Count of Found Features

The count of features found in the search appears just above the search results. This count includes the number of unique features listed in the results. If the same feature is listed twice, (such as for Mars Planetocentric East and Mars Planetographic West), it will only count as one feature in the resulting count of features found.

Show or Hide Fields

To show or hide some of the fields (columns) returned in the results, choose which columns to show:

Search Results: Choose the field to show by clicking the square checkbox beside the desired field name at the bottom of the page in the Select fields to display section and hit the "Submit Your Choice" button. The Show All Fields link in the upper left will reload the page with all the fields showing.
Advanced Search Page: Choose the Show or Hide buttons below each field name. The Show All Fields link in the upper left will turn all the Show buttons on, allowing you to continue to make changes to the search parameters before retrieving the results.

The feature name, or Name field, can never be hidden. Click the feature name to see all the details about that feature.

Show All Fields will show a new field Name (Legacy). This field shows the "old style" spelling of the feature name using specialized codes in place of letters with diacritical marks. The old style diacritical codes are three characters, starting with a pipe (|), followed by a symbol representing the diacritical mark (for example, colon ':' for an umlaut), and the letter to which the diacritical mark is applied. For example, |:u represents ü (lower case u with an d umlaut).

Sorting

To sort the results, choose which columns to use for sorting:

Search Results: Click an arrow in the header of the column you wish to sort. The arrow pointing up will sort the results in ascending order (A-Z), and the arrow pointing down will sort the results in descending order (Z-A).
Advanced Search Page: Choose the column you wish to sort on in the Sort Results By menu at the bottom of the page above the Search button. The results will be sorted in ascending order (A-Z) based on the contents of that column.

Map and Quad sorts are complex, and may take a minute or two to return the results.

All letters with diacritical marks and names in brackets are sorted alphabetically, ignoring the diacritical marks and brackets. For example, [Yakovlev] appears before Yeats, and Sūr Dās appears before Surikov.

Body

The body option selects which bodies to include in the search. The option "All Bodies" will be checked when the page is loaded. To narrow the search to one or more bodies click on the body or bodies of interest. Note at least one option must be selected for the search to work properly.

Feature Name

This option will restrict the search to features that contain the input letters in the name. The search is case insensitive, so the feature name can be input as upper or lower case. Note if this field is left blank all feature names will be searched.

Example:

If "Mon" is input, the feature names selected would include:
Acmon
Akna Montes
Anala Mons

The asterick character (*) may be used as a wildcard.

Example: If "Vall*s" is input, the feature names selected would include:
Vallis Alpes
Valles Marineris

When searching for names containing letters with diacritical marks, unmarked letters may be used.

Examples: Cezanne will return Cézanne
Kenko will return Kenkō

Feature Type

The feature type option selects which feature types to include in the search. The option "All" will be checked when the page is loaded.

Diameter

This option will restrict the search to features that are a specific diameter or in a selected range of diameters. The "Greater Than" field is the lower bound of diameters that will be selected and the "Less Than" field is the upper bound. Note if this field is left blank all features will be searched.

Examples:
If "100" is input in the "Greater Than" field and the "Less Than" field is left blank, only features greater than 100 will be returned in the search.
If "100" is input in the "Greater Than" field and the "Less Than" field is "230" only features greater than 100 and less than 230 will be returned in the search.

Latitude/Longitude Window

This option will restrict the search to features that are within a selected area on the face of a body. The four fields are used to create a window within which the search will be performed. Note if these fields are left blank all features will be searched. Longitudes may be provided in either Western Longitude or Eastern Longitude coordinates by selecting one of the buttons to denote the choice, and the correct area of each body will be searched.

Examples:

For a Western Longitude search:
If "Northern Latitude of Window" is "30"
"Southern Latitude of Window" is "10"
"Western Longitude of Window" is "50"
"Eastern Longitude of Window" is "30"
The search will concentrate on:

a 20° by 20° box centered at 20° northern latitude and 40° western longitude on western longitude bodies, and
a 20° by 20° box centered at 20° northern latitude and 320° eastern longitude on eastern longitude bodies.

For an Eastern Longitude search:
If "Northern Latitude of Window" is "30"
"Southern Latitude of Window" is "10"
"Western Longitude of Window" is "30"
"Eastern Longitude of Window" is "50"
The search will concentrate on:

a 20° by 20° box centered at 20° northern latitude and 40° eastern longitude on eastern longitude bodies, and
a 20° by 20° box centered at 20° northern latitude and 320° western longitude on western longitude bodies.

Note the following when using this option:

The longitude option, Western Longitude or Eastern Longitude, does not affect the longitude results returned by the search. The longitude values displayed in the search results will be in the default coordinate reference system for each body, as described here:

Northern latitudes are positive numbers, southern latitudes are negative numbers.
The Moon longitude ranges are 0° to 180° for the eastern hemisphere, and 0° to -180° for western hemisphere.
Longitude increases to the east from 0° to 360° for Venus, Dactyl, Miranda, Ariel, Umbriel, Titania, Oberon, Triton, and Mars Planetocentric East.
Longitude increases to the west from 0° to 360° for all other bodies.

Approval Date Range

This option will restrict the search to features that have an approval date within a selected range. The "Beginning Date" field is the lower bound of date that will be selected and the "Ending Date" field is the upper bound. Note if this field is left blank all features will be searched.

Examples:
If "1974" is input in the "Beginning Date" field and the "Ending Year" field is left blank only features that have been approved since 1974 will be returned in the search.
If "1900" is input in the "Beginning Date" field and the "Ending Year" field is "1950" only features approved between 1900 and 1950 will be returned in the search.

Starting in September 2006, the full date of approval is recorded (year, month, and day). To narrow a search to a month, provide the year and month as the starting and ending dates. To narrow a search to a few days or weeks, fill in the year, month, and day for the starting and ending dates.

Examples:
Beginning Date of "2006-9" and Ending Date of "2006-9" will return all the features approved in the month of September 2006.
Beginning Date of "2006-10" and Ending Date of "2006-11" will return all the features approved in the months of October and November 2006.
Beginning Date of "2006-11-15" and Ending Date of "2006-11-30" will return all the features approved between November 15th and 30th, 2006.

Approval Status

The approval status option selects which approval status to include in the search. The option "ANY" will be checked when the page is loaded.

Continent

This option restricts the search to names from a specified continent or large geographic area that is the origin of the name. Valid entries can be found in the Abbreviations for Continents, Countries, and Ethnic Groups.

Ethnic/Cultural Group or Country

This option restricts the search to names whose origin information have been obtained from a specified source. Valid entries can be found in the Abbreviations for Continents, Countries, and Ethnic Groups.

Reference

This option restricts the search to names whose origin information have been obtained from a specified source. Valid entries can be found in the Sources of Planetary Names.

Quad

This option restricts the search to features associated with the quadrangle name matching the search. Searching for "H-1" will return results for quads H-1 and H-10 through H-15.

Map

This option restricts the search to features associated with the map containing the search value in the publication number or title. Thus, names associated with I2366 can be found by entering "I2366" or "Hellas" for the map search value. The map publication number will be displayed in the results. Click the map publication number to see details about that map if any exist.
