Abstract
ABSTRACT PADRAS,PASCO Archaeological DRAwing System, has recently evolved into two directions. The first direction of evolution is utilization of CAD system.The previous mobile type PADRAS system consisted of photo laboratory,portable analytical plotter and X-Y plotter in a microbus.By introducing AutoCAD system into analytical plotter(PADRAS-P3D) and total station surveying system(PADRAS-T3D), we have obtained real time 3D digitizers of a CAD system applied to drawing of archaeological research.Total station surveying system has realized on-line and real-time visualization of an archaeological site on a loptop PC display within the environment of AutoCAD. The second direction is related to connection between CAD system and Data Base system.PADRAS systems attach attributes to graphical features which are compatible to relational data base software(R:BASE PRO).Aiming to digital historical maps or Atlas,PADRAS system,as a whole, evolves out of an approach of Drawing System,Relational Data Base into a construction of Geographic Information System, utilizing new combination among photogrammetry,terrain surveying,CAD system, Data Base systems and Geographic Information System,such as ARC/INFO.
