DESCRIPTION:This talk introduces a new drawing plugin for MapLibre: [maplib
 re-gl-terradraw](https://github.com/watergis/maplibre-gl-terradraw).\n\nHi
 storically\, both Mapbox and MapLibre have relied on an older plugin\, [ma
 pbox-gl-draw](https://github.com/mapbox/mapbox-gl-draw)\, to provide drawi
 ng functionality in **maplibre-gl-js**. However\, **mapbox-gl-draw** is no
  longer actively maintained\, making it increasingly difficult to use with
  MapLibre.\n\nAs an alternative\, [Terra Draw](https://github.com/JamesLMi
 lner/terra-draw) offers advanced drawing features for multiple mapping lib
 raries\, including **Mapbox**\, **MapLibre**\, **OpenLayers**\, **Leaflet*
 *\, **Google Maps**\, and **ArcGIS**\, all within a unified user interface
 . Compared to **mapbox-gl-draw**\, **Terra Draw** is significantly easier 
 to use. However\, integrating its full functionality into MapLibre still r
 equires extensive configuration.\n\nTo simplify this process\, I developed
  **maplibre-gl-terradraw**\, a new plugin that enables a pre-configured dr
 awing feature with a single line of code using `map.addControl`.\n\nWith *
 *maplibre-gl-terradraw**\, users can easily add drawing controls using `ma
 p.addControl(new MaplibreTerradrawControl())`.\n\nThis immediately grants 
 access to all drawing modes (point\, line\, polygon\, rectangle\, circle\,
  etc) powered by **Terra Draw**. The plugin comes pre-configured with icon
 s and additional functionalities\, such as:\n\n- Selecting and deleting fe
 atures\n- Downloading drawn features\n- Customizing Terra Draw options and
  styles\, as described in the documentation\n\nFurthermore\, the **measure
  control** allows users to:\n\n- Measure the distance of a line or the are
 a of a polygon\n- Query elevation data from raster DEM sources (MapLibre T
 errain\, TerrainRGB\, and Terrarium)\n\nIn this talk\, I will demonstrate 
 the core functionalities of **maplibre-gl-terradraw** and show how easily 
 you can integrate drawing features into your **MapLibre** applications.
