PyBossa geo-demo project: Urban Parks in cities
This demo project shows how you can use PyBossa for geo-coding problems.
Thanks to the use of OpenLayers the data can be exported in any standard GIS format: KML, GeoJSON, etc. In this project the answers are saved as GeoJSON.
The project has five main files:
- project.json: a JSON file that describes the project.
- long_description.md: a Markdown file with a long description of the project.
- cities.csv: a CSV file that contains sample tasks to be used by the project.
- template.html: the view for every task and deal with the data of the answers.
- tutorial.html: a simple tutorial for the volunteers.
Testing the project:
You need to install pybossa-pbs. If you don't have a virtual environment, we recommend you to create one, and activate it:
$ virtualenv env $ source env/bin/activate
Then, you can install pybossa-pbs:
$ pip install pybossa-pbs
Or if you prefer:
$ pip install -r requirements.txt
Creating an account in a PyBossa server
Now that you've all the requirements installed in your system, you need a PyBossa account:
- Create an account in your PyBossa server (use Crowdcrafting if you want).
- Copy your API-KEY (you can find it in your profile page).
Configure pybossa-pbs command line
PyBossa-pbs command line tool can be configured with a config file in order to avoid typing the API-KEY and the server every time you want to take an action on your project. For this reason, we recommend you to actually create the config file. For creating the file, follow the next steps:
$ cd ~ $ editorofyourchoice .pybossa.cfg
That will create a file. Now paste the following:
[default] server: http://yourpybossaserver.com apikey: yourapikey
Save the file, and you are done! From now on, pybossa-pbs will always use the default section to run your commands.
Create the project
Now that we've everything in place, creating the project is as simple as running this command:
$ pbs create_project
Using a CSV file for adding tasks
Now we can add some tasks. The project comes with a sample tasks file in CSV format that you can use. The CSV file has two headers, question (for the question to be displayed to volunteers about the task) and city (with the name of the city and country it is located).
This is very simple too, thanks to pbs:
$ pbs add_tasks --tasks-file cities.csv
You'll get a progress bar with the tasks being uploaded. Now your project has some tasks in the server to be processed by the volunteers.
Finally, add the task presenter, tutorial and long description
Now that we've some data to process, let's add to our project the required templates to show a better description of our project, to present the tasks to our users, and a small tutorial for the volunteers:
$ pbs update_project
NOTE: we provide templates also for Bootstrap v2 in case your PyBossa server is using Bootstrap2 instead of Bootstrap3. See the rest of the files.
Please, see the COPYING file.
