 Hi, I'm Jim Detweiler, a member of Penn State's online geospatial program faculty, and I'm here to talk to you about our course in web application development for the geospatial professional. This course involves creating web mapping apps, specifically using software from a leading GIS vendor, ESRI. So if you work for an organization that uses ESRI web GIS products, such as ArcGIS Online or ArcGIS Server, then this would be a great course for you. On the other hand, if you want to learn about this topic using free and open source software, then I would point you towards our course entitled Open Web Mapping. So this course starts out with learning how to work with tools for developing apps that require no coding at all. And for some of you, that could be the most important takeaway from the course. But the bulk of the course is around writing code in JavaScript that works with ESRI's JavaScript application programming interface or API. Specifically, we work with version four of the API, the latest release, which has some really cool features, including the ability to develop 3D apps without the need for any kind of special browser plugin. So as you work through the course, you will complete a number of assignments that I prescribe that I give to you. But by the end of the course, when you get to the final project, you'll be able to pick whatever application you want to develop, and that will be a great way for you to tie together everything that you've learned in the course. So with that, thank you for watching, and I hope to see you in the course.
