Location Display and Entry Formats


Location display & entry formats




You can choose the format under which RASTRAC outputs latitude and longitude by changing the setting in the "Tools... Options... System... System" property sheet. The chosen output format will be used for new textual lat/lon data in all displays, recorder files, and legend files. While you must choose one output format, you may use any combination of the four input formats when you are prompted to type in a latitude or longitude. The different formats are listed below.

HDD MM SS.SSS

HDD MM.MMM

HDD.DDDDDD

+/-DD.DDDDDD


Each is described here in detail:

1. HDD MM SS.SSS
   
   

"H" = N (North), S (South), E (East), or W (West).
"DD" = degrees component of lat/lon value. You should use 2 digits for latitude and 3 digits for Longitude.
"MM" = arc-minutes (60ths of a degree) component of lat/lon value. You should always use 2 digits.
"SS.SSS" = floating-point arc-seconds (60ths of an arc-minute) component of lat/lon value. A decimal point must be included.

2. HDD MM.MMM
   
   

"H" = N (North), S (South), E (East), or W (West).
"DD" = degrees component of lat/lon value. You should use 2 digits for latitude and 3 digits for longitude.
"MM.MMM" = floating-point arc-minutes (60ths of a degree) component of lat/lon value. A decimal point must be included.

3. HDD.DDDDDD
   
   

"H" = N (North), S (South), E (East), or W (West).
"DD.DDDDDD" = floating-point degrees component of lat/lon value. A decimal point must be included.

4. +/-DD.DDDDDD
   
   

"+/-" = "+" or "-" character
"DD.DDDDDD" = floating-point degrees component of lat/lon value. A decimal point must be included.

Note: When you’re using this format while typing in a location, it is very important to include the decimal point in the desired field. RASTRAC uses the location of the decimal point character to determine which format you’re using.
