Classify roads and features in satellite imagery, by training neural networks with OpenStreetMap (OSM) data.
DeepOSM can:
- Download a chunk of satellite imagery
- Download OSM data that shows roads/features for that area
- Generate training and evaluation data
- Display predictions of mis-registered roads in OSM data, or display raw predictions of ON/OFF
Running the code is as easy as install Docker, make dev, and run a script.
Contributions are welcome. Open an issue if you want to discuss something to do, or email me.
By default, DeepOSM will analyze about 200 sq. km of area in Delaware. DeepOSM will
- predict if the center 9px of a 64px tile contains road.
- use the infrared (IR) band and RGB bands.
- be 75-80% accurate overall, training only for a minute or so.
- use a single fully-connected relu layer in TensorFlow.
- render, as JPEGs, "false positive" predictions in the OSM data - i.e. where OSM lists a road, but DeepOSM thinks there isn't one.
For training data, DeepOSM cuts tiles out of NAIP images, which provide 1-meter-per-pixel resolution, with RGB+infrared data bands.
For training labels, DeepOSM uses PBF extracts of OSM data, which contain features/ways in binary format that can be munged with Python.
The NAIPs come from a requester pays bucket on S3 set up by Mapbox, and the OSM extracts come from geofabrik.
DeepOSM has been run successfully on both Mac (10.x) and Linux (14.04 and 16.04). You need at least 4GB of memory.
You need AWS credentials to download NAIPs from an S3 requester-pays bucket. This only costs a few cents for a bunch of images, but you need a credit card on file.
-
get your AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY from AWS
-
export them as environment variables (and maybe add to your bash or zprofile)
export AWS_ACCESS_KEY_ID='FOO'
export AWS_SECRET_ACCESS_KEY='BAR'
First, install a Docker Binary.
I also needed to set my VirtualBox default memory to 4GB, when running on a Mac. This is easy:
- start Docker, per the install instructions
- stop Docker
- open VirtualBox, and increase the memory of the VM Docker made
In order to use your GPU to accelerate DeepOSM, you will need to
download and install the latest NVIDIA drivers for your GPU, and
(after first installing docker itself), install nvidia-docker
.
First, find the latest NVIDIA drivers for your GPU on NVIDIA's website. Make sure you check the version number of the driver, as the most recent release isn't always the latest version.
Once you have downloaded the appropriate NVIDIA-*.run
file, install
it as follows (based on
these instructions):
Ensure your system is up-to-date and reboot to ensure the latest installed kernel is loaded:
# ensure your packages are up-to-date
sudo apt-get update
sudo apt-get dist-upgrade
# and reboot
sudo reboot
Once your system has rebooted, install build-essential
and the
linux-headers
package for your current kernel version (or
equivalents for your linux distribution):
sudo apt-get install build-essential linux-headers-$(uname -r)
Then run the NVIDIA driver install you downloaded earlier, and reboot your machine afterwards:
sudo bash <location of ./NVIDIA-Linux-*.run file>
sudo reboot
Finally, verify that the NVIDIA drivers are installed correctly, and
your GPU can be located using nvidia-smi
:
nvidia-smi

Now that the NVIDIA drivers are installed, nvidia-docker
can be
downloaded and installed as follows (based on
these instructions):
wget -P /tmp https://github.com/NVIDIA/nvidia-docker/releases/download/v1.0.1/nvidia-docker_1.0.1-1_amd64.deb
sudo dpkg -i /tmp/nvidia-docker*.deb && rm /tmp/nvidia-docker*.deb
And you can confirm the installation, by attempting to run nvida-smi
inside of a docker container:
nvidia-docker run --rm nvidia/cuda nvidia-smi

Once you have confirmed nvidia-smi
works inside of nvidia-docker
,
you should be able to run DeepOSM using your GPU.
Start Docker, then run:
make dev-gpu
Or if you don't have a capable GPU, run:
make dev
Inside Docker, the following Python scripts will work. This will download all source data, tile it into training/test data and labels, train the neural net, and generate image and text output.
The default data is six NAIPs, which get tiled into 64x64x4 bands of data (RGB-IR bands). The training labels derive from PBF files that overlap the NAIPs.
python bin/create_training_data.py
python bin/train_neural_net.py
For output, DeepOSM will produce some console logs, and then JPEGs of the ways, labels, and predictions overlaid on the tiff.
There is a very limited test suite available at the moment, that can be accessed (from the host system) by running:
make test
Alternately, development/research can be done via jupyter notebooks:
make notebook
To access the notebook via a browser on your host machine, find the IP VirtualBox is giving your default docker container by running:
docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
default * virtualbox Running tcp://192.168.99.100:2376 v1.10.3
The notebook server is accessible via port 8888, so in this case you'd go to: http://192.168.99.100:8888

This was the general idea to start, and working with TMS tiles sort of worked (see first 50 or so commits), so DeepOSM got switched to better data:
