User: Write me two python classes - "Area" and "AreaDf".

Area represents one area/polygon. The class should allow querying it in multiple forms - list of vertices, geojson polygon, geopandas polygon, tile (orekit java class), get the area and accordingly transform between  these forms. Set operations with other area should also be possible.

The AreaDf is based on geopandas, plotting etc and is basically a set of area objects, but also with full dataframe capabilities to have other data etc. A proper geodataframe

Ask me if any more information will help
Assistant: Creating classes like `Area` and `AreaDf` to handle geographic areas effectively involves integrating both geometric manipulation and spatial data handling capabilities. Here’s a simplified version of these classes using Python with libraries such as `shapely`, `geopandas`, and some basic support for conversions:  

    from shapely.geometry import Polygon, mappingimport geopandas as gpdimport jsonclass Area:    def init(self, vertices):        self.vertices = vertices        self.polygon = Polygon(vertices)    def get_vertices(self):        return list(self.polygon.exterior.coords)    def to_geojson(self):        return mapping(self.polygon)    def to_geopandas(self):        return gpd.GeoSeries([self.polygon])    def area(self):        return self.polygon.area    def intersection(self, other):        return Area(list(self.polygon.intersection(other.polygon).exterior.coords))    def union(self, other):        return Area(list(self.polygon.union(other.polygon).exterior.coords))    def difference(self, other):        return Area(list(self.polygon.difference(other.polygon).exterior.coords))    @staticmethod    def from_geojson(geojson):        polygon = Polygon(geojson[‘coordinates’][0])        return Area(list(polygon.exterior.coords))    def repr(self):        return f"Area(vertices={self.get_vertices()})"class AreaDf:    def init(self, area_list):        self.areas = area_list        self.gdf = gpd.GeoDataFrame({‘geometry’: [area.polygon for area in area_list]})    def plot(self, **kwargs):        self.gdf.plot(**kwargs)    def get_areas(self):        return self.areas    def add_area(self, area):        self.areas.append(area)        self.gdf = self.gdf.append({‘geometry’: area.polygon}, ignore_index=True)    def getitem(self, key):        return self.gdf[key]    def setitem(self, key, value):        self.gdf[key] = value    def repr(self):        return self.gdf.repr()# Usage Example:if name == “main”:    # Create an area using a list of vertices    area1 = Area([(0, 0), (1, 0), (1, 1), (0, 1)])    area2 = Area([(0.5, 0.5), (1.5, 0.5), (1.5, 1.5), (0.5, 1.5)])        # Transformations    print(“Vertices:”, area1.get_vertices())
User: please format the code
Assistant: Certainly! Here’s the formatted code for the `Area` and `AreaDf` classes:  

    from shapely.geometry import Polygon, mappingimport geopandas as gpdclass Area:    def init(self, vertices):        self.vertices = vertices        self.polygon = Polygon(vertices)    def get_vertices(self):        return list(self.polygon.exterior.coords)    def to_geojson(self):        return mapping(self.polygon)    def to_geopandas(self):        return gpd.GeoSeries([self.polygon])    def area(self):        return self.polygon.area    def intersection(self, other):        return Area(list(self.polygon.intersection(other.polygon).exterior.coords))    def union(self, other):        return Area(list(self.polygon.union(other.polygon).exterior.coords))    def difference(self, other):        return Area(list(self.polygon.difference(other.polygon).exterior.coords))    @staticmethod    def from_geojson(geojson):        polygon = Polygon(geojson[‘coordinates’][0])        return Area(list(polygon.exterior.coords))        def repr(self):        return f"Area(vertices={self.get_vertices()})"class AreaDf:    def init(self, area_list=None):        if area_list is None:            area_list = []        self.areas = area_list        self.gdf = gpd.GeoDataFrame({‘geometry’: [area.polygon for area in area_list]})    def plot(self, **kwargs):        return self.gdf.plot(**kwargs)    def get_areas(self):        return self.areas    def add_area(self, area):        self.areas.append(area)        new_row = gpd.GeoDataFrame({‘geometry’: [area.polygon]})        self.gdf = pd.concat([self.gdf, new_row], ignore_index=True)    def getitem(self, key):        return self.gdf[key]    def setitem(self, key, value):        self.gdf[key] = value    def repr(self):        return self.gdf.repr()# Usage Example:if name == “main”:    # Create an area using a list of vertices    area1 = Area([(0, 0), (1, 0), (1, 1), (0, 1)])    area2 = Area([(0.5, 0.5), (1.5, 0.5), (1.5, 1.5), (0.5, 1.5)])    # Transformations    print(“Vertices:”, area1.get_vertices())    print(“GeoJSON:”, area1.to_geojson())    print(“Area:”, area1.area())    # Set Operations    intersection_area = area1.intersection(area2)    print(“Intersection Area Vertices:”, intersection_area.get_vertices())    union_area = area1.union(area2)    print(“Union Area Vertices:”, union_area.get_vertices())    # Create AreaDf    area_df = AreaDf([area1, area2])    area_df.plot()

  
  
This code defines two classes, `Area` for individual polygons and `AreaDf` for a collection of these polygons within a GeoDataFrame. It provides methods for geometric transformations and basic operations. Make sure to have the necessary libraries installed (`shapely`, `geopandas`, and `pandas`) to use this code effectively.
User: format it with ```python and indent properly
