I have a gridded raster map produced from the NASA precipitation data over a country. The pixel type of the map is in floating point with 32 Bit pixel depth. Therefore, it does not have any attribute table. Now I have two questions:
If I use the Int command in the ArcToolbox to convert the map to Integer point pixel type I lose lots of information of the gridded data. What is the solution to convert it to Integer point pixel type without losing so much information. The data are rainfall amount in 10km *10km grid points and the values are mainly different in regards to their decimal and removing that convert the map into just 4 categories!
In the original map with the floating point with 32 Bit pixel depth, how can I extract the 10km *10km coordinates? It is too many coordinates (above 15000 grids) and I need a solution to extract it. Converting to ASCII did not help, by the way.
