I often calculate the altitude of an observation before I make an identification. This is useful for determining the reasonableness of observation data, and in some cases the altitude can provide direct evidence for (or against) the species in question. I asked about the altitude of observations be…

you could always use an API like USGS’s elevation query service (which should cover the USA, see https://nationalmap.gov/epqs/ for more info). for example: https://nationalmap.gov/epqs/pqs.php?y=35.587842&x=-83.363864&output=json&units=Meters alternatively, if you just want to get a rough idea of a…

This may not be as optimized as you are wishing for, but I have successfully used the tools linked at https://www.gpsvisualizer.com/elevation These are especially handy for bulk lookup of elevations for large sets of coordinates, but there are also forms for looking up a single coordinate pair. C…

[image] pisum: you could always use an API like USGS’s elevation query service Thanks for the links and the sample code. If I had a batch of altitudes to compute, this would probably be the way to go. [image] jdmore: I have successfully used the tools linked at… Thanks. The “quick sin…

[image] trscavo: I asked about the altitude of observations before but let me say up front that inspecting the contour lines of the google map is not an option. It just doesn’t work. I don’t know if that’s a bug or user error. Plugging in the coordinates somewhere else can sometimes just be …

[image] bouteloua: Are the contour lines not showing up at all? The contour lines appear if I zoom in just the right amount. However, given the size of my screen and my marginal eyesight, it’s just not feasible for me to determine the altitude from that. It’s a usability issue. [image] bo…
