I’ve been searching and testing pluggins alot (meerkat, elk, gismo, terrain generator (LB), Ghowl) on how to create a site that automatically models itself in grasshopper close as what we have acces in Google earth pro. And then, I could perform urban bioclimatic analysis with ladybug.
The goal is to create into grasshopper/rhino:
- An high resolution topography with texture mapped on. (1m contour curve at least, or something similar)
- 3D buildings with correct height according to topography
- Trees as simple boxes
- Roads to project on topo
The Main problem is where to get accurate information to model the site. OSM files (openstreetmap) are often incomplete (except in big cities); Shapefile (.shx, .dft, .shp) are difficult to find with all the information you want (especially buildings heights).
Should I look at other file format more accurate ? I’m thinking of :
Do you know more about other plugins in Grasshopper which can handle these files formats ?
Is there another way to get around this ‘‘lake of information’’ issue ?
Do you have any food for thoughts / links so I can keep exploring this subject ?!!
Really appreciate !
