I have my rhino measuring in meter, and zoom out to see that there is a rectangle approx 20,000x15,000 m.
About the folder path I can not figure out what you mean, tried to google it but could not really find out what you meant. Sorry 
And pressing that button does not help, nothing happens at all for me unfortunately
On the RESTRaster component I get error message
- Solution exception:Input parameter index [-1] too low for Component Get REST Raster.
On the ImportTopo I get error message
- Solution exception:C:\temp\SRTM GL1 (30m)_0.tif: No such file or directory
On the SurfaceMap, PreviewMat and Contour component I get the error message
- Input parameter M(or S or G) failed to collect data
EDIT: I can see that when I press the button the coordinates changes depending on which location I type in, so there is probably nothing wrong in this component.
