I have produced ASCII files in MaxEnt. These files are able to be loaded into Arcmap10.1 and display as an image, but I cannot interpret them or create them into a polygon for further analysis. I have read some forums that say I need to add spatial reference and calculate statistics (http://gis.utah.gov/wp-content/uploads/ASCII_Elevation_Data.doc) but when I do this to the original file and then import it will not create the resulting raster into a polygon, stating that "The environmental window is ignored"
Ideally, I need to add all the different environmental considerations to the ASCII file and then import it as a raster. This will allow me to analyse it and then create a polygon of the extent of the layer i am looking at.
Can anyone suggest a series of steps to overcome this and produce a raster and then a polygon?
