GIS & Geospatial Analysis with Python, Geopandas, and Folium

Udemy Instructor

Welcome to GIS & Geospatial Analysis with Python, Geopandas, and Folium course. This is a comprehensive project-based course where you will learn step-by-step on how to perform geospatial analysis techniques specifically leveraging GIS for urban planning. You will build projects like mapping population density, monitoring air quality, mapping flood risks, mapping snow cover, modeling and optimizing routes, and we will be using Python libraries like Pandas, Geopandas, Folium, Geocoder, and Ipyleaflet. The course perfectly combines geospatial analysis with urban planning, providing an ideal opportunity to practice your programming skills while improving your geospatial knowledge. In the introduction session, you will learn the basic fundamentals of geospatial analysis, such as getting to know its use cases, understanding geospatial analysis workflow, learning about technical challenges and limitations in GIS. Then, in the next section, we will learn about geospatial data visualization methods like choropleth maps, heatmaps, 3D maps, flow maps, point maps, and cartogram maps. This section is very critical because it provides you with the necessary tools to communicate your analysis effectively to stakeholders and decision-makers involved in urban planning. Afterward, in the next section, we will download geospatial datasets from Kaggle, the datasets contain valuable information like demographic data, land use data, and climate data. Before starting the project, we will learn about basic geospatial techniques, like importing geospatial data, displaying interactive maps, extracting coordinates from map, calculating distance between two locations, finding nearby cities using proximity analysis, performing geocoding and reverse geocoding. This section is very essential because it provides you with the fundamental skills and knowledge needed to effectively work with geospatial data and prepare you well for the upcoming projects. In the next section, we will start the projects. There will be five projects. In the first project, you will analyze population density to identify densely populated areas and assess their suitability for urban planning initiatives. For the second project, you will focus on monitoring air quality to identify areas with high pollution levels and assess their impact on public health and the environment. In the third project, you will map flood risk areas to facilitate disaster preparedness and mitigation efforts. In the fourth project, you will map snow cover to support transportation planning and finding safer travel routes during winter season. Lastly, in the fifth project, you will develop optimal transportation routes to improve efficiency and reduce travel times for urban commuters.First of all, before getting into the course, we need to ask ourselves this question: why should we learn about geographic information systems and geospatial analysis? Well, here is my answer: geographic information systems are essential for understanding spatial relationships and patterns in data, enabling us to make informed decisions and solve real-world problems more effectively. These technologies play a crucial role in various industries, for example, urban planning, environmental science, and public health, allowing us to analyze spatial data and derive meaningful insights for better decision-making. Additionally, there are tons of business opportunities, for example, you can develop custom GIS applications like property valuation tools, supply chain optimization platforms, or tourism route planners. These applications leverage location-based insights to drive decision-making and enhance operational efficiency.Below are things that you can expect to learn from this course:Learn the basic fundamentals of geospatial analysis and its use casesLearn geospatial analysis workflow.

Claude Agentic AI in Practice Certification Course

Udemy Instructor

This course contains the use of artificial intelligence.Build intelligent, autonomous, and enterprise-ready AI systems with Claude Agentic AI in this comprehensive 12-week, hands-on course. Designed for developers, AI engineers, architects, technical leaders, and professionals exploring the future of automation, this course teaches you how to design, build, evaluate, and deploy real-world agentic AI systems using Claude.Unlike traditional generative AI applications that only respond to prompts, agentic systems can plan tasks, use tools, retrieve information, maintain memory, collaborate with other agents, and take actions toward defined goals. Throughout this course, you will move beyond basic chatbot development and learn how to create practical AI agents, multi-agent systems, and intelligent enterprise workflows.You will begin by exploring the foundations of Agentic AI vs Generative AI, the Claude ecosystem, Claude models, APIs, tool use, and common agent design patterns. You will then develop advanced skills in Claude prompt engineering, including system prompts, behavioral shaping, structured prompting, XML and JSON output schemas, prompt evaluation, and iterative improvement techniques.A major focus of the course is tool use and function calling with Claude. You will learn how to create reliable tool schemas, connect agents to calculators, databases, retrieval systems, business APIs, and external services, and build robust tool invocation workflows with validation, error handling, and retries.The course also covers Retrieval-Augmented Generation, commonly known as RAG, including document chunking, embeddings, vector databases, retrieval pipelines, and methods for evaluating retrieval quality. You will combine Claude with enterprise knowledge sources to build accurate, context-aware assistants and internal knowledge agents.As your systems become more advanced, you will implement AI agent memory, session state, persistent storage, vector memory, and symbolic memory. You will design single-agent systems using planning, task decomposition, reasoning loops, observability, logging, and recovery mechanisms.You will then progress into multi-agent architecture, exploring supervisor-worker models, specialized agent roles, swarm patterns, agent communication, conflict resolution, and coordination strategies. You will compare popular AI orchestration frameworks, including LangChain, LlamaIndex, and custom workflow approaches, while learning when to use deterministic workflows versus autonomous agents.Real-world enterprise applications are integrated throughout the course. You will explore AI copilots, customer support automation, internal knowledge assistants, software engineering agents, and intelligent business workflow automation.Security and governance are also central to the curriculum. You will learn about AI governance, prompt injection, sensitive data leakage, access control, guardrails, auditing, compliance, and enterprise risk management.Finally, you will learn how to deploy and scale Claude-powered agents using APIs, serverless architectures, containers, monitoring, cost optimization, and human-in-the-loop controls. The course concludes with a capstone project in which you will design, build, test, evaluate, and present a complete enterprise agentic AI solution.By the end of this course, you will have the practical skills and architectural knowledge needed to build reliable, secure, scalable, and production-ready Claude AI agents for real-world applications.
