RE: V elements in time axis

Ben,

The time parsing rules are laid out in TMAPDate.pm, and in a nutshell, the date/time must be formatted as either:
YYYYmmDDHHMMSS
or:
DATE[ [h[:min[:s]]]

In the second case, there can be one and only one space between the date and time, the time separator must be a colon, 'h' must be an integer <= 24, 'min' must be an integer <= 60, 's' must be an integer <= 60, and the 'DATE' part must follow one of the following formats, with the caveat that the date separator can be either a dash (-), slash (/), or period (.):

YYYY-MMM-DD
MMM-DD-YYYY
DD-MMM-YYYY
YYYY-MMM-D
MMM-D-YYYY
D-MMM-YYYY
YYYY-mm-DD
YYYY-mm-D
YYYY-m-DD
YYY-mm-DD
YYYY-m-D
YYYYmmDD
YYY-m-DD
YY-mm-DD
YYY-m-D
YY-m-DD
YY-mm-D
Y-mm-DD
YY-m-D
Y-mm-D
Y-m-DD
DD-MMM
MMM-DD
Y-m-D
D-MMM
MMM-D
MMM

An example that works for me is:

 <avhrr_hourly_time units="hours" type="t">
  <v>2003-06-25 22:14:00</v>
  <v>2003-06-26 20:23:00</v>
  <v>2003-06-26 22:03:00</v>
  <v>2003-06-27 21:51:00</v>
  <v>2003-06-28 21:40:00</v>
  <v>2003-06-29 21:29:00</v>
  <v>2003-06-30 21:18:00</v>
  <v>2003-07-01 21:06:00</v>
 </avhrr_hourly_time>

Subject: V elements in time axis


Hello All,

I have satellite data that does not occur at regular time intervals, so I wa
nt to put the actual times of the satellite passes in the axis time definiti
on as V elements (unless someone can tell me a better method).  I successful
ly implemented V elements on the Z axis as:

<axes>
 <NSA_BTS_Z units="Meters" type="z">
  <v>2</v>
  <v>10</v> 
  <v>20</v>
  <v>40</v>
 </NSA_BTS_Z>
</axes>

But I haven't had any success doing it on the time axis.  I've tried the fol
lowing types of combinations:

 <satellite_T units="hours" type="t">
  <v>2001-10-31  12</v>
 </satellite_T>
</axes>


 <satellite_T units="hours" type="t">
  <v>"2001-10-31  12"</v>
 </satellite_T>
</axes>


 <satellite_T units="hours" type="t">
  <v>F13SSMI1B_200107152131_wpo_low</v>
 </satellite_T>
</axes>


 <satellite_T units="hours" type="t">
  <v>1</v>
 </satellite_T>
</axes>


The make always gives me an error message pointing to the first element of t
he "t" definition.  I can't get any combination to work.  I suspect that tim
e is a special case that need extra information, but I don't know what it is
  If anyone has any successful example of using elements in t please show m
e your successful case.

Ideally I will put strings like F13SSMI1B_200107152131_wpo_low in the elemen
ts and the strings will be passed from the UI server to the Data server.  Th
is string is the file name and I can use this directly to access the data fi
le.  But information on any working combination would be greatly helpful.

Thank you,

Ben
