The project

The aim of our Web GIS is to build an important instrument which can be used in countries of the world where the lack of qualified technical staff and the poverty do not allow the corrected management of the territory. In particular, DIPECHO project (Disaster Preparedness European Community Humanitarian Office), developed by COOPI (a non governmental organization), has the aim to reduce different kinds of risk (as for example landslides, floods, frost, etc.) in the Muñecas municipality. This municipality, which is located in La Paz plateau, is really poor and presents many geographical disadvantages due to its heterogenous topography (from 600 m to 5200 m height). Therefore, it is really difficult for the ONG operating in the territory to build and manage structures of absolute necessity, like hospitals and centres for primary aid. Many surveys and researches have been carried out in order to produce risk maps. The data collected, initially elaborated with ArcGIS, are vectorial files in shapefile format.

Our activity

The first step of our work has been the preprocessing of our data. Using Autodesk Map and Open Jump we have “cleaned” our data, correcting digitalization mistakes and creating topologies with the purpose to obtain consistency in our informations. Some of the more frequent errors we found have been the presence of points outside the border of Muñecas municipality, roads and/or rivers not correctly connected and semantic inconsistency (as for example the overlapping between areas subjected to floods and safe ones). The removal of these errors is fundamental for obtaining good results, having the possibility to make queries on “clean” and well organized data.
