I have points in Harrisburg, PA in a GeoPandas (Python) GeoDataFrame with no CRS.

How do I convert them to WGS84?

I'm trying to do something like below but don't know what CRS to initially set the GeoDataFrame to.

my_points.set_crs('<what do I put here?>').to_crs('epsg:4326')

Here is what my_points looks like:

                           geometry
0    POINT (2243939.780 360357.900)
1    POINT (2257434.260 344832.350)
2    POINT (2236659.870 371819.840)
3    POINT (2245296.700 332006.600)
4    POINT (2251921.980 340172.260)

The coordinates I have are in feet, in the coordinate system NAD83 / Pennsylvania South (ft US). The EPSG code for it is EPSG:2272. I found that out by trying the epsg code of a data set I have for the same region, though the link in the answer by Joe Be would certainly have gotten be there:

Identifying Coordinate System of Shapefile when Unknown? .

To convert it to WGS84 with Python GeoPandas was:

my_points.set_crs('epsg:2272').to_crs('epsg:4326')
