Hello Dear GIS users.
Could you please advise with question regarding BAG file?
- We are starting work with BAG format. We have Fledermaus and ArcGIS. Input data is x, y, z gridded file (0.5x0.5 meters). We calculate uncertainty using special order, after that export to BAG. When we compare in ArcGIS GeoTIFF from Fledermaus and BAG from Fledermaus we can see shift between them about 60-65 cm (See attached file).
- What is the standart for BAG creation? I checked Fledermaus and CARIS software. And I have 2 different BAG files. Support team from QPS and CARIS tell me that is different method of grid creation. I can't understand why we have this difference and shifts, as I understand BAG file is format to exhange data between software.
Look forward
regards,
Anzhelika
either your extents are different or they use a different method of referencing the grid. esri uses the center of the cell to denote position when creating rasters, other software may use a different location. In any event, they seem to be shifted by 1/2 cell size in the x and maybe 1 in the y direction. You will need to confirm the extents and cell sizes. Also, in arcmap, it is wise to use a snap raster to ensure that cell edges etc align properly
