Courses

All of my courses are available on the Udemy platform. This means that

  • They are self-paced. Start when you want and take as long as you want to finish
  • They are available 24-7 on-line
  • They can be downloaded to a mobile device and watched off-line
  • They have life-time access
  • The price is $20 each for readers of this blog.

All of my courses use open source software and simple, standard methods that have stood the test of time. They can be implemented without spending anything on licensing, subscriptions, or per-user fees.  Many of the concepts you will learn can be applied to commercial software as well but I think you will be impressed with the power and ease of the open source ecosystem, especially for multi-user geospatial applications.

Web Programming courses for Geospatial

  1. Introduction to web programming for GIS applications – This course is the foundation on which all my other web programming courses are based on. Its purpose is to provide the background necessary to understand the big picture of how various technologies, from basic HTML to PostGIS databases, work together to form a web GIS application. This course is intended to be watched with the intention of understanding the big picture. It is not intended to be followed along step by step, although several people have been able to do so.  (13 hours) AVAILABLE NOW.  *** BESTSELLER ***
  2. Display and analyze your GIS data on the web with Leaflet – This course builds on the first half of the previous course and provides much more detail on the Leaflet.js API and the Turf.js API for spatial analysis. Students are expected to follow along on their own computers and build a web map from start to finish. This course only covers client-side technologies, i.e. displaying and analyzing static data. It does not cover creating and/or editing data via the web although that subject is introduced in the introductory course. (13 hours) AVAILABLE NOW.     *** BESTSELLER ***
  3. Mobile GIS and mapping applications with Leaflet – This course builds on the previous two to cover issues specific to mobile devices, This includes dealing with small screens, touch screens, accessing the devices sensors, and working off-line. (4 hours) AVAILABLE NOW $15 until August 31
  4. PHP registration, login, and content management system – One of the most frequent questions that I get is “How do I control access to my web pages and content?”. This course attempts to answer that question by providing step-by-step instructions for developing a user registration, login, and content management system that you can use for your own projects as-is or modify to suit your purpose. (9 hours) AVAILABLE NOW
  5. Server based web gis applications with Leaflet and PostGIS – This course will build on the introductory course to provide much more detail on integrating Leaflet web maps with a spatial database. It covers server-side programming with PHP, AJAX, and SQL. This is necessary for applications where the user is allowed to create and/or edit data via the web. Although I use Leaflet and postGIS as examples in this book the concepts are easily transferable to any client side web mapping API that can display GeoJSON and any server-side database. (16.5 hours) AVAILABLE NOW.
  6. Mobile data collection applications with Leaflet and PostGIS – This course will build on the previous course and show how to develop applications for collecting data in the field using the devices GPS sensor. AVAILABLE NOW 

QGIS and PostGIS courses

  1. QGIS 3.0 for GIS Professionals – This course is projected to be available concurrently with the release of QGIS 3.0 It will provide an overview of QGIS specifically for GIS users who are already trained in the use of commercial GIS software. Over 10 hours of content. AVAILABLE NOW!!! *** BESTSELLER ***
  2. Spatial databases with QGIS and PostGIS – This course is intended to provide an introduction in using spatial databases (based on PostGIS) for storing and analyzing geospatial data through SQL commands Over 10 hours of content. Available NOW!!!    *** HIGHEST RATED ***
  3. Survey of python for GIS applications – This course will provide a review of the python language and the python ecosystem for data analysis and geospatial applications. This course teaches PYTHON, not a particular library such as ArcPy or PyQGIS, but I think you will be impressed with what you can do with pure python not tied to a particular desktop GIS software and if you do decide you really want to work with ArcPy or PyQGIS you will have a strong basis for learning those libraries.  Available Now

Spatial analysis in Leaflet with Turf.js (Part 3 – Line intersection)

In this video I demonstrate how to use  Turf.js to  return the intersection of lines and polygons.  There is not a straightforward way to perform this analysis in Turf.js but Turf.js is better thought of as a toolbox than a packaged solution. And turf.js does provide a number of tools that can be used in conjunction to perform this analysis. Continue reading “Spatial analysis in Leaflet with Turf.js (Part 3 – Line intersection)”
