Datasets description

This dataset is based on Landsat OLI images, combined with ArcGIS and ENVI software, NDSI and Google Earth images, and uses semi-automatic glacier mapping methods to extract glacier boundaries. This data can provide basic data support for glacier research in the Tianshan region.

Base information

collect time	2016/09/01 - 2016/09/01
collect place	Tianshan Tuomu'er Peak area
altitude	2900.0m - 7400.0m
data size	9.1 KiB
data format	shp
Data spatial resolution (/ M)	30
Coordinate system	WGS84

Data source description

The original image is Landsat OLI land satellite image data, obtained from geographic spatial data clouds（ http://www.gscloud.cn/ ）Download.

Data processing method

1. The band ratio method automatically extracts the initial glacier boundary;

2. Manually revise the initial boundary.

Data quality description

The error can be attributed to the resolution of remote sensing images captured by visual interpretation of glacier boundaries. Therefore, the uncertainty of glacier interpretation can be calculated according to the formula: EA=N ·λ 2/2, where N is the number of pixels; λ is the resolution of different remote sensing images. The comprehensive evaluation shows that the uncertainty of visual interpretation of glaciers in the Tomur Peak area in 2016 was ± 0.96 km².
