Rotation Warning
Introduction
Some raster file may have associated rotation information. This indicates that an appropriated rotation should be applied for the raster to be correctly displayed. ToolMap display a Warning when such files are encountered because displaying those files with rotations isn’t supported yet.
To still use those images we need to convert them into non rotated raster. Following method may be used for that purpose:
Using ArcGIS
- Load the raster
- Right-click the raster name in the Table of contents
- Choose Data → Export Data
- Select the Location, file Format and file name
- Press Save
The new raster is now correct and didn’t contain anymore rotation information
Note about word files (tfw)
Since ArcGIS 9.2 no more word files (tfw) are written and the georeferencing information is now stored in a aux.xml file (http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?id=2670&pid=2664&topicname=About_auxiliary_files). It is however possible to manually create such word file using 'Export Raster Word File' tool from the ArcToolBox
