Configuring the 'Constraints' page behavior

[Akshay-Hegde]

I see, website is getting updated, so could be the reason some docs I am missing, I was searching for docs for Configuring the 'Constraints' page behavior, it would be helpful for me, time being if you can share docs either pdf or anything, and one more query which I have is I am trying to configure dropdown menu which will have lat and longs like below, so when user selects dropdown say with value 15,90, I would like to set region 90,90,15,15 , my ui.xml file looks like below, where I am trying to keep only view t, zt to user, along with that I would like to disable default analysis, I have included rama_ui.xml#rama in my dataset, also added in ui.xml but not able to see dropdown menu, can we have dependent dropdown for region also ? please guide me Here is link to my config files

<menu type="constraint" name="rama_buoy_positions"> 
 <item values="15,90">15N, 90E</item> 
 <item values="12,90">12N, 90E</item> 
 <item values="0,90">0, 90E</item> 
 </menu>

<map type="ops" name=rama_ops">
 <ifmenu view="zt" href="#Ops_Std2D_t"/>
 <ifmenu view="t" href="#Ops_Std1D_t"/> 
 <constraint type="variable"/> 
 <constraint type="text" name="location_dropdown"> 
       <menu href="#rama_buoy_positions"/> 
 </constraint>
 </map>

<defaults>
<default name="rama">
   <map href="#rama_ops"/>
 </default>
</defaults>

Not sure exactly where you expect the menu to appear and under what circumstances. And you're probably running to some issues with out of date documentation. That said, you can create named regions that will show up in the menu for the navigation map. They appear when you select the button on the right with the downward pointing chevrons. That might be easier.

@noaaroland I understood how to setup named region, but is it possible to project at fixed latitude and longitude by default, when user clicks dataset, as you can see below, By default I would like to show 15N, 90E to user instead, and want to allow user to select only the regions which are listed, rather than allowing user to select anything within bounding box

<menu type="constraint" name="rama_buoy_positions"> 
 <item values="15,90">15N, 90E</item> 
 <item values="12,90">12N, 90E</item> 
 <item values="0,90">0, 90E</item> 
 </menu>

By default LAS creates rectangle with available min and max of lat & lon, in current scenario its, 25S - 25N, and 55E-100E, means anything within this bounding box user can select data,

Also I would like allow user to plot either line plot (t) or Z-time (zt), how to I do that, Here is link to all my config

If these data are timeseries at fixed points, or some other time of discrete geometry you should serve them with ERDDAP use the discrete geometry capabilities.

[Akshay-Hegde]

@noaaroland Yes these data are timeseries (RAMA buoy) at fixed points, but not from ERDDAP, unfortunately these files aggregated in thredds. is it possible to add them without having ERDDAP ?

Here is sample file : https://drive.google.com/open?id=0B6_-5klDxENTSnlyZ1JJS3BMdVk

[noaaroland]

Yes, you can add them as degenerate grids, but as you've discovered the UI lacks some obvious features.With data from ERDDAP all of the constraint UI features can be build automatically by software when adding the data set. Features like being able to select individual buoys by name, etc. using ERDDAP is the method we recommend and the only method we currently support for discrete data.

[Akshay-Hegde]

@noaaroland , thank you, but one obvious issue which exists is running both ERDDAP and LAS together with same java version, unfortunately Java 1.7 is no longer supported in ERDDAP, requires 1.8 minimum.

[noaaroland]

LAS runs fine with Java 8. 7 is the minimum. We routinely run both with 8.
