# Find maplets containing surface point

(lithos Main Menu Option F. Find maplets containing surface point)

## Description

This Main Menu option allows you to find a specific maplet that falls within a range of values that you input. This is useful for finding a maplet/bigmap based upon a picture, lat/long, or maplet/bigmap.

### Prompts

When you enter Option F. Find maplets containing surface point from the Main Menu, you will see these prompts:

pixlinpic (p) or ltdlng (l) or map p/l (m)? - Selects one of these choices:

• Entering 'p' prompts for a picture name, then a pixel/line location on that image. For example, on an image with a resolution of 1024X1024, '0 0' refers to the upper left of the picture and '512 512' refers to the center of the picture.

• Entering 'l' (lowercase ell) prompts for the latitude and west longitude. This option uses the shape model for determining lat/lon.

• Entering 'm' prompts for a landmark name, then a pixel/line location on that landmark. JRW edit 08 Nov 2021: '0 0' is the upper left, 'q q' is the center, and '2*q 2*q' is lower right. This is because Bob stores the matrix as -q to q, which includes 0.

The output of all 3 options is the same. It contains these elements:

Lat/Lon/Rad - Displays the Latitude/Longitude/Radius (in km) of the location you specified. These values come from the shape model.

Column 1 - The name of the maplet/bigmap.

Column 2 - GSD in km of the maplet/bigmap.

Column 3 - Pixel location of the specified lat/lon on the maplet.

Column 4 - Line location of the specified lat/lon on the maplet.
