Welcome to the last course of the specialization (unless your continuing on to the capstone project, of course!). Using the knowledge you’ve learned about ArcGIS, complete technical tasks such raster calculations and suitability analysis. In this class you will become comfortable with spatial analysis and applications within GIS during four week-long modules: Week 1: You'll learn all about remotely sensed and satellite imagery, and be introduced to the electromagnetic spectrum. At the end of this week, you'll be able to find and download satellite imagery online and use it for two common types of analysis: NDVI and trained classification. Week 2: You'll learn how to use ModelBuilder to create large processing workflows that use parameters, preconditions, variables, and a new set of tools. We'll also explore a few topics that we don't really have time to discuss in detail, but might whet your appetite for future learning in other avenues: geocoding, time-enabled data, spatial statistics, and ArcGIS Pro. Week 3: In week three, we'll make and use digital elevation models using some new, specific tools such as the cut fill tool, hillshades, viewsheds and more. We'll also go through a few common algorithms including a very important one: the suitability analysis. Week 4: We'll begin the final week by talking about a few spatial analyst tools we haven't yet touched on in the specialization: Region Group to make our own zones, Focal Statistics to smooth a hillshade, Reclassify to change values, and Point Density to create a density surface. Finally, we'll wrap up by talking about a few more things that you might want to explore more as you start working on learning about GIS topics on your own. Take Geospatial and Environmental Analysis as a standalone course or as part of the Geographic Information Systems (GIS) Specialization. You should have equivalent experience to completing the first, second, and third courses in this specialization, "Fundamentals of GIS," "GIS Data Formats, Design, and Quality", and "Geospatial and Environmental Analysis," respectively, before taking this course. By completing the fourth class you will gain the skills needed to succeed in the Specialization capstone....

The course contents are up to date and equip the learner to face the real world of Remote sensing and GIS. I encourage those who still hesitate to get enrolled to make their decision soon.....

Whilst the material in the course is fine (although repetitious in places), the pacing is fairly poor.

Ultimately, there are three things covered by this course: a brief overview of remote sensing, hands-on raster classification and hands-on work with Model Builder work (using hydrology as an example framework). These then combine into the final submitted assignment. Many of the remaining lecture topics don't particularly link in to anything you'll be doing and are just "for interest's sake". Also, a lot of time is spent on the more intuitive aspects of Model Builder, but little to none is allotted to troubleshooting and the less intuitive aspects (for example, how to incorporate variables throughout a model or other issues with generalising a custom tool built within Model Builder).

If taking the course, be aware that the final submitted assignment requires formulating your own research question and unless you're already working in the field, can necessitate a significant amount of literature review for even the given example research questions. The gap in expectations and assistance is more of a chasm.

Unless you have the better part of a week free to commit to the course, it is advised that you skip ahead to the final assignment immediately and spread it over the full four weeks, spending the first week formulating the question, the second producing the classified raster and the third the model builder model, including any research necessary for this step. This gives the last week to produce products for submission or continue the work from the third week.

Hopefully in upcoming repeat sessions of the course, pacing will be improved, the grading rubric provided before final submission for the sake of transparency and clarity, and a little more guidance and actual feedback available in the forums, which are largely deserted at this point.

This is my personal review regarding this course. I am an Urban Planner by profession with a graduate as well as post graduate degree in Urban Planning. But still I can say that the way coursera teaches me the minor concepts regarding GIS, I didn't got this level of teaching even in my masters degree. The best part of this course was the final assignment as it was a bit different from the earlier assignments. This was more of an open ended assignment in which me as a learner utilized my own brain to do an analysis in my own area of interest. I am really thankful to coursera for helping me out to do the same.

Probably the best course in the specialization. You learn different tools, and at the final, each student designs a personal project.

I really think that this course is the best specialization already available online. I didn't regret to pay for a certificate.

Feedback in the forums was sparse and often required a long wait time to get a response from an AI - if at all. Glitches regarding certain tools made completing particular projects difficult, and solutions were not always implemented to help students navigate these difficulties easily. The specialization is great, but this particular course has been the most frustrating for me.

One of the most challlenge, and encouraged course! The level of working is very hard! The professorr and materal are suitable to have success, on top of that the advices and feedback received by the peers that seriously work on it are priceless and well recognized, frutfully and rich of new ideas to continue the data analisys. Thanks 🙏 UC Davis, Thanks Coursera!

Great course and great instructor! In the fourth course in the GIS specialization, you learn about satellite imagery and how you can use this type of data to test hypotheses. The course will push you to explore more on your own and apply the things you have learned in all four courses. I highly recommend this course!

Great course that helps the learner gain an understanding of remote sensing and the processing that can be done on that type of data. Also a good intro into automation (model builder). The final project helps students prepare for the Capstone.

There's a lot here if you haven't done anything like this before. But if you have the 6 to 10 hours a week to do it (especially on the later stuff) you will certainly understand the basics of ArcMap. Good teaching, good exercises.

I think its a great opportunity to be part of this course especially knowing how to build models. The assignment was also a great way to put our thinking cap on to solve real world problem. Thanks Nick and your team.

This course has really good content, a lot to learn and the final peer review assignment was my favourite in the series. If it was not for this course I would have lost my mind during the COVID lockdown.

So much to learn....this course was great, the focus is not for everyone involved in GIS, but makes you wonder how many things can be improved in your own workflow
