convert raster ndvi to vector area grid

Global Mapper User
hi, im having problems trying to convert a raster image. I've got an NDVI image at a resolution of about 5cm and want to convert this into a 10m x 10m vector grid. I want each grid area to be given a value of 1, 2, 3 or 4 based on the average of the raster cells in each grid.
can you please help me with which functions to use.
the application is converting a ndvi image into a simplified grid of values that can be used for treatment like fertiliser on an agricultural crop.
thanks.
