Does anyone know why the south African national grid projections display upside down in ArcMap? ESRI appear to have deviated from the standard EPSG definitions by inverting the scale factor. If I customise the scale factor then it displays the correct way up again. In desktop this is fine but on the web it is causing me issues
For example I have some data that is correct if using EPSG definition 2054. The ESRI definition with the same coordinate system but inverted scale factor is 102488. Unfortunately my coordinate data is in a third party system and I'd prefer not to edit it. The WKID is stored in that system as 2054. Unfortunately the out of the box geometry server does not include 2054 as a definition so on projecting in a webmap it fails to recognise the WKID and puts the data at the same coordinate location in web Mercator (middle of the atlantic ocean)
