| Oct 27, 2011 at 11:42 | comment | added | Andy Harfoot | My experience is that even though ECWs can have georeferencing information (GeoECWs), they don't record the coordinate system. This situation is sufficient for an image to be displayed in ArcGIS and QGIS (not sure about the others in the list), but isn't sufficient for MapInfo, which requires a coordinate system to be specified for every layer. Therefore (again in my experience, happy to be proved wrong) you will always have to provide at least the coordinate system to MapInfo when opening a GeoECW for the first time (probably using the MapImagery plugin) | |
| Oct 27, 2011 at 4:27 | comment | added | Summit GIS and Mapping | As I've commented below, this is the first time that I've used MapInfo for about 7 years, and I'm most surprised that I can't just add an ECW image to the workspace like I can with ArcMap, Manifold, uDig, QGIS & gvSIG! The ECW already has all the necessary coordinate information embedded in the image header (this can be confirmed using the ECW Header Editor application available for download from the ERDAS web page). | |
