Abstract: An optimal route derivation server configured to derive an optimal route of a ship includes a storage unit configured to store marine data including winds, wave heights, and currents by matching the marine data with sailing data at each time point and each location included in the sailing data of each sailing obtained from an Automatic Identification System installed on a ship, a corrected ship speed derivation unit configured to derive a first corrected ship speed by excluding an influence of currents from a speed of the ship for each sailing, a second corrected ship speed by considering an influence of winds on the first corrected ship speed at each location, and a third corrected ship speed by considering an influence of waves on the first corrected ship speed at each location, a speed down curve derivation unit configured to derive a first speed down curve related to winds and a second speed down curve related to waves based on a basic speed, the second corrected ship speed and the third corrected ship sp

Abstract: A server for providing weather data to a device with enhanced spatio-temporal resolution includes: a receiver configured to receive weather data from a weather model, the data having a predetermined spatial and temporal resolution; a converter configured to convert the received weather data into matrix data including forecast values for each latitude and longitude; an enhancer configured to subdivide the latitude and longitude of the matrix data into finer intervals than the predetermined spatial resolution and to enhance the spatial resolution by interpolating forecast values at the subdivided latitude and longitude positions; and a transmitter configured to transmit the weather data with the enhanced spatial resolution to the device.

Abstract: The present disclosure provides a method for providing route information for ship including coastal weather information, including: determining a standard route based on information about the origin and destination, determining at least one alternative route based on filtering information and the information about the origin and destination received from a user, and providing the user device with information about the standard route and the at least one alternative route such that the standard route and the at least one alternative route are output on a screen of the user device for comparison.
