How do I reproject my data?

Discover provides a number of different Reprojection Utilities, depending on the type of data to be transformed. Each of these tools will create a copy of the data in the specified output projection, typically with a default _reproject suffix added to the input file name. These tools are invaluable (for example) for ensuring all datasets are in the same Coordinate Reference System (projection).

Note, after reprojecting when you open in back in the map window, it will appear in exact same location. This is due to Mapinfo beign a GIS system that reprojects on the fly. It will only appear in a different location when opened in a non-GIS program.


Vector data (i.e. points/polylines/polygons)

This is shown in the layer control with an icon -


Use the DISCOVER > Reproject > Multi-Table Reproject tool. This allows the current projections of multiple vector tables to be displayed and reprojected, either as new tables, or overwriting the existing tables.


Raster Images (e.g. aerial or satellite photography, scanned images from open file reports)

This is shown in the layer control with an icon -


Use the IMAGES> Reproject Image tool 



Gridded Surfaces (e.g. DEM/topographic grids, geochemical and geophysical surfaces)

This is shown in the layer control with an icon -


Or if opened as a Raster Image -


Use the Surfaces > Grid Utilities >Reproject tool (via Discover > Surfaces menu)
