The public health information is essential material for public health care planning and operating system. The updating data can help health care workforce to create health care scheme or public health policy that suit with community and people health context and then improve citizen’ quality of life. The geographic information system (GIS) is the technology which can be apply for support the healthcare workforce to collect and update data of health determinant and it is also have an ability to synchronize and analyze the real time data. The main propose of this study was to develop a mobile phone-based geographical information system for be like the real time health determinants data reporting system. The study was conduct under the developmental research design. There were divided into three phase; Preparation, Implementation, and evaluation phase by using focus group. The study result demonstrated that the developed system was compose of the part of data collection and the part of health determinant data report that can be display in various types of tables, charts and Google 360 degrees. Furthermore, this system was transform to be an application so everyone can reach it from App store or Google play store. The stakeholders found that the system was friendly for user because the system format is appropriate, very interesting, and easy for using. Moreover, the ability to analyze a real-time data is very useful for the health workforce; especially to detect the communicated disease like the Dengue fever for example. On the other hand, the barriers of using GIS was found. The users reflected that the coverage of internet network and internet access were the main obstacle. In conclusion, the developed system gave a lot of benefit for healthcare workforce but need to adjust or improve some function to make the system suit with other community context and need to prepare the internet network quality before using the system.
