Historic　preservation,　adaptive　reuse,　and　sustainable　urban　design　that　considers　the　full　range　of　social,　environmental,　and　economic　factors　is　an　essential　component　of　sustainable　urban　development,　while　the　mapping　of　historic　buildings　which　can　be　archived　and　extracted　for　application,　is　the　basic　work　on　the　protection　of　historic　buildings　and　adaptive　reuse.　Traditional　mapping　methods　need　more　time　and　more　workers,　and　there　are　measured　omissions,　mistakes　and　other　issues　which　go　against　the　protection　of　the　measured　objects.　3D　laser　scanning　technology　is　a　new　technique　for　quickly　getting　three-dimensional　information.　This　paper　introduced　a　measurement　principle　for　3D　laser　scanning　technology　and　took　Shang　Shu　Di,　a　Ming　Dynasty　building　which　is　an　officially　protected　heritage　site　of　China　in　Taining　County　of　Fujian　Province,　as　a　case　study,　and　studied　the　application　of　mapping　historic　buildings　based　on　3D　laser　scanning　technology.　Then,　a　comparison　of　3D　laser　scanning　technology　with　the　traditional　method　of　detailed　components　mapping　has　been　illustrated　to　indicate　the　advantage　of　3D　laser　scanning　technology　in　historic　building　mapping.　Finally,　aimed　at　the　technical　problems　of　the　huge　amount　of　data　generated　in　the　application　process　and　the　software　defects　of　Cyclone,　this　paper　presented　two　specific　coping　strategies　which　are　＂reasonable　data　collection　and　processing＂　and　＂construction　of　historic　building　components　database＂.　©　SPSD　Press　from　2010,　SPSD　Press,　Kanazawa.
