The #1 reason why you might need to change NoData to zero is on the grounds that it’s difficult to calculate NoData value during a mathematical operation.
The way to convert NoData to zero for rasters in ArcGIS are:
Let’s take a closer look at these two methods.
You can change over no data to zero by using the “Reclassify Tool”. This instrument likewise requires the spatial examiner augmentation in ArcGIS.
This tool allows you to change old raster values to new raster values. Best of all, you can reclassify a range of values.
To go from no data to zero, enter “NoData” in the old worth field, and enter another value of zero.
*You may want to try the method above as the Con Tool may not return the correct output
With the spatial analyst extension, you can use the “Con Tool”, which means “contingent”. The Con Tool plays out a contingent if proclamation assessment on every framework cell of a raster dataset.
This capacity will permit you to supplant NoData values with 0 qualities, with the condition “value = NoData”.
The Reverse: Set Null Tool
Here’s a case of changing raster esteems to “NoData” using the Set Null Tool:
Under Spatial Analyst Tools > Conditional, double-tap the Set Null tool. The “Input Conditional Raster” will be the raster you need to set invalid. The “Info False Raster or Constant Value” will be a similar raster. The articulation will figure out which esteems you will need to make invalid in your dataset.
Here’s an example of using the “Set Null” tool:
The result of using this tool will turn all values of 4 as “No Data” as seen below:
