## Did you read the Contributor Guide? - Yes, I have read [Contributor Rules](https://sedona.apache.org/latest-snapshot/community/rule/) and [Contributor Development Guide](https://sedona.apache.org/latest-snapshot/community/develop/) ## Is this PR related to a JIRA ticket? - Yes, the URL of the associated JIRA ticket is https://issues.apache.org/jira/browse/SEDONA-516. The PR name follows the format `[SEDONA-XXX] my subject`. ## What changes were proposed in this PR? Introduces `RS_Interpolate`. Key features include: - This raster operator performs interpolation on a raster using the Inverse Distance Weighted (IDW) method. This method estimates cell values by averaging the values of sample data points in the vicinity of each processing cell. - The influence of a sample point on the interpolated value is inversely proportional to the distance from the cell being estimated, with nearer points having more influence or weight in the averaging process. - This technique is effective in scenarios where continuity of spatial data is important, and it is essential to estimate values for locations that do not have direct measurements, often represented by NaN or noDataValue in raster data. - Supports 2 modes, "Variable" and "Fixed" mode: - "Variable" mode adjusts the search radius to incorporate a specified number of nearest points within a set maximum distance. - "Fixed" mode uses a constant radius, expanding as necessary to meet a minimum point threshold. ## How was this patch tested? - Passes new tests ## Did this PR include necessary documentation updates? - Yes, I am adding a new API. I am using the [current SNAPSHOT version number](https://github.com/apache/sedona/blob/99239524f17389fc4ae9548ea88756f8ea538bb9/pom.xml#L29) in since `vX.Y.Z` format. -- This is an automated message from the Apache Git Service.
