You can convert no data to zero by using the“Reclassify Tool”. This tool also requires the spatial analyst extension in ArcGIS. This tool allows you to change old raster values to new raster values. The best part is that you can reclassify a range of values. To go from no data to z...
In general, NDVI uses two properties to quantify healthy vegetation. It uses near-infrared (NIR) becausevegetation strongly reflects it. And it also uses red light, becauseplants strongly absorb it. For this same reason, this is why our eyes see vegetation as the color green. Now that you ...
Step 3. Reclassify Your Image to 0’s and 1’s The nit-picky ArcScan doesn’t like your 256 color scans. It wants zeros and ones. So this means you’ll have to reclassify your image using theReclassify Tool. Admittedly, this will come with a bit of trial and error. For example, h...
If you want tolearn how to vectorizeacontinuous raster, this will take a bit of effort to reclassify cells essentially grouping them into discrete forms. Using a temperature raster as an example, when you group values from [-37.8 to 0] as 0 and [0 to 37.7] as 1, you are turning it ...
