Modernizing spatial apps in the cloud with CARTO accelerates the development cycle by providing developers with technical resources to guarantee performance and scalability when integrating, visualizing, and interacting with large spatial datasets hosted in cloud data warehouses. CARTO offers a complete set of tools for interactive visualizations and applications using spatial data, drastically reducing development and maintenance timeframes and making visualization cost-effective. The platform is framework-agnostic, allowing developers to build their application using vanilla JavaScript or popular frameworks like Vue, React, or Angular. It uses deck.gl for visualization, which leverages web-GL technologies and GPU rendering for accuracy and performance. CARTO's cloud-native platform supports the visualization of large datasets directly from a cloud data warehouse, reducing the need for complex backend APIs or ETLs. The platform provides tools like Dynamic Tiling technology, pre-generated tilesets, CARTO Workflows, and the Data Observatory to enhance spatial application development.
