I need a little help on WMS, it appears to decide that my one request should
be two and hence is slowing the whole thing up
I create an XML file and it has the following attributes for DataWindow:
UpperLeftX -10.2210525
UpperLeftY 57.7424
LowerRightX 4.88191
LowerRightY 51.3579
SizeX 1076
SizeY 787
BlockSize is left at default of 1024 for X and Y
When the request is issued I am noticing in Wireshark TWO requests are sent
that appear to have the following BBOX parameters:
Request 1
------------
-10.2210525
49.43529033
4.15203
57.7424
Request 2
------------
4.15203
49.43529033
18.52511
57.7424
So a couple of questions:
1. Why the two requests?
2. Why is the area that ends up in the two requests a lot bigger than the
size of the DataWindow that was requested?
3. What am I missing? Is it SizeX being slightly bigger than the block size
causing the two fetches? How can it be optimised?
