kandi X-RAY | geoplot Summary
geoplot is a high-level Python geospatial plotting library. It's an extension to cartopy and matplotlib which makes mapping easy: like seaborn for geospatial. It comes with the following features:. Installation is simple with conda install geoplot -c conda-forge. See the documentation for help getting started. Author note: geoplot is currently in a maintenence state. I will continue to provide bugfixes and investigate user-reported issues on a best-effort basis, but do not expect to see any new library features anytime soon.

QUESTION
When I try to install geoplot in either my Linux box or windows box the terminal either gets hung up or I get an error: unable to determine GEOS version . I checked geos version in anaconda and it states I have GEOS 3.8.
I've tried both pip install geoplot
and the line provided on the conda-forge site for geoplot conda install -c conda-forge geoplotlib
.
I've searched for a solution for the past couple hours, but no avail.
...ANSWER
Answered 2021-Jul-28 at 04:14This is a frequent issue faced by most of the developers trying to install GEOS, Cartopy and Proj.
It happens to be that there are certain packages that need to exist before installing GEOS or Cartopy. A quick look at your screenshot of the error, you can try out the following...
QUESTION
I'm trying to use geoplot to draw a heatmap of crime distribution in San Francisco county. The problem is when I used the dataset from geoplot to draw the map of SF, the x,y axes do not appear. I'm using this map for my final presentation, so I figured it would be more readable for my audiences with axes displayed for them(longitude&latitude as axes). I've searched as many documents as I could, and I tried to use ax.axis('on') but didn't work. I would be much appreciate for any advice given. Thanks (BTW I'm doing this on jupyter) df is the data frame I used which contained 500k crime records with locations containing longitude & latitude.
...ANSWER
Answered 2021-Dec-09 at 11:16Geoplot is built on top of cartopy, and the returned axis objects do seem to be normal cartopy GeoAxis
objects, so you should be able to use any figure customizations available within that library. By default cartopy plots do not include axis ticks/ticklabels because the library is frequently used to plot in a projection, where the x and y values do not correspond to lat/lon.
To add gridlines in cartopy, use ax.gridlines
. These will correctly handle your projection and draw lat/lon lines as contours on your map.
From the docs on adding map gridlines and tick labels:

- these points are in Saudi Arabia, so assumed that polygons are regional boundaries in Saudi Arabia. Downloaded this from http://www.naturalearthdata.com/downloads/10m-cultural-vectors/

I got a dataframe with the following columns Name (string), size (num), latitude (num), longitude (num), geometry (shapely.geometry.point.Point).
When i'm plotting my points on a map and are trying to annotate each point the annotation is not shown at all. My guess is that this is due to the projection im using.

Answered 2021-Sep-08 at 03:45I'm commenting on a previous question: I've just run the example in the official geoplot reference with Colab and experienced a similar crash. After some research I found that the crash was caused by shaply and uninstalled and reinstalled it and the graphs were displayed as per the reference. Please give it a try.

QUESTION
I would like to figure out how to plot a geoplot onto subplots in matplotlib. i.e. I have plotted a GeoDataFrame with geometries, and a column of counts, but I would like multiple maps on a grid of subplots
Also if you know a way to use facetgrid with geoplots, that would be helpful.
...ANSWER
Answered 2020-Mar-24 at 18:10GeoPandas plot is a single matplotlib axis, you can use it like any other plots. Plotting four maps in a grid of subplots could look like this.
QUESTION
I am using geoplot which uses matplotlib to create plots.
One such functionality is geoplot.pointplot
, that creates an AxesSubplot
every time you call it. This allows you to call it multiple times and overlay a bunch of pointplot
s. The underlying code simply creates a matplotlib scatter
.
My problem is that for each of these pointplot
s, geoplot
assigns them an individually unique cmap
, and so if one plot is yellow at a value of 40
, another might be blue. This is an issue, as I don't want to have multiple legends for 1 plot. Ideally, all the plots follow a single legend and the values are consistent among the plots.
Below is an example:
Any help in solving this would be much appreciated. I tried feeding vmin
and vmax
to geoplot.pointplot
but they each had no affect.
EDIT:
I have found a "solution". By adding a point to each subplot at the south pole, it falls outside the bounds of the graph and as such artificially increases the range of the colorbar. I'm not answering with this, because this is a vry hacky way of getting what I want done, and not ideal. This is done through the following code:
...ANSWER
Answered 2020-Jan-16 at 05:12The 'proper' way to do this is by creating a matplotlib.cm.cmap
instance along with a matplotlib.colors.Normalize
and passing them in to geoplot.pointplot
via keyword arguments cmap
and norm
respectively. The colormap being used by the image in the question is viridis
, here is an example of creating and normalizing a viridis
cmap

Install geoplot
You can use geoplot like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
