Using the Map Panel

The iMap tool has a Map panel (Figure 16-2) that lets you manipulate the map display. The panel also appears when you apply a map projection or shapefile into another iTool.

Table 16-3 describes the items on the Map panel.

Table 16-3: Items on the Map Panel
Name	Description
Location	Displays the following information: If no map projection is applied — the cursor location in degrees longitude/latitude or meters, depending on the image units If a map projection is applied — the cursor location in degrees longitude/latitude and the corresponding Cartesian X/Y (or U/V) coordinates in meters Sensitive only if an image or a contour is selected.
Data Value	Displays the following information: For an image — the data value and corresponding grayscale or RGB value for the current cursor location (identical to Pixel Value on the Image panel) For a contour — the data value for the current cursor location Sensitive only if an image or contour visualization is selected.
Longitude limits	Displays the active map projection's maximum and minimum longitude values. Enter new values to update these limits. Sensitive only if a dataspace (or a visualization within the dataspace) with a map projection is selected.
Latitude limits	Displays the active map projection's maximum and minimum latitude values. Enter new values to update these limits. Sensitive only if a dataspace (or a visualization within the dataspace) with a map projection is selected.
Edit Projection...	Opens the Map Projection dialog for the currently active dataspace. When a projection is applied to an image that has not been registered in degrees or meters, the Map Register Image operation is started. (See Registering an Image.)
