Writing advanced geoprocessing scripts using python for math

ArcGIS Pro

Calculate the maximum X-coordinate of a feature. This third example is a little different. Anyone with access to the file or geodatabase can run its tools. The idea, however, is for Python be a simple and sparse language, without a dense clutter of conversions to cover the rare case of an unexpected data type.

Variables can also represent other things, such as GIS datasets, tables, rows, and the geoprocessor that we saw earlier that can run tools.

In Python, classes are grouped together into modules. Values are returned from the function using a return statement.

Geoprocessing framework

For the record, the core geoprocessing tools and framework were all built using ArcObjects. You can create a model that contains a single tool, but embeds some of its parameters.

Python for ArcGIS

To get decimal output One of the numbers in the operation must be a decimal value: This gives you more control of the language itself. This applies to GIS and many other areas of computer science.

If you are new to Python scripting it can be helpful to see the concepts from another point of view. Rather than filling out these parameters each time you execute the Buffer tool, you can quickly create a model and set these three parameters, save it as the MyBuffer tool, and use its dialog box rather than the Buffer dialog box.

In some strongly-typed programming languages, such as Java, you would be required to tell the program that you were creating a numerical variable, but Python assumes this when it sees the 2. Your script attempts to run all of the code in the try block.

Readings We'll take a short break and do some reading from another source. Add Jelly In the object-oriented example, the bulk of the steps have been eliminated. There are functions to access the properties of ArcGIS data, such as the extent of a feature class or the sundry properties of individual fields on a table.

The script file name is populated for me. Access geoprocessing functions and objects. Spacing and indentation, which are important in Python, are also easy to keep track of in this interface.

This toolbar is visible by default.

Calculate Field examples

You might have noticed that the Python window helps you by popping up different options you can type for each parameter.
