Landsat-8 OLI image pixels for developing water mapping algorithms

This dataset contains 153140 Landsat-8 OLI pixels. The pixels were collected from 180 subsite images (900 by 900 m) in 22 Landsat-8 OLI imageries that covering various water-land environments around the world. Each pixel is represented as a row of data with the attributes described here.

DATE - The date of the Landsat 8 OLI image acquisition as YYYYMMDD.

PATH/ROW - The Worldwide Reference System path and row of the Landsat image.

SR - Spatial reference read from ArcGIS 10.5

CORX - x-coordinate of pixel center in the SR system

CORY - y-coordinate of pixel center in the SR system

WT.PCT - An integer value of the percentage area of the pixel that is covered by water.

PIX.TYPE - Defined a pixel is water (1) or non-water (0)

CLASS - The dominant land type contained in pixel. WT = water, VL = vegetated land, BL = built-up land, and SL = shadowed land

BAND1, 2, 3, 4, 5, 6, 7 - Band surface reflectance.

NDWI, MNDWI, AWEI0, AWEI1, WI2015 - The five water indices calculated with the algorithms listed below.
NDWI = (ρb3-ρb5) / (ρb3+ρb5)
MNDWI = (ρb3-ρb6) / (ρb3+ρb6)
AWEI0 = 4(ρb3-ρb6)-0.25ρb5-2.75ρb7
AWEI1 = ρb2+2.5ρb3-1.5(ρb5+ρb6)-0.25ρb7
WI2015 = 1.7204+171ρb3+3ρb4-70ρb5-45ρb6-71ρb7
where ρ is surface reflectance and b1, b2, …, b7 are band numbers of Landsat-8 OLI images.
