Hi<br>I just did what you have told me and I got this error:<br><br>usage: Usage: gdal2tiles.py [options] input_file(s) [output]<br><br>gdal2tiles.py: error: Please convert this file to RGB/RGBA and run gdal2tiles on the result.<br>
<br>From paletted file you can create RGBA file (temp.vrt) by:<br>gdal_translate -of vrt -expand rgba /home/anrr/NDVI_rescaled2.tif temp.vrt<br><br>Any tips?<br><br><div class="gmail_quote">2011/10/28 Chaitanya kumar CH <span dir="ltr"><<a href="mailto:chaitanya.ch@gmail.com">chaitanya.ch@gmail.com</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Kat,<br><br>Your input image is of 32-bit float type. Whereas KML tiles are supposed to be png format that should be viewable on browsers.<br>
The corrupted pixels are a result of clipping the float valued pixels to the range [0,255].<br>
<br>I suggest scaling the pixel values to byte type using the -scale option in gdal_translate.<div><div></div><div class="h5"><br><br><div class="gmail_quote">On Fri, Oct 28, 2011 at 7:34 PM, katrin eggert <span dir="ltr"><<a href="mailto:katrineggert1980@gmail.com" target="_blank">katrineggert1980@gmail.com</a>></span> wrote:<br>
