Re: [gdal-dev] ESRI text format?

the text is a edit-session from ArcGIS. ogr2ogr can't read this.


In this case, I need to write it, but thanks -- I'm sure the same applies.

Sure, and that's what I've done, but then OGR is not writing it, I am 
writing it with Python -- which I agree is not that big a deal but still 
harder than one command line with ogr2ogr.


It doesn't really sound like this is a "format" that it would make sense 
to support -- which is probably why OGR doesn't support it.

Obviously lots of the KML info would be lost, but I'm just thinking
something simple.

[gdal-dev] Draw KML/SHP with OGR?

[Ryan McKinley]

Is it possible to render KML or SHP to an image using OGR/GDAL?
Obviously lots of the KML info would be lost, but I'm just thinking
something simple.

If not, any pointers?  (For SHP, we could use geotools)

Thanks

Re: [gdal-dev] gdalwarp -dstnodata

[Benoît Andrieu]

Hi Sven,

It's not the role of gdalwarp to tell the color to be rendered with no 
data values.
In your example, gdalwarp tells the renderer to display the pixels with 
values equal to 255 with a color specified by the renderer.

It only adds in the tif files a tag that set the white color as transparent.

For example, with Mapserver as a renderer, you will set in the mapfile 
the background color as white (IMAGECOLOR 255 255 255).


What software are you using to view your files ?
What is the color in the source file that you want as transparent / white ?

Regards,

Benoît

Hi,
I use the gdalwarp utility to transform geotifs:

gdalwarp -co compress=lzw -s_srs "+proj=tmerc +lat_0=0 +lon_0=6 
+k=1.00

+x_0=250+y_0=0 +ellps=bessel +units=m
+towgs84=590.1181,99.6226,340.1890,1.185095,-1.334952,-2.904521,16.51559" 
-t_srs

"+proj=utm +ellps=GRS80 +datum=WGS84 +zone=32" -dstnodata 255
bbp07231053_2559-wla_0053-1a.tif out/bbp07231053_2559-wla_0053-1a.tif

I want to convert the new "nodata-areas" to be displayed in white (255 
255

255)
if I try -dstnodata 255  or -dstnodata "255 255 255" in every picture 
the no

data areas have other colors but not white. What can I do?

Thanks
Sven
