Outline

This subject deals with WebGIS, very powerful systems for capturing, processing, analysing, visualising and publishing geospatial data distributed throughout the world on the Web, which is 80% of the data handled today. It will study:

  • GIS as the basis of WebGIS, using free software such as gvSIG and qGIS, carrying out practices with free software for Data Mining, Data Science and Big Data.
  • The most innovative methods of capturing geographic information, such as data from LiDAR flights, Remote Sensing satellites, GPS, Scanners, open data and other data capture sources such as drones; especially drones in Antarctica where the Research Group works, from which the professor is coordinator of the Geomatics and Decision Theory line.
  • As GIS on the Web Spatial Data Infrastructures (IDES) are tools with different levels of implementation, global, continental, national, regional, local..., the guidelines that allow them to be implemented at European and national level will be studied. Then different programming languages will be reviewed: GML, CityGML and Google's KML, JavaScript.
  • The CityGML standard will be studied, which allows interoperable 3D urban models to be made with other models such as BIM (Building Information Model).
  • Next, the potential of WebGIS services to visualize spatial data will be studied. Free spatial databases, PostGIS, will be studied. It will be implemented with free software, a WebGIS that includes the development of 2D and 3D viewers with free software and a specific geoserver to publish geospatial data.
  • Finally, it will be possible to contact the development of geospatial data Apps.

Learning Goals

  • Capture, analyse, display and publish geographically referenced information via the Web, as it is a high-quality information management system, capable of capturing and displaying free cartographic data and images hosted on web geoservers around the world sponsored by the Open Geospatial Consortium (OGC)
  • Obtain an appropriate usage level of freely available GIS software, especially for handling satellite images, aerial photographs, LiDAR data, Big Data, and other novel methods of GIS data capture.
  • Obtain an appropriate level of software utilization for the development of freely available web geoservers.
  • Obtain an appropriate level of use of software for the development of freely available web viewers.
  • Obtain an appropriate level of use of freely available spatial databases.
  • Get an overview of Geospatial Data Apps.
  • Link the software used with the software used in other subjects offered at the School. At the same time, students will be trained to capture, read, understand and analyse data, they will be able to carry out web queries of the territory and the integration of existing or designed elements, made from other programs, such as CAD design programs.
