GDALers:
I have recently come across the mosaicking magic that is 1) build a vrt usin
gdalbuildvrt and then 2) gdal_translate the vrt to whatever format I want --
I'm noticing this is a crazy-fast way to do mosaicking compared to some
other techniques. My current issue is that I have a set of MODIS HDF4
files, and I'd like (if possible) to repeat this process, using a specific
layer in the HDF to be mosaicked. What is the trick to doing this? As far
as I know, all the tiles have the same subdataset name. I suppose I can
gdal_translate each tile first, then build the vrt, then re-export the vrt,
but I wanted to know if there was a faster way to do this (e.g. skipping the
initial gdal_translate)?
Here's the gdalinfo dump of one of the tiles. I'm interested in mosaicking
the HDF4_EOS:EOS_GRID:"MCD15A2.A2002185.h14v10.005.2007172042412.hdf":MOD_Grid_MOD15A2:Lai_1km

MOD15A2_FILLVALUE_DOC=MOD15A2 FILL VALUE LEGEND
255 = _Fillvalue, assigned when:
* the MODAGAGG suf. reflectance for channel VIS, NIR was assigned its
_Fillvalue, or
* land cover pixel itself was assigned _Fillvalus 255 or 254.
254 = land cover assigned as perennial salt or inland fresh water.
253 = land cover assigned as barren, sparse vegetation (rock, tundra,
desert.)
252 = land cover assigned as perennial snow, ice.
251 = land cover assigned as "permanent" wetlands/inundated marshlands.
250 = land cover assigned as urban/built-up.
249 = land cover assigned as "unclassified" or not able to determine.

MODLAND_QC START 0 END 0 VALIDS 2
MODLAND_QC 0 = Good Quality (main algorithm with or without saturation)
MODLAND_QC 1 = Other Quality (back-up algorithm or fill value)
SENSOR START 1 END 1 VALIDS 2
SENSOR 0 = Terra
SENSOR 1 = Aqua
DEADDETECTOR START 2 END 2 VALIDS 2
DEADDETECTOR 0 = Detectors apparently fine for up to 50% of channels 1,2
DEADDETECTOR 1 = Dead detectors caused >50% adjacent detector retrieval
CLOUDSTATE START 3 END 4 VALIDS 4 (this inherited from Aggregate_QC bits
{0,1} cloud state)
CLOUDSTATE 00 = 0 Significant clouds NOT present (clear)
CLOUDSTATE 01 = 1 Significant clouds WERE present
CLOUDSTATE 10 = 2 Mixed cloud present on pixel
CLOUDSTATE 11 = 3 Cloud state not defined,assumed clear
SCF_QC START 5 END 7 VALIDS 5
SCF_QC 000=0 Main (RT) algorithm used, best result possible (no
saturation)
SCF_QC 001=1 Main (RT) algorithm used, saturation occured. Good, very
usable.
SCF_QC 010=2 Main algorithm failed due to bad geometry, empirical
algorithm used
SCF_QC 011=3 Main algorithm faild due to problems other than geometry,
empirical algorithm used
SCF_QC 100=4 Pixel not produced at all, value coudn't be retrieved
(possible reasons: bad L1B data, unusable MODAGAGG data)
