Warnings

On the Warnings page, you can select whether you want common warning messages to be displayed. By default, all messages are selected.

To turn off one or more messages from being displayed when the relevant event occurs, clear the applicable check box.

Each message is described as follows:

Attempting to view data with METER projection: This message appears every time you open a layer that has a default Meter projection assigned. Some file formats do not save projection information but do have bounding coordinates. Such layers are assigned a METER projection by default. This message reminds you to assign the appropriate projection to the data.
Attempting to view data that must be reprojected: This message appears when you try to add data to a project that is not the same projection as the active map. When you do so, Focus reprojects the new data to the projection of the active map.
Creating a new area to view data that cannot be reprojected: This message appears when you try to add data that cannot be reprojected to an active map that has a projection assigned already. Data that cannot be reprojected includes layers or files that have METER or PIXEL georeferencing assigned. In such a case, a new area is created for the layer.
Attempting to create an RGB map layer using non-existent channels: This message appears when you try to add an RGB map layer using a non-existent or invalid channel number; that is, other than that specified on the Default RGB page. This message will mention a non-possible request for RGB mapping and reminds you that channels 1, 2 ,3 will be displayed for the RGB map layer.
Modifying a layer's representation may affect other layers: This message appears when you edit a representation that is linked to more than one layer. By editing the representation style of one layer that is linked to an RST, the representation style of another layer that is also linked to the same RST may change if the same REPCODE is used by both layers. This message notifies you that the representation changes being made to one layer may also affect another layer.
Required input is missing in the Atmospheric Correction wizard: This message appears when information about an atmospheric-correction operation is missing and the system cannot carry out the requested operation.
Required input is missing in the Layer Manager: This message appears when information is missing in the Layer Manager window and the system cannot complete the requested action.
Fully Within spatial operator not available for thematic rasters: This message reminds you that you are attempting to use Fully Within on a thematic raster.
Attempting to view data from an unconnected table: This message appears when you try to view data from a layer that contains attributes not associated directly with a vector representing a geographical location.
