I am hoping to come up with a script that would allow me to mosaic imagery into a polygon tile grid. My hopes is to do this with gdal or QGIS. I am wondering if anyone knows of an existing script, before I start. My first thoughts was to use gdal_merge, but I do not see a variable for using a polygon (shapefile) as the boundary. gdal_merge does have the -ul_lr function, so I know that it will work on subsets of images.
What I am looking to do is the following: From a source of ortho imagery, transfer any and all pixels that intersect with the tile grid, then move on to the next grid. There may be 10 source images (for example) that are large in size (geographic extent and disks space) that would be used to populate the individual grid tiles (ie: 1km X 1km).
Thanks….
