cell-abstraction mode

6

I'd love to see a "cell-abstraction" version of fasterize that returned the cell number of object/s, as a classified data frame i.e. cell, polygon-ID. This is awesome because - overlapping...

In R, I see ```R vapour::vapour_vsi_list("/vsizip//vsicurl/https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/50m/raster/NE2_50M_SR.zip") [1] "NE2_50M_SR/" "NE2_50M_SR/NE2_50M_SR.tfw" [3] "NE2_50M_SR/NE2_50M_SR.tif" "NE2_50M_SR/Read_me.txt" ``` so we can do ```R vapour::vapour_raster_info("/vsizip//vsicurl/https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/50m/raster/NE2_50M_SR.zip/NE2_50M_SR/NE2_50M_SR.tif") $geotransform [1] -180.00000000 0.03333333 0.00000000 90.00000000 0.00000000 [6] -0.03333333 $dimension [1]...

I tried a minimal network with 5 edges joined at two nodes:  ```R edges

feature request: snap to vertex

5

My first enhancement request is for drawing/edit snap-mode, so that we can align segment-based shapes to existing vertices. Snap is illustrated here: http://makinacorpus.github.io/Leaflet.Snap/ Because we can upload point layers already...

[feature request] point options

11

This became a clear need when I digitized the nodes in this image: https://gist.github.com/mdsumner/449148a78ccea02b19ab1a21bfc5acb3 I really need a point that's not a big icon. I ended up digitizing it "top...

underlying algorithm

I'm interested in apply the underlying Visvalingam algorithm directly to paths, do you know if it's available in R independently of the mapshaper interface? The approach for sf polygons could...

Handle special column classes more elegantly

5

(just some notes for now, @ateucher please assign to me) - can we rejig to do the data frame traverse first, otherwise long-running geom-task fails - use as.Date/as.POSIXct with explicit...

Your call for examples made me realize I need purrr for table-fying the new `sf` classes. Warning, this is not extensively tested, and I only look at polygons below (not...

suggestion: include sinusoidal binning scheme

6

I wonder if you'd be interested to include the binning scheme used by the ocean colour group for L3? This scheme is described here: http://oceancolor.gsfc.nasa.gov/cms/L3Bins.html I've implemented it in simple...

WIP further source options for imagery

I think this is enough to show the potential, it takes a bit of refactoring since so much logic goes into tile-handling atm, but we don't have to bother with...
