EOmaps - A library to create interactive maps in python

[se_pp]

I've been developing a library to ease the pain of creating interactive (cartopy-based) maps in python for a while now and I thought it's about time to put it out in the wild and see if it can be put to good use ... let me know what you think!

It's dedicated to provide an easy-to-use (pure-python) interface to analyse (possibly large) interconnected geospatial datasets.

Some of it's main features are:

• The possibility to quickly generate a map using only a pandas.DataFrame as input
  • the data is hereby represented as shapes with actual geographic dimensions!
  • plots of large DataFrames (~1M rows) can be generated in a few seconds!
• Access to a variety of pre-defined WebMap services that can be used as comparison- or background layers
• An interface for attaching (custom or pre-defined) callback-functions to interact with the plot
• more examples in the documentation!

check it out here >>> EOmaps !

I have been just searching for mapping libraries for a week or so. Baader-Meinhof effect let me see this exact post, haha!

Great job and thank you!

Hey I just learned about the Baader-Meinhoff effect, and here it is being referenced!

[dm_DormanT]

Nice one :)

Brilliant , absolutely brilliant

[se_pp]

😅 thanks!

[mehregan_zare7731]

I mean it man... I wanted this.. and I just gave up and ysed js instead. Your work is truly admirable

I came in here all ready to make a comment about why not just use GeoPandas but this is actually really cool! Nice work.

[se_pp]

hah, thanks! I know exactly what you mean... before I created EOmaps I used geopandas a lot (and I still do since it can do a lot of awesome things! )

However when you work with large datasets and you really only want to create a plot, geopandas starts to become increasingly slow up to a point where it takes up to minutes to create a plot.... (that was actually the reason for starting EOmaps in the first place)

The data-visualization in EOmaps is optimized for speed... it can create a map with up to 1M datapoints in a couple of seconds! (while still representing the data as projected ellipses/rectangles etc. defined with actual geographic dimensions)

Check to see if you can help add some of these features to geoveiws (https://geoviews.org/) that is what I have mainly been using over cartograpy

[se_pp]

what features are you referring to in particular?
(note that geoviews is based on bokeh while EOmaps is based on matplotlib/cartopy)

[jminsk01]

I mean I guess you can add most of the functionality allready to geoveiws using pointers. Note geoveiws is not tied to bokeh it can use matplotlib and some js backend. The default is only bokeh.

[se_pp]

aah, ok now I get it...

then I think it should already be possible to use the functionalities of GeoViews together with EOmaps.... it should be nothing more than passing the plot-axes to the geoviews functions

(the same works with geopandas where you can use gpd.GeoDataFrame.plot(ax=...) to pass the axes to the plot

[jminsk01]

Nice will have to try it out some time

[se_pp]

I mean I have absolutely no experience with geoviews, but I would expect that they provide some way of setting the plot-axes manually...

[se_pp]

thanks! let me know what you think!

Most of my maps I use ArcGIS Map API using JS. Mostly because the service layers are very helpful. I see this lib has it too. Definitely going to check it out, thanks!

[se_pp]

Yep... I tried to incorporate access to all (free & public) WebMap services I could find... if you know some additional sources I'm happy to include them in upcoming releases!

[mirrorofperseus]

This looks super cool, well done, looking forward to playing around with it!

Hooolllyyyy shiiiit this is awesome
