Hello Igor,

Not clear on what the issue is.  What is it you are expecting to get?

best,

Luis

Hi Luis,

Thanks for everything! I really do not want to be annoying.

I followed your instructions:

 I divide PictureFrame as Surface into number of points. I pluged this points into XZY – GEO Node, also one reference point to in order to get elevations data. Then I decomposed points and made them again with new Z lengths. Build a IntCrv and loft it. Works fine.

Now, I culled the lowest point in a list (with sort list) . Put a XY Plane trough, duplicate it with Series and specific number 2.0 and intersect this planes with lofted surface, in order to get isohypsen. Works also fine.  

I am just not sure, that with this way , intersection,  I get really thing!?

City is Graz (AU)

Thanks a lot one more time !

What I do is to bring in a screenshot from Google Earth through the picture frame command in Rhino, I scale it according to the scale indicated (to 1:1) then I pick a point in XYZ which I can easily look up in google earth, such as a sharp corner.  I bring in the xyz to gh, and I write in a panel its corresponding {lon,lat,0}.  You can then use the XYZ>GEO component to convert any points you draw or generate in Rhino / GH from XYZ coordinates to {lon,lat,alt} coordinates.  You can now feed these into the elevation component.

Or to draw a GPS route with http://www.gpsvisualizer.com/draw/

and use that for coordinates and terrains line...

I will try this one..

Still if you have some cleaner way, I am open :)

Thanks

Thanks for that!

How do you get a list of a points (coordinates), do you manually draw them on google earth map with placemaker, than read a coordinate and then assign them in a GH?

I hope not :)

I manage on this way, following your explanation somewhere in forum, to send a model in to google earth.

Thanks

Hello Igor,

The Elevation Service needs you to provide a coordinate like this:

{longitude,latitude,0}

*notice the brackets, it is formatted like a GH point.

Longitude and latitude are in decimal degrees.  The component returns the elevation at that point.  Let me know if you need any more information.

Hallo Luis,

Can you maybe explain a GetElevation option.

Do I need to get familiar with google maps Api pr. and get data from them, and than plug this data to GE node?

Thanks

Igor

Hello Lauren,

Open Office is not necessary anymore.  Everything you need should be in the gHowl download.  Check out the 'Dependencies' folder for an installer which will enable spreadsheet functionality.  Which version of Rhino/Grasshopper/Windows are you using?

Comment by Lauren Campbell on October 13, 2011 at 1:01pm

I've downloaded Ghowl several times along with the open office and the other thing it says you must have and still can not figure out how to get the components in GH

Any help would be fantastic

Elise, very cool!  Can you let us know a bit more about this?  Was it as simple as 'plug and play' or did you run into issues along the way?  I wonder how this would operate with multiple users, 10, 100, 1000, etc!  How does the architecture negotiate that information?
