Originally posted by **Phome95** May 21, 2022 Hello, I am attempting to use the silva2016 algorithm: ```r library(lidR) library(raster) chm <- raster("chm_clean2.tif") ttops <- locate_trees(chm, lmf(3)) crowns <- silva2016(chm, ttops)() ``` however this error comes up: ``` Error in geos_op2_geom("intersection", x, y, ...) : st_crs(x) == st_crs(y) is not TRUE ``` However both coordinate systems are the same. :link: [download data](https://drive.google.com/file/d/1pzQ3crlBwp3LS-vvqoPef8V_io1W-Iq5/view?usp=sharing)
