Hi,

Is there any way to manually specify:

• coordinates for that will be located at the center of the image,
• zooming ratio,
• or maybe ROI?

For example, for the attached image it seems like a good idea to move the center higher to the North and zoom in.

And, by the way, thanks for the very cool tool!

This is a feature request.

Can we specify which direction is "up" on the map? I don't always want North to point upward.

I think it would be awesome if you integrated this with GeoPandas. It would make both packages more powerful. Haven't really looked under the hood, but if you're already working with dataframes I imagine it wouldn't be much of a stretch.

Dears,

I've install mapsplotlib and try to run the following,

However, got the following.

IOError: cannot identify image file <StringIO.StringIO instance

I believe it was due to Pillow module didn't recognize certain image format.

Kindly advise.

This is a feature request. Zooming in and out is essential to visualizing data on different scales. Is there a way to incorporate the same in mapsplotlib as well?

Using the variety of different plotting tools offered by your (very awesome, mind you) tool, I'm unable to see any details on the map whatsoever aside from the plots and very basic water features. Any idea what the cause may be? There's no output indicating that my inputs aren't correct.

While I was importing the library

from mapsplotlib import mapsplot as mplt

It prompts me the error

File "C:\ProgramData\Anaconda3\lib\site-packages\mapsplotlib\mapsplot.py", line 213
print '[WARN] Cannot draw polygon for cluster {} - only {} samples.'.format(c, in_polygon.sum())

SyntaxError: invalid syntax

Please advise what to do

Hello Thomas,

Thanks for the great package. It helps me a lot. I just want to know whether I can increase the colour intensities in the heatmap function. I could not find a parameter to do that. Appreciate your help. Cheers!

Hi tcassou,

Thank you very much for the work!

I am new to Python. I invoke mplt.scatter function in a for loop, each time inputting with the corresponding row of my dataframe. 2 problems I encounter so far:

1. When I pass the dataframe's ith row in the for loop mplt.scatter(df_geo['latitude'][i],df_geo['longitude'][i]) it throws the following error "numpy.float64' object has no attribute 'index". I wanted to put ith dot on the map within the loop.

2. In the for loop, each time it creates a figure, how can I put it one of my subplots and update the map in the for loop.

Cheers,

#%matplotlib inline
import pandas as pd

from mapsplotlib import mapsplot as mplt

mplt.register_api_key('AIza*****************yJDcvyus')
df = pd.read_csv(r'C:\Users\leo_a\Daily_Learning\Thesis_Work\AoT_Chicago.complete.2018-08-08.from-2018-08-02-to-2018-08-08\nodes.csv')
df['latitude']=df['lat']
df['longitude']=df['lon']
new_df=df[['latitude', 'longitude']].copy()
mplt.plot_markers(new_df)

I am trying to mark in the df on gmap but the result of this is

I am not sure what I am doing something wrong , please guide

If the list of latitudes and longitudes passed to get_zoom has only one point, or they are all at the same point, the return value of this function goes to infinity, causing OverflowError: cannot convert float infinity to integer. This should be caught or prevented, and a maximum zoom value returned. OR: A more descriptive error should be raised.

Trying to replicate the example fails:

For some reason, using the heatmap function returns this error
'UnicodeDecodeError: 'ascii' codec can't decode byte 0x89 in position 0: ordinal not in range(128)'
, when the function worked fine a few days ago.

After doing some investigating, I was able to figure out with what I believe may have been the issue:

The GoogleStaticMapsAPI.map function uses one's api key to call an image of the map, which returns the 403 error. I was able to side step this issue by customizing my own version of the GoogleStaticMapsAPI.map function without appending api key to the end of the url.

Is this issue happening to other people too? How can one sidestep this problem?

Heya,
You have polygons, but I was surprised to see you don't support Polylines.
Would this be a feature worth adding?
Thanks.
