Integration dataset of Tibet Plateau boundary

This dataset contains five types of boundaries. 1. TPBoundary_ 2500m: Based on ETOPO5 Global Surface Relief, ENVI+IDL was used to extract data at an elevation of 2500m within the longitude (65~105E) and latitude (20~45N) range in the Tibetan Plateau. 2. TPBoundary_ 3000m: Based on ETOPO5 Global Surface Relief, ENVI+IDL was used to extract data at an elevation of 3000m within the longitude (65~105E) and latitude (20~45N) range in the Tibetan Plateau. 3. TPBoundary_ HF (high_frequency): This boundary is defined according to 2 previous studies. Bingyuan Li (1987) had a systematic discussion on the principles for determining the extent of the Tibetan Plateau and the specific boundaries. From the perspective of the formation and basic characteristics of the Tibetan Plateau, he proposed the basic principles for determining the extent of the Tibetan Plateau based on the geomorphological features, the plateau surface and its altitude, while considering the integrity of the mountain. Yili Zhang (2002) determined the extent and boundaries of the Tibetan Plateau based on the new results of research in related fields and years of field practice. He combined information technology methods to precisely locate and quantitatively analyze the extent and boundary location of the Tibetan Plateau, and concluded that the Tibetan Plateau in China extends from the Pamir Plateau in the west to the Hengduan Mountains in the east, from the southern edge of the Himalayas in the south to the northern side of the Kunlun-Qilian Mountains in the north. On April 14, 2017, the Ministry of Civil Affairs of the People's Republic of China issued the Announcement on Adding Geographical Names for Public Use in the Southern Tibetan Region (First Batch), adding six geographical names in the southern Tibetan region, including Wo’gyainling, Mila Ri, Qoidêngarbo Ri, Mainquka, Bümo La, and Namkapub Ri.４. TPBoundary_ New (2021): Along with the in-depth research on the Tibetan Plateau, the improvement of multidisciplinary research and understanding inside and outside the plateau, and the progress of geographic big data and Earth observation science and technology, the development of the 2021 version of the Tibetan Plateau boundary data by Yili Zhang and et al. was completed based on the comprehensive analysis of ASTER GDEM and Google Earth remote sensing images. The range boundary starts from the northern foot of the West Kunlun Mountain-Qilian Mountain Range in the north and reaches the southern foot of the Himalayas and other mountain ranges in the south, with a maximum width of 1,560 km from north to south; from the western edge of the Hindu Kush Mountains and the Pamir Plateau in the west to the eastern edge of the Hengduan Mountains and other mountain ranges in the east, with a maximum length of about 3,360 km from east to west; the latitude and longitude range is 25°59′30″N~40°1′0″N, 67°40′37″E~104°40′57″E, with a total area of 3,083,400km2 and an average altitude of about 4,320m. Administratively, the Tibetan Plateau is distributed in nine countries, including China, India, Pakistan, Tajikistan, Afghanistan, Nepal, Bhutan, Myanmar, and Kyrgyzstan.５. TPBoundary_ Rectangle: The rectangle was drawn according to the range of Lon (63~105E) and Lat (20~45N). The data are in latitude and longitude projection WGS84.As the basic data, the boundary of the Tibetan Plateau can be used as a reference basis for various geological data and scientific research on the Tibetan Plateau.

本数据集包含五种类型的边界。1. TPBoundary_ 2500m：基于 ETOPO5 全球地表高程数据，采用 ENVI+IDL 工具在青藏高原的经度（65~105E）和纬度（20~45N）范围内，提取了海拔2500米的数据。2. TPBoundary_ 3000m：基于 ETOPO5 全球地表高程数据，采用 ENVI+IDL 工具在青藏高原的经度（65~105E）和纬度（20~45N）范围内，提取了海拔3000米的数据。3. TPBoundary_ HF（高频）：该边界定义依据前两项研究。李炳元（1987年）对确定青藏高原范围及其具体边界的原则进行了系统论述。从青藏高原的形成和基本特征出发，他提出了基于地貌特征、高原表面及其高度，并考虑山脉完整性的青藏高原范围确定的基本原则。张一力（2002年）基于相关领域的新研究成果和多年实地考察，确定了青藏高原的范围和边界。他结合信息技术方法，精确定位并定量分析了青藏高原的范围和边界位置，得出结论：中国境内的青藏高原西起帕米尔高原，东至横断山脉，南至喜马拉雅山脉南缘，北至昆仑山-祁连山北麓。2017年4月14日，中华人民共和国民政部发布了《关于公布第一批青藏高原地区公众用字地名公告》，在青藏高原南部地区新增六个地名，包括沃卡营岭、米拉山、乔典尕博日、麦群卡、布莫拉和南卡布日。4. TPBoundary_ New（2021）：随着对青藏高原的深入研究，以及青藏高原内外多学科研究的提升和理解，以及地理大数据和地球观测科学技术的发展，基于 ASTER GDEM 和 Google Earth 遥感影像的综合分析，由张一力等人完成了2021版青藏高原边界数据的发展。范围边界北起西昆仑山-祁连山脉北麓，南至喜马拉雅山脉等山脉南麓，南北最大宽度为1,560公里；西起兴都库什山脉和帕米尔高原西部边缘，东至横断山脉等山脉东部边缘，东西最大长度约为3,360公里；纬度范围为25°59′30″N~40°1′0″N，经度范围为67°40′37″E~104°40′57″E，总面积为3,083,400平方公里，平均海拔约为4,320米。行政上，青藏高原分布在中国、印度、巴基斯坦、塔吉克斯坦、阿富汗、尼泊尔、不丹、缅甸和吉尔吉斯斯坦九个国家。5. TPBoundary_ Rectangle：根据经度（63~105E）和纬度（20~45N）的范围绘制矩形。数据采用纬度和经度投影WGS84。作为基础数据，青藏高原的边界可作为各种地质数据和青藏高原科学研究的重要参考依据。
