<div dir="ltr"><div><div><div>Hello,<br><br></div><div>I think I'm doing something wrong with importing lidar data in GRASS 7. <br><br></div><div>My data is a laz file from the state of Minnesota. <br><br>The complicating factor is that the EPSG code is set incorrectly -- EPSG:32715 / UTM 15 S instead of EPSG:26715/UTM 15 N. My region is set to the correct 26715. <br>
<br></div><div>I am using the GUI, but the command that it generates is<br><br>v.in.lidar -p -o --overwrite input=/data/3542-27-22.laz output=test<br><br></div><div>The output is: <br><br>Over-riding projection check<br>
