General availability: Azure Data Explorer adds new geospatial capabilities
Дата публикации: 17 мая, 2023
We are excited to introduce three new functions for geospatial analysis in Azure Data Explorer: geo_point_buffer, geo_line_buffer, and geo_polygon_buffer. These functions allow you to create polygonal buffers around geospatial points, lines, or polygons, respectively, and return the resulting geometry. You can use these functions to perform spatial operations such as intersection, containment, distance, or proximity on your geospatial data, or to visualize your data on maps.
For example, you can use geo_point_buffer to create a 10-kilometer radius buffer around a point representing a city center, and then use geo_intersect to find out which other points representing locations of interest fall within that buffer. You can use geo_line_buffer to create a 200-meter width buffer along a line representing a road or a river, and find out which other lines or polygons representing regions or boundaries cross or overlap with that buffer.
To learn more about these functions and see some examples, please visit the following links:

- geo_polygon_buffer: https://learn.microsoft.com/azure/data-explorer/kusto/query/geo-polygon-buffer-function
We hope you find these functions useful and we welcome your feedback and suggestions. Happy querying!
