Which, as you remember, is a Bokeh-specific way of storing the data.įrom bokeh.palettes import RdPu9 from bokeh.models import LinearColorMapper, BasicTicker, ColorBar, Legend, LegendItem # instantiate a new colormapper, provide min and max values for the scale color_mapper_v = LinearColorMapper ( palette = RdPu9, low = grid_proj. Convert the DataFrame (without geometry column) into a ColumnDataSource
Yep, now we have the x and y columns in our GeoDataFrame. apply ( getLineCoords, geom = 'geometry', coord_type = 'y', axis = 1 ) # Let's see what we have now In : roads. apply ( getLineCoords, geom = 'geometry', coord_type = 'x', axis = 1 ) # Calculate y coordinates of the line In : roads = roads. # Calculate x coordinates of the line In : roads = roads. Which is a Bokeh-specific way of storing the data. Thus, we will convert our DataFrame into ColumnDataSource The third step, is to convert our DataFrame into a format that Bokeh can understand. Okey great! Now we have the x and y columns in our GeoDataFrame. head () Out: id name Aadress X y geometry x 0 13376 Aakre Lasteaed-Algkool Valga maakond, Puka vald, Aakre küla, Mõisa te. apply ( getPointCoords, geom = 'geometry', coord_type = 'y', axis = 1 ) # Let's see what we have now In : points.
apply ( getPointCoords, geom = 'geometry', coord_type = 'x', axis = 1 ) # Calculate y coordinates In : points = points. # Calculate x coordinates In : points = points. Where the first one should be a Shapely geometry object and coord_type should be either 'x' or 'y'. It shall have two parameters: geom and coord_type Thus, let’s create our own function called getPointCoords() which will return the x or y coordinate of a given geometry. Unfortunately there is not a ready made function in geopandas to do that. Now, as a second step, we need to calculate the x and y coordinates of those points.

Okey, so we have several columns plus the geometry column as attributes. head () Out: id name Aadress X y geometry 0 13376 Aakre Lasteaed-Algkool Valga maakond, Puka vald, Aakre küla, Mõisa te.
