Data for "A progressive and combined building simplification approach with local structure classification and backtracking strategy"

It is a data for paper named "A progressive and combined building simplification approach with local structure classification and backtracking strategy". Three datasets are provided. One is the original data, which is collected from an open data product named OS Open Map –Local and provided by Ordnance Survey. Another two datasets are buildings which are simplified based on the original dataset into scales of 1: 25, 000 and 1: 50, 000. The simplification approach are proposed in the paper "A progressive and combined building simplification approach with local structure classification and backtracking strategy" .

本数据集为论文《结合局部结构分类与回溯策略的渐进式组合建筑简化方法》("A progressive and combined building simplification approach with local structure classification and backtracking strategy")的配套数据集。本次共提供三类数据集：其一为原始数据集，采集自英国地形测量局(Ordnance Survey)提供的开放数据产品OS开放地图——本地版(OS Open Map – Local)；另外两类为基于该原始数据集简化得到的建筑数据集，比例尺分别为1:25000与1:50000。本次所用的建筑简化方法即出自该同名论文。
