Calculate Terrain Color Map
Calculates a color for each point on the surface using a direct elevation-to-color mapping.
height_shade(
heightmap,
texture = (grDevices::colorRampPalette(c("#6AA85B", "#D9CC9A", "#FFFFFF")))(256),
range = NULL,
keep_user_par = TRUE
)heightmap |
A two-dimensional matrix, where each entry in the matrix is the elevation at that point. |
texture |
Default 'terrain.colors(256)'. A color palette for the plot. |
range |
Default 'NULL', the full range of the heightmap. A length-2 vector specifying the maximum and minimum values to map the color palette to. |
keep_user_par |
Default ‘TRUE'. Whether to keep the user’s 'par()' settings. Set to 'FALSE' if you want to set up a multi-pane plot (e.g. set 'par(mfrow)'). |
RGB array of hillshaded texture mappings.
#Create a direct mapping of elevation to color: montereybay %>% height_shade() %>% plot_map() #Add a shadow: montereybay %>% height_shade() %>% add_shadow(ray_shade(montereybay,zscale=50),0.3) %>% plot_map() #Change the palette: montereybay %>% height_shade(texture = topo.colors(256)) %>% add_shadow(ray_shade(montereybay,zscale=50),0.3) %>% plot_map() #Really change the palette: montereybay %>% height_shade(texture = rainbow(256)) %>% add_shadow(ray_shade(montereybay,zscale=50),0.3) %>% plot_map()
