Regarding projection system(crs) for graph generation #95

Open rockbusteriitk opened 9 months ago

rockbusteriitk commented 9 months ago

Hi,

I tried theEPSG:3857 Projection.

"from geograph import GeoGraph data= r'D:\Geograph\lulc_test\lulc_2021.tif' graph = GeoGraph(data,crs="EPSG:3857")"

and

"from geograph.visualisation.geoviewer import GeoGraphViewer viewer = GeoGraphViewer() viewer.add_graph(graph, name='my_graph')

viewer.enable_graph_controls()

viewer"

and I received the error: "AttributeError Traceback (most recent call last) Cell In[5], line 3 1 from geograph.visualisation.geoviewer import GeoGraphViewer 2 viewer = GeoGraphViewer() ----> 3 viewer.add_graph(graph, name='my_graph') 4 #viewer.enable_graph_controls() 5 viewer

AttributeError: 'super' object has no attribute 'append"

What might be the problem and is there a wayaround?

I'm also getting this error.

Looks like it's related to the append function being deprecated in pandas.

Similar issue: https://stackoverflow.com/questions/75956209/error-dataframe-object-has-no-attribute-append

Can get around it by updating functions similar to this: https://github.com/geopandas/geopandas/issues/2606
