Use the Info pane to manually assign an initial coordinate system when importing from a format that does not specify the coordinate system. |

An essential example on changing the projection of a drawing, either within the drawing itself, or by changing the projection of a map window that shows the drawing and on the fly reprojects the drawing for display. |
|
Use the Reproject Component command to change the projection of an image, raster data showing terrain elevations in a region of Florida, from Latitude / Longitude to Orthographic centered on Florida. |

Step by step example showing how to add a frequently used coordinate system to the Favorites system. |
|
A lengthy example exploring projection dialogs and a classic projection problem. We save a drawing into projected shapefiles and then show on import how a projection can be quickly and easily checked and corrected if it is wrong. |

Illustrates use of rotated views, that is, map displays which are not "North up," using a Bing street map image server layer, to show how even layers fetched on the fly from a web server can be rotated. The topic also shows an alternate way of creating North arrows that is initially simpler, but ultimately much less convenient than the more sophisticated method illustrated in the Rotated Views topic. |

In this example we use a few snippets of easy SQL to list NTv2 and NADCON transformation grids that are available within the grids.dat compressed collection of transformation grid files. Grid transformation files can be used when creating custom base coordinate systems, for NADCON / HARN / HPGN and NTv2 high accuracy transformations that use grid files. |
