FME (Feature Manipulation Engine) is a handy tool that works great with GIS. If you're just starting out, FME’s simple drag-and-drop interface helps you move and convert data between different formats (like turning CAD files into GIS layers). As you get more comfortable, you can use FME to automate boring tasks, clean up messy data, and connect different datasets. For experts, FME can handle big, complex jobs—like processing LiDAR, working with cloud data, or running custom scripts. Whether you're a beginner or a pro, learning FME with ESRI GIS saves time and makes your mapping and data work way easier.
