To provide appropriate and uniform digital surface for further surface reconstruction, this paper departed from the feature of laser digitization, that is, measured points trend to distribute uniformly, and presented four sparse plans, according to classicality probability, for plane data points. On the assumption that local of surface approaches to a plane, these plans were extended to 3D spaces. Test to three actual measured data showed that the ways are very effective. In the actual process of sparseness, it needn't to consider about the surface idiographic features and avoid the traditional preprocessing, so it brought out quite convenience for practice.
