gt_mosaic: Mosaic rasters with different origins and resolutions

Description

The raster::mosaic() function requires rasters to have the same origin and resolution. However, when producing multiple rasters to query traffic data across a large study area, the rasters will not have the same origins and may not have the same resolutions (in cases where rasters at different latitudes are queried). gt_mosaic() allows for mosaicing rasters with different origins and resolutions.

Usage

gt_mosaic(r_list)

Value

Returns a raster.

Arguments

r_list

List of rasters

Examples

r1 <- raster::raster(ncol=10, nrow=10, xmn = -10, xmx = 1,  ymn = -10, ymx = 1)
r2 <- raster::raster(ncol=10, nrow=10, xmn = 0,   xmx = 10, ymn = 0,   ymx = 10)
r3 <- raster::raster(ncol=10, nrow=10, xmn = 9,   xmx = 20, ymn = 9,   ymx = 20)

r123 <- list(r1, r2, r3)

r <- gt_mosaic(r123)
