Hello, World! This is Yanfu’s portfolio 🎉 🎊 🎈

Summary 😎 (This is generated from the ChatGPT after I showed it this page! 😂)

• LinkedIn.

Here are the key words on this page! 🔑

My interactive live demos……👀

My interactive live demos are hosted on my personal device for development and testing. Because the system is not running 24/7, please use the Send Inquiry link to let me know when you plan to view the demos.

*Please be ware that the self-signed certificate will trigger security warnings in browsers when you visit my site, and there is a way to bypass that warnings documented in here:

How to temporarily bypass (Chrome, Edge, Firefox) warnings

• Google Chrome/Microsoft Edge: On the warning page, click the Advanced button, then scroll down and click the “Proceed to [website address](unsafe)” or “Continue to” link. A quick trick in Chrome is to simply type thisisunsafe anywhere on the error page.
• Mozilla Firefox: Click the Advanced button, then click Accept the Risk and Continue.

Access to my interactive live demos requires login credentials. I will provide the login details in my response email. The demos available for viewing are listed below.

• Georeferencing UAV Orthos (Saving cost for your expensive ($$$) image stitching process)
• Online Viewshed Analysis (ESRI charges this functionality in their Spatial/3D Analyst extensions for ~$650/yr for enterprise users)
• The ArcGIS Server Feature Service (Published the service on an ArcGIS Server for Linux running as a container, no need for a separate license for ArcGIS Server on Kubernetes, which priced ~$50,000/yr for 64 vCPUs)

For future road map, in the next few years……

• Changing all my existing demonstrations to use secured TCP protocol (HTTPS).
• Get a trusted certificate from Let’s encrypt (by doing this, security warnings in browsers will be gone).
• Purchase a used bare-metal server and host my demos on it so they can run 24/7. This would actually be cheaper than renting an R5.4xlarge EC2 instance on AWS.

My static pre-recorded demos……👀
