Analisis Perbandingan Formula Haversine dan Formula Vincenty dalam Perhitungan Jarak Destinasi Wisata Kabupaten Pacitan

In the development of geographic information technology, particularly in the tourism sector, accurate distance determination between two coordinate points has become very important. This research aims to compare the accuracy level and computational time efficiency between the Haversine Formula and Vincenty Formula. The method used is by testing distance calculations between user location and 15 tourist destinations in Pacitan Regency using both formulas. The test results show that both methods have high accuracy levels with an average difference of only 23.4 meters. However, in terms of computational performance, the Haversine Formula proves to be superior with processing times nearly three times faster than the Vincenty Formula. These findings indicate that the Haversine Formula is a more optimal choice for implementing tourist destination distance determination systems that require real-time computation or large-scale data processing.
