| Together the netCDF interfaces, libraries, and formats support the creation, access, and sharing of scientific data.

The code below reads the global temperature data from file, computes the maximum and minimum temperatures and plots (using the matplotlib package) the. If the command > python -c 'import netCDF4' does not return any error, we have the package installed. Click Finish to create the feature class.Code (using netcdf4-python) Here we use the netcdf4-python package to read the data file.Repeat steps a through d for each field you want to add to the feature class.If you don't want any null values stored in the field, click the field next to Allow NULL values and choose No from the drop-down list.Optionally create an alias for this field by clicking in the Alias field under Field Properties and typing an alias.Click in the Data Type column next to the new field's name and choose a data type from the drop-down list.Click the next blank row in the Field Name column and type a name.You can click Import and import the field definitions from an existing feature class or define each field using the following steps:

The ObjectID value is populated automatically when you load data into the feature class through ArcGIS or insert records by editing a feature service that contains the feature class. Therefore, ArcGIS automatically adds an ObjectID and shape fields to the feature class.

Define the fields for your feature class.Īll feature classes must contain a unique identifier field and a spatial field.

You can browse the folders to find the coordinate system you want, or use the search to find it.

Choose a coordinate system for your data.

Click Next to proceed to the next dialog box.

If you want your table to store three-dimensional data, check Coordinates include Z values.

If you want your table to store measure values, check Coordinates include M values.

If your database has more than one SQL spatial data type available, use the Native spatial type for geometry drop-down menu to choose the data type to store your feature data.

Choose the type of features to store in the table: either Polygon Features, Line Features, Point Features, or Multipoint Features.

Right-click the table, point to New, and click Feature Class.įeature class names must start with a letter and cannot exceed the maximum number of characters the DBMS allows for table names. Start ArcCatalog or ArcMap and open the Catalog window. You can create feature classes (spatial tables) in your database when you connect to it from ArcMap provided you have the required database permissions to create a table and your database supports a SQL spatial data type.įollow these steps to create a feature class in a database from ArcMap or ArcCatalog:
