Aim of the project

This project has been developed for the Territorial Information Center of the Junta de Castilla y León between 2017 and 2021, and the main objective has been the development of several applications to support the Spatial Data Infrastructure, for which this organization is responsible:

  • Map viewer
  • Metadata catalog
  • Application for editing toponymy
  • Etc.

Specifically this Viewer tries to give the citizen an application that facilitates the consultation of spatial data provided by the Junta de Castilla y León, and that is fully usable from any device whether PC, Tablet or Smartphone.

It is actually the second version of the viewer, the first was published in 2018 and, in this one, not only the design has been changed but also some of its features have been expanded.

Due to the large amount of information available to this organization, one of the fundamental challenges was to structure the functionality in an intuitive way so that access to the data could be done in an easy way by any citizen, technician or layman in the subject.

In addition to the functional challenge, this project faced the objective of developing all the activities under technology without licensing costs so in the case of the viewer, technologies involved are completely OpenSource aligned with the rest of the components that make up the SDI.


Regarding the functional part of this Viewer that has been presented this week, it is worth mentioning the following functionalities:

Predictive textual search on the directory of layers proposed, by including the text in the search box, it filters on the directory of layers those that contain that text string in its title, this makes that having a very large number of layers the user can find in a very easy way the one you want to load in the viewer.

Automatic layer activation when loaded, once the user selects the layer he wants to load from the directory, it is automatically added to the viewable layers area and marked as active layer, this property will make the identification of elements to be done on that layer and other tools such as the buffer tool that will act on that active layer.

Simple programming of the thematic search, this thematic search tool on certain layers has been developed so that the TIC staff, by means of a very simple edition, can expand or change the layers and options of search that the application provides.

The application gives the option to choose what type of symbology you want to apply to a layer from among all those proposed by TIC, so that as the application also allows you to incorporate the same layer several times, you can get different themes of the same layer in the application.

If we add to this the availability of a simultaneous map comparator, in which different layers can be painted on each of the maps, we obtain a very powerful tool for comparing spatial information.

It has been added in this version of the Viewer, other tools like the drawing of a buffer on an element of the active layer, in a very simple way the citizen will be able to obtain on the map, the drawing of the area of influence, at the distance that he chooses of an element of the map that he has selected.

In short, an evolution of the existing viewer that has closed 4 years of project during which needed technical assistance has been given to TIC staff in the development of GIS/SDI applications and that has resulted in obtaining quality products widely used and needed by citizens. Also, the Territorial Information Center has shown its total satisfaction with the Systems Area of COTESA.

It is one more example of the success derived from the deep specialization that COTESA has in this sector and that makes us be among the leading companies in the development of applications related to the territory.

A development team that in terms of Spatial Information Systems and Spatial Data Infrastructures has worked and is working developing viewers, evolving their SDI’s or undertaking tasks of adaptation to INSPIRE directive in many other administrations such as:

City Council of A Coruña, Government of Cantabria, City Council of Bilbao, Government of Aragon, City Council of Valencia, Community of Madrid, Autonomous Community of Extremadura, City Council of Cáceres, Autonomous Community of Andalusia, City Council of Seville, Consell de Mallorca among others.
