I have a shapefile of points, defined by X and Y coordinates, ad the ID feature. I have at least 3 different points with the same ID number. I would like to define, for each ID, the shapefile of a circle that circumscribes the points. How can this be done in python environment? Answer there is a library that does

Switching off all Folium tiles
I’m wondering if it’s possible to switch off all Folium tiles that have been added to a Folium Map object. By default one tile should be selected, but could be displayed a blank background? It’s an option that I thinkg could be useful to enhance the visualization of the entities that have been laid over the tiles. Answer you can
When do I need to use a GeoSeries when creating a GeoDataFrame, and when is a list enough?
I define a polygon: and create a list of random points: I want to know which points are within the polygon. I create a GeoDataFrame with a column called points, by first converting the points list to GeoSeries: Then simply do: which returns a pandas.core.series.Series of booleans, indicating which points are within the polygon. However, if I don’t create the
geopandas midpoint on line
I have a geopandas dataframe of linestrings. Each line string is a single line. I want to get the midpoint of the line and append the point geometry to geodataframe in a column centroid. How do I achieve this? Answer LineString has a centroid, hence case of using it solution demonstrates this with output as visual and as data geometry
Converting a list of coordinates to point geometry
My geopandas df looks like this: As you can see, the geometry column is a list containing longitude and latitude values. Is there an efficient way to convert them to points? This works but is very inefficient: When I put this in a loop I get TypeError: len() of unsized object Basically I need the inverse of this question. Reproducible
Is overlay how=’difference’ supposed to operate differently from geopandas 0.9 vs 0.10?
I was using the difference set operation for a different problem, but I would get an empty geodataframe or None type when replacing a polygon with the difference in my geodataframe. I found it to be a result of having non-intersecting polygons and doing the difference set-operation. I was wondering is this normal behavior or should it still be keeping
Converting Geojson information to geopandas geometry
I have geojson file like this: I would like to extract the polygon information and save as polygon geometry in a geopandas data frame. I’m having trouble converting extracting this information from the geojson I would appreciate if anyone can help Answer you can construct valid geojson from you dict snippet your coordinates are too deep hence taking zeroth element
geopandas known intersection returns False
I have two sets of multipolygons. I want to select one polygon from one dataset (by using the matplotlib click event which works) and then select all polygons from the second dataset that intersect with it. When I plot the datasets they clearly overlap (see below) but my intersection always returns False. The datasets look like this: I select one
Using Geopandas on python to create an interactive map
I’m trying to create an interactive map using this guide: This I use pycharm with anaconda environment, so I don’t understand when put my .shp file. This is the example code: Is this correct my directory? Error: Thank you in advance. Giovanni Answer You seem to have a n in your path, which is interpreted as a newline character. (Note
Extract values from xarray dataset using geopandas multilinestring
I have a few hundred geopandas multilinestrings that trace along an object of interest (one line each week over a few years tracing the Gulf Stream) and I want to use those lines to extract values from a few other xarray datasets to know sea surface temperature, chlorophyll-a, and other variables along this path each week. I’m unsure though how
