The study area is Yokohama City, Japan, an area of 437.4 km\u003csup\u003e2\u003c/sup\u003e. An allometric equation was developed from field measurement data to convert canopy height measured by airborne LiDAR to biomass, and then a map of aboveground biomass (AGB) at 5 m resolution was produced. After validation, the estimation of AGB had a root mean square error of 60.6 Mg ha\u003csup\u003e-1\u003c/sup\u003e and an average relative error of 38.7%. The total forest AGB in Yokohama was estimated as 913,450 Mg.
