Summary
Urban planning must assess natural disaster risks like flooding and landslides before establishing new settlements. This study found only 6.72% of Alanya is suitable for development due to these risks.
Area of Science:
- Urban planning and disaster risk assessment
- Environmental science and geography
- Sustainable development
Background:
- Rapid urbanization worldwide necessitates new settlement areas.
- Inadequate scientific assessment of natural disaster risks during settlement planning leads to significant life and property loss.
- Identifying high-risk zones is crucial for mitigating disaster impacts.
Purpose of the Study:
- To identify suitable settlement areas in Alanya, Turkey, considering natural disaster risks and biocomfort.
- To analyze flood, landslide, and forest fire risks in the region.
- To assess the suitability of land for new settlements based on multiple environmental criteria.
Main Methods:
- Geographic Information Systems (GIS) analysis.
- Risk assessment for floods, landslides, and forest fires.
- Bioclimatic comfort zone analysis.
- Multi-criteria decision-making for land suitability.
Main Results:
- Flooding was identified as the primary natural disaster risk across a significant portion of Alanya.
- Only 6.72% of the study area met all suitability criteria for settlement.
- The study highlights the limited availability of safe land for development in the region.
Conclusions:
- Integrating natural disaster risk assessment into urbanization planning is essential for safety and sustainability.
- Alanya faces significant constraints for new settlement due to widespread flood and landslide risks.
- Future urban development must prioritize risk-informed land-use planning to minimize potential losses.

52
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

94
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

01:25Selected Data About Geographic Locations
58
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

In the past, planning projects such as schools or public facilities required extensive manual effort to gather and compile data. Information such as property boundaries, soil characteristics, road networks, zoning regulations, and flood zones had to be sourced individually from courthouses, utility providers, and registry offices. Assembling these datasets into a coherent format often took several months, delaying project timelines.The introduction of Geographic Information Systems (GIS)...

Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...
