st_make_grid makes grid that does not intersect with all points

4

I've had an intermittent bug appear in code that use to work (documented here https://github.com/ropensci/stplanr/issues/466) The problem is occurring because ``` sf::st_intersects(p, sf::st_make_grid(p, what = "polygons")) ``` returns empty values....

Wrapping polygons around dateline while respecting spherical geometry

5

Good day all. I have multiple sets of four points (forming `MULTIPOINT` geometry), from which I would like to create a convex hull polygon. A number of these sets of...

Problem for extract mean values between same coordinates in different csr

1

I have a data set extracted from S2 satellite rasters (10 x 10 meters) with 12 values (`ras.df.ll`), but 6 is in a tile (`T21JYG`) and the same 6 coordinates...

st_crop and st_intersection do not cut decimal degrees assuming planar cartesian coordinates

Apologies for opening a new issue. Please close if already solved. I thought this was a feature of `sf` and therefore made an SO question: https://stackoverflow.com/questions/69027136/how-to-crop-non-projected-epgs4326-polygons-along-straight-lines After studying the behavior...

st_difference broken with S2 on?

2

Updating to sf 1.0 or 1.0-1 breaks some of my code when (and only when S2 is on). One issue is that `sf::st_difference` now behave differently: ```r library(sf) # Linking...

st_make_valid failing to make geometries valid

4

I'm analysing species distributions within Australia. Some of my geometries are invalid, and are not able to be made valid using either `st_make_valid` or `st_buffer`. I subsetted the troublesome invalid...

s2 much slower than sf with st_union in epsg 4326

1

Hello, Writing the following operation, I get much slower runtime using `s2` using the 4326 projection ``` r library(sf) #> Linking to GEOS 3.9.0, GDAL 3.2.1, PROJ 7.2.1 sf_use_s2(T) shp...

`st_dimension(x)` copies its input into an OGR geometry type. In a test of 100,000 point-in-polygon intersections, this takes ~25% of the runtime:  It seems like the topological dimension could...

sf 1.0 will switch to using S2 geometry for ellipsoidal coordinates

66

As announced [here](https://www.r-spatial.org/r/2020/06/17/s2.html#sf-10-goodbye-flat-earth-welcome-s2-spherical-geometry) in June last year, and also in the NEWS file around the same time, it is planned that where possible `sf` will use the spherical geometry operators...
