I thought this would be quite easy to implement, but apparently terra
reprojects the data differently and changes the resolution and dimension of the data set (raster
doesnt change those).
Using the plainview::poppendorf
dataset, the original Raster looks like this (SpatRaster has the same dimensions and resolution):
class : RasterBrick
dimensions : 167, 166, 27722, 5 (nrow, ncol, ncell, nlayers)
resolution : 30, 30 (x, y)
extent : 655905, 660885, 5508915, 5513925 (xmin, xmax, ymin, ymax)
crs : +proj=utm +zone=32 +datum=WGS84 +units=m +no_defs +ellps=WGS84 +towgs84=0,0,0
source : memory
names : B001n, B002n, B003n, B004n, B005n
min values : 8921, 7983, 6894, 6154, 5954
max values : 14123, 14060, 14390, 15080, 24972
but after leaflet is reprojecting a SpatRaster
, the data looks like this
class : SpatRaster
dimensions : 172, 171, 1 (nrow, ncol, nlyr)
resolution : 46.39897, 46.39897 (x, y)
extent : 1242617, 1250552, 6396416, 6404396 (xmin, xmax, ymin, ymax)
coord. ref. : WGS 84 / Pseudo-Mercator
source(s) : memory
name : B004n
min value : 6166.153
and we get the following error which fails here as the length of raster values and colors doesnt match anymore. :
Error in dim(tileData) <- c(4, ncol(x), nrow(x)) : dims [product 117648] do not match the length of object [110888]
raster
is being superseded by terra.. but it would work.addRasterRGB
before creating the colors. Then their length should match.
I am testing as I am writing this issue. Reprojecting first also seems to be an easy fix. I will push a PR in a bit.
Hi everyone,
The raster package announced it has been superseded by the "terra" package. https://cran.r-project.org/web/packages/raster/index.html
Could addRasterRGB function support object in terra package in future? Such as SpatRaster created by
terra::rast()
.Thank you.
