Hello, I would like to ask if anybody knows how to do a able-top exercise to illustrate the workflow of geo-spatial data sets and calculations (or computational flows) are done by each step. Thanks!
emulate one of the workflows in modelbuilder... and if you really mean table top aka manually then you just need bubbles and strings.
What is ModelBuilder?—Help | ArcGIS for Desktop
Hi Dan, thank you for your promptly reply.
I was also thinking to use ModelBuilder. However, I have one more question. The reason that I am asking about how to do a table-top exercise is because, one the one hand, I need to have an example small enough to manage by hand and see each step and connection but sophisticated enough that it illustrates the complexities of the computational calculations.
On the other hand, I then have to present this workflow (in terms of steps from concept to results, such as how I generate a large-scale geo-spatial data set, and run statistical models using these data sets) to audience who are not in my field (i.e., people who have no idea what ArcGIS is and what specific terms mean). Thus, I am wondering whether or not modelbuilder is the most effective tool to solve my problem.
I am serious about doing it by hand on a table! This will keep you out of dealing with the realities of modelbuilder when trying to work with those that are noobs. If you have some coloured ovals etc, then the tool names that are from within Arctoolbox can be labelled. Put all this on a large piece of craft paper (a couple of feet square and you can work together to develop a workflow manually, organizing the tools, marking which need to be parameters, whether iteration needs to be done etc etc.
THEN when people are in agreement on the paper model, move on to the computer and get them to implement it in Modelbuilder... then move on to a conventional tool for arctoolbox... the possibilities are endless...
I have a couple of blog posts... I will update this post

I see...Would you please share the link for your post?
What about boxes (or just paper shapes) as say your polygons, some string as your lines, balls (that you can open up) as your points and marbles that you can put inside your balls as your attributes for your points? You could then do some spatial statistics work based on this as you'd have all the elements. I like the idea of you maybe have two boxes that each have 3 balls inside. But when you take into account marbles/attributes you might see that the balls in box 1 have more marbles inside or more of a certain colour or size.That way you can tell the story that visualization is one thing but can be totally different once you consider the attributes of each of the elements.You can then bring in different statistics measures, or bring in string/lines to split the boxes/polygons. You could also use your props to talk about topological relationships. And you can always throw a paper map underneath it all to act as your base map.
