From my search in INPE's resources, the WPM sensor uses the same grid of MUX sensor. From that, all grids that i can found are here: www.dgi.inpe.br/documentacao/grades If you're talking about the displacement of a raster on grid, i think it's normal... depends of the processing of geometric correction. You can see more about that here: www.dgi.inpe.br/documentacao/arquivos/NiveisdeProcessamentoCBERSAMZ.pdf Note: I really recommend talk about this directly with INPE if it's really important |

Hello again, in the first moment I assumed that the both grid were equal, but reading the documentation is possible understand that the WPM sensor have a smaller grid. The MUX have 95km of width, while WPM have 92km. source: https://forest-gis.com/2019/12/novo-satelite-do-tipo-cbers-e-lancado-com-sucesso-na-china.html/ I will send a e-mail to INPE and ask about this information, when receive the feedback a post here the answer. Thanks. |

Hi, For MUX, CBERS4ASAT delineate a search for image based on path/row that should be the same in WPM. The Grid difference between MUX/WPM has no effect to the choose of the scene if you select an area totally or partially contained in the path/row. |

Hello everyone,
I'm working with the CBERS4ASAT and I did a script to do the download of multiples WPM level 4 scenes.
For write the first script I used the grid (and the path_row) of MUX sensor, that is similar, but not equal to the WPM grid. I need the shapefile of WPM GRID .
Someone have the WPM grid and can share with me?
thanks.
