Scale Web GIS With Time Zones and Other Services

In 2020 Flexatel created an information and sales portal for corporate clients in international companies.
The portal includes data on several thousand localities, including weather (downloaded from international sites), local time, currency exchange rates, city features, and direct costs, among other information.
The client intends to sell the portal to large companies for integration into their internal systems, to facilitate planning for business trips, conference calls, and the like.
The completed portal provides:
⁃ a convenient and illustrative cartographic basis
⁃ easy integration with internal corporate portals of international companies
⁃ ability to quickly coordinate meeting or conference call time by city location
⁃ excellent system performance results as required by the client
