NAVTEQ/HERE Technologies has historically focused on utilizing various data sources, including sensor data, official sources, and partnerships with car manufacturers and other entities, to create and maintain their digital maps and location services.
Crowdsourcing, which involves gathering data from the public or users, is a commonly used approach in many mapping and navigation services. However, specific companies may have their own strategies and preferences when it comes to data acquisition.
It's possible that NAVTEQ/HERE Technologies has chosen to rely less on crowdsourcing and prioritize other data sources and partnerships to ensure the accuracy and reliability of their mapping products. However, I cannot provide information on their current beliefs or strategies since my knowledge is based on information available until September 2021. For the most up-to-date and accurate information, it would be best to refer to official statements or communications from NAVTEQ/HERE Technologies themselves.
