Many ArcInfo users operate in agencies and organizations which use both ArcInfo and Intergraph's MGE. It has not been possible until now to easily accommodate the need to share data between these two popular GIS systems. Redlands Software has developed products to meet this need. Arc2Mge directly translates an uncompressed ArcInfo Export file into MGE. Mge2Arc directly translates MGE data into uncompressed ArcInfo Export files. ArcInfo users attending this presentation will learn how they can accommodate the requirements of their MGE colleagues, and how they can import data from MGE projects. Emphasis will be placed on defining the problems of sharing data between this two systems, and the technical solutions provided by the software.
The Tri-Service Spatial Data Standards (TSSDSs) have been designed and implemented by the Tri-Service CADD/GIS Center at the U. S. Army Corps of Engineers' Waterway's Experiment Station, in Vicksburg, Mississippi. The TSSDS's were developed as a comprehensive master and environmental planning data model for Air Force, Army, and Navy installations, as well as Corps of Engineers' civil works projects. The standards address data content, classification, format, and presentation of geospatial entities depicted in large scale mapping (primarily, 1 inch = 400 feet (1:4800) to 1 inch = 50 feet (1:600)). The TSSDS development program has defined a generic data model, based on the Spatial Data Transfer Standards (SDTS - FIPS 173), that can be implemented on multiple CADD/GIS platforms. The need for standardization arise from the CADD/GIS community's need to share data such as drawings, attribute information, and symbology across CADD/GIS platforms. The TSSDS provide a variety of standardized symbology to be used across multiple platforms. These symbols were designed and created in MicroStation and stored in a variety of cell libraries corresponding to TSSDS entity classes (themes). These symbols were converted from MicroStation to AutoCAD and ArcInfo formats. The symbols had to be customized to meet the requirement of each platform. The conversion of symbology from one platform to another is a subject that has not been widely addressed by the CADD/GIS community. The intent of this paper is to provide guidance to the CADD/GIS community on the conversion of symbology from a MicroStation cell library format to an ArcInfo markerset format.
