Re: [las_users] LAS error

Thanks Roland, it works great!

This is a couple of months old, but I looked at it today and thought it worth a comment since point data will be an area of increasing focus for the LAS team.
All of these comments have to do with the code that will be released soon as LAS v7.2. Running addXML from that code base produces a correct configuration file for this data set: 

<datasets>
<id-6b9dbc4872 name="http://dods.ndbc.noaa.gov/thredds/dodsC/data/wlevel/ptat2/ptat2l2007.nc"; url="http://dods.ndbc.noaa.gov/thredds/dodsC/data/wlevel/ptat2/ptat2l2007.nc";> 
<variables>
<water_level-id-6b9dbc4872 name="Tide Water Level" units="feet" url="#water_level"> <link match="/lasdata/grids/grid-longitude-latitude-time-id-6b9dbc4872" /> 
</water_level-id-6b9dbc4872>
</variables>
</id-6b9dbc4872>
</datasets>
<grids>
<grid-longitude-latitude-time-id-6b9dbc4872>
<link match="/lasdata/axes/longitude-x-id-6b9dbc4872" />
<link match="/lasdata/axes/latitude-y-id-6b9dbc4872" />
<link match="/lasdata/axes/time-t-id-6b9dbc4872" />
</grid-longitude-latitude-time-id-6b9dbc4872>
</grids>
<axes>
<longitude-x-id-6b9dbc4872 type="x" units="degrees_east">
<v>-97.05</v>
</longitude-x-id-6b9dbc4872>
<latitude-y-id-6b9dbc4872 type="y" units="degrees_north">
<v>27.828</v>
</latitude-y-id-6b9dbc4872>
<time-t-id-6b9dbc4872 type="t" units="hour">
<arange start="2006-12-31 23:06:00" size="8760" step="1" />
</time-t-id-6b9dbc4872>
</axes>
However, there appears to be a bug LAS and this data set configuration fails to correctly initialize the map when the data set is selected. We'll take a look at that and get it fixed, but not for this coming release.
If however, you edit the X and Y axis of the configuration to look like this: 

<longitude-x-id-6b9dbc4872 type="x" units="degrees_east">
<arange start="-97.05" step="1" size="1"/>
</longitude-x-id-6b9dbc4872>
<latitude-y-id-6b9dbc4872 type="y" units="degrees_north">
<arange start="27.828" step="1" size="1"/>
</latitude-y-id-6b9dbc4872>
Then everything works beautifully and you can create time series plots from this station in LAS.

Hi,
I am getting the error below when trying to plot a time series graph using data from a buoy. Is it possible to set the properties region_0_x/y_hi/lo in the LAS configuration file?
