArcIMS went on to be such a phenomenal success (overwhelming its flaws). Technology improves over time, yet so many people are ready to pass judgment before a given technology comes into its own. Or maybe we all just need a place to vent with our buddies, then get back to it.

Some reasons I like ESRI technology

We’ve been working with ESRI software for more than 7 years now. From a pure business perspective, there are many reasons Latitude has focused mostly on ESRI products. But it's not the business side that excites me -- it's the technology. Here are a few reasons I like ESRI technology:

Web ADF - I recall last summer sitting down with Steve to discuss some of the technology I played with while down at Redlands participating in holistic testing. We started chatting about Web ADF and, as I always do, I tried to think of a meaningful analogy to communicate what I thought the signficance of Web ADF was - it went something like "ADF is to ESRI server technology what .NET is to Microsoft technology." You could sit down and write all of the code necessary to incorporate ArcIMS, ArcGIS Server, OGC, and others and build a framework for map navigation, tools, querying, etc, or you could build on top of Web ADF, leap frog all the up front development and focus on your real business challenges. It's relatively new technology and has some wrinkles to iron out, but I believe it will become a core asset for ESRI. And based on discusionss I've had with Redlands, they seem on top of emerging .NET technologies for the .NET verion of Web ADF. We're putting our money on the .NET ADF.

ArcObjects - ArcObjects is perhaps the largest COM implementation in the world and has to be the most feature rich GIS library available. Put that into a server context and you've got the makings of a pretty powerful web GIS engine. Now, ArcObjects isn't the easiest, most intuitive library to program with, and it wasn't originally designed to run in a server context, but it is certainly stabilizing and we should see big performance jumps with the 9.3 release. Also, having ArcGIS Server powered by ArcObjects means that as the desktop GIS functionality matures due to technological and user driven innovations, so will ArcGIS Server.

Supporting Technology - It always amazes me how much effort ESRI goes to to support their products on so many different platforms. Windows, Solaris, Linux, Java, .NET, ColdFusion. Sometimes you get the feeling that they bite off more than they can chew - but I would rather have the option to run on my platform of choice than not run at all.

User Community - All it takes is one trip to the ESRI International User Conference or even the Developer Summit in Palm Springs to realize how many like-minded developers there are out there trying to build the same stuff you are. Or do a Google search for some Java or .NET technology only to find a bunch of hits pointing to GIS developer problems. Bottom line is that if you're struggling with an ESRI programming challenge, someone has probably solved and posted about it.
