ediring pixels in raster


Recommended Posts

Guys,

I have a raster that contains only two values, 0 and 1. The zero values represent the land area whereas 1 is water. There are some land pixels that I need to 'erase'. Anybody knows how to do that in Idrisi or other software perhaps. I tried ArcScan but the Raster Painting toolbar is inactive, even after I start editing the raster layer. I could not understand why.

Anybody willing to throw some light?

Thanks! :)

I can use the eraser tools but the erased pixels keep on coming back.

Anybody willing to help?

Thanks.

Using ArcScan in ArcGIS:

note that:

***** The only supported formats for Raster Cleanup are TIFF, IMG, and GRID

***** enable arcscan extension

1 - Put a featureclass in the dataset you have the image, add it in arcmap

2 - Start editing the featureclass by editor toolbar

3 - in the arcscan, start cleanup

;)
