A good planning is a key factor for the success of a GPS survey. A realistic forecast of the DOP requires to take into account the obstacles that can hide part of the sky.

In practice it is relatively easy to take into account the various obstacle in the planning of a static survey, but it is more difficoult to do the same for a kinematic survey.

Abstract
A good planning is a key factor for the success of a GPS survey. A realistic forecast of the DOP requires to take into account the obstacles that can hide part of the sky. This is specially true in a mountaneous region (natural obstacle) and in the urban area (artifact obstacle). In practice it is relatively easy to take into account the various obstacle in the planning of a static survey, but it is more difficoult to do the same for a kinematic survey. In the present work an authomatic procedure for the planning of a kinematic survey has been realized with a dedicated procedure inside a GIS. The realized procedure is interfaced with the almanac, a DHM for the planning in M.A. and a carthographic data base for the planning in urban areas (still in project) and computes the DOP with the standard algorithm for the points in a given trajectory.
