Sorry, its my issue I am thinging about polygons, but for me
would be enought points.
The problem is next. I am writhing geo portal where user can
draw shape. I need to get users images that user shape cross.
But as temporal solution it would be enough to detect if image
central point inside this polygon (I know its coordinates).
I can do its on DB level, but I would like to use SQLite that
do bot have geometry support. So i am looking for any solution.
I can use gdal but its _very_ heavy
So when you say you want polygon intersection, is one of the
polygons you are interested in the shape of the images (ie.
roughly a rectangle)?
If this is the case then you can likely just take the bounding
rectangle (easily calculated) of your polygon and check if that
intersects the bounding rectangle for the the image and that
should work 95% of the time.
