The Humanitarian OpenStreetMap team has guidelines on `flying for UAV mapping <https://uav-guidelines.openaerialmap.org/>`_:
- `Choosing the right uav <https://uav-guidelines.openaerialmap.org/pages/05-choosing-the-right-uav/>`_
- `Choosing the right UAV <https://uav-guidelines.openaerialmap.org/pages/05-choosing-the-right-uav/>`_
- `Choosing the right sensor <https://uav-guidelines.openaerialmap.org/pages/06-choosing-the-sensor/>`_
- `Mission preparation <https://uav-guidelines.openaerialmap.org/pages/07-preparing-for-the-uav-mission/>`_
The guidelines are intended for mapping projects on islands, but have general use for all drone mappers.
See also DroneDeploy's guide on `Making Successful Maps <https://support.dronedeploy.com/docs/making-successful-maps>`_, which provides great tips on mission planning.
Finally, lens distortion is a challenge in projects requiring accurate 3D data. See our section in these docs on `Camera Calibration <using.html#calibrating-the-camera>`_.

.. Explaining the outputs structure
OpenDroneMap Outputs
====================
Listed below are some of the useful outputs ODM produces.
Point Cloud
^^^^^^^^^^^
``odm_georeferenced_model.ply/laz/csv`` -- The georeferenced point cloud in different file formats
.. figure:: images/pointcloud.png
:alt: image of OpenDroneMap derived point cloud
:align: center
3D Textured Model
^^^^^^^^^^^^^^^^^
``odm_texturing/odm_textured_model.obj`` -- The textured surface mesh
``odm_texturing/odm_textured_model_geo.obj`` -- The georeferenced and textured surface mesh
You can access the point cloud and textured meshes using MeshLab. Open MeshLab, and choose File:Import Mesh and choose your textured mesh from a location similar to the following: ``odm_texturing\odm_textured_model.obj``
.. figure:: images/texturedmesh.png

:align: center
Orthophoto
^^^^^^^^^^
``odm_orthophoto/odm_orthphoto.png`` -- The orthophoto, but this is a simple png, which doesn't have any georeferencing information
``odm_orthophoto/odm_orthphoto.tif`` -- GeoTIFF Orthophoto. You can use it in QGIS as a raster layer.
.. figure:: images/orthophoto.png

DTM/DSM
^^^^^^^
DTM/DSM will only be created if the ``--dtm`` or ``--dsm`` options are used and will be stored in:
* ``odm_dem/dtm.tif``
* ``odm_dem/dsm.tif``
