WebIn the geometry column the values are in UTM. I have identified the sector as 44Q and I can use utm to extract the lat/long for a single value. I'm pretty new to using Geopandas but was hoping there was an .apply where I could duplicate and convert the linestring objects into a list of tuples and store them in another column. WebIn this situation, you have to set the CRS so geopandas knows how to interpret the coordinates. For example, if you convert a spreadsheet of latitudes and longitudes into a GeoSeries by hand, you would set the projection by passing the WGS84 latitude-longitude CRS to the GeoSeries.set_crs() method (or by setting the GeoSeries.crs attribute): tandermenovi na hrvatskom
