Grab is a leading technology enterprise operating within Southeast Asia. Recognizing the inherent complexity of navigation within the region due to intricate road networks, Grab embarked on a strategic initiative in 2017 to address this challenge. This endeavor culminated in the inception of GrabMap, an internally developed mapping solution tailored to the unique geographical intricacies of Southeast Asian countries. Leveraging a blend of manual mapping processes and advanced Machine Learning algorithms, GrabMap was meticulously crafted to enhance accessibility to remote and previously uncharted locales. This initiative underscores Grab's commitment to optimizing its service offerings and fostering greater connectivity across the region.
