PyGeoPlot

A library for plotting data on the map.

Demo: Moscow CCTV cameras

Tutorial

Installing

To install PyGeoPlot just clone the repository and run setup.py.

$ git clone https://github.com/romovpa/pygeoplot.git
$ cd pygeoplot
$ python setup.py install

Creating map canvas

import pygeoplot as gp

m = gp.Map()

To see empty map in your Notebook say display():

m.display()

You can specify size of the map container and even make it resizeable (by dragging the lower right corner):

m.display(width=600, height=300, resizeable=True)

Drawing a line

points = [
    (55.864414, 37.401979),
    (55.575286, 37.635438),
    (55.845875, 37.801606),
    (55.665433, 37.426698),
    (55.685610, 37.830446),
    (55.864414, 37.401979),
]
m.add_line(line_points, color="#FF0000", width=10, opacity=0.6)

Setting zoom and the center point

center_point = (55.72, 37.64)
m.set_state(center_point, zoom=12)

Adding placemarks

m.add_placemark((55.702770, 37.529184),
                hint='Alma Mater', content='Moscow State University')
m.add_placemark((55.711552, 37.621861),
                hint='The Center of the pentagram')

The content could contain any valid HTML:

m.add_placemark((55.711552, 37.621861), hint='A Cat',
    content='<img width=300 height=200 src="http://www.findcatnames.com/wp-content/uploads/2014/09/453768-cats-cute.jpg" />')

Heatmap

You can visualize a set of geo-points with heatmap. The feature is implemented by using Yandex Maps API Heatmap Module.

points = [
    (55.864414, 37.401979),
    ...
]
m.add_heatmap(heatmap_points)

Moscow CCTV cameras demo contains an example of the heatmap of the real data.

Saving map to stand-alone HTML file

After completing your visualization, you could write it into stand-alone HTML file and share with colleagues.

m.save_html('map_with_data.html')

An example of exported HTML from CCTV demo: ipynb/demo-moscow-cctv-heatmap.html.

Further Work

Todo-list

• robust and clear javascript code base
• drawing polygons and circles
• changing locales

Wanna-list

• supporting different map engines Google Maps, Leaflet (OSM)
