Python for Everyone – Free Python Training

Python for Everyone – Free Python Training

Python was introduced by Esri in ArcGIS platform version 9, and since then, it has been widely accepted as the scripting language of choice for ArcGIS users everywhere and continues to grow in popularity as more geospatial users start to understand the benefits of python scripting.

Python is an easy to learn, powerful language… (with) high-level data structures and a simple but effective approach to          object oriented programming. Python’s elegant syntax and dynamic typing…make it an ideal language for scripting…in many areas and on most platforms.” –python.org

Python for EveryonePython for Everyone is a free online self paced training course provided by Esri designed to help GIS analysts, GIS technicians, GIS specialists, data processors, and anyone else who is new to python and wants to learn how to write python scripts to automate their ArcGIS tasks.

It introduces users to the fundamental of python concepts while exploring the python scripting environment found in ArcGIS. It provides tips and techniques to help users master proper python syntax, script flow, and error handling.

Python for Everyone Will Teach You How to:

  • Choose the Python scripting environment that meets your needs
  • Choose appropriate data types and apply Python syntax rules when writing a script
  • Quickly create a script to automate a geoprocessing task using a Python snippet
  • Label map features using a Python expression
  • Understand common types of errors that can occur in a script and how to correct them

The courses assumes that you have either completed the ArcGIS Introduction to GIS course (also online and free) or have equivalent GIS & ArcGIS knowledge. To complete the course exercises, you also need to have ArcGIS for Desktop and PythonWin 2.7.  PythonWin is available as a free download and Esri offers a free 60 day ArcGIS trial if you do not already have acces to it.

Earth Observation for Water Resources Management

Earth Observation for Water Resources Management 400

Earth Observation for Water Resources Management

Earth Observation for Water Resources Management: Current Use and Future Opportunities for the Water Sector edited by Luis García, Diego Rodríguez, Marcus Wijnen and Inge Pakulski provides a series of practical guidelines that industry leaders can use to decide if remote sensing would be useful to solve their problems.

Water contributes to all aspects of economic and social development and although the use of remote sensing techniques for operational purposes in hydrology and water resources is not new, is has become a fast-growing industry.

“Water lies at the heart of economic and social development and is thus a critical factor in poverty reduction. Growing economies and populations require better water management to keep up with the demand for energy and food and to ensure access to safe water and adequate sanitation. Twenty-first century growth requires modern tools to help countries to understand their water challenges, risks, and options.

Remote sensing enables coverage over large areas and spans of time without heavy field personnel requirements, and its accessibility, reliability, and accuracy have improved dramatically in recent years. While both in situ and remote sensing measurements are subject to specific limitations, researchers have developed techniques that can combine or correlate data from both methods to benefit each other’s strengths.

Understanding the potential combinations of available options has been a challenge for many practitioners. For this reason, Earth Observation for Water Resources Management: Current Use and Future Opportunities for the Water Sector aims to shed light on the strengths and limitations of remote sensing in order to help specialists to provide decision makers with fast and reliable information.” Jennifer Sara, The World Bank Group

Earth Observation for Water Resources Management was the result of a collaborative joint effort involving the World Bank, the Commonwealth Scientific and Industrial Research Organisation, and the University of Arizona. It describes some key global water issues, perspectives for using remote sensing approaches, and why it is importance for water resources. The 11 chapter publication describes eight key types of water resources and various sensors that can help provide valuable information. The book concludes literature review on reliability statistics of remote sensed calculations.
