The JATAYU Decision Support System (DSS) for air transportation safety implements a feature that displays data along the flight path (currently, the flight path is a straight line from departure to arrival airport's coordinates). To obtain the data, the interpolation method is used to provide more detailed information. There are two interpolation methods tested in this study, namely Bicubic interpolation and Nearest Neighbour interpolation. The current resolution used in the decision support system is 5 km, while the produced interpolation data should ideally have a higher resolution. Data with 2.5 and 1 km resolution are generated to act as comparison data. The case study areas are the islands of Java, Bali, and Nusa Tenggara. Based on the test results using Mean Absolute Scaled Error and Normalized Root Mean Squared Error, both methods show almost the same interpolation results. However, Bicubic interpolation gave slightly better results than Nearest Neighbour interpolation.
