> Maps – Amazon Location Service lets you create maps that make use of data from our partners. You can choose between maps and map styles provided by Esri and by HERE Technologies, with the potential for more maps & more styles from these and other partners in the future.
Amazon has dropped a ton of cash into maps. They won't use google for.. reasons, and there's a pretty limited selection of providers, including OSS offerings. A lot of this data has probably been enriched by the logistics arm.
Amazon has been using HERE maps internally for many years. It was the map included in the Fire phone and tablet, and also it's used in the online shop, such as for showing the parcel on the map, among other things. When I left HERE it was also heavily using AWS, so it's a two-way relationship.
For those who may not be familiar with HERE, they're huge on Enterprise, especially in Automotive, logistics but also on public sector.
HERE used to be part of Nokia and used to power their maps application. It's now owned by a wide consortium where the well-known German car making companies still have a majority. They also heavily use HERE maps and location based services, as many other car makers do. Not sure if they still do, but when I left, it was heavily used by Microsoft for Bing maps. Yahoo and Facebook maps were all based on the HERE map data and used many of the the same backend services.
Note: I currently work at AWS and previously worked at HERE but this message is not written on behalf of my current/former employer.
