Generate vector tiles for rnet_bicycle

[layik]

Hi all. Just looking at https://github.com/saferactive/saferactive/blob/master/code/rasters-rnet.R but cannot run

saferactive/code/rasters-rnet.R

Line 9 in d227ab2

u = "https://github.com/saferactive/saferactive/releases/download/0.1.1/rnet_national_sf_27700.Rds"

Can you point me to where rnet_national_sf_27700.Rds is or which script was used to generate it to so I can source or regenerate it?

Thanks

Just looking at this @layik, solution soon.

Just updating the data with this:

Rscript -e 'piggyback::pb_upload("rnet_national_sf_27700.Rds")'

[Robinlovelace]

Strange thing: I thought I already updated it. Never mind.

[Robinlovelace]

I think this code should now run. Please test and let me know @layik:

saferactive/code/rasters-rnet.R

Lines 2 to 13 in d227ab2

	library(sf)
	library(tidyverse)
	library(raster)
	# get osm cleaning code:
	remotes::install_github("saferactive/trafficalmr")
	if(!file.exists("rnet_national_sf_27700.Rds")){
	u = "https://github.com/saferactive/saferactive/releases/download/0.1.1/rnet_national_sf_27700.Rds"
	f = basename(u)
	download.file(u, f, mode = "wb")
	}
	rnet_national_sf_27700 = readRDS("rnet_national_sf_27700.Rds")

Thanks @Robinlovelace, works of course. I will tippercanoe it and add the code in same/different file.

[Robinlovelace]

Awesome, thanks @layik !

Generating heatmap using the vector tiles is possible, though mastering it needs time @mem48.

Both raster + vector tiles generated in the release (as zip) are "zoom dependent" and have zoom level limit. Refer to their meta files and if you want to use them just be aware or generate your own raster/vector tiles. For the rasters I used the interactive Python tool gdal2tiles.py straight from the .tiff which is also in the release.
