Using the Feature Finder 


The Feature Finder makes it possible to quickly and easily locate any of the thousands of features in the database, as well as gain access to several important custom features.


NOTE:  When you use the Feature Finder, the following Tool Bar Buttons are temporarily hidden, because they become inactive.  As soon as the Feature Finder is closed, the buttons re-appear on the Tool Bar.  They will also re-appear if you uncheck Select Features with Mouse on the Feature Finder Dialog.



When you open the dialog box, click the down arrow under Select a Feature Type (as shown below), to display the feature types in the drop-down list.  An alphabetical listing of all named features of that type will appear in the right-hand window of the dialog box.  At the same time, all of the listed named features will be highlighted in green on the map display.  In the example shown, Craters has been selected.




Features visible on the displayed hemisphere are listed in black, while features that are not visible, appear in gray.  If you select a feature on a non-visible hemisphere, a dialog appears asking you if you want to rotate the lunar disk.  Click, Yes, if you want the search to be completed.





If you know the name of the feature you want to find, you can quickly locate it, even if you are not sure of the spelling.  The software’s Smart Search capability, will find the name of any feature, if you enter the first two or three letters of the feature name into the Type Name/Click on List text box.


In the following example, we selected the Rimae feature type, and found all the Gassendi Rimae by just entering, Ga into the display window.  Once you click a feature such as, Gassendi I, its name is highlighted, and the software locates the feature, and highlights it in Magenta on the map.




Although the selected feature is highlighted, it may fall outside of the map field-of view, or be so small that you cannot detect it.  The easiest way to find such features is by clicking the Center at Selection Button.  This causes the map to be redrawn with the highlighted feature centered in the field of view. .


If the feature is still not visible, use the Step-in Tool  to increase the image scale.        


If you want to work with a different feature type, return to the drop-down list of feature types, and select another.  If you switch feature types without clearing first, the current selection is automatically cleared.  The Feature Finder has the ablility to locate domes, as well as nearly six thousand lettered sub-craters that can not be identified with the Labeler Tool




If you wish to find craters or any other feature types, but you do not have a particular feature in mind, you can just scroll through the alphabetical listings, and randomly select names.


When a feature name interests you, just use your mouse to click the feature name on the list.  The name will be highlighted, and the software will locate the feature on the map, which will be highlighted in magenta.  In this example, we clicked on the crater, Arzachel.






To identify a map feature, first make sure that the box Select Feature with Mouse shows a check mark.  Move your mouse to the map, and click on any feature highlighted in green.  The selected feature will be highlighted in magenta, and its name will also appear highlighted in the display window.  In the following example, we selected the crater, Hipparchus.




This capability is similar to using Hover, except that you can identify and highlight selected features, while Hover will only identify them for as long as the mouse remains on the selected feature. To select a different crater, click on another highlighted map feature.  As soon as the next selection is made, the previous selection is automatically cleared.  To clear a selection without selecting another feature, click the Clear Selection Button.



If you change the map view in order to locate features that are not visible to earth-bound observers, you can quickly return the map to the normal view for your observing location by opening the Time Manager, and clicking Current.




Once any feature has been selected, you are able to perform additional functions such as: custom labeling, accessing additional feature information, or linking photos or observing notes to the feature.


To custom label, check the box Label Selected Feature, and click the Customize Label Button.




More information about this capability can be found under: Labeling by Specific Feature.


Sunrise/Sunset Data & Gazetteer


Once you locate a feature you also have access to valuable planning information.  When planning an observing or astrophotography session, what could be more useful than knowing the sunrise and sunset date and time for a feature of interest?  Lunar Map ProTM 4.0 DE provides that information, along with other useful data, for every feature in the database.  If, for instance, you wanted information on the crater, Plato, you would select it from the feature list, and click Feature Information.



A pop-up window is activated, and you are provided with longitude and latitude information, the next sunrise and sunset times for both the eastern and western crater rims, and additional reference data.
