The generation of a grid of templates and their placement in the parameter space is one of the problems that has to be addressed in the search for binary system coalescences detectable in interferometric gravitational wave detectors. We present a technique that computes the closed contour of equal match values around a point in parameter space and a first test of a template placement algorithm using these contours. This algorithm could be used to pave the parameter space. First results about the algorithm's covering efficiency are also presented.
