The case analysis this time is mainly to extract the value to the point in batches. In many cases, we have to perform year-by-year operations on the fixed vector, so we will repeat a lot of work. For this reason, the value extraction in ArcGIS is a very good choice. .
The purpose of this article is to look at land use change at these random points, since the data covers the types of land change from 1985-2020, the fastest local operation is through batch processing.
My vector, which are randomly picked sample points:
I need these years of land use data to extract one by one:
Find the extraction analysis function in ArcGIS and let it extract only to points:
In the process of batch operation in ArcGIS, whether it is input point features or input raster and output point features, batch filling can be performed, provided that the required file names are the same.

Select to add data directly after batch selection, all can be directly added to ArcGIS:
Results for the year:
We associate each table: or directly select the table from Excel in the conversion tool to excel and right-click to export in batches:
