Problem with ASTER terrain data

Postby 469711868 » Wed Sep 07, 2016 8:25 pm

Hello all

I've download the ASTER data and transfer to bil also.
But I only can use one bil file at one time for very small domain.

Can someone tell me how to set index file for multi-til files?
I tried to set index file like the one in the topo_30s, but didn't work.

Thanks!

Here's my index file for one til:

type = continuous
signed = yes
projection = regular_ll
dx = 0.00027777778
dy = 0.00027777778
known_x = 1.0
known_y = 1.0
known_lat = 0.0
known_lon = 111.5
wordsize = 2
endian = little
tile_x = 10799
tile_y = 10798
tile_z = 1
row_order = top_bottom
missing_value = 32768
units = "meters MSL"
description = "ASTER 1-sec Topography Height"

my first til name is 00001-10799.00001-10798, second til in 10800-21599.00001-10798
Second til domain is on right of first til domain.
It works on 1 til.

Can someone help me? Thanks

your problem is that the tiles are not of equal size. Double check your x dimensions again.
