A) projection What is the difference between Lat/Long and Web Mercator (georeference.org) and sub link https://manifold.net/doc/mfd9/example__reproject_a_drawing.htm i expect to be able to have access to the editor when click on item list in standard and EPSG tab but not , why even i only want to see text list in a form ( write mode disable) . i think all projection must use a value for thoses variables : { "Name": "WGS 84 \/ NSIDC EASE-Grid 2.0 Global (EPSG:6933)", "System": "Lambert Cylindrical Equal Area", "CenterLat": 30, "CenterLon": 0, "Axes": "XY", "Base": "WGS 84 (EPSG:4326)", "MajorAxis": 6378137, "Eccentricity": 0.08181919084262149, "Unit": "Meter", "UnitScale": 1, "UnitShort": "m" } Does the 2 projections below are the same except metric ? Why not make viewable the Coordinate System Metrics explicitly ( even if 0) by using Label ? but which of those items are relative to Datum , ellipsoid or other name B) paste without metric So paste do 2 things paste a coordinate system and PAste a coordinate system Metric ! Where are edit and save thoses 2 informations inside manifold ? in which context we need to paste with or without metric ? Thank's Attachments: coordinateSystemMEtric.png pasteWithmetric.png paste_doc.png projection_difference.png
