2.0 PolyMap SYSTEM OVERVIEW

PolyMap is comprised of four different modules which logically group the system into different functions. The main modules within PolyMap are:

The following text contains a brief overview of each PolyMap module. A more comprehensive discussion of each program can be found in the PolyMap Program Documentation, Volume II, Sections 1.0 through 4.0.

2.1 System Setup and Map File Manipulation Overview

The System Setup and Map File Manipulation Module is invoked initially to set project limits, define layers, and create maps. Later, it is used for listing or changing include sets, modifying map parameters, and displaying map file information.

Before any other task is performed, the Project Information File must be established. This file contains information that each program will need for execution such as model origin, rotation, block size, and model units (feet/meters). Geology layers, polyline names, and area names are also defined with this program. It is mandatory to have run the Project Information Program before any other programs can be run.

The remaining programs in this module enable the user to create maps, and manipulate or list map file information. Three programs are used for digitizer setup.

2.2 Map Editing and Digitizing Overview

The Map Editing and Digitizing Module contains a series of programs that enable the user to digitize and/or edit maps interactively using several different programs. One program is specifically geared towards digitizing geologic zoning information, while the other is tailored for the design of open pits. These two programs are very similar, with the only main difference being the way in which layering is applied. A manual editor is also available for making simple changes such as single or global name changes for traces or locations, or deleting map features.

In addition, there are several utility programs for filtering extraneous points, adding topographic profiles, joining traces with common endpoints, and for meshing pit designs with original topography. A pair of programs allows the user to define a polygon that is used as a "cookie cutter" to include or exclude information within that polygon.

2.3 Display Maps Overview

This module allows the user to display map information in one of three ways. First, the raw digitized data can be displayed for either geologic maps, or topo/pit maps. Second, updated geologic maps can be displayed, optionally showing intercepts from other maps. Finally, filled polygons can be displayed depicting different zones of the geologic information.

2.4 Import/Export Overview

This module allows the user to interface between PolyMap and other systems. The user may import from MicroMODEL ASCII files POLY.CNT or POLY.PIT, PolyMap ASCII files, or from other PolyMap (binary) map files. The user may export to either MicroMODEL ASCII files POLY.CNT or POLY.PIT, or to PolyMap ASCII files.

Two programs are included in this module that specifically allow the user to interface to the MicroMODEL POLY.RKS and POLY.RKP files. These files are used for creating or updating the MicroMODEL 3-D rock file in section or in plan, respectively.
