%How to find the resolution of an matrix T which was formed from given data (Long, Lat, data). Difference between two long(lat)(117.000000000 117.033333333) position is 0.033333333degree or 3.69999.km All data point is at regular interval. What would be resolution of matrix and its image? please answer it.

A02=data_01(:,3);
A03=reshape(A02,541,541);
T=A03';
g=imagesc(T)

well
both answers are correct , simply one is the angular resolution and the orther one is the corresponding distance resolution on the sphere surface. Both values are interconnected (dx = R * dtheta) so pick the one you need.
