Grasshopper

Hello,
I wanna import topography data colllected from srtm nasa ,but the problem is that when I take latitude from osm file it shows different value that from what it really is and that is why I have n error with this message:

  1. Solution exception:Index was out of range. Must be non-negative and less than the size of the collection.
    Parameter name: index
    So maybe someone could know the solution and would help me. In below i am adding gha file and also osm and hgt file.SITEMODEL_ELK.gh (26.1 KB) OSM.zip (2.2 MB)
