Modelling on exact GPS-coordinates
-
Being intrested in modelling on exact GPS-coordinates, the window-->model info-->location isn't enough. This as I'm particularly intrested in landscape modelling, thus modelling on large surfaces (thus very large margin of error; ideally I would like to work correct upto 1 m). I was thinking of thus either:
-
using the above method + excel spreadsheets (for determining relative location) --> see http://www.google.com/support/forum/p/sketchup/thread?tid=7437d98c8fa487f5&hl=en I'm not sure how this needs to be done though + the margin of error seems quite large
-
or by altering the kml textfile myself -->perhaps by swapping the <altitudemode> tag by another tag which is capable of supporting 4 GPS coordinates; ie LatLonQuad, ... Since this too is not sufficient, perhaps 2 modells can be determined, in the form of Model id="building" followed by the 4 coordinates, and Model id="soil" followed by the 4 coordinates. "Soil" would then be solely the soil surface (which can be flat or with gradience, ie by using the sandbox tools. "building" is offcourse the building, standing on the soil surface.

or by using ruby's ?
ie
- Cloud V6/V7.1 --> http://rhin.crai.archi.fr/rubylibrarydepot/plugin_details.php?id=72
- points_cloud_triangulation.rb
--> http://forums.sketchucation.com/viewtopic.php?f=18&t=4276&sta
--> http://markmail.org/message/swwwy5qayrvlqqzi
Of the last method I also don't quite understand how to do it.
Any help ?

Well, imnporting your terrain from Google Earth will automaticaly geo-locate your model. Then do you want to continue working in GSP type coordinates after that? Or what are you trying to get at? I'm a little confused by all the different options you posted. What do you need? A tool that lets you enter coordinates instead of lengths and distances?
