YUSIIP was born from the research work of Adolphe AYISSI ETEME (2002-2007) which deals with the study of the mechanisms of integration of heterogeneous and incomplete information systems in order to allow decision-making assistance in urban development, In a context of African cities marked by a lack of resources, insufficient consultation between the various stakeholders and scattered information, difficult to access and not very reliable. The core of the YUSIIP platform is its Distributed Data Warehouse (EDD), which capitalizes data and knowledge related to the following urban themes: environment, living environment, transport, infrastructure, etc. Finally, YUSIIP aims to offer a local monitoring tool to monitor and compare the evolution of the city.
YUSIIP is an information portal about the city of Yaoundé. The objective is to collect, collect, in the same place, information on urban development. The Internet user will find news, key figures classified by theme, documentation, current projects and will also be redirected to the websites of the various partner institutions. It is a collaborative project (the production of information is done in collaboration with other urban actors), evolutionary (every day, new information, indicators, themes, partners, functionalities, are added) Citizens, administrations, politicians, public and private organizations, scientists, the media) by offering products that meet their different needs (tables of figures and graphs for comparison, maps for visualization, metadata for understanding, etc.). ).
Urban data are the basic building blocks and conditions necessary for the implementation of sustainable, innovative and dynamic urban development. The International Conferences HABITAT II (1996) and HABITAT III (2016) recognize the fact that efficient and effective use of available urban data is essential to systematize, professionalize and optimize cities. The mastery of data and ICT (Information and Communication Technologies) will make it possible to improve performance on urban (thematic) fields. In addition, urban data serve as the basis for many applications, the production of new services and the creation of a new relationship with city dwellers. YUSIIP is implementing this new way of organizing knowledge sharing.
There is no comprehensive knowledge about cities in Cameroon. At the moment, the information collected is limited to their producers and / or users for their daily activities. They are therefore scattered, difficult to access and are not shared. The task of YUSIIP is to build an overall vision of the urban situation of the city of Yaounde, the political capital of the Republic of Cameroon via the establishment of a Multi-Source Information System (SIMS). The idea is to exploit the data accumulated by the public and private actors involved in urban management and planning to improve the living environment of the populations. The aim is to set up a platform that can capitalize urban data and produce indicators on the basis of which dashboards will be built.
The task of YUSIIP is therefore to make available the data produced by all the actors: ministries, public and private bodies, CTDs, non-governmental organizations, associations, social networks and connected objects. The "Sources Data" link gives access to an electronic directory of urban Yaoundé data (REDUY). On-line access to REDUY will prevent current and new urban actors from doing the same thing again, seeking to collect information that exists elsewhere. It will make it possible to reconcile sources of data which were not at the beginning, for ever richer uses: Big Data, Open Data, etc. And could trigger creative reflexes among urban actors: "Ah if I had these data there, I could ...".
YUSIIP treats different urban fields (environment, living environment, infrastructure, transport, education and training, etc.) and implements datasets. The main datasets include historical, demographic, local, geo-referenced or geospatial data, etc. These data will be used by journalists, researchers, businesses, municipalities, but also by the entire population. We are increasingly encouraged by the fact that public administrations and public and private enterprises, which have initially reacted by a kind of mistrust of data release / sharing, are gradually accepting it For the development of data ecosystems. Synthetic urban memory will value the data and will allow the emergence of unexpected but relevant applications.
In terms of urban development, it is important to ensure that urban actors and city dwellers who work together on many initiatives know where to find the data and how to use it. Opening up data means making the data available to users so that they can be used freely without cost or limitation. This will generate a large number of new services and new ways of working (cooperation, information sharing, creation of public applications based on data, etc.). We agree with Marieke Schenk that the opening of data generates four types of values: economic (it is a potential source of profit for established companies and start-ups), societal (serves to improve the quality of Democratic (people can see what is happening and interact) and systemic (data ecosystems benefit everyone).
For Cameroon's cities, data growth is an opportunity to face the challenges they face. And especially that of doing better with less. As we have pointed out, the urban data cover a variety of fields. With the exponential development of digital technologies, the idea is to create value from large volumes of data produced, stored and analyzed by urban actors. It is in this perspective that we are going to: - build a truly agile and resilient city; - develop indicators to measure the performance of urban services and policies; - carry out cross-studies of data and produce predictive analyzes. Urban data creates a chain of responsibility ranging from the office of the Government Delegate to the computers of the various public and private bodies.
The different actors often work on common objects, but they nevertheless tend to treat each one of them, to reproduce each of the same databases. If each urban actor communicates to others what data he has at his disposal, different possibilities could be opened: limiting redundancies, comparing / cross-referencing information, improving the legibility of urban action, sharing and collaborating. The idea is to implement a partnership approach involving a group of urban actors as well as the inhabitants to co-produce or co-build the data and put it online ("Intelligent Community" around the data). The task is to get the actors to consider the data as a resource of the overall strategy of innovation, performance and to suggest that YUSIIP be integrated into a city project.
