![]() This way you can limit the processing required and run locally for faster results. Even if you are planning to save your raster in SDE, you might want to consider processing the mosaic into a file Geodatabase first.Before you start it’s recommended to try your approach with a subset of data to see how long it will take and if the quality of the results meet your needs. ![]() You can store the output to a file Geodatabase (can handle huge rasters, lots of viewers) or SDE (adds enterprise access and security). Using 7,600 uncompressed 4-band TIFF orthos, each 1km in size and 120MB (approx. Please note, if you have 10x, many newer options exist and I would recommend taking a good look before jumping into this approach (although still a viable option). “Mosaic Large Images to a Single Raster in ArcGIS” is a case study based on ArcGIS Desktop 9.3 with decent, yet older, hardware - then comparing some different compression options and visual results. ![]() While the new Mosaic Datasets are great, what if you only have 9.3 - here is one way to merge them together using the Raster Mosaic tools available in both 9x and 10x. I’ve had some question regarding large sets of ortho imagery tiles and how you can turn this into one seamless raster (and maintain performance).
