Learn how to develop your own HTML5 GPS data collection applications that work like a native app on your mobile device. While there are many canned options available for mobile data collection that may meet your needs, there are also many times when it may make sense to develop your own for the following reasons.

Server-side web GIS applications allow you to build secure, web-based portals to your GIS data that allow display, analysis, and editing of GIS data from anywhere there is an internet connection. This is demonstrated with open-source software so that the concepts are accessible to everyone without cost. If you prefer to use commercial software I think you will still benefit from this course as the core concepts apply to both.

One of the most frequent questions I get about web programming for GIS is “how do I control access to my web maps and protect my data?”. Its a very important question for web GIS applications that allow online editing because you certainly would not want everybody with internet access to be able to edit your GIS data. Even if your web application doesn’t provide editing capabilities there is often a need to control access to it. Some data may be sensitive, such as the location of endangered species activity or critical infrastructure. Other data is proprietary information that cost you or your client a lot of money to collect and thus you need to prevent competitors from accessing it.

Thanks for your interest in this course. I’m very excited to release it as I believe that the combination of QGIS 3.0 and PostGIS amounts to an open-source “Killer App”. It solves many frustrating problems that I had to deal with throughout my career as the GIS specialist for small to medium sized environmental consulting companies. I think it is equally applicable to any organization that is outgrowing single-user desktop GIS but unable to pay the ten’s of thousands of dollars required to move into multi-user enterprise databases with commercial GIS software. It took quite a bit of effort to learn how to do this on my own and my hope, as always, is to help others navigate this technology without repeating the mistakes I made.

It’s a great time to be a GIS Professional. The industry is booming, ArcGIS Pro is a complete overhaul of ESRI’s desktop GIS product. Radian Studio is busy rewriting GIS algorithms to take advantage of massively parallel processing in modern computer architectures that can make short work of computer intensive spatial operations. Meanwhile in the open source world, the community of QGIS users is very close to releasing a major new version in QGIS 3.0. Continue reading “New Course: QGIS 3.0 for GIS Professionals”
