The coordinated response of fire has become a priority need for effective participation of actors. Within this scope, Geo-Information Technologies (GIT) will help to reduce of catastrophic results of disaster and protect lives and resources, with dynamic use of geo-data in fire disaster management. Interoperable geo-data is urgent need for fire disaster management. With assigned tasks, fire brigade is the most effective actor for the fire disaster management at different phases. In this study, actors that could act in a GIT based fire disaster management are defined. Activities in management phases of the possible fire disaster and geo-data needs to manage these activities were determined. According to this background, case activities such as producing fire risk map, optimizing locations of response teams, and the like were developed by using GIT. This approach can be a preliminary work to trigger effective and collaborate use of geo-data in fire brigade services.
