Google Maps is a widely used tool for creating custom maps with features like markers, layers, and icons, suitable for basic mapping needs. However, it has limitations in advanced features and real-time collaboration, making it less ideal for complex projects requiring interactive and collaborative mapping. Felt, a more sophisticated platform, addresses these limitations by offering real-time editing, enhanced visualization tools, and seamless data sharing, making it better suited for managing intricate workflows and turning static data into dynamic resources. Custom maps are valuable for organizing complex data into clear visual formats, aiding in presentations of complex statistics, tracking environmental projects, and managing business operations. While Google Maps serves as a good starting point for custom map creation, Felt offers a more advanced solution for teams needing enhanced collaboration and richer design options.
