从纬度和经度点创建位置网格

Question

I have two data sets: one of latitude and one of longitude. Both of these datum are 336x264 in size.

I would like to use MATLAB to turn this data into a grid of of position points.

So basically from this:

to this:

I don't want to reinvent the wheel here if there is a standardized method of going about this so I figured I should see if the community had any pre-existing resources for this sort of task!

If you have the mapping toolbox, you can do this with the projfwd function:

% First, create the projection struct
mstr = defaultm('mercator'); %Or whatever projection you want to use

% Then, project your points
[x,y] = projfwd(mstr,lat,lon);
