WMS:Projection Dialogs
This contains information about future functionality available starting at WMS version 11.0. The content may not apply to other versions. |
There are two main projection dialogs used in WMS: The Display Projection dialog, and the Object Projection dialog. From each of these, the Horizontal Projection dialog can be accessed. More detailed information about each projection and the information in these dialogs can be found in the WMS:Projections article.
Display Projection Dialog
The Display Projection dialog contains settings which are applied to the project as a whole.
Horizontal section
The Horizontal section of the dialog has two options available via radio buttons:
- No projection – This option doesn't set a projection, and only allows adjusting the horizontal Units used in the project. The available units include:
- "U. S. Survey Feet". Equal to 1200⁄3937 meters, approximately 0.3048006096 meters.
- "International Feet". Equal to 0.3048 meters.
- "Meters". Equal to the distance traveled by light in vacuum within 1⁄299792458 of a second.
- "Inches". Equal to 1⁄39.37 of a meter.
- "Centimeters". Equal to 1⁄100 of a meter.
- Global projection – Clicking on the Set Projection button allows more specific projections to be set. These are listed below in the Horizontal Projection Dialog section.
Vertical section
The Vertical section has two drop-down boxes:
- Projection, giving the following options:
- "Local"
- Units, giving the following options:
- "U. S. Survey Feet"
- "International Feet"
- "Meters"
- "Inches"
- "Centimeters"
Object Projection Dialog
The Object Projection dialog is the same as the Display Projection dialog, but only applies to one specific object (e.g., a coverage or a mesh). It can be accessed by selecting the object in the Project Explorer, then right-clicking on it and selecting Projection... from the menu.
Horizontal Projection Dialog
The Horizonal Projection dialog allows setting a global projection. The dialog contains three main sections: the projection list, the projection filter and import options, and the current selected projection display.
The project list shows all currently available projections. The list has four main sections:
- Favorite Projections – Contains a list of most used and favorite projections. To add a projections to this list, right-click click on the projection and select Add to Favorites. Right-clicking on a projection in the favorites list has the options to remove it from the list or the rename the projection.
- Recent Projections
- Geographic Coordinate Systems
- Projected Coordinate Systems
The filter and import options sections contains the following options:
- Filter strings
- Add Projections From:
- EPSG Code
- *.prj file
- Library
