Go Map!! vs RTAB

Go Map!! lets you create and edit information in OpenStreetMap, the free crowd-sourced map of your neighborhood and the world. Add shops and restaurants, streets, cycling and hiking paths, buildings, lakes and rivers. • Quickly add points of interest • Edit nodes, ways and areas • Track your location and heading • Create and resolve Notes • Supports arbitrary tag values • Full undo/redo support • Work offline and upload your changes later • Bing, Mapbox and Mapnik backgrounds, or customize with your own • See who last edited an object and when • Find other mappers nearby • Search for places using Nominatim • Free! No ads or in-app purchases For more information visit www.OpenStreetMap.org Free registration and acceptance of the OpenStreetMap licensing terms is required to upload your changes. Continued use of GPS running in the background can dramatically decrease battery life.

RTAB-Map (Real-Time Appearance-Based Mapping) is an Open Source LiDAR / RGB-D / Stereo Graph-Based SLAM (Simultaneous Localization and Mapping) approach based on an online incremental appearance-based loop closure detector. The loop closure detector uses a bag-of-words approach to determinate how likely a new image comes from a previous location or a new location. When a loop closure hypothesis is accepted, a new constraint is added to the map's graph, then a graph optimizer minimizes the errors in the map in real-time. An optional memory management approach can be used to limit the number of locations used for loop closure detection and graph optimization, so that real-time constraints on large-scale environnements are always respected. ARKit's visual inertial odometry (VIO) is used as the SLAM front-end for RTAB-Map (the SLAM back-end). * Note that unlike other scanning apps that optimize the map only after mapping, with RTAB-Map you get loop closure detection and map optimization online so you can have a live feedback to know when you have enough constraints in the map for good global optimization before stopping the scan. *** 3D reconstruction available only with LiDAR sensor. Features: * Online 3D scanning/mapping of the environment. * Online loop closure detection and map correction. * Save in DB format (RTAB-Map desktop and rtabmap_ros format). * Export in PLY, LAS or OBJ. * Multi-session mapping (save and continue later). * Use Apriltags to help finding loop closures in textureless environments. * Mixed AR/VR First-Person in visualization mode. * Raw ARKit data recording (up to 60 Hz!), useful to record long sessions without comprising battery life.
