Latest Patents

Chamaa is credited with 1 patent, titled “Storing Map Data Based on Metadata.” The invention describes ways to generate, maintain, and access maps made up of discrete regional tiles. A map manifest can point to map content and may use a recursive structure that references other manifests.

The patent also describes storing map files with content-based hash values, which can be included in filenames or URIs. Vehicle computing systems can compare these values to identify changed files that need downloading and to check the accuracy of downloaded files. This approach is designed to reduce duplicated storage and support efficient updates.
