Dear all,<br>
<br>
I 'am working on coastline 's dynamic at different periods. For each period<br>
and from satellite coverages i captured multilines shapefiles representing<br>
the coastlines.<br>
<br>
Now i would like evaluate & caracterize the spatio-temporal evolution.<br>
According to you, is there a tool in qgis in order to "characterize" the<br>
difference (meters) between  linear shapefiles? Maybe it's possible to<br>
generate easy stats from the geographic coordinates points constituting<br>
multilines ?<br>
<br>
If you can throw light for me ?<br>
<br>
With kind regards.<br>
<br>
<br>
