Re: [las_users] Re: FW: LAS 8.6.9 How to set region(0) for dataset


Or, if the dataset has longitudes -180:180 and you want it to show as 0:360 then find the x-axis descriptions in the xml and change the ranges.  If it looks like this

  <XAXIS-x-id-e6b96cc92f type="x" units="degrees_east">
    <arange start="-179" size="360" step="1" />

you'd change that to,

  <XAXIS-x-id-e6b96cc92f type="x" units="degrees_east">
    <arange start="1" size="360" step="1" />

and the software will handle getting the data from the -180:180 grid and showing it in 0:360.  Sometimes the xml file can list more than one definition of the same axis in the <axes> section. Make sure you find them all.

I need more information to understand what you want to do.

If the data set displays as a global as -180 to 180 and it's not a global data set, then just change the definition of the x-axis in the config to have the longitude range such that it covers the area you want it to cover. If it is a global data set and the problem is you want a different line of longitude in the center of the plot, just configure the axis so that the longitude line you want is in the center. Like say start=0, step=1 size=359. If it's a global data set, but you want it to open up zoomed in on a different region you can probably configure the sub-region as properties in the data set, but I haven't tried that to be honest.

Let me know what you need done and we'll try to figure it out.

Subject: LAS 8.6.9 How to set region(0) for dataset


I would like to preset the region to region(0) for a particular dataset using LAS 8.6.9.  It originally displays as Global (180) which is inconsistent with the other datasets we have. 


Has anyone done this and if so, how did you accomplish this?
