Distance calculated in different software (MapInfo and QGIS) has given me differences in distance values. To be more precise, it's mostly happening when the distance is more than 25 miles. I doubt this is because QGIS is always including the earth curve (3D) while calculating distances, while in MapInfo, it's directly measuring the distances in 2D form. Why I am sure about 3D and 2D impact is because the distance I am getting is always huge in QGIS when compared.
If this is the case, how can we calculate the distances in MapInfo with the earth curve included in measurements and should come similar to QGIS?
