Learn to write code for free in any GIS programming language part 1

GIS Programming in Applications – Python, C++, .NET, C#

Python has been a standard language in GIS because Esri and open source tend to gravitate toward it. Of all GIS programming languages, many consider it to be the front-runner.

In addition to Python, C++, C# and .NET languages exist in GIS:

C++ lets you work in multiple environments. While C# and the .NET languages offer you good development tools and interaction with Windows-based software.

We suggest to learn Python first because its usually the first language a company looks for.

Here are 3 bare-boned courses to start your journey into Python programming:

• Programming Foundation with Python (Udacity) – Actively learn to code in Python for free. (Programming Foundation with Python)

• GEO485 GIS Programming and Automation (Penn State Open CourseWare) – Learn to use the Python scripting language and automate GIS tasks in Esri ArcGIS desktop. (GEO485 GIS Programming and Automation)
• Python Scripting for ArcGIS (Esri) – Create custom geoprocessing tools and learn how to write Python code in ArcGIS. (Python Scripting for ArcGIS – Download data and PDF through Esri)

You won’t truly learn Python unless you apply it:

Build your own toolbox to manage, process or display GIS data of your own.

A good example would be to analyze a large Excel file. Import that data into ArcGIS and run an analysis on that shapefile with your Python script.

Flaunt your new skills on your portfolio page. Add to your CV that you have a working knowledge of Python programming.

The big advantage of using Python is this:

You automate workflow and repeat redundant tasks. If you can save a company time and money with a working example, you’re as good as gold.

If you get good at Python, it isn’t that hard to transfer your skills to JavaScript. This is the way to go for developing your own web mapping applications.
