Coordinate Reference Systems (CRS)
Coordinate Reference Systems (CRS) are fundamental in spatial data, providing a framework for locating and mapping geographical features on the Earth's surface. These systems use coordinates to pinpoint locations with precision. Commonly employed for mapping and navigation, CRS enables seamless integration of diverse spatial datasets.
The two primary types are:
Geographic CRS, utilizing latitude and longitude
Projected CRS, employing Cartesian coordinates for accuracy in specific regions.
Standardization, such as the widely used WGS84, facilitates global data interoperability. Understanding CRS is crucial in geospatial analysis, ensuring accurate spatial representation and meaningful interpretation of data in many fields including off-shore / marine datasets.
CRS Authorities
CRS authorities play a pivotal role in defining and maintaining Coordinate Reference Systems (CRS). These organizations establish standards for spatial data, ensuring consistency and interoperability across applications. Examples include the European Petroleum Survey Group (EPSG) and the Open Geospatial Consortium (OGC), contributing to global spatial data infrastructure.
Well-Known Text (WKT) provides a standardized language to represent Coordinate Reference Systems (CRS). It's a concise method for clear communication of spatial data, crucial in various geospatial applications and data exchange.
What is supported by the Platform?
Currently the application recognizes all spatial datasets that contain a CRS code based on the EPSG standard. Once processed, all spatial data is visualized using a web optimized Web Mercator projection. Cursor locations are displayed as either WGS84 coordinates or Universal Transverse Mercator (UTM) CRS.
