The latitude and longitude of points in Venârivè can be determined using the Venârivè map, and/or from the Ports and Markets of Venârivè table in Appendix XV.Further instructions and tips on using the form are provided below.
- Latitude: This is used enter northern or southern latitude of the point in question on Kèthîra. Enter an integer number 1 and 90, which gives the degrees of latitude, then after a single blank space enter the number of 'minutes', a non-negative integer between 0 and 60. Then finally enter another blank space and specify N or S (for North or South). Note that it is possible, to use negative numbers, but it really only complicates matters.
- Longitude: This is used to specify the longitude (meridian) of the point in question on Kèthîra. Enter an integer number between 1 and 180, which gives the degrees, then after a single blank space enter the number of 'minutes', which should be a non-negative integer between 0 and 60. Then enter another blank and specify E or W (for East or West). Note that you can, if you wish, use negative degrees longitude, so that
"-180 0 E"is equivalent to
"180 0 W", but it really only complicates matters.
- Time: This is used to specify the date and time of the year when the "night sky" is being viewed. This may actually be daytime as well; the effect of the sun is ignored. Enter the month (1 to 12) followed by a dash followed by the day of the month followed by a blank (e.g. 6-5 ). Then enter the hour of the day (in 0-24 notation) followed by colon and the number of minutes. For example
"6-5 15:15"would be the 5th day of the 6th month at 3:15pm.
