A Study of Discrimination Criterion for Extraction of Linear-Circular Structure of Remote Sensing Image With Bainiuchang Silver Polymetallic Deposit, Yunnan Province, China as example

摘要

This paper analyzes the factors including geological factors, imaging factors must be considered when extract Remote Sensing image linear-circular structure. And summarizes six criterions to recognize and distinguish the types of linear-circular structures. These criterions successful applied to extract Lands at ETM+image linear-circular structures in Bainiuchang silver Polymetallic deposit.
