收藏资源简介:
数据格式为ArcGIS支持的Shapefile矢量数据,共3个文件夹,分别为天津、长江三角洲和珠江三角洲。 1)天津 命名方式:TJ_PS_75_x,共7个子数据集。 其中TJ_PS_75_0 ~ TJ_PS_75_5每个子集均包含10万个PS点,TJ_PS_75_6包含73487个PS点。 每个PS点的属性表包括2017.3-2020.3期间该位置点的经纬度坐标、平均沉降速率(velocity)、相干系数(coherence)、逐月累积沉降量等信息。 2)长江三角洲 命名方式:SH_PS_75_x,共18个子数据集。 其中SH _PS_75_0 ~ SH _PS_75_16每个子集均包含10万个PS点,TJ_PS_75_17包含22722个PS点。 每个PS点的属性表包括2017.3-2020.3期间该位置点的经纬度坐标、平均沉降速率(velocity)、相干系数(coherence)、逐月累积沉降量等信息。 3)珠江三角洲 命名方式:GZ_PS_75_x,共24个子数据集。 其中GZ _PS_75_0 ~ GZ _PS_75_22每个子集均包含10万个PS点,GZ _PS_75_23包含25046个PS点。 每个PS点的属性表包括2017.3-2020.3期间该位置点的经纬度坐标、平均沉降速率(velocity)、相干系数(coherence)、逐月累积沉降量等信息。
The data is stored as Shapefile vector data supported by ArcGIS, consisting of 3 folders corresponding to Tianjin, the Yangtze River Delta, and the Pearl River Delta respectively. 1) Tianjin The naming convention is TJ_PS_75_x, with a total of 7 sub-datasets. Each of TJ_PS_75_0 through TJ_PS_75_5 contains 100,000 PS points, while TJ_PS_75_6 contains 73,487 PS points. The attribute table of each PS point includes the longitude and latitude coordinates, average subsidence velocity, coherence coefficient, monthly cumulative subsidence amount, and other relevant information of the location from March 2017 to March 2020. 2) Yangtze River Delta The naming convention is SH_PS_75_x, with a total of 18 sub-datasets. Each of SH_PS_75_0 through SH_PS_75_16 contains 100,000 PS points, while SH_PS_75_17 contains 22,722 PS points. The attribute table of each PS point includes the longitude and latitude coordinates, average subsidence velocity, coherence coefficient, monthly cumulative subsidence amount, and other relevant information of the location from March 2017 to March 2020. 3) Pearl River Delta The naming convention is GZ_PS_75_x, with a total of 24 sub-datasets. Each of GZ_PS_75_0 through GZ_PS_75_22 contains 100,000 PS points, while GZ_PS_75_23 contains 25,046 PS points. The attribute table of each PS point includes the longitude and latitude coordinates, average subsidence velocity, coherence coefficient, monthly cumulative subsidence amount, and other relevant information of the location from March 2017 to March 2020.
