Has anybody worked with geopandas testing module?

I have two data sets with point data in ‘lat’ and ‘lon’ columns. A set of points of interest were mapped by two different people at two different points in time and I want to check their consistency. Thus, many of the points in the first data set correspond (approximately within a few meters) to a point in the second data set. Visually for a small sample that’s easy enough to do by plotting them on top of each other, but with several hundred points, I need a spatial merge. I found the sjoin_nearest method in geopandas.

New to Geo pandas.
