This channel is dedicated to helping you kick-start and master Geographic Information Systems (GIS) tasks. I always try to make the demo simple and easy to reproduce the analysis. I offer tutorials, tips, and step-by-step guides to help you perform both basic and complex GIS tasks using a wide range of GIS tools, including:
QGIS
ArcGIS
Google Earth Engine
PostgreSQL
PostGIS
Python
JavaScript
R

Publish your portfolio online without any programming experience
Ready to share your work with the world? In this step-by-step guide, I'll show you how to take your HTML portfolio and deploy it online using GitHub Pages-all for FREE!
What You'll Learn in This Video:
✅ Common mistakes to avoid, when editing an HTML, javascript or CSS code.
✅ The exact settings to enable GitHub Pages deployment.
✅ How to upload your index.html to a GitHub repository.
✅ How to customize your site for a polished, professional look.
Key Things to Watch Out For:
File Structure 🗂️
Ensure your index.html is in the root folder of your repository.
Example:
✅ Correct: index.html at the top level of your repository.
❌ Incorrect: index.html buried inside a folder like mywebsite/index.html.
Branch Selection
In the GitHub Pages settings, select the branch where your files are stored.
If your portfolio is on the main branch, make sure you choose main.
Wait for Deployment
GitHub takes 1-2 minutes to deploy your site. Be patient! Refresh the GitHub Pages URL once it's ready.
Customizing the Look
Update your title tag to personalize the page.
Example: Change "Massively by HTML5 UP" to "My Portfolio - [Your Name]".
Replace default text and images in sections like headings and articles to reflect your projects.
Test Your Site
Open your new URL (e.g., yourusername.github.io/) to make sure it looks right.
Fix any broken links or missing images.

Clip Raster or Extract by Mask? | Know the difference
มุมมอง 2914 วันที่ผ่านมา
Do you use "Clip" or "Extract by mask"? There isn't so much diff in their outputs, BUT you will alter the data structure with one of these choices...... Know the difference ⤵️ 𝐂𝐥𝐢𝐩 𝐑𝐚𝐬𝐭𝐞𝐫 1. When you use the Clip Raster tool, you will notice that it aligns the output to the smallest bounding box around the geometry. This ignores the original grid structure. 2. If your geometry does not align pe...

This day is all about prompt engineering. Use AI tools like DALL-E, MidJourney, Stable Diffusion, or ChatGPT with geospatial capabilities to create a map based on AI-generated content. The challenge is to get the right prompt and critically assess the output-how well does AI capture or distort the map's intent? Source: github.com/desmond-lartey/MapChallenge/tree/Fires/2024

please help me how to fix this error QGIS background task for loading assets was terminated. in STAC API browser
@@tinsu.a1658 could you maybe share the error message or a screenshot?.....sometimes if you try to stream or download very large area, then it doesn't work fine.
Uff..I thought I don't know how to use this plugin. This tool doesn't work well. It should be more simple - click on the water or road and the AI should generate a shape. Today you have to control, any steps the drawing - it's works slower than a human draws. Not to mention the fact that it should maintain standards and spatial conditions. I have yet to find an AI product worth recommending in QGIS. Anyway, thanks for the video.
Maybe you can share the code to ease deploying… thank you
Hello, yes, i have shared the code in the description and also in the comment here. Check again github.com/desmond-lartey/Media/blob/Fires/Symbology_Popdensity.py
Hello. I have a question. When I register, don't I lose access to my codes? Thanks for your explanation!
hello, no you wont loose your code. You can also change the project to a new cloud project you have registered. Assets and everything will be there
@@desmondlartey31 Thanks a lot, Desmond. Best wishes from Brazil.
Good work done Snr. Please do you mind sharing the engine code?
Thankyou Desmond Lartey
You are doing a great job man. I appreciate your hard work and efforts. But as a viewer here's what I faced: your voice is low and due to it background music is interfering and also subtitles are turned off by you; for whatever reasons (because subtitle sometime helps in understanding some words that are limited by accent to us).
thanks for the feedback. I will try to always turn the subtitles on.
How are we supposed to hear you if you keep the music volume that high? Thumbs down because this tutorial is totally useless, scrap this crap.
Sir your videos and linked posts are very informative. I learn GIS related lot of things from your linkedin posts. can you please make a playlist for complete GEE. Love from India😍😍
thanks for the support
Great work! Can I get the code?
