Coordinates

[jarkwiat]

Hi, I feel a bit silly asking this, but I've been struggling for so long and haven't found an answer anywhere. I'm looking for coordinates on a map. I have a geodetic point set up and I'd like to place a few trees with specific coordinates in relation to it. How do I do this? I used Google Translate, so I apologize for my English 🙂

Hi,

If I understood correctly - you want to place a tree you know the coordinates of?

Firstly, you have to define your project origin in relation to world coordinates. Let's say project origin is at the X Y coordinates you have in your image. 

And then you can do some calculation based on that, to calculate the distance on X and Y axis from the origin to place your tree. 

You can place this object from the library to double-check the accuracy:

and place as many of these as you want. Afterwards you can replace them all with trees.

Thank you for your quick help, I'll try it right away and let you know 🙂

I tried, but it seems I have the wrong data, as you can see in the attached image. Thank you for your help - I understand what the settings are, but I need to solve this problem with the tree map service provider.

I wonder if this could be done with the Archicad-Grasshopper connection.

Here is how this could work:

You could have a text or other file containing the X,Y coordinates of the trees.

Grasshopper would read those X,Y coordinate pairs and place "Tree" Library Parts at those X,Y coordinates.

If you had a 3D terrain geometry in Archicad, you could go even further to place the Trees on the Terrain.

To do this, you could bring into Rhino/Grasshopper the 3D terrain geometry from Archicad, use the Archicad Deconstruct Components in Grasshopper to extract their top surface, and then for each X,Y coordinate pair, find the Z coordinate of the terrain, and place "Tree" Library Parts at those X,Y,Z coordinates. This way, all placed Trees would be on the top surface of the terrain.

Based on your screenshot it looks like you are trying to work with longitude and latitude. You would need to work with Eastings and Northings as these are a flat plane x and y mapped co-ordinates. 

With those co-ordinates you could then determine to co-ordinates of each tree relative to your Archicad origin and place each tree manually. 
To automate the process of placing the trees based on their co-ordinates you would need to use grasshopper (or maybe python/tapir) as Laszlo described.

Thank you guys, I have a lot of work ahead of me but I'll try and let you know !
