A free, user-friendly, extendable application and [API](http://docs.webodm.org) for drone image processing. Generate georeferenced maps, point clouds, elevation models and textured 3D models from aerial images. It uses [OpenDroneMap](https://github.com/OpenDroneMap/OpenDroneMap) for processing.
If you know Python, web technologies (JS, HTML, CSS, etc.) or both, it's easy to make a change to WebODM! Make a fork, clone the repository and run `./devenv.sh start`. That's it! See the [Development Quickstart](http://docs.webodm.org/#development-quickstart) and [Contributing](/CONTRIBUTING.md) documents for more information. All ideas are considered and people of all skill levels are welcome to contribute.
We recommend that you read the [Docker Documentation](https://docs.docker.com/) to familiarize with the application lifecycle, setup and teardown, or for more advanced uses. Look at the contents of the webodm.sh script to understand what commands are used to launch WebODM.
Task output or console shows one of the following:<ul><li>`MemoryError`</li><li>`Killed`</li></ul> | Make sure that your Docker environment has enough RAM allocated: [MacOS Instructions](http://stackoverflow.com/a/39720010), [Windows Instructions](https://docs.docker.com/docker-for-windows/#advanced)
After an update, you get: `django.contrib.auth.models.DoesNotExist: Permission matching query does not exist.` | Try to remove your WebODM folder and start from a fresh git clone
Task fails with `Process exited with code null`, no task console output | If the computer running node-opendronemap is using an old or 32bit CPU, you need to compile [OpenDroneMap](https://github.com/OpenDroneMap/OpenDroneMap) from sources and setup node-opendronemap natively. You cannot use docker. Docker images work with CPUs with 64-bit extensions, MMX, SSE, SSE2, SSE3 and SSSE3 instruction set support or higher.
Cannot access WebODM using Microsoft Edge on Windows 10 | Try to tweak your internet properties according to [these instructions](http://www.hanselman.com/blog/FixedMicrosoftEdgeCantSeeOrOpenVirtualBoxhostedLocalWebSites.aspx)
Getting a `No space left on device` error, but hard drive has enough space left | Docker on Windows by default will allocate only 20GB of space to the default docker-machine. You need to increase that amount. See [this link](http://support.divio.com/local-development/docker/managing-disk-space-in-your-docker-vm) and [this link](https://www.howtogeek.com/124622/how-to-enlarge-a-virtual-machines-disk-in-virtualbox-or-vmware/)
WebODM can be linked to one or more processing nodes running [node-OpenDroneMap](https://github.com/OpenDroneMap/node-OpenDroneMap). The default configuration already includes a "node-odm-1" processing node which runs on the same machine as WebODM, just to help you get started. As you become more familiar with WebODM, you might want to install processing nodes on separate machines.
Adding more processing nodes will allow you to run multiple jobs in parallel.
You **will not be able to distribute a single job across multiple processing nodes**. We are actively working to bring this feature to reality, but we're not there yet.
If you want to run WebODM in production, make sure to disable the `DEBUG` flag from `webodm/settings.py` and go through the [Django Deployment Checklist](https://docs.djangoproject.com/en/1.10/howto/deployment/checklist/).
When using Docker, all processing results are stored in a docker volume and are not available on the host filesystem. If you want to store your files on the host filesystem instead of a docker volume, you need to change a line in `docker-compose.yml` as follows:
From:
```
volumes:
- appmedia:/webodm/app/media
```
To:
```
volumes:
- /path/where/to/store/files:/webodm/app/media
```
Then restart WebODM.
Note that existing task results will not be available after the change. Refer to the [Migrate Data Volumes](https://docs.docker.com/engine/tutorials/dockervolumes/#backup-restore-or-migrate-data-volumes) section of the Docker documentation for information on migrating existing task results.
If you wish to run the docker version with auto start/monitoring/stop, etc, as a systemd style Linux Service, a systemd unit file is included in the service folder of the repo.
* Required WebODM directory checked out to /opt/WebODM
* Requires that /opt/WebODM is recursively owned by odm:odm
If all pre-requisites have been met, and repository is checked out to /opt/WebODM folder, then you can use the following steps to enable and manage the service:
First, to install the service, and enable the service to run at startup from now on:
From psql or [pgadmin](https://www.pgadmin.org), connect to PostgreSQL, create a new database (name it `webodm_dev`), connect to it and set the [postgis.enable_outdb_rasters](http://postgis.net/docs/manual-2.2/postgis_enable_outdb_rasters.html) and [postgis.gdal_enabled_drivers](http://postgis.net/docs/postgis_gdal_enabled_drivers.html) settings:
The `start.sh` script will use Django's built-in server if you pass the `--no-gunicorn` parameter. This is good for testing, but bad for production.
In production, if you have nginx installed, modify the configuration file in `nginx/nginx.conf` to match your system's configuration and just run `start.sh` without parameters.
Windows users should refer to [this guide](https://docs.djangoproject.com/en/1.11/howto/deployment/wsgi/modwsgi/) to install Apache + mod_wsgi and run gunicorn:
If you are getting a `rt_raster_gdal_warp: Could not create GDAL transformation object for output dataset creation`, make sure that your PostGIS installation has PROJ support:
You may also need to set the environment variable PROJSO to the .so or .dll projection library your PostGIS is using. This just needs to have the name of the file. So for example on Windows, you would in Control Panel -> System -> Environment Variables add a system variable called PROJSO and set it to libproj.dll (if you are using proj 4.6.1). You'll have to restart your PostgreSQL service/daemon after this change. [http://postgis.net/docs/manual-2.0/RT_ST_Transform.html](http://postgis.net/docs/manual-2.0/RT_ST_Transform.html)
If you are using Windows and are unable to go past the `pip install -r requirements.txt` command because of an error regarding zlib and Pillow, manually edit the `requirements.txt` file, remove the Pillow requirement and run:
```bash
easy_install pillow
pip install -r requirements.txt
```
On Windows make sure that all of your PATH environment variables are set properly. These commands:
The [OpenDroneMap project](https://github.com/OpenDroneMap/) is composed of several components.
- [OpenDroneMap](https://github.com/OpenDroneMap/OpenDroneMap) is a command line toolkit that processes aerial images. Users comfortable with the command line are probably OK using this component alone.
- [node-OpenDroneMap](https://github.com/OpenDroneMap/node-OpenDroneMap) is a lightweight interface and API (Application Program Interface) built directly on top of [OpenDroneMap](https://github.com/OpenDroneMap/OpenDroneMap). Users not comfortable with the command line can use this interface to process aerial images and developers can use the API to build applications. Features such as user authentication, map displays, etc. are not provided.
- [WebODM](https://github.com/OpenDroneMap/WebODM) adds more features such as user authentication, map displays, 3D displays, a higher level API and the ability to orchestrate multiple processing nodes (run jobs in parallel). Processing nodes are simply servers running [node-OpenDroneMap](https://github.com/OpenDroneMap/node-OpenDroneMap).
In general, follow these guidelines to find out what you should use:
I am a... | Best choice
--------- | -----------
End user, I'm not really comfortable with the command line | [WebODM](https://github.com/OpenDroneMap/WebODM)
End user, I like shell commands, I need to process images for myself. I use other software to display processing results | [OpenDroneMap](https://github.com/OpenDroneMap/OpenDroneMap)
End user, I can work with the command line, but I'd rather not. I use other software to display processing results | [node-OpenDroneMap](https://github.com/OpenDroneMap/node-OpenDroneMap)
Developer, I'm looking to build an app that displays map results and takes care of things like permissions | [WebODM](https://github.com/OpenDroneMap/WebODM)
Developer, I'm looking to build an app that will stay behind a firewall and just needs raw results | [node-OpenDroneMap](https://github.com/OpenDroneMap/node-OpenDroneMap)
-`Project`: A collection of tasks (successfully processed, failed, waiting to be executed, etc.)
-`Task`: A collection of input aerial images and an optional set of output results derived from the images, including an orthophoto, a georeferenced model and a textured model. A `Task`'s output is processed by OpenDroneMap.
-`ProcessingNode`: An instance usually running on a separate VM, or on a separate machine which accepts aerial images, runs OpenDroneMap and returns the processed results (orthophoto, georeferenced model, etc.). Each node communicates with WebODM via a lightweight API such as [node-OpenDroneMap](https://www.github.com/pierotofy/node-OpenDroneMap). WebODM manages the distribution of `Task` to different `ProcessingNode` instances.
We also have a [Gitter Chat](https://gitter.im/OpenDroneMap/web-development), but the preferred way to communicate is via the [OpenDroneMap Community Forum](http://community.opendronemap.org/c/webodm).
