Hi,
I have a sequence of netCDF files with lat/lon defined as:
float lat(lat) ;
lat:units = "degrees_north" ;
lat:actual_range = 90.f, -90.f ;
lat:long_name = "Latitude" ;
float lon(lon) ;
lon:units = "degrees_east" ;
lon:long_name = "Longitude" ;
lon:actual_range = 0.f, 357.5f ;
...
data:
lat = 90, 87.5, 85, 82.5, 80, 77.5, 75, 72.5, 70, 67.5, 65, 62.5, 60,
57.5,
55, 52.5, 50, 47.5, 45, 42.5, 40, 37.5, 35, 32.5, 30, 27.5, 25,
22.5, 20,
17.5, 15, 12.5, 10, 7.5, 5, 2.5, 0, -2.5, -5, -7.5, -10, -12.5,
-15,
-17.5, -20, -22.5, -25, -27.5, -30, -32.5, -35, -37.5, -40, -42.5,
-45,
-47.5, -50, -52.5, -55, -57.5, -60, -62.5, -65, -67.5, -70, -72.5,
-75,
-77.5, -80, -82.5, -85, -87.5, -90 ;
lon = 0, 2.5, 5, 7.5, 10, 12.5, 15, 17.5, 20, 22.5, 25, 27.5, 30,
32.5, 35,
37.5, 40, 42.5, 45, 47.5, 50, 52.5, 55, 57.5, 60, 62.5, 65, 67.5,

72.5, 75, 77.5, 80, 82.5, 85, 87.5, 90, 92.5, 95, 97.5, 100, 102.5,

107.5, 110, 112.5, 115, 117.5, 120, 122.5, 125, 127.5, 130, 132.5,

137.5, 140, 142.5, 145, 147.5, 150, 152.5, 155, 157.5, 160, 162.5,
165,
167.5, 170, 172.5, 175, 177.5, 180, 182.5, 185, 187.5, 190, 192.5,
195,
197.5, 200, 202.5, 205, 207.5, 210, 212.5, 215, 217.5, 220, 222.5,
225,
227.5, 230, 232.5, 235, 237.5, 240, 242.5, 245, 247.5, 250, 252.5,
255,
257.5, 260, 262.5, 265, 267.5, 270, 272.5, 275, 277.5, 280, 282.5,
285,
287.5, 290, 292.5, 295, 297.5, 300, 302.5, 305, 307.5, 310, 312.5,
315,
317.5, 320, 322.5, 325, 327.5, 330, 332.5, 335, 337.5, 340, 342.5,
345,
347.5, 350, 352.5, 355, 357.5 ;
I create an aggregation with these files and include the following in a
<metadata> element.
<geospatialCoverage>
<northsouth>
<start>-90</start>
<size>73</size>
<resolution>2.5</resolution>
<units>degrees_north</units>
</northsouth>
<eastwest>
<start>0</start>
<size>144</size>
<resolution>2.5</resolution>
<units>degrees_east</units>
</eastwest>
</geospatialCoverage>
When I look at the HTML of the THREDDS catalog using TDS
(Implementation-Version: 3.16.32) I get this:
GeospatialCoverage:
- Longitude: 0.0 to 144.0 Resolution=2.5 degrees_east
- Latitude: -90.0 to -17.0 Resolution=2.5 degrees_north
Have I misinterpreted the documentation, is this a bug in TDS, or what?
Thanks,
Roland
