Abstract
Three-dimensional landform data are generated by laser profiler (LP), mobile mapping system (MMS), laser scanner (LS), and camera on UAV (Unmanned Aerial Vehicle). There are no standards for representing and drawing three-dimensional landform data. In this paper, the first version of three-dimensional landform modeling guideline was proposed. It targets the landform and standardizes a common specification of landform in civil infrastructure domain. It standardizes the notation of view, and proposes to define the contents of conformance class, level of detail, management information, annotation, used point, line, surface and solid, and features. The three-dimensional data measured by LP, MMS, LS and camera on UAV were displayed on Cloud Compare for discussing the view of landform. The results were classified by density of point cloud. The guideline is proposed the menu of view by density of point cloud.
