| 216689747 | MDU6SXNzdWUyMTY2ODk3NDc= | 1325 | extract values at nearest point with multidimensional latitude and longitude field | 13285597 | closed | 0 | 2 | 2017-03-24T07:55:53Z | 2019-02-25T01:16:40Z | 2019-02-25T01:16:40Z | NONE | How do I extract values at a specific latitude and longitude point when latitude/longitude values are 2-D array? I have a dataset with the following coordinates:
I want to extract value for at a specific latitude and longitude point and the exact latitude/longitude value is not in the coordinates. Then I started with calculate the distance between two point on Earth, and then get the (x_idx, y_idx) by minimize the distance. However, CPU and time costing is a result because of the large size of data. I'm wondering is there any other ways could make it less costing? |
