Hi all,
here is the report for the last week. I participated in the GRASS community sprint in Prague. We presented and discussed the temporal algebra. I implemented a lot new features like global temporal variables (td(), start_time, end_time, …), functions for if-statements, topological relationships for if-statements, a hash-operator (#) for map counting in conditional statements and finally get a new module t.select alpha version. In the next week I will test it, write documentation and start to implement the vector operations into the temporal algebra.
Greetings
Thomas
