Anton,
you can get the extents of the modis swath file from the metadata.
you have to use the the geolocation arrays to create a grid from the
swath file. the further left and right from the center of the image the
more area the single pixel in the swath file covers. also modis is a
pushbroom sen
Dear Brian,
thank you very much for your reply!
The '-geoloc' switch does produce the error about points failing to
transform but the principal limitation is that I cannot use the '-te'
switch because I cannot know the extent in advance.
My task is to overlay one image (either projected like

EOS_SWATH has 2 geolocation arrays, you might try the -geoloc switch to
gdalwarp, otherwise it creates a handfull of gcps from the arrays, if
you get a error about points failing to transform, set the output extent
with the -te switch.
also you could try the swath2grid application in

Hello everyone!
Some time ago I've asked about problems with gdalwarp (the e-mails
below). I tried to utilize Python binding instead but got the same
results. This brief script overlays the Europe map (GeoTIFF with
geotransform) onto a MERIS images (PDS file with GCPs). But the result
looks
Hi!
I'm not sure but probably my question is related to the one below.
I'm trying to mosaic one MODIS images onto another with GDAL:
gdal_translate
HDF4_EOS:EOS_SWATH:"/Data/sat/GDAL_test/MYD021KM.A2011228.0925.005.2011229003113.hdf":MODIS_SWATH_Type_L1B:EV_1KM_RefSB
-b 1 /data/modis1.tif

Hi,
Hróbjartur Þorsteinsson explained to me a near-hidden feature of GDAL,
namely to reproject one image onto the coverage of another.
Given two images:
imageA.tiff
imageB.tiff
Then an empty image can be created from image A with e.g.
$ gdal_translate -ot Float32 -scale 0 0 999 999 -a_nodata
