sponge | R Documentation |

This dataset contains 77 samples of 8 variables including longitude (easting), latitude (northing), sponge, topographic position index (tpi3), variance of backscatter (var7), entropy (entro7), backscatter at incidence angle 11 degree (bs11), and backscatter at incidence angle 34 degree (bs34).

data("sponge")

A data frame with 77 observations on the following 8 variables.

`easting`

a numeric vector, m

`northing`

a numeric vector, m

`sponge`

a numeric vector, no unit

`tpi3`

a numeric vector, no unit

`var7`

a numeric vector, dB^2

`entro7`

a numeric vector, no unit

`bs11`

a numeric vector, dB

`bs34`

a numeric vector, dB

For details, please see the source. This dataset was published as an appendix of the paper listed in the source. Where the long and lat were replaced with easting and northing for prediction purpose.
