City Generator

A screen shot of demo

Demo: https://knt5.github.io/demo/city-generator/

  • This is a tech demo to predict height of buildings in real time on web browser and generate 3D city.
  • The height prediction is based on elevation data (DSM) recoded by Advanced Land Observing Satellite "DAICHI" (ALOS) of JAXA.
  • The demo also uses building peripheral lines and elevation data without height of buildings (DEM) by GSI (Geospatial Information Authority of Japan).
  • GSI's building peripheral lines were converted to GeoJSON from JPGIS GML by jpgis-convert.

A summary image of descriptions

Japanese:

  • ビルの高さ推定をブラウザ上でリアルタイムに行い 3D 市街地を構築するデモです。
  • JAXA の陸域観測技術衛星「だいち」(ALOS) による標高データ(DSM)をベースに高さ推定を行っています。
  • この他に国土地理院の建物外周線データと、ビル高さなし標高データ(DEM)を使用しています。
  • 拙作 jpgis-convert を使って国土地理院の建築物外周線データを JPGIS GML から GeoJSON に変換しています。
