we are going to use Aspose.GIS in our project, but for us very important transformation accuracy. We tried a few versions and have the next results:
(3399381.0, 6487595.0) v18.12.1
(3399381.0, 6520551.0) v20.3
transformation with qgis:
transformation with epsg:
looks like you improve accuracy, but could we get transformation result without rounding to the nearest digit?
P.S. we transform (30.5371609, 50.4269714) from EPSG 4326 to EPSG 3857
