Thematic Layering in GIS

Thematic Layering in GIS

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)...

Selected Data About Geographic Locations

Selected Data About Geographic Locations

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...

Applications of GIS: Disaster Management and Emergency Response

Applications of GIS: Disaster Management and Emergency Response

Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Levels of Use of a GIS

Levels of Use of a GIS

Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...

Area of Science:

Ecology
Geoinformatics
Environmental Science

Background:

Ecological research relies on spatial databases, but data in Switzerland are fragmented across institutions.
Inconsistent formats and scattered data necessitate extensive data management and geomatic operations for joint use.

Purpose of the Study:

To introduce SWECO25, a unified Swiss-wide raster database designed to streamline ecological research.
To provide standardized, high-resolution environmental data for Switzerland.

Main Methods:

Compiled 5,265 layers across 10 environmental categories (geologic, topographic, bioclimatic, etc.).
Standardized all layers to a common 25-meter resolution grid with consistent extent and coordinate system.
Included standardized source data and newly calculated layers (e.g., focal/distance statistics).
Validated data integrity and confirmed negligible impact of standardization on values.

Main Results:

Developed SWECO25, a comprehensive Swiss spatial database at 25-meter resolution.
Successfully standardized diverse environmental data layers into a unified format.
Validated the integrity and accuracy of the standardized dataset.

Conclusions:

SWECO25 significantly enhances accessibility and usability of Swiss environmental data for ecological research.
The database is available on Zenodo and planned for regular updates and expansion.
