aggregate raster with special statistics

[asiaLACHIR]

hello


i'am beginner user of arcgis, and i need your help:

i have a land use map at 25 m and i want ti aggregate it to 250 m .

and For each new grid cell at 250 m, i need to carry over statistics of existing land cover types at 25 m and express
them as a percent of the total number of types contained in the 250-m grid cell.

the final result should be a multidimensional land use map at 250-m horizontal resolution containing the fraction of each type             within the 250-m grid cell.

can you tell me please if this can be done with arcgis, and how,,,

You can use the Aggregate and Con functions in the Raster Calculator.

For each land use code (e.g 9, 15, 32), run the Raster Calculator tool with the expression Aggregate(Con("landuse" == <landusecode>, 1, 0), 10, "SUM", "TRUNCATE"), e.g:

Aggregate(Con("landuse" == 32, 1, 0), 10, "SUM", "TRUNCATE")
