Peter, I can think of a few reasons, one for example, I have a geologic map that has only USGS quads for position reference. I also have a shapefile that has county outlines and another that has the PLSS land survey townships and section lines. I need a GeoTiff because one of the applications I use only will read a GeoTiff, so I want to "burn" the vector shapefile data into my raster GeoTiff image, so I can find the location of the outcrop I mapped, relative to section and township I was mapping in.

Why would you want to map a Shapefile into a Geotiff file? They are two fundamentally different types of spatial object. Shapefiles are exclusively vector in nature, whilst Geotiffs are exclusively raster. I suggest reading a text, such as Burrough and McDonnell, Principles of Geographical Information Systems, published by Oxford University Press, gaining an understanding of the different properties and how to exploit them. Then you will be able to choose a data format appropriate to your purposes. Peter. On 8 June 2015 at 15:10, Ronquillo, Edgar Nahum <[email protected]> wrote: > Hello Gdal users, > I have a question.
