convert shape to raster (.BIL)

[Viviane Deslandes]

Hello, I need urgently convert a vegetation map of shape format (.
shp) for raster, necessarily in the extension. BIL. I tried in
ArcMap, but I not have sucess.... Can someone help me? This is the
only format that open in a software that I need to use.

Thank you

Viviane

Hi Viviane,

In ArcGIS 10, one way to do this is to convert your shapefile to a raster
with Arc Toolbox > Conversion Tools > Polygon to Raster, and give the output
file a .BIL extension.

In Arc 9.3 you can convert the shapefile to raster through the Spatial
Analyst dropdown menu. Be sure to set your Spatial Analyst Options so that
your desired output extent/cell size and file location are set correctly). I
don't have 9.3 anymore so I can't be 100% sure of the process now... Once
you have it in raster format, check the Arc Toolbox > Conversion options,
and look for a tool that converts b/w raster formats.

Hope this helps.

If you can't find it, feel free to send me the shapefile and I'll convert it
for you.

John

Thank you

Viviane

Another potential solution, once you've converted the shapefile to a
raster format that's supported by your GIS software, is to then
convert that raster to a .bil with the opensource gdal tools. Download
and install FWTools (http://fwtools.maptools.org/), then run:

gdal_translate -of EHdr "c:\path\to\raster" "c:\path\to\output
\file.bil"

from within the FWTools2.4.7\bin directory. The "-of EHdr" flag
specifies an output format of EHdr = ESRI Header labelled = .bil
(http://www.gdal.org/frmt_various.html).
