<div class="WordSection1">
<p class="MsoNormal"><span style="font-size:10.0pt">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
<br>
I create an XML file and it has the following attributes for DataWindow: <br>
<br>
UpperLeftX -10.2210525 <br>
UpperLeftY 57.7424 <br>
LowerRightX 4.88191 <br>
LowerRightY 51.3579 <br>
SizeX 1076 <br>
SizeY 787 <br>
<br>
BlockSize is left at default of 1024 for X and Y <br>
<br>
When the request is issued I am noticing in Wireshark TWO requests are sent that appear to have the following BBOX parameters:
<br>
<br>
Request 1 <br>
------------ <br>
-10.2210525 <br>
49.43529033 <br>
4.15203 <br>
57.7424 <br>
<br>
Request 2 <br>
------------ <br>
4.15203 <br>
49.43529033 <br>
18.52511 <br>
57.7424 <br>
<br>
So a couple of questions: <br>
1. Why the two requests? <br>
2. Why is the area that ends up in the two requests a lot bigger than the size of the DataWindow that was requested?
<br>
3. What am I missing? Is it SizeX being slightly bigger than the block size causing the two fetches? How can it be optimised?<o:p></o:p></span></p>
