يمكنك الحصول على خريطة الكثافة السكانية بعدة طرق، حسب ما تريد بالضبط (صورة فقط، أو بيانات GIS قابلة للتحليل).
إذا كنت تريد صورة خريطة جاهزة

🔹 1. خرائط من جوجل أو Our World in Data

موقع: https://ourworldindata.org/grapher/population-density
يحتوي على خريطة تفاعلية يمكنك حفظها كصورة.

يمكنك التكبير على بلدك (مثل مصر) ثم الضغط بزر الماوس الأيمن وحفظ الصورة.

2. خريطة من الأمم المتحدة أو البنك الدولي

UN Population Division: https://population.un.org

World Bank DataMap: https://datatopics.worldbank.org/world-development-indicators

📊 ثانياً: إذا كنت تريد بيانات GIS (Shapefile / GeoTIFF)

🔹 1. من موقع WorldPop (الأشهر عالميًا)

رابط مباشر: https://www.worldpop.org

اختر الدولة (مثلاً Egypt)، ثم اختر "Population Density (persons per hectare)"

يمكنك تحميل البيانات بدقة 100م أو 1كم بصيغة GeoTIFF (يمكن فتحها في QGIS أو ArcGIS).

🔹 2. من موقع GHSL التابع للمفوضية الأوروبية

رابط: https://ghsl.jrc.ec.europa.eu

اختر GHS-POP أو GHS-SMOD (بيانات الكثافة الحضرية)

هذه خرائط عالمية بدقة 250م تشمل الكثافة السكانية لكل العالم.

🔹 3. من موقع NASA Socioeconomic Data and Applications Center (SEDAC)

رابط: https://sedac.ciesin.columbia.edu

ابحث عن Gridded Population of the World (GPWv4)
يمكنك تحميل البيانات حسب البلد أو العالم كله.

👽.Google AlphaEarth Foundations – A New Step in Earth Observation:

• Google DeepMind has introduced AlphaEarth Foundations, a new AI-based model that helps us understand our planet in smarter and faster ways.

• It works like a virtual satellite, combining data from satellite images, radar, LiDAR, 3D maps, and climate models into one intelligent global system.

◇.How It Works:

•The Earth is divided into 10×10 meter cells.

•Each cell gets a 64-number vector (embedding) that describes what’s on that land — vegetation, water, urban area, etc.

•Uses 16× less storage than older systems.

•Provides yearly global data (2017–2024) for change detection and analysis.

◇.Why It’s Important for GIS & Remote Sensing:

•High-resolution 10 m data from multiple sources.

•Useful for land-cover mapping, urban growth, vegetation change, and more.

•Available on Google Earth Engine as “Satellite Embedding V1”.

•Saves time — no need to process raw satellite data manually.

•Can be used with AI or ML models for better predictions and analysis.

◇.Applications:

• Track deforestation or vegetation growth.

• Monitor urban expansion.

• Support climate and environmental research.

• Help in site selection and land-use planning.

◇.How to Explore:

• Go to Google Earth Engine, search for “Satellite Embedding V1”, and start experimenting with this powerful dataset.

• AlphaEarth Foundations shows how AI and GIS are coming together to give us a clearer, smarter view of our planet.
