Thanks for the comments. I will answer below:<br><br>> - not taking in account building levels<br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I think this information is quite interesting (for making 3D Models),<br>
in other regions people are investing a lot of work to survey these<br>
(and to split the buildings accordingly). Strange you decided to not<br>
use this information. Maybe it wasn't precise or current enough?<br></blockquote><div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<br>
<br>
tracing atomic areas is also something we are doing in some regions<br>
manually. IMHO you are destroying a lot of interesting information by<br>
unifying these. The actual landuse is much less interesting than the<br>
size and layout of the areas/plots. Its the layout that tells the<br>
structure, and often also history, of the rural areas. Wouldn't do<br>
this.<br>
<br></blockquote><div><br>I will answer these two point at the same time:<br><br>The tool can import these data too, but the last time we discuss here there were LOTS of opinions against these. We agree with you, and internally we are using that information but from our point of view it a decision that the local mappers must take. In [1] there is the same same town but with building 3D data and rural parcels. In this case you will not notice much differences as this is a very small rural twon where the buildings have normally one level. In [2] and [3] you can see Cadiz [4] a big capital from the south of Spain with [3] and witout [2] the 3D information. <br>
<br>In fact we can also have the all the historical changes but we do not know how to code this information without completely screwing the actual data. I am not sure about the acuracy of data previous to 2000 but we can extract it. Exists any propousal in this direction?<br>

<br>
I guess you wanted to say: "remove the parcel"?<br></blockquote><div><br>In this case it does not matter what you have deleted because they sahre the same geometry and tags :P<br> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
