Where can I get terrain data for a small area?

I am looking to get sample terrain data that is no more than 1 km x 1 km with 1m resolution. Is there a way to convert any particular terrain map data format to a simple N x N matrix that is N-meters by N-meters, with entries in terms of altitude in meters?

the data you will recieve will probably be a 1.000.000 x 3 matrix (first column for x, second for y and last one for altitude)
% i guess you load the data, lets name it data
