How to Visualize and Analyze Building Heights with Google Earth Engine

[@surbhat]

Nice tutorial. how to export building footprint data with height?

[@techhive.2023]

// Load a building footprint dataset (example: Microsoft or OSM via GEE)
var buildingFootprints = ee.FeatureCollection("TIGER/2016/Buildings");
// Load DSM and DTM (example using Copernicus)
var dsm = ee.Image("COPERNICUS/DEM/GLO30");
var dtm = ee.Image("USGS/NED");
// Calculate building height (DSM - DTM)
var buildingHeight = dsm.subtract(dtm).rename('height');
// Add height to building footprints
var buildingsWithHeight = buildingFootprints.map(function(feature) {
var height = buildingHeight.reduceRegion({
reducer: ee.Reducer.mean(),
geometry: feature.geometry(),
scale: 30,
}).get('height');
return feature.set('height', height);
});
// Export to a CSV
Export.table.toDrive({
collection: buildingsWithHeight,
description: "Building_Height_Export",
fileFormat: "CSV"
});

@@surbhat The error you’re encountering indicates that the asset ID TIGER/2016/Buildings doesn't exist or is inaccessible in Google Earth Engine. This may be due to an incorrect asset ID or the dataset no longer being available.
