Hi All,<br>
<br>
I'm curious if you could give me an idea of the level of effort this would take. I have access to a data service at work that will render an array of values in response to a bbox geographic query. I'd like the ability to create a Mapserver raster Layer that uses this service as a data source, so that I can populate a web map using dynamically generated data, rather than pre-rendering a raster set. How hard would it be to write a new "connector" that could read this data service?<br>
<br>
Thanks in advance for any advice you can give me,<br>

It should be reasonable easy to add this as a new GDAL format driver,<br>
or alternatively as an extension of the existing "WMS" driver which<br>
has a "minidriver" mechanism to add new web service types beyond<br>
WMS.<br>
