Grasshopper

algorithmic modeling for Rhino

This components allow you to generate a topographic mesh from USGS *.img and *.hgt file types which is then located and scaled in the Rhino/Grasshopper environment. Heron can be found at food4Rhino.

Sorry Brian for replying this late, the coordinate you gave was the coordinates of el rocio, but still the same problem.

Try the n37w007 file instead of n37e006.  The "-" part of LON -6.48... indicates the location is in the western hemisphere.  The file you linked to do have some topographic data, it's just in north Africa

I have tried the anchor, only the outcome xypoint shown,with the box I set, but no any image to be seen.

I was wondering would that happen to be the problem with the source file of that coordinate n037e006, that is not actually collected into the data base. Because I also ran this same .hgt on another plugin, ELK, and the result was a grid of points, all null result. However, on open street map, 10m contour lines are shown.

Jelenkovic,

The error message means your input boundary is not completely within the boundary of data from the HGT file.  If any part of the input boundary is outside the data boundary, you will get this error.  You should be able to see a rectangle which describes the boundary of data from the HGT when you use the Topo component.  If you do not see this boundary, it may be because you need to adjust your EarthAnchorPoint to get it within your viewport or you need to do a zoom extents.

Let me know if this helps.

I have received the following message

1. One or more boundaries may be outside the bounds of the topo dataset.


when i imported a *.hgt file with coordinate N37E06

So I went on and downloaded a .hgt with coordinates same as in your example and the same message pops up. Could you please kindly assist me here with this issue? Thank you

I apologies for i am still a amateur in this plugin
