I just installed the new version and did quick tests. With these changes, significant speedup is also visable in other functions: 1. `st_sample()`: 13.8 s -> 8.4 s (40%) 2....

@spono, did you try to use [virtual raster](https://rspatial.github.io/terra/reference/vrt.html) and then save as a single file? For this, tiles must be stored on disk, not in memory.

Try to turn off the spherical geometry engine as workaround: `sf_use_s2(FALSE)`; or transform the coordinate system to plannar: `st_transform()`.

> Timeout of 60 seconds was reached There is a problem with the Internet connection or servers. Try to set up before downloading: ```r options(timeout = 600) ```

There are several workshops and presentations from Edzer Pebesma on YouTube (just type his full name to search): - [Handling and analysing vector and raster data cubes with R](https://www.youtube.com/watch?v=9by7zsGms40) -...

Hi @btupper, here is a little self-promotion, but you might be interested. I taught workshop on [OpenGeoHub](https://opengeohub.org/summer-school/siegburg-2022/) this week comparing/benchmarking spatial packages in Python and R, and one part is...

Did you try to use `{terra}` or `{exactextractr}`? They return some values. ```r library("sf") library("terra") library("exactextractr") myurl

Just use `cbind()` to combine geometry with attributes: ```r v = read_sf("./counties_florida.shp") df = extract(fg10, counties, fun = "min") v = cbind(v, df) # combine sf and dataframe ``` ```r...

It seems that as workaround, this file can be loaded using the `{tiff}` package. Should this file contain a spatial reference? ```r library("tiff") library("stars") tif = readTIFF("sample_tiff_8bands.tiff", all = TRUE)...

I refresh this thread because I did some benchmarks between **stars**, **terra** and **exactextractr**, and as a result **stars** is the slowest. I think this issue is worth exploring more....
