WMS:Map Properties

The Map Properties dialog is used when ArcObjects© is enabled to specify the coordinate system to display (or map features) from the ArcGIS© data layer. An ArcGIS data layer should have a currently defined coordinate system associated with it. If the coordinate system is geographic (latitude/longitude), then ArcObjects© is able to "guess" correctly at the projection. Using the coordinate system as defined in the Map Properties a user can specify the coordinate system to use to display features or rasters in WMS. While this does not change the actual geometry of the layer, it will display in the WMS window according to this projection and any data mapped to WMS coverages will be mapped into the coordinate system specified by the Map Properties dialog.

Map Properties Dialog

The dialog is accessed through the Data | Map Properties command when ArcObjects© is active. The dialog has the following options:

• Spacial Filter – This drop-down menu has two commands:

• Set Spacial Filter – Brings up the Spacial Filter Extent dialog.
• Clear Spatial Filter – Removes anything entered int the search field and reset the coordinate system browser field.

• Search – A user can type a desired coordinate system into the search field. After pressing the Search button, any matching coordinate systems found will appear in the coordinate system browser field below.
• Clear Search – Clears the search field and resets the coordinate system browser field below.
• Add Coordinate System – This drop-down menu contains the following sub-menu and commands:

• New – This sub-menu is for commands that create new coordinate systems. It has the following options:

• Geographic Coordinate System
• Projected Coordinate System

• Import – Launches a browser where a coordinate system file may be imported.
• Clear – Removes any coordinate systems that have been added by the user.

• Add to Favorites – Places the selected coordinate system in "Favorites" folder for easier access in the future.
• Coordinate systems browser – By opening the tree items in this field, coordinate systems can be selected to be applied to GIS data. The browser contains a right-click menu with the following commands:
• Current coordinate system – Displays the current selected coordinate system.
• Transformations – Brings up the Geographic Coordinate System Transformations dialog.
