This module enables the user to display or plot raw data, updated polygons, or filled polygons. Programs that create or edit various input files that are needed by these display programs are also included in this module. The Display Maps choices appear below:
For topography and pit maps, there is only one program that can be used to display maps: Plot Raw Geology or Topo Maps. For geologic data, there are three different forms that the data can be in and, consequently, there are three choices for displaying geologic data.
The program to plot raw geology, pit designs, or topo maps is used to display the raw digitized geology data. The program to plot updated geology is used to plot the updated line segments that are labelled left and right with the area name that exists on each side of the segment. Polygon fill displays of the updated geology are made with the plot filled polygons program.
This menu choice enables the user to invoke commands and run external programs without exiting PolyMap. Refer to section 1.1 for details.
This menu choice allows the user to display plots of either digitized geology, pit designs, or digitized topography.
This program can be used to display the contents of any PolyMap raw data file. Selections for display are made on the basis of location, layer, and any special controls the user chooses to implement.
After starting the program, the user is first required to select the appropriate answer set. Then, the first input screen is presented which includes map choice, grid option, plot extent, and color choices.
The first input field is for the answer set name. The map to display is chosen from a drop down menu. Both local and global grids can be plotted for plan view maps. The user should refer to MicroMODEL documentation for information on local and global grids.
The plot file root name is entered in the second field.
For plan view maps, the plot limits are set by selecting starting and ending rows and columns to display. For sections, the left and right edge coordinates are entered, as well as the top and bottom elevation.
For plan maps, the user also has control over what type of local grid is displayed, and whether or not a global grid is displayed.
Pen colors for grids are also selected in this screen.
The second screen contains input information for controlling display colors and labeling. The user should refer to the program help for more information.
The final input screen is for entering miscellaneous plotting parameters, including elevation line options for section plots.
The label control map is a separate map that is used in conjunction with the raw data display program. The label control map is an entirely separate map from the map that is actually being plotted. It must be created using PolyMap interactive pit digitizing program. This label control feature was specifically designed for use in displaying pit maps and topography maps.
Two types of labelling are possible; in-line and below line. In-line labelling is generally used for topographic contours, while below line labelling is normally used on pit access roads and ramps.
The labelling control map consists of one or more traces that are digitized so that, if the traces are overlaid onto the map being plotted, the traces will intersect one or more of the contour lines on that map.
The way in which each labelling control trace interacts with the map being plotted is governed by the name assigned to the labelling control trace. Two separate items of information are placed within the name of the control trace. These items are encoded as follows:
Character 1 = labeling type code 1 = in-line labeling 2 = downhill labeling Characters 5-8 = optional labeling interval
Examples of different label names, and the type of labelling they would create, are shown below:
12345678 Example 1: 2 This label name would create downhill labels for each contour on the original map that this label control trace intercepts. 12345678 Example 2: 1 100 This label name would create in-line labels for each contour on the original map that this label control trace intercepts, but only if that contour is evenly divisible by 100.
Note that there is a choice in the pulldown Polyline menu that allows the user to set the labeling parameters. Select "Set Polyline Name for Label Control" and enter your choice from the dialog box provided.
If the trace name on the map being plotted matches one of the names in the label exclusion list, then that particular trace will not be labelled, even though a label control line intersects with that trace.
It is always assumed that the traces being labelled by the label control file have been digitized or created following the convention that the trace runs in a direction with downhill to the right.
In-line labels begin at the point of intersection between the label control trace and the contour and are plotted from there towards the end of the contour. Downhill labels are centered at the intersection point and are plotted on the downhill side of the contour.
Label exclusion is normally used to control the plotting of waste dump outlines, roads, cut/fill lines, building locations, etc. These type of lines do not normally require a label, but might need to be plotted as dashed lines. The pen number (color) used when plotting these excluded traces is still governed by the pen control options.
For each trace type, the user enters the line label. The remaining four fields for each trace are for optionally changing the line drawn for the excluded trace from a solid line to a dashed pattern. For solid lines, all four fields are set to 0.0 units. For simple dash patterns, the user enters one dash length in the column labeled "Dash-1", and one space length in the column labeled "Space-1."
For more a more complex, alternating, dash pattern, the user enters a second dash length in the column labelled "Dash-2", and a second space length in the column labeled "Space-2."
For example if the four dash control fields for a given trace are entered as 50, 10, 25, 10, then that trace will be plotted with a dash pattern that consists of alternating 50 unit and 25 unit dash lengths, separated by 10 units between each of the dashes.
This option is used to display the contents of any updated PolyMap map, or set of maps as defined by an include set. Selections for display are made on the basis of location and layer.
After starting this program, the user is asked to select the appropriate answer set. Following this, the user is presented with the first input screen.
The first input field is for entering the answer set name. The map to display is chosen using the pull down menu. Optionally, the user can choose to display the entire set of maps contained in a particular include set by checking "Display All Maps in Include Set". The specific include set is selected via the adjacent pull down menu.<\P>
Plot limits are controlled by row and column numbers for plan view plots. For sections, the plot limits are defined by the section edge coordinates and the bottom and top elevation. Local and global grids can be plotted for plan view maps. Various pen colors are selected on this screen.
The second input screen controls how the polylines will be displayed. Two radio buttons allow for selecting between NOT displaying any names, or displaying the right and left hand area names adjacent to the polylines.
The user specifies which include set (see section 1.6) of maps will have their intercepts drawn via a drop down menu. Intercepts for maps defined by this include set will be drawn onto the map displayed by this program. If zero (0) is selected, then no intercepts will be drawn. If a non-zero value for include set is entered, then the user must specify intercept plotting parameters for each label type (area) on a subsequent screen.
A check box "Display Trace (Line) Pierce Points controls whether or not to display pierce points from the maps defined in the include set. Pierce point display options are entered in a subsequent screen.
If the user requires special shading, then the number of shading combinations is selected. If selected, then the user must enter details of each shading combination on a subsequent screen.
The color buttons in the Pen Colors for Control by Layer group box control the pen number (color) to use for traces belonging to each of the layers that have been defined for the PolyMap project. To suppress the display of a layer, select the 0 (do not plot) color.
In the third input screen, the character size for plotting traces and for plotting grid labels are entered. Also, if the map being displayed is a section map, then parameters for controlling the display of elevation grid lines are entered.
Following the third screen are optional input screens for intercept plotting, pierce point plotting, and shading.
The user selects RUN to run the program, EDIT to change input, or QUIT to quit the program. Following this, the user is prompted for title block information. Refer to MicroMODEL documentation for instructions on title block display.
If the user elects to continue with the program run, then a plot file is created, and the user can then preview the plot on screen. The plot can also be output in HP750C plotter format, or to AutoCAD DXF format.
This choice allows the user to display filled polygons from an updated geology map. Its main function is in quickly checking section and plan maps of geology to see that they have been correctly digitized, and that no errors occurred in the update process.
After selecting this program, the user is requested to select an answer set. The first input screen is then displayed, which allows the user to select which maps to display, what control file to use, and control the plotting of the map title. The user can also override the default map limits, if desired.
The first input field is for the answer set name. The must then select one or more maps to display from the listing shown. If multiple maps are selected, then they are written to the plot file as separate plots within a single plot file. Thus, the "Skip Map" option comes into play. Refer to the MicroMODEL documentation for details.
The layer to display is chosen from the drop down list in the "Select Layer to Display" group box. You can only display filled polygons from a single layer.
The map name can automatically be displayed at either the top of the map, or at the bottom of the map. Or, to eliminate display of the map name, select "No Display." If display at the top or bottom is chosen, then the pen color to use and the text size as a percent of map height must be specified. Be sure to use a text color that is different than any of the possible colors that will be used to display filled areas.
The "Override Limits" check box should be selected if the user wants to override the default map limits and use relative offset limits that are entered in the last four input fields. Normally, the default map limits are used so that the full map displays on the video screen. In some cases, however, the user may desire to override the default limits to display only a portion of the map. Leave this check box unselected to use default limits.
If default limits are overriden, then the relative minimum and maximum limits for the map are entered in the last four input fields. These relative limits are the distance measured from the original lower lefthand corner of the map in user units. For example, to display the first 200 units of map horizontally and the first 100 units of map vertically, the relative horizontal limits are set to 0 and 200; the relative vertical limits are set to 0 and 100.
After entering all responses, the user should continue on to the next screen, and select the pen color to use for each of the area names that are part of the selected layer. Following that screen are one or more screens where the pen color of traces (lines) are chosen. You may set any of these colors to zero to suppress the display of that particular area or trace.
An excellent use for these files is to display them as background plot files with the "Digitize Geology" program. Be sure to check "Auto Run PFILL after digitizing geology, and also Auto Update after digitizing geology to make better use of this feature.
