Gridding of data at district level and retrieving a 3 column format of the data for each grid as a latitude longitude and parameter value

i have data of a variable on district level for the whole country. i need to grid the data to a resolution of 0.1 deg X 0.1 deg resolution. Then i need to retrieve the variable value for each grid in a n x 3 format. where n is the total no of grids formed and 3 columns representative of latitude value, longitude value (representing the grid) and the corresponding value of variable value. Is this possible by using matlab. if yes please let me know how as soon as possible.

You can make it easier for him if you post your data along with code to read it in. Use the paper clip icon.

I need to grid this to resolution of 0.1 deg x 0.1 deg and retrieve the data of each grid.

@Harini! Please post your data as mat - files

[Harini]

i dont have them as mat files. i have the image file of the actual emission or a exel spreadsheet containing the emissions, which has to be gridded to a resolution of 0.1 x 0.1 deg and the data of each grid cell has to be extracted.

is there anyway mapping toolbox be used to serve my purpose. how to use geoloc2grid function if you have a map as image.
