This practice aims to unify the large amount of cartographic data in a single viewer, as it can be accessible for both professional and general users.
The main problems are the dispersion of information and the need of a simple and universal accessible digital cartography. Some projects offer very varied information and it is necessary to visualized it in a single screen, in order to compare cartographic information about different themes.

Another added problem is the large amount of information generated by different departments of regional ministries that must be managed and put at the service of the departments and users.

Through this project, it is possible to access to a complex cartography by the great amount of data handled (1110 layers) but simple in its visualization and handling. Centralizing all the information in a single viewer.

This project benefits all the departments of regional ministries that work with cartography and external users who want information on different thematic cartographies. This practice makes the information available to professionals (both civil servants and external technicians) and to everybody wanting to consult these thematic maps.


Resources needed

Technical and human resources from the public administration. Technicians and administrative staff of several regional ministries working part/full time in this project.

Evidence of success

This practice allows access for civil servants, external technicians and non-specialized citizens to more than 1100 layers of information integrated on a single screen.

Support 24 WMS technical services.
Information handled by 2 regional ministries.
Information used by 35 central departments and kept up to date.

Difficulties encountered

Lots of data, which are difficult to handle.
Very scattered information.
The existing interfaces are complicated.
Future actions to be undertaken are difficult to implement, so future expenses could not be contemplated.

Potential for learning or transfer

How to handle large amount of data (1100 layers) generated by many departments and put this data to the service of official public, external companies and non-technical users.

It is important to see the interest of users in managing information about protected natural spaces when planning works and how protected areas and current and future infrastructures interfere with each other.

This tool allows to display on a single screen and through a simple interface, large amounts of data from different cartographies. It is possible to select the data series to be visualized, as different layers of information, and then see how the different infrastructures, protected areas and future infrastructure interact among them.
