GPX Route Editor

# GPX Route Editor This is a lightweight GPX trajectory editing tool running on the LazyCat microservices platform. It allows users to upload, view, edit and optimize GPX route files, making it particularly suitable for outdoor sports enthusiasts to organize trajectory data. ##Main functions * ** Visual map **: Based on OpenStreetMap and Leaflet, it clearly displays the trajectory. * ** Multi-file support **: Supports uploading multiple GPX files at once. The system will automatically identify and retain different trajectory segments, and will not ** create wrong straight connections between different files (i.e.,"red line" problems). * ** Drag and drop editing **: * ** Move points **: In edit mode, you can directly drag blue dots on the map to adjust the route. * ** Delete point **: Click on a single point to view coordinates or delete it. * ** Batch operation **: * ** Batch selection **: Click the "Batch Selection" mode to support holding down the `Shift` key and clicking on two points to automatically select all points between them (turn red). * ** Batch Delete **: After selecting it, click "Delete Select" to clear excess traces with one click. * ** Intelligent deduplication **: The one-click "deduplication" function automatically deletes redundant points that are too dense (less than 5 meters), reduces the file size, and retains the trajectory shape and section breakpoints. * ** Export data **: Download the compiled trajectory into a standard GPX file. ##User Guide 1. ** Upload files **: * Click the **"Upload GPX"* button to select one or more `.gpx` files. * The map automatically zooms to show all trajectories. 2. ** View and Preview **: * The default is in "Preview" mode, where you can zoom in and out of the map to view the route. * Click the **"Preview/Edit"* button to switch modes. 3. ** Editing trajectory **: * Switch to **"Edit"** mode (when the button is displayed as "Preview", it is in editing status, and blue dots will appear on the map). * ** Move **: Hold down any blue dot and drag it. * ** Delete a single **: Click the dot and click "Delete Point" in the pop-up bubble. 4. ** Batch deletion **: * Click the **"Batch Select"** button (turns green). * Click on the start point, then hold down the Shift key and click on the end point.
