Geospatial View Static

This node will visualize the given geometric elements using the matplotlib. It can be used to create Choropleth Maps by assigning a marker color column. The node further supports various settings to adapt the legend to your needs. For more information on the settings, please refer to the geopandas.GeoDataFrame.plot.

Options

Geometry column

Select the geometry column to visualize.

Line width column

Select line width column. The width is fixed by default. If a line width column is selected, the width will be scaled by the values of the column.

Line width

Select a unified line width, can be set to none.

Figure title

Set the title of the figure.

Figure title size

Set the size of the figure title.

Set axis off

If checked, the axis will be set off.

Image output type

Select the type of output image.

Available options:

  • SVG: Scalable support vector graphic (SVG) best suited for PDF reports.
  • PNG: PNG image best suited for presentations.

Size Settings

Group of settings that define the size of the geometric objects. The size column should be numerical. The size is fixed by default. If the 'Marker size column' is selected, the 'Marker size scale' option will be ignored, and size will be scaled by the values of the column. For point features, the size is the radius of the circle. For line features, the size is the width of the line. For polygon features, the size is the radius of the centroid of the polygon.

Marker size column

Select marker size column.

Marker size scale

Select the size scale of the markers. If the Marker size column is selected, this option will be ignored. Noticed that the size scale only works for point features.

Coloring Settings

Group of settings that define the coloring of the geometric objects. The color column can be either nominal or numerical. If a numerical column is selected you might want to enable the classification of the numeric values to group them into bins prior to assigning a color to each bin using the color map information. If a nominal column is selected the color map will be used to assign a color to each unique value in the column. Noticed that if a nominal column is selected the classification settings will be ignored.

Marker color column

Select marker color column to be plotted. If numerical you might want to adapt the classification settings accordingly. If nominal the color map will be used to assign a color to each unique value in the column. Noticed that if a nominal column is selected the classification settings will be ignored. Select 'None' if you want a unified marker color.

Marker color

Select marker color. It will assign a unified color for all features. If a 'Marker color column' is selected, this option will be ignored. Select none if you don't want to set a unified marker color.

Color map

Select the color map to use for the color column. See Colormaps in Matplotlib.

Classify numerical marker color columns

If checked, the numerical marker color column will be classified using the selected classification method. The 'Number of classes' will be used to determine the number of bins.

Classification method

Select the classification method to use for the selected numerical marker color column.

Number of classes

Select the number of classes used by the classification method.

Edge color

Set the edge color. See Colormaps in Matplotlib.

Color Legend Settings

Group of settings that define if a color legend is shown on the map and if so how it should be formatted. The color legend is only shown if you have selected a color column. More details about the legend settings can be found matplotlib.pyplot.legend and matplotlib.pyplot.colorbar.

Show color legend

If checked, the color legend will be shown in the plot.

Legend caption

Set the caption for the legend. By default, the caption is the name of the selected color column or empty for heat map.

Caption font size

Set the font size for the legend caption.

Expand legend

If checked, the legend will be horizontally expanded to fill the axes area.

Legend location

Select the location for the legend.

Legend columns

Select the number of columns for the legend.

Legend size

Select the size for the legend.

Legend font size

Select the font size for the legend.

Legend label color

Select the label color for the legend.

Show legend frame

If checked, a frame will be shown in the legend.

Legend frame alpha

Select the transparent value for the legend frame.

Legend border pad

Select the border pad for the legend.

Legend label spacing

Select the label spacing for the legend.

Color bar legend shrink

Select the shrinking value for the color bar legend. Only works for color bar.

Color bar legend pad

Select the pad value for the color bar legend. Only works for color bar
