Mô tả

"This is a great and advanced web mapping application course to solve real world problem. It's very to follow up and the instructor is very knowledgeable. I would recommend it to anyone who is interested in the field webmapping. Thanks Michael."

"Very nice course on using leaflet to build web maps. Many aspects of leaflet and leaflet plugins are covered along with some more advanced analysis using turf. The code examples are helpful in getting started with leaflet maps and adding widgets for interacting with the map."

This course will provide you with the knowledge you need to 

  • create a Leaflet web map
  • add map controls 
  • choose from a variety of background maps
  • add your own GIS to it
  • style your data
  • find specific data
  • analyze spatial relationships 

At the end of the course you will be able to create web interfaces to view, search, and analyze your GIS data and make them accessible to anyone with a web interface for free!

This course requires only a text editor and an open source web server to get started designing web GIS applications.

Yêu cầu

  • This course has a prerequisite called Introduction to Web Programming for GIS Applications. I assume that students will be familiar with the subject matter of that course up to at least Lesson 61.
  • If you have some familiarity withHTML, CSS, jQuery, Bootstrap, JavaScript, and GIS you should be able to take this course without the prerequisite but I am basing this course on that level of knowledge.
