Abstract
The Field data Management System (FMS v. 2.1) is computer software designed for managing, analyzing, and plotting structural geology data. The FMS is composed of two sets of files: one for managing structural geology data on the DOS-PC platform (fmsdos.zip), and another for displaying and generating structural geology themes within the UNIX ARC/INFO GIS environment (fmsunix.tar). The latter set of programs were developed on Sun SPARCstations running ARC/INFO (v. 7.x) and have not been tested on other platforms. Refer to the FMS User’s Guide for a description on program installation and operating procedures.

The FMS is used by the NJGS for managing and analyzing outcrop-based and remotely-sensed structural data and for integrating these data into full-color, quadrangle-scale geologic maps with oriented and annotated structural symbols. The FMS uses geological data that are organized into ASCII data files, usually through keyboard entry. Structural data can then be sorted based on location, stratigraphic unit, and structural variables and graphically plotted in either the map or profile view using a variety of PC-analysis tools. Most of these tools use standard or circular histograms for analyzing the frequency of structural bearing. Statistics are also available for the structural inclination and the quantity of structural data within a sorted data set. Other DOS-PC utilities include data import and export filters that format structural data for use with other commercial geologic analysis software. The FMS does not build GIS coverages of structural symbols – it provides tools for automatically plotting oriented structural geology symbols on ARCPLOT map compositions. Plot files It also can be used for generating GIS themes for the structural bearing or apparent inclination of structures such as fracture-traces.
