Canal width measurements from backfilled and reference canals in coastal Louisiana marshes from four time points (1998, 2004, 2010, 2017)

Google Earth photographs for January 1998, March 2004, October 2010, and February 2017 were used to measure the width of eleven backfilled and reference canals in coastal Louisiana marshes as part of a study investigating the impact of canal backfilling as a restoration technique.本研究以运河回填修复技术的影响为探究对象，采用1998年1月、2004年3月、2010年10月及2017年2月的谷歌地球（Google Earth）影像，对路易斯安那州沿海沼泽中的11条回填渠道与对照渠道的宽度进行了测量。
