Re: [gdal-dev] confused about using gdal_rasterize

2011-01-26 Thread Chaitanya kumar CH
Ahmet, Transparency can be easily set using the alpha channel in RGBA images. Use the -init option to set the background to transparent. Make sure this is equal to the value set as nodata. You can set the nodata value using the -a_nodata option. Make the rasterized areas visible by setting the

Hi All, The File Geodatabase API - Beta is now open. [1] Accessing the api download and fgdb-api forum requires an ESRI global account (free). The licensing agreement is voluminous, almost 5 thousand words.[2] I've scanned through it as best I could looking for show-stoppers. I don't _think_

Hi Frank, so it seems like the data is there after all. Ah. I suspect this is a problem with having both an .aux and .aux.xml file. I suppose the .aux file is being used and the .aux.xml file is ignored. Try moving the .aux file somewhere out of the way and see if things behave more properly.

Hi Frank, If you can make the dataset available I might be able to improve the robustness of the logic for the case with a .aux and .aux.xml file. Here's a link to the dataset from my dropbox account: http://dl.dropbox.com/u/938865/ENR_P01.zip Best regards, -- Fernando Cacciola SciSoft

[gdal-dev] General geotiff question

2011-01-26 Thread Fernando Cacciola
Hi, I have a general question (and I don't know where else to ask, sorry if this is off-topic) Can I assume that in practice the transformations from PCS to raster space are lineal? That is, cropping a TIFF given 4 lat/lon corners amount to *simply* mapping the corners to (x,y) pairs?
