Over Mijn Dak 2.0
Over Mijn Dak (OMD) is a website/mobile app that offers people living near Schiphol an easy way to file complaints about noisy planes coming over their roofs. Version 1 has been operating for a few years now (overmijndak.ozv.nu). But its capacity is too low for the amount of users. And based on a survey among users we want to develop a new version (version 2) with slightly other functionalities.

Functional requirements based on findings from a survey among OMD users (from 20 October, 2025, see appendix).
OMD must (among other things) be usable as a mobile app on iPhone and Android.
With the press of a button, you must be able to submit a complaint to BAS and Vliegherrie when a noisy aircraft passes overhead.
The complaint automatically includes: time, address (default or based on GPS), noise level (measured).
The user can add to the complaint: perceived noise level (noisy / extremely noisy), short description or a choice from: part of the day/time (I want to sleep and aircraft keep me awake), number (too many aircraft per hour), duration block (it does not stop and just keeps going).
OMD keeps track of how many complaints you have already submitted and prevents you from becoming a frequent complainer.
OMD automatically prepares daily complaints for periods based on configurable critical frequency and configurable critical altitude.
Before sending, the user can choose which critical period(s) of that day they want to complain about.
There is also an option to complain fully automatically about the first or longest critical period, or the longest critical period during the night.
