I'm working on a project that is checking to see if distance is related to colonization by invasive species based on human activity. In order to do that, I must calculate the distances between colonized lakes and uncolonized lakes in a variety of forms. I have done this using QGIS 3.12 by using the built in network analysis run point to point, and then the QNEAT3 plugin using the OD Matrix from Layers as Table (m:n). Both result in very similar values, but these values don't have units and I am unable to figure out what they are. The layers have units of degrees, but can't be degrees. Google and StackExchange searching has not lead me to any answers, and neither did reading the manual for QGIS or QNEAT3. I could guess at meters,but a distance of 190-191 km is way to high. If it is in feet,its way to low. It's actually only about 11 miles or so between the points. I could just go with the "cost" values, but I need actual units, not values.
Doing one or two of these wouldn't be bad, but I have potentially thousands that will need to be calculated set over many states, and I don't have 5 years to do that on google.
If anyone could let me know either what the units are, or how to convert them to km or miles, or both, please let me know.
