A Study on Coastline Extraction and Its Trend Based on Remote Sensing Image Data Mining

Table 1

Image details in 2007–2011.

Period	Satellite designation	Spatial resolution (m)	Quantity (scenic spots)
2011	HJ-1A	30	65
2010	HJ-1A	30	42
2009	HJ-1A	30	34
2008	CBERS-01	20	86
2007	CBERS-01	20	63

HJ-1A satellite is the abbreviation of environmental and disaster monitoring and forecasting; CBERS-01 satellite was jointly invested in and developed by China and Brazil on October 14, 1999. Because HJ-1A images and CBERS-01 images are low-resolution areas, the results of shoreline extracted have small differences, but this does not affect this study.
