Custom symbols

Mike,
I use a variety of National Park Service symbols as custom points in my project. I read in the help file that vector symbols imported through the simple ascii process will scale better than custom icons from images. I'm not sure I understand the format of the text file though. Can the GM_SYM functionality be used to import the attached graphic and therefore provide a better appearance? Thanks!

Ray,
You could use the GM_SYM functionality to describe your shape as a vector, but it would take quite a few vertices. It looks like you would have 5 separate filled area definitions, one for the outer black rectangle, then 4 white filled areas for the 4 separate shapes defining the symbol.
Here is a sample showing the horizontal bedding symbol definition from Global Mapper:
PEN_STYLE=SOLID
PEN_COLOR=RGB(0,0,0)
PEN_WIDTH=1
-7,0
7,0
PEN_STYLE=SOLID
PEN_COLOR=RGB(0,0,0)
PEN_WIDTH=1
3.000,0.000
2.942,0.585
2.772,1.148
2.494,1.667
2.121,2.121
1.667,2.494
1.148,2.772
0.585,2.942

Note that this is defined as two lines. For areas you would add CLOSED=YES to the parameter list at the type of each set of coordinates, as well as a fill color via FILL_COLOR=RGB(255,255,255) [this is for white, use 0,0,0 for black].
Let me know if I can be of further assistance.
Thanks,
Mike
