AN INTERACTIVE TOOL FOR 3D OBJECT EXTRACTION USING AIRBORNE LASERSCANNING DATA AND ORTHOIMAGES
Airborne Laserscanning Orthoimages 3D Object Extraction
2015/9/28
Light Detection And Ranging (LiDAR) provides reliable and detailed 3D data of the earth surface. This data combined with digital
Orthoimages can be used to create detailed 3D object models that are ...
CONCEPTUAL DEVELOPMENT OF AN ASSISTANT FOR CHANGE DETECTION AND ANALYSIS BASED ON REMOTELY SENSED SCENES

珠江三角洲网河区顶点河道断面侵蚀形态的演变
珠江三角洲 河道断面 侵蚀形态
2016/12/22
研究断面形态的演变特征，给上游来水来沙、人类活动影响的分析提供检验，也为下游水文地貌的演变提供科学依据。［方法］ 利用珠江三角州网河区三水站和马口站资料，通过提取反映河道断面侵蚀形态的指标，采用模拟退火算法优化的投影寻踪模型，综合解析河道断面侵蚀形态的演变特征。［结果］ 由于三水站2009年的虚实比远大于其他年份的虚实比，2009年三水站断面侵蚀形态异于其他年份外，其他年份侵蚀形态的变化较为缓和；...
