Inputs:

• Two lat/lon point datasets
• Settings for output grid

Output:

• A spatially aggregated or interpolated grid

Algorithm Description:

• Spatial Interpolation: For each grid cell in the output grid, find nearest points within a search radius and calculate an estimate based on a weighted average of the point values.
• Sum within each grid cell: For each grid cell in the output grid, find all points that fall within the grid cell and calculate the sum total of their values.
