A detailed guide on creating a user-defined basemap

Description:
How to create a new basemap after the default_map and default_appearance have
already been created?

Solution:
Every Map contains a Map Appearance. If there are no changes to be made to the
Map Appearance, then begin with the instructions for creating a map.
 
Map Appearance
--------------
1. From the basemap go to File > New > Map appearance...

2. Enter in a new name and description for the Map appearance in the windows at
the top. Select the Create button. Any further changes made to the new Map
appearance can be saved using the Update button.
 
3. To make any changes to the organization of the layers, select the
Add/delete/order appearance layers... button.  Anything from the 'Layers
available' list can be moved to the 'Layers selected' list by highlighting the
layer and selecting the Top or Bottom button. They can also be moved by clicking
at the desired insertion point on the 'Layers selected' list. Layers can be
removed from the selected list by highlighting them. The order that the layers
are posted on the basemap is determined by the 'Layers selected' list. The layer
at the top is the uppermost layer on the basemap. Select the OK button to exit
this window. The changes made in this window will be reflected in the
'Appearance layers' window but will not be saved to the current appearance file
until the Update button is selected.
 
*Note: Removing a layer from the display is over-ridden by the Post function.
ex. If you remove the Horizons layer from the Layers selected list then go to
Post > Interpretation > Horizon and post one or more horizons, the Horizons
layer is added to this list.

4. Under the Appearance layers window, layers may be selected and the
characteristics of that layer will be displayed in the Layer rendering window.
ex. If Paths_polygon was highlighted in the Appearance layers window, the line
width could be changed from 'Thin' to 'Very Fat' by toggling the Line width
button in the Layer rendering window to the thickest line.

*Note: If you change an attribute for rendering that is not applicable to the
selected layer, no change occurs.

Hidden = layer is still present but not visible. *Note: This is also over-ridden
by Post function.
Searchable = layer can be selected with the mouse, perhaps for editing.
If this attribute is turned off for a specific layer, you can see the layer but
you cannot select it.
Fg = foreground color
Bg = background color
Text size = controls the type size of the text
Symbol size = controls the size of the symbol
Line width = thickness of the lines
Line style = the style of line to display
 
*Note: The five line styles below the solid line use both Fg and Bg colors. The
five styles above the solid line use only Fg colors.

5. In the Canvas render window the background and highlight colors can be
changed. When changing the background color a warning message will appear
'Background color change may affect visibility of map objects.' Be careful to
pick a color that does not obscure other settings. The three Canvas highlight
colors have different functions. The first color(from left to right) is used by
Basemap to highlight items while moving the mouse across the map and to indicate
that a highlighted item has been selected. The second color represents the
portion of the line that is displayed in the Seismic window. The third color is
used when more than one seismic panels are displayed in the Seismic window. This
color indicates the portion of the line(s) displaying in the Seismic window that
is (are) not active. At the bottom left of each seismic panel the first box from
the left will contain a check mark if the seismic panel is active.

6. Select the Apply button to save the changes and Cancel to exit the window.

Map
---
1. Select from Basemap File > New > Map... and enter in the name and description
for the new map.
  
2. Under the Content window, data can be moved between the Available and
Selected lists by selecting the data. The Select borehole data.., Manage
borehole sets..., Manage borehole appearance can be used to change borehole
content or display.
 
3. In the Map projection window the default projection for the project is
listed. To change the projection select the Define projection... button and
choose the desired listing. Projections are defined in the GeoFrame Project
Manager > Edit.

4. The Angles button is used to display the latitude/longitude around the border
of the map in either Degrees, minutes, seconds, or Decimal degrees. (The Decimal
degrees does not work in GeoFrame 3.1.4 and prior releases.)
 
5. The extent of map area can be changed to Border around all data, Border
around all surveys, Border around all boreholes, Current window limits, or
Corner latitude/longitude.

6. Select the desired Appearance file to use and select OK. Selecting the OK
saves the current parameters to the selected map name, closes the Create Map
dialog box, and displays the map. The Default map is used to restore the
selected parameters, including content, to those of the default map.
