I wasn't sure if my other two questions got lost in the vector gfx discussion, but if anyone has any pointers it would be very helpful - particularly for the first question <br><br>thanks, alan<br><br><div><span class="gmail_quote">

<br>> 2. I noticed mentions of a vector graphics layer for openlayers. A<br>> project called dojo recently added vector graphic support in the 0.4<br>> release, plus a local data store cache, and documentation tools (both of
<br>> which I also saw mentioned in your Trac logs). So I was wondering if the<br>> openlayers team had seen or considered the dojo library?<br><br>Wow, I was just going to ask this as well. Have recently been in touch
<br>with some of the dojo people, specifically the <a href="http://openrecord.org">http://openrecord.org</a><br>people. We were chatting about integrating GIS functionality in to it -<br>they have a number of ways to display data through charts, and on a map
