EOmaps - Interactive maps in python!

EOmaps is a Python package to visualize and analyze geographical datasets.

It is built on top of matplotlib and cartopy and aims to provide an intuitive and easy-to-use interface to handle the following tasks:

• Speed up and simplify the creation and comparison of maps
• Visualize small datasets as well as millions of datapoints
• Handle 1D and 2D datasets and create plots from NetCDF, GeoTIFF or CSV files
• Take care of re-projecting the data
• Compare or overlay different plot-layers and WebMap services
• Use the maps as interactive data-analysis widgets (e.g. execute functions if you click on the map)
• Provide a versatile set of tools to customize the maps
• Arrange multiple maps in one figure
• Get a nice colorbar with a histogram on top
• Export high resolution images

🔨 Installation

To install EOmaps (and all its dependencies) via the conda package-manager, simply use:

conda install -c conda-forge eomaps

... to get a huge speedup, use mamba to solve the dependencies!

conda install -c conda-forge mamba
mamba install -c conda-forge eomaps

🌳 Basic usage

Checkout the 🚀 Basics in the documentation!

from eomaps import Maps

# initialize Maps object
m = Maps(crs=Maps.CRS.Orthographic())

# add map-features from NaturalEarth
m.add_feature.preset.coastline()
m.add_feature.cultural_50m.admin_0_countries(fc="none", ec="g")

# assign a dataset
m.set_data(data=[1, 2, 3, 4], x=[45, 46, 47, 42], y=[23, 24, 25, 26], crs=4326)
# set the shape you want to use to represent the data-points
m.set_shape.geod_circles(radius=10000) # (e.g. geodetic circles with 10km radius)
# (optionally) classify the data
m.set_classify_specs(scheme=Maps.CLASSIFIERS.Quantiles, k=5)
# plot the data
m.plot_map(cmap="viridis", vmin=2, vmax=4)
# add a colorbar with a colored histogram on top
m.add_colorbar(histbins=200)

# add a scalebar
m.add_scalebar()
# add a compass (or north-arrow)
m.add_compass()

# add imagery from a open-access WebMap services
m.add_wms.OpenStreetMap.add_layer.default()

# use callback functions to interact with the map
m.cb.pick.attach.annotate()

# use multiple layers to compare and analyze different datasets
m3 = m.new_layer(layer="layer 2")
m3.add_feature.preset.ocean()

# attach a callback to peek on layer 1 if you click on the map
m.cb.click.attach.peek_layer(layer="layer 2", how=0.4)
# attach a callback to show an annotation while you move the mouse
# (and simultaneously press "a" on the keyboard)
m.cb.move.attach.annotate(modifier="a")
# attach callbacks to switch between the layers with the keyboard
m.cb.keypress.attach.switch_layer(layer=0, key="0")
m.cb.keypress.attach.switch_layer(layer="layer 2", key="1")

# get a clickable widget to switch between the available plot-layers
m.util.layer_selector()

# add zoomed-in "inset-maps" to highlight areas on th map
m_inset = m.new_inset_map((10, 45))
m_inset.add_feature.preset.coastline(fc="g")

# ---- plot data directly from GeoTIFF / NetCDF or CSV files
m4 = m.new_layer_from_file.GeoTIFF(...)
m4 = m.new_layer_from_file.NetCDF(...)
m4 = m.new_layer_from_file.CSV(...)
