<div><span class="e" id="q_111f0facd40ee012_0">Hello,<br><br>I developed a web application with an interactive map using OpenLayers. <br>At the beginning I chose OpenLayers and not ka-Map beacause throught OpenLayers I was able to overlap and integrate different layers, like:
<br>- 2 WMS layers (originated by MapServer based on an shape files archive on my server)<br>- 1 WFS layer (originated by MapServer that queries my database getting a set of points localized by GPS)<br>- 1 layer coming form Google that allows me to get simply satellite maps of the planet.
<br>At the end I chose OpenLayers above all beacause it allows me to use also the Google Maps.<br>Now I would have two important questions: <br>1) I know that the Google Maps License permits to get the maps only using the API. Someone can explain me how OpenLayers is able to get the Google Maps without using the API? Are there some license problem?
<br>2) OpenLayers does not have a cache tiles system like ka-Map. How can the interaction (zoom and panning) be so good also without this system? <br><br>Your help could be very useful beacause i did not find good material or papers about OpenLayes.
<br>Cheers,<br>Francesca <br clear="all"><br></span></div><span class="sg">-- <br>Ilaria Gelsomini<br>Francesca Pedrazzi </span><br clear="all"><br>-- <br>Ilaria Gelsomini<br>Francesca Pedrazzi
