<div dir="ltr">Marc,<div><br></div><div>The way to do this would be to overlay NGI data with our data. You could do like frutellake did and check total length in squares of 1 km². Or you could do it more properly using a data conflation tool. With something like FME I would try to find a partner road for roads that exist in NGI. In case there is no match, that would warrant closer inspection. When a road is of a completely different type in NGI and our data, that would warrant a check too.</div><div><br></div><div>I did this in a purely visual way with Wegenregister, which is mostly NGI but only Flanders, and there were places where NGI was more complete - and places where we are more complete.</div></div><div class="gmail_extra"><br><div class="gmail_quote">2015-11-12 11:27 GMT+01:00 Marc Gemis <span dir="ltr"><<a href="mailto:marc.gemis@gmail.com" target="_blank">marc.gemis@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Nov 12, 2015 at 9:43 AM, joost schouppe <span dir="ltr"><<a href="mailto:joost.schouppe@gmail.com" target="_blank">joost.schouppe@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> if only to check for missing roads in our map (especially the "slow roads" still need work in Belgium).</blockquote></div><br>You have to be careful with this.
