DISTRILAKE
Project Definition
The main idea of DISTRILAKE project is the integrate and coordinate manage of the available reservoirs in
Lake Como basin – see Figure 1- (alpine hydroelectric reservoirs, available water in vadose zone and the
water table) and the lake, to increase the total efficiency of the system and its capacity of satisfy many
users, especially in water stress conditions.

Project Definition
Distrilake Geoweb System
Data Model
Web Services
Consist in the analysis of requirements and creation of
the data model of the integrated water system in a
heavily industrialized area and of the water cycle.
Implementation of the database and information
collection.
For the development of the DISTRILAKE project is
essential to have a model and data structure and a
consequent web geo- service (and viewing /
management client) to enable the collection and
updating of all comments and information relating to
water service and cycle of the waters of Lake Como.
The system has to make all data of interest immediately
and easily available to the participants in the project
and later to all stakeholders.

14. Metadata
Definition
Metadata contains information on the following aspects:
a) conditions applying to access and use of spatial data sets and
services relevant and, where applicable, corresponding fees;
b) the quality and validity of spatial data sets;
c) the public authorities responsible for the establishment,
management, maintenance and distribution of spatial data sets
and services;
d) limitations on public access and the reasons for such
limitations.

GoodMorningeveryone. Iamgoing to present the DISTRILAKE moduleregarding the geoweb System
The presentation is divided in 5 parts: one regarding the main objectives of the project and the geoweb system, with a brief explanation about SDI and web services, followed by a description of the methodology to implement and the work done so far. Later on we are going to discuss about metadata and finally a proposal for next activities and the interaction with the other modules of distrilake project.
The main idea of DISTRILAKE project is the integrate and coordinate manage of the available reservoirs in Lake Como basin and the lake, as we can see in the figure, in order to increase the total efficiency of the system and its capacity of satisfy many users, especially in water stress conditions.Theprojectisdivided in 4 modules, and I amgoin to talk about the first onewhichis the Distrilake Geoweb System.
This module consist on one hand in the creation of a data model for the whole water system, at least with the information that we already have, which leads to an implementation of a data base populated with the available data, just to have an idea of how it can be and the collection of information necessary to the project.On the other hand, the data must be available and share with the stakeholders like universities, governmental institution and in the future also, the community; and this data sharing should be done with the international standards, so web geo services must be implemented to enable the collection and updating of data in a interoperative way.So, summarizing, the module consist in the creation of a data model and the implementation of the required web services for data sharing. The data model and the web services implementation will depend on the information available of course and also on the collaboration with the government agencies and the institutions that produce and collect the data. Is not an easy task, but the idea is to demonstrate how data sharing can be done and how this can be an interesting tool, not only for the academia but also to the community in general.
The data that is being considered is all data that defines the Water cycle as its interact with land, that include also interaction with population ( water demand, water pollution…)
