Import geodesic coordinates

[jantglez]

I'm starting to get familiar with this tool and I would like to know whether it was possible to insert polygons over a list of geodetic coordinates and then assign them a height in feet?

how can I do?

thank you very much

greetings to all

jantglez,

Welcome to the SCF!

If you're talking about longitude/latitude, or theta/rho angular (spherical) coordinates for points on the surface of a sphere, SketchUp does not natively support those coordinate systems. SketchUp expects cartesian (x,y,z) coordinates.

I typically use a spreadsheet to convert from angle/vector coordinates to cartesian coordinates. I then import the cartesian coordinates into SketchUp, using a '.dxf' data file, or '.csv' file (using a ruby plugin.) Both are text data file formats. SketchUp natively supports the import of DXF files. To import a CSV file, you can download and install the "Cloud_V6.rb" plugin from this page...
Ruby Library Depot
...thanks to Didier Bur. (The plugin is 'zipped' as "Cloud_V6.zip")

The cloud plugin will import points only (i.e.; a "points cloud".) A properly-formatted DXF file can import points, lines and polygons, but, as expected, is a more-complicated file to generate with a spreadsheet.

Note that I use these methods for geodesic dome constructions (3D Warehouse - Geodesic Collection)

If you don't need to cover a spherical area, but only a small patch on the surface (such as earth longitude/latitude), then other means may be available to you. I must, apologetically, leave comments on those potential methods to others, who have more experience importing GIS and longitude/latitude survey data.
