Hi, 

 

 

i might be missing something fairly obvious, but i want to read standard ESRI GRID rasters into FME, work with them and write a single ESRI GRID raster. (Not DEM, GeoTIFF etc etc, just standard GRID).

 

 

Do i have to convert the GRID to ASCII in Arc before FME can read it? and is this the case for writing too?

 

 

thanks for any help

Hi,

 

 

I dont usually work with ESRI grids, but this reader (http://docs.safe.com/fme/html/FME_ReadersWriters/Default.htm#arcviewgrid/arcviewgrid.htm) seems to me what you are looking for.

 

To write ESRI grids is only possible with the Esri ASCII Grid Reader/Writer (http://docs.safe.com/fme/html/FME_ReadersWriters/Default.htm#esriasciigrid/esriasciigrid.htm) ( I think)

Hello. Whats the file extension of the grid? For .asc or .grd use the esri ascii grid reader/writer

thanks for your answers, 

 

 

I'm working with ESRI GRID which is actually a collection of .adf files with a metadata xml. the ASCII writer will be useful as eventually i'll want an ASCII but for the reader, i need to work with the actual GRID files. 

 

 

the ArcGIS Binary Grid (AIG) reader is interesting and i'll try and work with that, cheers

unfortunately you cant write to ArcGIS Binary Grid (AIG) but hopefully this should work overall
