Ticket #6293 – Description
initial v4 1 1 Attempting to use gdalwarp to georegister several MSI tiles from Airbus' Pleiades sensor. A single area is provided in several tiles. In this example, here is the MSI directory listing with two tiles: 2 2 3 {{{DIM_PHR1A_MS_201509141606268_SEN_1627093101-002.XML 3 {{{ 4 DIM_PHR1A_MS_201509141606268_SEN_1627093101-002.XML 4 5 ICON_PHR1A_MS_201509141606268_SEN_1627093101-002.JPG 5 6 IMG_PHR1A_MS_201509141606268_SEN_1627093101-002_R1C1.TFW … … 13 14 PREVIEW_PHR1A_MS_201509141606268_SEN_1627093101-002.JPG 14 15 PREVIEW_PHR1A_MS_201509141606268_SEN_1627093101-002.KMZ 15 RPC_PHR1A_MS_201509141606268_SEN_1627093101-002.XML}}} 16 RPC_PHR1A_MS_201509141606268_SEN_1627093101-002.XML 17 }}} 16 18 17 19 The TFW files are unique between the two tiles. When I import the tiles into qgis, without any modification, it stitches them together properly, but they are not in the proper CRS (they are essentially referenced to pixel space, not to any CRS coordinate system). … … 19 21 When I use gdalwarp to put them in EPSG:4326, the first image is perfectly registered (the image with R1C1 as a suffix).
