Tutorial: How to Create Custom Symbols (SVG Marker) for QGIS
QGIS provides many pictorial symbols stored in *.svg format with several classifications, including accommodation, arrows, emergency, food, health, money, religion, shopping, transport, service, sports, amenities, landmarks, entertainment, tourist, and wind roses. All svg files are stored in the QGIS symbol directory (Settings - Options - System - SVG path).
