This time we bring you DEM terrain data with a resolution of 30 meters - STRM elevation data! This data was measured jointly by the U.S. Space Administration (NASA) and the National Surveying and Mapping Agency of the Department of Defense (NIMA). The data is very large due to its high accuracy, and most users should not be able to open the data nationwide. Therefore, we process this data for data in provinces and cities across the country, so it is convenient for everyone to use!
You can reply to the keywords on the official account 1206 Free to obtain 30-meter-precision DEM terrain data of any province in the country, including data across the province and data across every city in the province! You can get data directly without forwarding the article! Note that because the data is large, national data is not provided! The following is a detailed introduction to the data: 01 data preview
1. The province-wide terrain (the range is greater than the province boundary)
Let’s take Hubei Province as an example to preview . splicing the grids involving the scope of Hubei administrative divisions to get a larger range of terrain than the administrative boundary of Hubei Province. The reason for providing this range is that some friends may want to use their administrative boundaries to cut data. In this case, they can only be cut based on a larger range of terrain! 2. The province-wide terrain (the scope is consistent with the province's boundary) 

3.Topographic of cities in the province
Let’s take Hubei Province as an example. In addition to providing the province-wide terrain, we also provide the terrain of each city in 13 prefecture-level cities in Hubei Province. Let’s take Wuhan as an example: 02 data details
