MAPINFO.TXT

Description

This text file provides details about each map you have in the SPC system. You can use MAPINFO.TXT to identify problems, similar to the ways you use RESIDUALS.TXT.

MAPINFO.TXT is created by residuals.

  • (!) The symbols that may show up in the Flag column are based on the parameters passed into residuals.

Here is a sample MAPINFO.TXT file. Elements of the data in each of the three sections are explained below.

Section 1

The columns in the first set of output contain this information:

  • Column 1 - landmark name

  • Column 2 - landmark resolution

  • Columns 3-5 - lat, lon, radius

  • Column 6 - number of images contributing to landmark

  • Column 7 - number of maplets the landmark overlaps

  • Column 8 - number of images with landmark on limb

  • Column 9 - magnitude of formal uncertainty in meters

  • Column 10 - Flag, which may be:

    • >> - Flag showing landmarks that are below the pixel threshold

    /!\ You might want to look at these further.

    • ** - Flag indicating fewer than 3 images were included

  • Column 11 - RMS pixel/line vector residual of the nominals and position

Section 2

The two lines in this section present

  • the RMS of all the maplet's position uncertainty
  • the number of landmarks in use

    /!\ The landmark residual is in kilometers unless you include the line UNIT='METER' in INIT_LITHOS.TXT.

Section 3

This matrix plots the number of landmarks in each region of the surface. It uses 10-degree bins with vertical from 90 to -90 (A-I) and horizontal from 0-360 (A-R). The maplet name is defined by this gridded region.
