•PEDITOR was originally written in the 1970's, and has been updated and maintained since by NASS. It was developed during the early 70’s using Purdue University’s LARSYS system as a basis for further development.  NASS and the University of Illinois Center for Advanced Computing developed a customized program called EDITOR.  It was ported to other computer platforms by NASS and the name modified to PEDITOR.
•NASS has supported PEDITOR throughout the LACIE and AgRISTARS programs and continues to today, as PEDITOR was updated and modified to run on the latest desktop platforms utilizing some of the original algorithms from the LARSYS project.
•PEDITOR is written mainly in DELPHI (Visual PASCAL) with a few subroutines remaining in FORTRAN.  PEDITOR was written to run on a variety of computers, including; Cray supercomputer, IBM mainframe, Vax mini, UNIX workstations, and now PC microcomputers.  PEDITOR was ported to the desktop once PC's were capable of handling the processing requirements.
•The clustering/classification/mosaicking/estimation programs only run on the XP platform using "Batch" type processing features.  “Expert" components or "rules of thumb" have been built into PEDITOR to expedite processing of repetitious tasks.  PEDITOR is now capable of importing/exporting published commercial vendor formats, such as ESRI’s shapefile and Erdas Imagine .lan and .gis formats.
•RSP was developed in the early 1990’s to manage the ground truth data collection effort, tracking segment production, minimize digitizing errors, and provide an expert like interface for the end user.  RSP was originally developed under FoxPro and migrated to Visual as the industry moved in that direction.
