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

    [ https://issues.apache.org/jira/browse/SIS-8?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13415063#comment-13415063

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 (LatLonRect.java) and circle (LatLonPointRadius.java).
For the rectangle it could be important to use one of the standards: http://osgeo-org.1560.n6.nabble.com/Boundingbox-issue-for-discussion-td3875533.html

> 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.,
[1], where the suggestion is something like:

> Any measurement we take in Earth and environmental sciences, although this is often ignored,
has a spatio-temporal reference. A spatio-temporal reference is determined by (at least) four
parameters:
> 1. geographic location (longitude and latitude or projected X,Y coordinates);
> 2. height above the ground surface (elevation);
> 3. time of measurement (year, month, day, hour, minute etc.);
> 4. spatio-temporal support (size of the blocks of material associated with measurements;
time interval of measurement);
