Subject [jira] [Commented] (SIS-8) Build a common SIS data container for spatial data
Date Mon, 16 Jul 2012 12:40:34 GMT


Peter Karich commented on SIS-8:

@chris & @eric thanks. now the definition makes sense and should cover a lot. I'm still
struggling to define use cases up front without the use cases implemented :) (btw: where is
the source of those classes?)

that said, I would add at least rectangle ( and circle (
For the rectangle it could be important to use one of the standards:

> The QuadTreeNode has the concept of a data container per node in the QTree, but I'd like
to extend this to a general SIS spatial data type. This would in part be motivated by e.g.,

time interval of measurement);
