I am a college student trying to design and develop an indoor navigation map web application that could provide directions in multiple levels similar to the SM Megamall Map in their website (see the picture or link below).
What would be the optimal SDK or API to developed this project?
SM Megamall WebApp Map Link: https://www.smsupermalls.com/maps/sm-megamall/?gclid=EAIaIQobChMI38SyhMOK_QIVV1tgCh121AIYEAAYASAAEgKdavD_BwE#/
Thank you in advance for those who would give their pointers and advice
