Expression: "Value = 1" Input true raster or constant value: Input false raster or constant value: InRas1. Output raster: NullTo_Ras. In the first step, IsNull gives the NoData areas a value of 1 and the non-NoData areas a value of 0. In the second step, for cells where the input conditional raster is true (value of 1), the output value is Identify the NoData locations with the IsNull tool: Input raster: InRas1. Output raster: OutNullRas. Use Con on the results to give the original NoData areas a value: Input conditional raster: OutNullRas. Expression: "Value = 1". Input true raster or constant value: . May 02,  · How to: Set raster values to NoData easily in ArcGIS Run the Spatial Analyst -> Conditional -> Set Null tool 2. Set the input conditional raster to be the raster dataset which you want to change 3. Set the expression to VALUE = where is the value that you want to replace with NoData. 4. Set the Input false raster or constant value to the same raster dataset that you select in .

ArcGIS offers a couple options to convert NoData values to another constant, such as zero. One option is to use the Spatial Analyst Con. Using the Is Null in conjunction with the Con tool, you can change NoData values on a raster to any desired value while retaining the original non-NoData. Cell values can be either positive or negative, integer, or floating point. Cells can also have a NoData value to represent the absence of data. Sometimes there. Similarly, Set Null is often used to change all values that meet a specified condition to NoData. It can be used for processing the remaining selected cells. Change raster cell values from NoData to Zero in ArcGIS? Going from NoData to Zero can be done in several ways in ArcMap. As you have reclassified this raster I'll assume that you have access to the Spatial Analyst extension, so will continue with instructions that. Set the expression to VALUE = where is the value that you want to replace with NoData. 4. Set the Input false raster or constant. Let’s say that you have three raster datasets. You want to calculate statistics by using the sum function with raster calculator. If one of the raster datasets containing NoData values, this may give you erroneous raster calculator values. In this case, you may want to change NoData values to 0. Apr 26,  · When I created the raster from an XY table (text file) ArcMap set the NoData value to the default e+ However, I am trying to calculate zonal statistics for the raster dataset and want NoData values to be ignored in the minnesotamomentum.coms: 3. May 02,  · How to: Set raster values to NoData easily in ArcGIS Run the Spatial Analyst -> Conditional -> Set Null tool 2. Set the input conditional raster to be the raster dataset which you want to change 3. Set the expression to VALUE = where is the value that you want to replace with NoData. 4. Set the Input false raster or constant value to the same raster dataset that you select in . The fastest way to convert NoData value to 0 in ArcGIS is to use map algebra with the Con operator. Con(IsNull(your_raster), O, your_raster) Now if you want to avoid creating those NoData values when you extract some values and there is no simple conversion rule, you can use the "reclassify tool" making sure that you have an output value (which can be zero) for each input (even for NoData). Setting values to NoData with Set Null. In particular, the logical tools in the Math toolbox can be used, with the Test tool being particularly useful. Similarly, Set Null is often used to change all values that meet a specified condition to NoData. It can be used for processing the remaining selected cells, to create a . Expression: "Value = 1" Input true raster or constant value: Input false raster or constant value: InRas1. Output raster: NullTo_Ras. In the first step, IsNull gives the NoData areas a value of 1 and the non-NoData areas a value of 0. In the second step, for cells where the input conditional raster is true (value of 1), the output value is Nov 28,  · Summary. ArcGIS offers a couple options to convert NoData values to another constant, such as zero. One option is to use the Spatial Analyst Con (conditional) tool to convert NoData values. This can be called through the Spatial Analyst toolbox directly or used in conjunction with the IsNull tool in Raster Calculator. Identify the NoData locations with the IsNull tool: Input raster: InRas1. Output raster: OutNullRas. Use Con on the results to give the original NoData areas a value: Input conditional raster: OutNullRas. Expression: "Value = 1". Input true raster or constant value: .
