Global and Local GIS: From Worldwide Projects to Urban Solutions
Geographic Information Systems (GIS) play a crucial role today in solving a wide range of tasks – from global climate studies to local urban solutions. GIS enables the integration of geographic data with analytical tools, helping make informed decisions in fields such as urban planning, environmental monitoring, and infrastructure development. In this article, we will explore how GIS is used globally and locally, the problems it helps solve, and the future prospects of its application.

What Are Global and Local GIS?
Both global and local GIS are based on computer systems that collect, analyze, and visualize geographic information. However, their areas of application can differ significantly.
Global GIS
Global GIS covers large areas, including the entire planet or major regions. These systems are often used to monitor global changes, such as climate change, deforestation, glacier melting, and disaster forecasting.
Local GIS
Local GIS is used to solve more specific tasks at the level of cities, villages, or individual areas. These systems manage infrastructure, develop urban plans, monitor traffic flows, and control air quality.
Global GIS: Monitoring Planetary Processes
Global GIS can combine vast amounts of data from various sources, such as satellite images and ground measurements. This allows for monitoring and analysis of global changes on Earth.
Monitoring Climate Change
One of the key tasks of global GIS is monitoring climate change. These systems track how the planet's temperature, sea levels, and ice caps evolve. Global GIS also helps predict the consequences of climate change, allowing governments to better prepare for potential disasters.
Disaster Forecasting
Global GIS is used to predict natural disasters such as earthquakes, tsunamis, and hurricanes. By analyzing satellite data and ground measurements, it is possible to forecast where disasters may occur and prepare populations for evacuation.
Deforestation and Biodiversity Protection
Global GIS helps monitor the scale of deforestation and assess the impact of human activities on biodiversity. This allows for the development of more effective strategies for protecting vulnerable ecosystems.
Local GIS: Urban Planning Solutions
Local GIS focuses on specific areas, usually cities or regions. These systems help cities develop more rationally, optimizing transportation systems, resource management, and infrastructure.
Urban Planning and Infrastructure
Local GIS allows cities to develop infrastructure plans. With these systems, authorities can assess where to place new buildings, roads, bridges, and other objects. They also help plan green areas and parks, creating ecologically balanced urban spaces.
Transportation and Logistics
Local GIS can analyze traffic flows and optimize movement within cities. This helps develop effective public transport routes, plan new roads, and resolve congestion issues.
Air Quality Monitoring
An essential function of local GIS is environmental monitoring in cities. These systems track air and water quality, allowing for timely responses to environmental problems and the development of measures to address them.
Challenges and Prospects for GIS
Despite the many benefits, there are certain challenges faced by GIS developers and users. One of the major challenges is the collection and processing of vast amounts of data, which requires significant computing resources. However, with the advancement of cloud technologies and computing power, these issues are becoming less critical.
Integration with the Internet of Things (IoT)
One of the promising directions for GIS development is integration with the Internet of Things (IoT). This will allow even more data to be gathered from sensors installed worldwide, facilitating more accurate analysis and predictions of environmental changes.
Automation and Artificial Intelligence
Artificial intelligence (AI) and machine learning can significantly enhance GIS efficiency, enabling automated data processing and the creation of models that can predict changes in both natural and urban environments.
Global and local GIS are indispensable tools for solving both global environmental issues and local urban challenges. They provide detailed analysis, allowing informed decisions in many areas.
