| | What tools does it offer?
Eduspace introduces Earth observation techniques and applications to secondary school students with the help of two catalogues containing EO imagery, as well as a sophisticated image processing software package known as LEOWorks. ArcExplorer and ENVI FreeLook are software packages also used in some of the case studies.
Image Catalogue Viewer
The Eduspace Image Catalogue Viewer was developed by Terranova in collaboration with ESA/ESRIN. It allows the user to perform multi-mission inventory searches on ESA's main supported missions. Actual multiband imagery from different regions of the electromagnetic spectrum, including infrared, active microwave, and visible, can be downloaded.
You can download the Eduspace Image Catalogue application by clicking on the link on the right.
Install the Catalogue application on your computer by following the instructions given on the download page.
Once the Catalogue application has been installed, it will run independently from the Eduspace website, but you will still need to be connected to the Internet to access the catalogue.
You can also find the Eduspace Image Catalogue instruction manual on the right of this page.
The username and password made available for teachers to access the Eduspace Image Catalogue are respectively: 'Eduser' and 'space'.
LEOWorks
LEOWorks is an important feature¬ of Eduspace. It allows secondary school students to do actual processing of satellite imagery. LEOWorks is able to perform basic and advanced processing operations, such as geometric correction, pan-sharpening and image classification. Several tools are available, such as Geographical Information Systems (GIS) functionalities that enable the displaying, drawing and managing of information layers as points, lines and polygons, on top of images.
LEOWorks is a didactical tool with extensive help pages and an all-inclusive tutorial (see right of page). With the assistance of this documentation, students will be able to experiment with their own imagery and undertake their own processing. LEOWorks is compatible with data collected by several Earth Observation missions, and can read most standard image formats (e.g. jpg, tif, bmp, png).
LEOWorks 4 is the latest version of the software and it is platform independent (Windows, MacOS, Linux).
ArcExplorer
ArcExplorer is a freeware used to display and analyse layers of Geographical Information Systems (GIS). It includes a complete user guide and has been made available by ESRI, one of the leading providers of GIS software and GIS solutions.
