[OSGeo-Discuss] Documenting GIS Data Models (Again): Using DXF

[Craig Miller]

Landon,

 

I missed your previous post.  I'm not sure if you are modeling GIS Objects
or a relational database but am guessing you are modeling GIS objects.
Since I missed the earlier post(s). Is there a reason why traditional OO
diagrams such as UML Class diagrams won't work for the GIS data you are
modeling?

Subject: [OSGeo-Discuss] Documenting GIS Data Models (Again): Using DXF

 

I posted a few weeks back I posted about possible ways to document and share
GIS data models. I decided to move forward with a graphical approach. 

 

I started building diagrams to document my GIS data model for the Public
Land Survey System in the United States. I am drawing these diagrams in a
CAD program. When I get things ironed out I hope to release the following
items to the GIS community:

 

-     My completed GIS data model in DXF format that can be used as an
example or template for other models.

-     A set of CAD "blocks" that can be used to build similar diagrams.

 

If I like how things come together with the diagrams, I might try converting
the diagrams to SVG. The diagrams would be much prettier in SVG, but I am
quicker with CAD than I am with Inkscape, and I want to get a prototype
completed quickly.

 

This will make a lot more sense when you get to see the example diagrams.

 

I welcome any collaboration on this effort. If there is interest, I could
move this discussion to the Standards mailing list. It would be great to get
input from interested parties now, while the diagrams are still taking
shape.
