[postgis-users] Use of Box2D (or not)

[Jan Syryn]

Hi all,

I have a table DTMTile which contains the areas that may be covered by the
satelite.
Every Tile has a 1 degree by 1 degree size.
So for sure every Tile contains 4 points.

If I have a certain footprint (geometry) of an satelite image, I am
interested in knowing what DTMTiles are applicable for this image.

Questions:
- is it a good idea of storing all the tiles as box2d ? Or does polygon do a
better job?
(if poly=better, what is the practical use of box2d then?)

- I saw some people mentioning the term 'rasters'. Is this applicable for my
case (dtmTiles seem very much as a raster) ? And if so, can someone pass me
some info how to do it (found nothing in the manual)

Thanks for your time answering this one,
Jan
