Introduction
Cartography is the art and science of creating maps, and it has played a crucial role in human history for millennia. From ancient cave paintings to modern satellite imagery, maps have been used to depict the world around us, helping us to navigate, explore, and understand our environment [1,2]. Over the past few decades, cartography has undergone a significant transformation, driven by advances in technology and data availability. Today, cartographers have access to powerful tools that allow them to create maps that are more accurate, detailed, and informative than ever before [3,4].
The history of cartography can be traced back to ancient civilizations such as Babylon, Greece, and China, where maps were created for military, religious, and navigational purposes [5,6]. However, it was not until the 16th century that cartography began to emerge as a distinct field of study, with the publication of the first modern atlas by Abraham Ortelius. The following centuries saw a rapid expansion in the production of maps, driven by advances in printing technology and the increasing demand for accurate and detailed maps by explorers, navigators, and military strategists [7,8].
The 20th century brought about a revolution in cartography, with the introduction of digital technologies that transformed the way maps are created and used. One of the most significant developments was the advent of Geographic Information Systems (GIS), which allow cartographers to capture, store, analyze, and display spatial data in ways that were previously impossible [9]. With GIS, maps can be created and manipulated with great precision, and diverse data sources can be integrated to create highly informative and visually appealing maps. Remote sensing technologies, such as satellite imagery, also became widely used in cartography, enabling cartographers to create maps that reflect the physical features and environmental characteristics of the earth's surface [10,11].
Another major development in modern cartography is the use of data visualization techniques to create maps that are both informative and aesthetically pleasing [12]. By using advanced visualization tools and techniques, cartographers can create maps that convey complex information in a clear and accessible manner [13]. This has been particularly important in fields such as epidemiology, where maps are used to track the spread of disease and inform public health policies [14].
Finally, the advent of web-based mapping has transformed the way maps are accessed and used by the general public [15]. With the rise of online mapping platforms such as Google Maps and OpenStreetMap, maps have become widely available and accessible to anyone with an internet connection [16]. This has led to the creation of a new generation of cartographers, who use web-based tools and technologies to create maps that are highly interactive and user-friendly [17].
This review paper aims to provide an overview of the latest developments in cartography, with a particular focus on the most commonly employed methods. The paper is organized as follows: first, we will provide a brief historical overview of cartography, highlighting some of the major milestones in the development of the field. Next, we will discuss the impact of digital technologies on cartography, examining the ways in which GIS, remote sensing, and data visualization have revolutionized the field. We will then provide a detailed overview of the most commonly employed methods in modern cartography, including GIS, remote sensing, data visualization, and web-based mapping. For each of these methods, we will examine the advantages and limitations, as well as the applications in various fields, such as urban planning, environmental management, and disaster response.

Focus on advances in cartography techniques
We identified four main techniques that have seen significant advances in cartography over the past few decades: GIS, remote sensing, data visualization, and web-based mapping. Each technique has unique characteristics and capabilities that allow cartographers to create maps and visualizations that can convey complex information in a clear and concise manner. Table 1 provides an overview of the most commonly employed methods in each of these four techniques, along with their applications, advantages, and limitations. We also found that these techniques have been widely applied in various fields, including urban planning, environmental management, and disaster response. For instance, GIS has been used to analyze the spatial distribution of population, land use, and transportation infrastructure to support urban planning and emergency management. Remote sensing has been used to monitor environmental changes such as deforestation, water quality, and land cover changes. Data visualization has been used to present complex data in a simple and understandable manner for decision-making purposes, while web-based mapping has been used to enable interactive and participatory mapping for tourism, navigation, and community engagement.
In addition to these four techniques, we also identified emerging technologies that have the potential to revolutionize the field of cartography, such as artificial intelligence, augmented reality, and virtual reality. These technologies offer new possibilities for creating more interactive, personalized, and immersive maps and visualizations that can enhance communication and decision-making.

In addition, GIS and RS have made it possible to create dynamic maps that can be updated in real-time, providing users with the most current information available.
One specific highlight from our review is the use of machine learning techniques in cartography. Machine learning algorithms have the ability to analyze large datasets and identify patterns and relationships that may not be immediately apparent to humans. This makes it possible to create more accurate and detailed maps that can be customized to meet the specific needs of users. For example, machine learning algorithms can be used to identify patterns in traffic flow, allowing cartographers to create more efficient transportation routes.
In comparing the different methods employed in cartography, we found that machine learning techniques offer several advantages over traditional methods. For example, machine learning algorithms can analyze large datasets much more quickly and accurately than humans, which can lead to significant time savings. In addition, machine learning techniques can be used to identify patterns and relationships that may not be immediately apparent to humans, which can lead to more accurate and detailed maps.
However, it is important to note that machine learning techniques are not without their limitations. One potential limitation is the need for large amounts of high-quality data to train the algorithms. This can be a significant barrier in some cases, particularly in areas where data is scarce or of low quality. In addition, machine learning algorithms can be complex and difficult to understand, which can make it difficult for non-experts to interpret the results.
