1-meter resolution land cover classification
This layer provides automatically-derived land cover classifications of the Puget Sound trough below 1,500 meters elevation. A six-class 1-meter land cover layer was developed using the Naïve Bayes classifier (Google, 2019) and trained using a 10-meter land cover product from NOAA Coastal Change Analysis Program (C-CAP) (NOAA C-CAP, 2018a). Other data combined with this analysis includes water body and river polygons (Washington Department of Natural Resources), shoreline polygons (Esri), over-water structure polygons (Washington Department of Natural Resources), road polygons buffered from centerlines (U.S. Census Bureau, 2016), and building rooftops polygons (Microsoft, 2019). Accuracy was validated accuracy with an observed land cover point dataset from the Washington Department of Fish & Wildlife (Pierce, Jr., 2015).
Layer Access in Earth Engine
// Import the layer data dictionary
var data = require('users/stormwaterheatmap/apps:data/public')
// To view data dictionary, print to the console:
//Get this layer from the layer data dictionary:
var layer_name = data.rasters["Land Cover"]
Individual objects contain all the info used in the stormwater heatmap. To add it to the map, add the layer object.
var display_image = layer_name.layer
To get the raw image data for analysis, access the
var raw_image = layer_name.layer.eeObject
