Evaluation of Multiple Classifier Systems for Landslide Identification in LANDSAT Thematic Mapper (TM) Images

  • Luiz Augusto Manfré,
  • Rodrigo Affonso De Albuquerque Nóbrega and
  • José Alberto Quintanilha

Landslide scar location is fundamental for the risk management process, e.g., it allows mitigation of these areas, decreasing the associated hazards for the population. Remote sensing data usage is an essential tool for landslide identification, mapp...

A Subdivision Method to Unify the Existing Latitude and Longitude Grids

  • Chengqi Cheng,
  • Xiaochong Tong,
  • Bo Chen and
  • Weixin Zhai

As research on large regions of earth progresses, many geographical subdivision grids have been established for various spatial applications by different industries and disciplines. However, there is no clear relationship between the different grids...

A Combination of Stop-and-Go and Electro-Tricycle Laser Scanning Systems for Rural Cadastral Surveys

  • Liang Zhong,
  • Pengfei Liu,
  • Liuzhao Wang,
  • Zhanying Wei,
  • Haiyan Guan and
  • Yongtao Yu

Over the past decade, land-based laser scanning technologies have been actively studied and implemented, in response to the need for detailed three-dimensional (3D) data about our rural and urban environment for topographic mapping, cadastral mapping...

Assessing Patient bypass Behavior Using Taxi Trip Origin–Destination (OD) Data

  • Gege Yang,
  • Ci Song,
  • Hua Shu,
  • Jia Zhang,
  • Tao Pei and
  • Chenghu Zhou

Many patients prefer to use the best hospitals even if there are one or more other hospitals closer to their homes; this behavior is called “hospital bypass behavior”. Because this behavior can be problematic in urban areas, it is important that it b...
