In our project, we have created a user-authorized staff relationship which is managed over a mobil app and a web app. By user's firecalls, data which are taken from user is being calculated to find accurate place of fire. Then, using a dataset, we calculate which way is fire going to spread. We have created a mathematical formula to calculate it. This will help firefighters effectively arrive to right place (the way it spreads) and controll wildfire. Our formula is also giving a constant which ables us to measure risk of the wildfire. According to the risk, we will handle evacuation of people under risk. The last but not least, over time, by collecting data from wildfires we will have a big data which has huge potential to make estimations in future about similar wildfire emergencies.
