Global Mapper User's Manual
The Point Styles panel (pictured below) allows the user to configure what symbol will be used to display
points of a given type and at what angle, if any, to rotate the symbol when displaying it on the map. Symbols
can be rotated relative to either the map display (where 0 degrees is always straight up) or relative to true
north, where 0 degrees always points directly to the North Pole. Rotated symbols are good for use in geology
maps and for adding things like north arrows to your maps.
You can also press the Scale button to scale a point symbol to make it larger or smaller. For example, to
double the size of a symbol use a scale of 2.0, whereas to make a symbol half its original size, use a scale of
0.5. You can also specify a symbol size in meters. This will automatically scale the point so that it is always
the specified number of meters tall on the map regardless of zoom level.
The symbol selection list also includes several option at the top of the list to select symbols of common
shapes, like dots, squares, diamonds, etc. with a user-specified size and color.
In addition, the Show Labels for Points of This Type When Present option allows user to turn point labels off
on a type-by-type basis. The Custom Symbols section allows users to create new symbols from their own
bitmap and icon files which they can then use as the symbol to display for a given type.
The New Type button allows the user to create a new point feature type and specify how it should be
displayed. The Edit Type button allows the user to edit point types that were previously created with the New
Type button, and the Delete Type button allows the user to remove point types that were previously created
with the New Type button. With the Attributes button you can specify a set of default attributes and values to
use for new features of this type created using the Digitizer Tool.
If you right click on the list of types, a menu will appear allowing you to save and restore your style settings
using a style file. This provides an easy way to setup a set of styles to use, then restore them at a later date for
use with a particular set of data.
The Custom Symbols section allows you to add new point symbols that will be available for display from your
own files. This includes support for transparent symbols from PNG, ICO, GIF, and 32-bit alpha BMP files, as
well as symbols from JPG images. You can also add vector symbols from EMF, DXF and GM_SYM (Global
Mapper Symbol) files. GM_SYM files are simply ASCII text files that the File->Open Generic ASCII Data
File menu command couuld load, with 0,0 being the center of the symbol and the coordinates specified as
pixels, with X increasing to the right and Y increasing to the top of the symbol. Vector symbols will scale
much more cleanly than symbols based on images.
