<div class="yiv1363542427MsoNormal">Hi all,</div>
<div class="yiv1363542427MsoNormal">I’m currently working on porting the custom select tool to GeoMOOSE 2.6. The customizations enable direct interaction by using vector features for the selection result (instead of rendering a raster image). This makes it possible to e.g.
highlight an individual feature by clicking an icon in the result list. In the old custom code the service sent back commands to create the vectors in the <script> result of the service. I could replicate this but would like to propose utilizing a WFS layer
instead. This could be done in at least two ways:</div>
<div class="yiv1363542427MsoNormal"> </div>
<div class="yiv1363542427MsoListParagraph" style=""><span style="">1.)<span style="font:7.0pt;">
</span></span>We could change the highlight layer in the mapbook to be a read-only WFS layer. This would also mean altering the highlight.map template in htdocs/php/select/ to enable WFS requests. select.php would work more or less as it does now
(but some of the rendering commands it sent back would be different).</div>
<div class="yiv1363542427MsoNormal"> </div>
<div class="yiv1363542427MsoListParagraph" style=""><span style="">2.)<span style="font:7.0pt;">
</span></span>We could try to utilize the OpenLayers GetFeature control which can be used to directly transform interaction with a WMS layer into WFS requests (see
http://openlayers.org/dev/examples/getfeature-wfs.html). This would require the user to enable WFS in the mapfile for each layer they wanted the select service for. Since WFS supports spatial
filters, select.php would not be used (but we would need to a different way to render the HTML).</div>
<div class="yiv1363542427MsoListParagraph"> </div>
<div class="yiv1363542427MsoNormal">Either of these options would to need be configurable so that the current raster-based approach would still be available (especially when there is a potential for large selection result sets).</div>
