I tested Manifold 8 versus QGIS (2.14.9 Essen) ( I know already outdated but still).
- I have Bing Aerial as a background
- I created a new vector layer, and imported my original drawings, having made no changes to the original .prj files !
- Both the automatic spatial reference made by QGIS or setting manually the spatial reference to EPSG 31370 show my drawings well aligned with Bing Aerial
- If I set the spatial reference of my imported drawings to EPSG:31300 then QGIS is showing my drawings totally off position compared with EPSG:31370. EPSG:31370 seems right for QGIS
So, what goes wrong within Manifold 8 ?
Virtual Earth versus my drawings : is manifold making wrong assumptions, applying wrong projections or making wrong transforms in order to align my drawings with VE ? Is this a bug ?
