Need help with TIF TILE SIZE

[Yar Doroshenko]

Brent,

I have tried the mosaicking feature of gdalwarp. I tried it on 5 images out
of the 52 that I have. I started with the

gdalwarp -s_srs "+proj=utm +zone=15 +datum=NAD83" -t_srs "+proj=latlong
+datum=WGS84" 10_1_1.tif latlong.tif

on the top left image, and then I did

gdalwarp -s_srs "+proj=utm +zone=15 +datum=NAD83" 10_1_2.tif latlong.tif
gdalwarp -s_srs "+proj=utm +zone=15 +datum=NAD83" 10_1_3.tif latlong.tif
gdalwarp -s_srs "+proj=utm +zone=15 +datum=NAD83" 10_1_4.tif latlong.tif
gdalwarp -s_srs "+proj=utm +zone=15 +datum=NAD83" 10_1_5.tif latlong.tif

to the four consecutive images on the right.  I next tried to display them
and what I got seemed like the first image with somewhat distorted edges.

Should I start with a center image first? Would these instructions only
work for 5 images (1 centerpiece and 4 border images)? How should I handle
the 52 ones? They are arranged in a rectangular pattern.


Thank you,


Yar
