Have you tried this web search: hector slam site:ros.org

hii @mike my aim is to scan an image of an object by moving a 2d lidar so i hope that mapping would help me do the same

Based on your comment above where you'd like to scan a (3D) object using a 2D lidar, I believe you're looking to stitch point clouds or align them in a particular way to represent the object. This process of spatially aligning or transforming point clouds is called point cloud registration. I would suggest you read up on point cloud registration, Iterative closest point (ICP) and the Point cloud library (PCL).

If you're looking for SLAM specifically, the Hector SLAM package or Gmapping are great starting points. The documentation for Gmapping is slightly better than Hector SLAM (which although a great package, hasn't really been documented too much).
