I can see that I hit a chord with my post about software standards, and
that if nothing else,I generated some good discussion. I hope the end
result of this discussion will be positive. At best we will find
consensus on some issues and will be able to work on improving things.
At worst I hope we will have a better understanding of the different
perspectives on software standards.

 

I'm afraid that I won't be able to individually respond to all of the
e-mails that I got with comments on my post. There where at least 20 of
them, and several were sent to me off the list as well. I will try to
read through the messages and respond to the some of the points that
were made on my blog. I agreed with many of these points and disagreed
with a few. I also changed my opinion on a couple of the issues after
reading several of the comments, which I think is a great.

 

I'm almost afraid to blog anymore on these topics, after realizing how
narrow my own perspective can be.

 

Thank you to all for taking the time to read the post and for taking the
time to make well-though responses. I appreciate being a member of these
communities.

Let's examine this (alleged) Google Maps / WMS schism a bit more. I'm  
not sure that the two compete at any level lower than "well, we both  
serve up maps via a web browser."

The WMS spec gives us complete customization of the map (bbox,  
projection, map layers, styling, image format).
Google maps uses canned vector and raster layers that offer zero  
customization choices. There is no way to provide your own base layer.

WMS allows us to seamlessly merge map data from disparate sources  
(provided they implement the spec correctly).
Google maps provides great support for "red dot fever" (overlaying  
points), ok support for lines (you can draw arbitrary lines, but not  
have them 'snap to' roads segments), and historically weak support  
for polygons (although this seems to be improving with the recent  
addition of KML support).

WMS offers zero caching solutions -- since each map is a unique work  
of art, customized to the Nth degree, caching is not a real  
consideration.
Google Maps is a brilliant example of how caching, tessellation,  
ajax, et al can bring a desktop-like user experience to the browser.

Let me be perfectly clear: I think both are brilliant at what they  
do, and I use both on a daily basis for customers and myself. They  
are, however, two different solutions for two different problems.

At the end of the day, arguing that one is ultimately better than the  
other is naive. They represent the opposite ends of the web mapping  
spectrum. GM optimizes for mass consumption (caching, performance).  
To do so, they sacrifice customization. WMS optimizes for  
customization. To do so, they must sacrifice caching. When I am  
gathering requirements with customers, these are the discussions we  
have. If the data is relatively static, let's cache the hell out of  
it and gain the speed (either using GM or a GM-like tiling strategy).  
If the point of the app is to allow the end user to compose a map  
from disparate sources, there is less we can do in terms of caching.  
Let's leverage the native customization capabilities of WMS.

I am working with one transit authority right now that wanted to use  
all of their own data (vectors, aerials), host it in-house on their  
hardware, but still provide a Google Maps-like user experience.  
Beyond what GM can provide, for a specific subset of the users they  
want to provide the ability to turn map layers on and off and do  
distance measuring on the screen. All of their data is in state  
plane, and they want to keep it in that projection. I've put together  
a PostGIS + GeoServer (WMS) + Tilecache + OpenLayers solution that is  
due to go live in the next month or so. Problem solved.

I'm in talks with another transit authority that is a very small  
shop. They don't want the hassle of hosting their own data, managing  
their own hardware, etc. They want a turn-key solution. Google  
Transit seems to be the right fit there. Problem solved.

No golden hammers here. Right tool, right job. SImple as that.

Are WMS/WFS/GML/et al flawless? Far from it. (Although neither is  
Google...) Is Google innovating at light-speed compared to the OGC?  
Absolutely. But should a standards body be expected to release a new  
spec every 3 months? Could the industry keep up, or would the OGC  
catch equal amounts of different grief for that?

All are interesting questions, but far different than the "WMS sux --  
GM roolz!" hypothesis originally posted. (grin)

This looks like it could be some pretty cool technology: 
http://link.brightcove.com/services/player/bcpid932579976?bclid=932553050&bctid=933742930

It's a preview and demo of Micorsoft's "Surface Computing" interface and 
it looks like it's step in the right direction. Of course, they don't 
talk about how accessible the interface will be, but the concept looks 
good to me!

The only thing better would be a 3D holographic interface, but I imagine 
that's coming too someday soon.

Here is the other side of the coin. Kinda funny, and makes some good
points.

Here's another company on that train.

Watching the demo a few times makes be pretty negative. It is the same 
thing over and over and over again, with different subjects.

- Zoom in
- Zoom out
- Rotate
- Move

They've re-invented the mouse, only it is way more expensive, and just 
slightly more ergonomic (once you've learned the gestural syntax).

One thing you see very little of is... words. The things we spend 95% of 
our time working with on our computers.

There's perhaps a few niche uses that are going to find this hugely 
helpful, both in terms of the large format and the somewhat cleaner 
interface to the data, but I don't see a revolution necessarily in the 
offing.

That's probably true. (I wonder what will happen when you flip off your
table top? Will you get the blue screen of death?) :]

I think the potential for map navigation is pretty cool. I was
especially intrigued by the navigation of the globe that I saw in the
Popular Mechanics Video. I can't tell you how many times I have to print
30 24" X 36" color sheets for an emergency meeting. It be great if my
boss could just pull up a digital map in the conference room table or
wall and take it for a spin with the touch of his hand.

But, like you said, this is a niche market, not a mass market.

Perhaps the real potential in this idea is the integration of computers
into everyday objects with a flat surface. Once you remove the need for
a mouse and keyboard you can start putting computers in some pretty
interesting places. Just a thought... 

I'm curious how Linux will keep up and/or adapt to this. It seems like
it would require a pretty major overhaul and/or extension of the X
Windowing system. I don't know if that will be possible if it is a
system Microsoft is developing. Could we get into a situation where
Linux is excluded because of proprietary hardware like it is with some
graphics cards?

I also wonder if we'll ever see support for that type of interface in
Swing/SWT. It is interesting to consider modeling user interface events
generated from multiple screen interactions. You might have events like
"DoubleInputPush" or "DoubleInputClick".
