Mosaic with images of two UTM zones

OTB Usage
1

Dear all,

I don’t manage to do a mosaic with my 3 Sentinelle images with OTB. I have tried with OTB 6.6 and OTB 7.0 (Windows10). I tried with the line command and with Monteverdi.

I have 3 Sentinelle images, 2 of them have this file information:
Dims: 10980 x 10980 x 3 [BIP]
Size: [Floating Point] 1,446,906,929 bytes.
File Type : TIFF
Sensor Type: Unknown
Byte Order : Host (Intel)
Projection : UTM, Zone 56 South
Pixel : 10 Meters
Datum : WGS-84

1 has this file information:
Dims: 10980 x 10980 x 3 [BIP]
Size: [Floating Point] 1,446,906,929 bytes.
File Type : TIFF
Sensor Type: Unknown
Byte Order : Host (Intel)
Projection : UTM, Zone 55 South
Pixel : 10 Meters
Datum : WGS-84

I tried to use:

  • Mosaic
  • Superimpose before mosaic

How do you manage to mosaic them with OTB ?
I manage with two others softwares (ENVI and ArcGis) but I need to do it with OTB.

Hi Natacha,

SuperImpose will try to crop your input image onto a target image, using the target image projection and resolution.

I think you can use GDAL to convert your image in the common projection :

gdalwarp -t_srs EPSG:CODE input_file ouput_file

To find the EPSG code, you may browse https://www.epsg.io

Hope that helps,
