I've got a large number of raster tile and would like to create a list that shows how many have a certain nodata value,for example,how many have a nodata value of o,how many have a nodata value of -39 to -1 and how many have a nodata value of <= -40.What would be the best way to do this?
I've tried a few different methods but so far have only ended up with empty csv files.
Thanks.
Because most data formats do not understand fme lists.
Assuming you list is in the format _list{}.value,_list{}.count,try using a ListExploder just prior to the CSV writer,and set the attributes on the csv to value and count.
To get your your data into that format,use the RasterBandPropertyExtractor as@DaveAt亚搏在线Safesuggests,and follow that by the StatisticaCalculator with ComputeHistograms selected.
Hi @jamesclarke,
The RasterBandPropertyExtractor transformer will give you the NoData values for each band,in the list _band{}.band_nodata.You can use ListSearcher transformers to separate the rasters by NoData value.
