TRAKLA2 is a web-based learning environment for data structures and algorithms. The
system delivers automatically assessed algorithm simulation exercises that are solved using
a graphical user interface. In this work, we introduce a novel learning environment for spatial
data algorithms, SDA-TRAKLA2, which has been implemented on top of the TRAKLA2
system. Spatial data items are identified by a set of coordinates, such as x and y for two-

Executive Summary
TRAKLA2 is a web-based learning environment for data structures and algorithms. The system delivers automatically assessed algorithm simulation exercises that are solved using a graphical user interface.
In this work, we introduce a novel learning environment for spatial data algorithms, SDA-TRAKLA2, which has been implemented on top of the TRAKLA2 system. Spatial data items are identified by a set of coordinates, such as x and y for two-dimensional spatial data. The spatial environment contains new visualizations for representing spatial data, and a number of new exercises that cover a variety of spatial data algorithms.
