Dear all,<br><br>A few weeks ago, I posted a question regarding a custom projection.<br><br>I wanted to transform from a known CRS (ECEF or WGS84) into a custom projection. Martin helped me a lot, telling me how to construct the ProjectedCRS.<br><br>He also mentionned about the MathTransform (which is what I currently need). I just don't understand a few things : I guess the MathTransform needs to know the source AND the target CRS, am I wrong ? Because, on the previous post, Martin only told about defining a source CRS...<br><br>Is it a way to create a math transform (MathTransformFactory?) knowing the (maybe custom) source CRS and the (maybe custom as well) target CRS ?<br><br>Thank you in advance for your help,<br><br>Sam<br> <br /><hr />Vous souhaitez de connecter votre club et coéquipiers en ligne?
