sl_sub <- sl[0:10000,]

#Get data from primary channel and plot it
sl_primary <- sonar_image(sl_sub, channel = "Primary")

sonar_show_image(sl_primary)

sl_sidescan <- sonar_image(sl_sub, channel = "Sidescan")

sonar_show_image(sl_sidescan)

Georeferencing data:

#Georefence sonar sidescan data
sl_geo <- sonar_sidescan_geo(sl_sub)
