mt_bbox function

Converts lower-left sinusoidal coordinates to lat-lon sf bounding box

Converts lower-left sinusoidal coordinates to lat-lon sf bounding box

mt_bbox(xllcorner, yllcorner, cellsize, nrows, ncols, transform = TRUE)

Arguments

  • xllcorner: lower left x coordinate as provided by mt_subset
  • yllcorner: lower left y coordinate as provided by mt_subset
  • cellsize: cell size provided by mt_subset
  • nrows: cell size provided by mt_subset
  • ncols: cell size provided by mt_subset
  • transform: transform the bounding box from sin to lat long coordinates, TRUE or FALSE (default = TRUE)

Examples

# Download some test data subset <- mt_subset(product = "MOD11A2", lat = 40, lon = -110, band = "LST_Day_1km", start = "2004-01-01", end = "2004-03-31", progress = FALSE) # convert sinusoidal to lat / lon lat_lon <- sin_to_ll(subset$xllcorner, subset$yllcorner) # bind with the original dataframe subset <- cbind(subset, lat_lon) # convert to bounding box bb <- apply(subset, 1, function(x){ mt_bbox(xllcorner = x['xllcorner'], yllcorner = x['yllcorner'], cellsize = x['cellsize'], nrows = x['nrows'], ncols = x['ncols']) }) head(bb)
