hello. excuse-me for my bad English.
i'm new to sharpmap. and i have some question:
1-how can i create selectable line point and polygon?
2- how to create a new toolbar (not built-in one) that create a line?
3- what is Symbolizer and ID? and a brief explain how sharpmap work? and about layers.
Can someone help me? thanks.
