Descripción
Sumario:[EN] The PSIG software chain, which has been producing terrain displacement maps for one and a half decades now, has been entirely developed by the members of the Geomatics Division of the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC). Despite its high degree of automation, PSIG offers its users a noticeable degree of flexibility, making possible to control the relevant set of parameters defining how the processes involved in the chain will behave. However, these parameters, which are applied uniformly to the whole area being processed, may not be the best ones when considering specific local, critical areas. Running the PSIG software chain to process each of these critical areas using tailored sets of parameters is the solution to obtain a product with a good overall quality. However, identifying these areas without an appropriate set of analysis tools may prove very complicated. The VETools, the subject of this work, are targeted at solving this problem. With the VETools it is possible to perform the aforesaid tasks, namely, identifying - visually - the areas that should be enhanced and then relaunch their reprocessing with new control parameters, having the possibility to assess (again, visually) the results and thus rejecting or accepting these until a set of satisfactory solutions are found to be merged afterwards in a unique product with the requested overall quality.
