![]() ![]() The calendar attribute values noleap and 365_day, assigned to the time coordinate variable of the netCDF file, are not honored in ArcGIS. Youll then change the display by selecting a different time step. This exercise will take approximately 15 minutes to complete. ![]() To render the output as a voxel layer, it must be added to a local scene with the same horizontal and vertical coordinate system as the netCDF file. To save the output layer, right-click the layer in the ArcMap table of contents and click Save As Layer File, or use the Save To Layer File tool. Youll locate the Make NetCDF Raster Layer tool and create a raster layer using a variable from a netCDF file. Exercise 1: Displaying a raster layer from a netCDF file Youll locate the Make NetCDF Raster Layer tool and create a raster layer using a variable from a netCDF file. The Output netCDF file parameter will not automatically add layers to the map or scene. You can use these tools to make a netCDF raster layer, feature layer, or table view to convert to netCDF from a raster, feature, or table and to select a dimension of a netCDF layer or table. This tool can be used to make a temporary layer, so you can work with a specified subset of bands within a raster dataset. The layer created by the tool is temporary and will not persist after the session ends unless the layer is saved to disk or the map document is saved. The first value of a nonspatial dimension is used to create a default view of a multidimensional variable. Creates a raster layer from an input raster dataset or layer file. For example, you have a mosaic dataset that contains 30 years of monthly precipitation data, and you only want to extract data for each January to see how precipitation has changed for that month. They are not listed in the Dimension Values parameter drop-down list and cannot be set as the value of this parameter in a script.īand dimension is specified to create a multiband raster. This tool creates a multidimensional raster layer from a multidimensional raster or mosaic dataset by extracting a subset of variables. The first variable in the netCDF file suitable for creating a raster is selected as the default variable.Īuxiliary coordinate variables are listed in the X Dimension and Y Dimension drop-down lists and used during execution if specified. The output raster layer type is either float or integer based on the netCDF variable type. If the coordinates are unequally spaced, create a netCDF feature layer, then interpolate to raster. This layer will include any selections or joins already set on the layer. For each iteration, the tool returns the following outputs: Output Layer The layer from the map based on the parameter filters that have been set. To create a netCDF raster layer from a netCDF variable, the spacing between x-coordinates must be equal and the spacing between y-coordinates must be equal. To work with feature or raster tables, set the Layer Type parameter to Feature Layer or Raster Layer, respectively. ![]()
