Extract Raster Masks from geosam Object — sam_as_raster • geosam

Converts detection masks from a geosam object to a terra SpatRaster.

Usage

sam_as_raster(x, combined = FALSE)

Arguments

x: A geosam object from sam_detect() or sam_explore().
combined: If TRUE, combine all masks into a single layer (union). If FALSE (default), return a multi-layer raster with one layer per detection.

Value

A terra SpatRaster with mask values (1 = detected, 0 = background). Returns NULL if no masks.

Examples

if (FALSE) { # \dontrun{
result <- sam_detect(image = "satellite.tif", text = "building")
mask_raster <- sam_as_raster(result, combined = TRUE)
terra::plot(mask_raster)
} # }
