Synopsis

AFL% eo_arrays();

Result

Returns a one-dimensional table-like two attribute array with rows for individual referenced arrays where the first attribute gives the name of an array. The second attributes represents the setting of an array as a string, i.e. whether it has spatial (‘s’), temporal (‘t’), or vertical (‘v’) references.

Examples

1. Create a spatial and a spatiotemporal array ``` store(build([lat=0:179,256,0,lon=0:359,256,0],double(random()) / double(2147483647)),world_s);
   eo_setsrs(world_s,‘lon’,‘lat’,‘EPSG’,4326,‘x0=-180 y0=90 a11=1 a22=-1’);

store(build([lat=0:179,256,0,lon=0:359,256,0,t=0:364,32,0],double(random()) / double(2147483647)),world_st); eo_cpsrs(world_s,world_st); eo_settrs(world_st,‘t’,‘2001-01-01’, ‘P1D’);

2. List all earth observation arrays

eo_arrays();

3. Listing only spatiotemporally referenced arrays

filter(eo_arrays(),setting=‘st’);

4. Clean up

remove(world_s); remove(world_st); ```

Notes

Vertical referencing is currently not implemented.
