Hi Alexandre,<br><br>You are giving me lots of new ideas. One of them will be only to make editable poligons at a certain resolution, for the rest of resolutions, WMS version will be available. That's the way to avoid performance problems when working with a high populated layer! very nice<br>
I am taking a look closely to all examples and info you sent me and I will let you know my opinions about them when I have studied them better. Also, I will let you know my progress which will go in the direction you recomended me.<br>
For the moment, I just wanted to thank you very very much for your help and guide.<br><br>Kind regard,<br><br>Toni M.<br><br><br><div class="gmail_quote">2011/5/13 Alexandre Dubé [via OSGeo.org] <span dir="ltr"><<a href="/user/SendEmail.jtp?type=node&node=6369053&i=0" target="_top" rel="nofollow" link="external">[hidden email]</a>></span><br>

Hi Toni,
<br><br> Thanks for the inputs.
<br><br>=== tips and tricks, performance, etc ===
<br><br> 1) WFS-T feature editing requires a certain degree of precision. It
<br>is not really relevant to do so in smallscales. So, you could setup
<br>your vector layer to be visible and editing widgets to be usable only at
<br>certain zoom levels. That way, you would display less features, thus
<br>making the application faster.
<br><br> 2) On smaller scales, you could show a WMS version of this layer
<br>instead (non editable, but at least shows something to the user).
<br><br> 3) Also, you can read your features from TinyOWS in JSON instead of
<br>GML. That makes the requests go faster.
<br><br> 4) Read the server tuning wiki page from TinyOWS.
<br><a href="http://www.tinyows.org/trac/wiki/ServerTuning" rel="nofollow" link="external" target="_blank">http://www.tinyows.org/trac/wiki/ServerTuning</a><br><br><br>=== demos ===
<br><br> Here's a bunch of old and recent demos that could help you create
<br>what you want :
<br><br> a) WFS-T demo using OpenLayers only and TinyOWS. This demo is old
<br>and use old customized versions of OpenLayers and TinyOWS. At least, it
<br>demonstrates 1) and 2) above.

<br>Much more "up-to-date" that previous one. Demonstrates the 3) above.

<a href="http://tinyows.org/trac/wiki/OpenLayersHowToTransactional" rel="nofollow" link="external" target="_blank">http://tinyows.org/trac/wiki/OpenLayersHowToTransactional</a><br><br> c) FeatureEditorGrid from GeoExt.ux. This widget allows the editing
<br>of vector features using GeoExt and Ext libraries. It can be adapted to
<br>WFS-T.
<br><a href="http://trac.geoext.org/wiki/ux/FeatureEditing" rel="nofollow" link="external" target="_blank">http://trac.geoext.org/wiki/ux/FeatureEditing</a><br><a href="http://dev.geoext.org/ux/geoext.ux/ux/FeatureEditing/examples/feature-editor-grid.html" rel="nofollow" link="external" target="_blank">http://dev.geoext.org/ux/geoext.ux/ux/FeatureEditing/examples/feature-editor-grid.html</a><br>
<br><br>=== WFSTFeatureEditing ux ===
<br><br> I'm currently working on a GeoExt.ux tool that automatically creates
<br>every components required to do WSF-T. I have a wiki page, demo and
<br>some doc. It's all non-official (still in development) and not in
<br>GeoExt.ux (yet ?) but you can take a look. I'd suggest that you read
<br>the wiki, then the sample documentation to know how the widget works.
<br><br> Basically, it uses the FeatureEditorGrid (mentioned in c) ) and
<br>doesn't show anything on load. You need to draw boxes in order to make
<br>the vector features appear, thus making the navigation faster and only
<br>shows what the user wants to edit.

<br> Don't hesitate to give comments, suggestions, etc.
<br><br><br>Kind regards,
<br><br>Alexandre
