I want to see how much geospatial solution for a project we can get just by me asking about it, I will use R as the foundation for code.
I want to create a series of grids in (relevant) UTM zones for the terrestrial Australian Antarctic Territory, this consists of the entire Antarctic continent betwen 44E longitude, and 160Elongitude and offshore islands (Macquarie and Heard and McDonald islands at least). The latitudinal range then is at least 70S latitude to 50S (I'm not concerned for now for regions further south as that has implications for using UTM vs something like polar stereographic, I'll keep that as a todo/explore - it might be MGRS).
Because we start with UTM that means each zone is consistent within itself, but there will be some overlap/duplication at zone edges. I won't be rendering every theoretical tile, because only terrestrial (for now). There will be two levels of detail, one targeting pixels at 60m resolution, and one at 10m resolution. The idea is that any "scene" that I render of imagery data at either resolution fits into a larger grid that covers every area of interest. The finer resolution grid should be tiles of 6000x6000m, and the coarser be 36000x36000m.
The finer grid should nest in the coarser one exactly and have a system of identifying tiles for a given UTM zone that is global (for that zone). Scenes that are to be actually materalized will be those that intersect land, reefs, ice shelf, or more persistent sea ice close to the coasts, but all that will be defined by input data. For now I want to design the abstract grid specification.
I've chosen 60m pixels because the extended area of Heard and McDonald Islands (and its reef, and offshore Shag rock) are a convenient unit of area that gives an overall image at 60m resolution that is about the same dimension (number of pixels) as the individual 6000x6000m (10m) scenes. So, the coarser grid will be composed of regions that are about that same size. I'd like to discuss how to plan out the requirements and design.
