Website consists of 2 pages. Page 1: First page has two input menu boxes for ID & PW that are stored. Admin add/modify ID & PW information. If input of ID & P/W are correct then go next page 2. Page 2: 2 menu boxes for reading NMEA file from user PC and write image of google map displaying NMEA (longitude & latitude) at user PC. Displayed map with NMEA datas need zoom in &out. Position of each Lon & Lat to be displayed has an own color defined by times in the NMEA files that are available on $GPGGA of NMEA. There are 24 (hours) color codes are displayed next to the google map. 1. There are no graphic design such as pictures/images for background, menus, font Etc. but Admin will add it later so information of the way to update/maintenance are required with source codes. Text menu only required. Thank you.
