OSM Mapping Tool

This command line mapping tool provides functionality to download and display OSM data via Geopandas Pyplot (static) or Bokeh (interactive). Running this tool thus yields a map of the given search area and specified OSM tag filters. The result will pop up (plotly) or will be displayed in the standard browser of your system. It can be saved automatically or via the GUI.

Example Plots with gpd and bokeh and the given input example parameters.

Map Examples

Bokeh example:

Geopandas Plotly example:

Setting up:

• installed version of Python 3.9
• fork and clone this repository
• create new environment via pip or conda (recommended)
• activate environment and use given requirements.txt/environment.yml files to install dependencies respectively.

To run the program from the command line:

• activate the corresponding virtual environment
• change directory to .\src\ and execute pip install --editable . now mapping_tool is ready to be used as command in the command line when you switch back to mapping_tool roots directory.

Required Input files

This tool requires some input data which has to be put in the Input folder with the given names and structure as in the example files. Example data and file structure is given. Modify content but not file names or structure if different input is wanted. It is not possible to add more paramters through the files then the ones listed.

• input_download.json: Specify name, filter, time and name of the boundary polygon as input for each layer
• input_polygon.geojson: Polygon of the area of interest.
• input_bokeh.json: Specify parameters for plotting with bokeh. Name and color. Name has to be the name of the input file (the same as in the download parameters)
• input_gpd.json: Specify parameters for plotting with Pyplot. Name and color. Name has to be the name of the input file (the same as in the download parameters)

How to run the tool

The folder to execute this programm has to be the root folder of the repository (mappint_tool)! Executing commands without specifying any parameters will use default parameters only.

  -rb, --random_baselayer BOOLEAN
                                  If True, creates four bokeh plots with the
                                  given layers and randomly chosen basemaps.

  --help                          Show this message and exit.

Example

mapping_tool run-plotting --plotting_package bokeh --save_plot True --basemap Stamen.Watercolor --title waterColorHeidelberg

or

mapping_tool run-plot --plot_package gpd --save_plot True --basemap Stamen.TonerLite --title StamenTonerLiteHeidelberg

Both these commands will execute plotting and save a PNG to the ./data/output folder. The bokeh example will also save an interactive .html with the same name to the same location.
