Description
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 with an observed land cover point dataset from the Washington Department of Fish & Wildlife (Pierce, Jr., 2015).
Layer Access in Earth Engine
The JavaScript below loads this layer in the Earth Engine Code Editor. An Earth Engine account is required. The "open" links above show each asset's details in the Code Editor.
// Import the layer data dictionary
var data = require('users/stormwaterheatmap/apps:data/public')
// To view data dictionary, print to the console:
print('Data:', data)
// Get this layer from the layer data dictionary:
var layer_name = data.rasters["Land Cover"]
// Add the styled layer to the map:
Map.addLayer(layer_name.layer)
// Raw image for analysis:
var raw_image = layer_name.layer.eeObject
Map.addLayer(raw_image, {}, 'Land Cover')
