<p dir="ltr">Hi,</p>
<p dir="ltr">1) updates depend on bing, google... You may have more info on the exact images if you go on google earth for example. Updates, source and spatial definition vary from one service to the next.</p>
<p dir="ltr">2) Georeferencing is not to bad in google earth. Use an other data source for anything important. Double check always. </p>
<p dir="ltr">3) not sure.</p>

Hello,
<br /><br />I downloaded the <b>openlayers plugin</b> in oder to display several layers (Bing, OSM, googlemaps).
<br /><br />1/ These data are there <b>updated</b> regularly? I took a look in my area. And i notice that several territorial evolutions have not been taken into consideration....
<br /><br />2/ What about the <b>geometrical accuracy </b>of these data <b>(georeferncing)</b>? One of them would be more accurate than the others?
<br /><br />3/ If we want more <b>recent</b> data, are we obliged to load data via a WMS service? If it's the case, how to find the usefull URL in order to connect to each remote server (OSM/BING/ google, etc. )?
<br /><br />Thank you very much for your help.
<br />
