[gdal-dev] gdal_rasterize

[Jason Mathis]

All right I think I fixed it. 

I created a centos vm and installed gdal from yum and everything worked fine. Which made me very suspect of my box:( 

I have been using an older version of the postgres.app that comes with postgis and apparently some gdal binaries. I realized when I did a “which gdal_rasterize” that I was pointed at the postgres.app binaries. In the past I had installed binaries from kyngchaos’ site

http://www.kyngchaos.com/software:frameworks

so all I needed to do was: 

export PATH=/Library/Frameworks/GDAL.framework/Programs:$PATH

to point at the binaries from the kyngchaos’ install and now I have run my script several times without error. Some thing before I couldn’t do even once. I was using an older postgres.app so upgrading that could have solved the issue as well. May try that later but so happy it running good now! 

Thanks for the responds but I believe I am good to go.

Well that was easy. You can use the attached shape file, I can certainly reproduce the error no problem. I am currently bringing up a centos vm to see if it has the same behavior. 

Here are the commands to reproduce:

gdal_rasterize -a region -where "region='0'" -burn 2  -ts 1000 1000 countries.shp countries.tif
gdal_rasterize -a region -where "region='2'" -b 1 -burn 3 countries.shp countries.tif
gdal_rasterize -a region -where "region='9'" -b 1 -burn 4 countries.shp countries.tif
gdal_rasterize -a region -where "region='19'" -b 1 -burn 5 countries.shp countries.tif
gdal_rasterize -a region -where "region='142'" -b 1 -burn 6 countries.shp countries.tif
gdal_rasterize -a region -where "region='150'" -b 1 -burn 7  countries.shp countries.tif


thanks,

That maybe difficult, not sure I can share the shapefile I am using. Although I could try and find a sample and reproduce the error; if I can. 

Are you thinking this could be data related? 

I will respond when i can reproduce. 

Thanks!

Jason,

Can you provide some sample data to reproduce the error?

Hi all was wondering if anyone could help out here. I have been trying to rasterize a shp file using gdal_rasterize and I keep getting an error I have no idea about.


gdal_rasterize(1844,0x7fff7a393310) malloc: *** error for object 0x7f8f40d032e0: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug


the command I am using is:
gdal_rasterize -at -burn 1 -a $attribute -where “$attribute=‘value'" -ts 5000 5000 $shapefile $outfile


version is: 
GDAL 1.10.0, released 2013/04/24

I am running os x 10.9.2.

It seems to happen randomly. I have about 10 different values I need to get out. Not sure what other info would be useful so please let me know. 

thanks!
