Open WKT File

Well-Known Text (WKT) is a text markup language used for representing vector geometry objects on a map, spatial reference systems of geographic coordinates, and spatial datasets. WKT file extensions are primarily associated with 'Well-Known Text' by Open Geospatial Consortium, Inc. and often are used to import and export geographic data.

GeoSpatial Applications

Well-Known Text files are used extensively in geospatial applications. For example, in programs such as QGIS or AutoCAD, you can directly open WKT files to visualize geomappings. In addition, libraries such as GDAL (Geospatial Data Abstraction Library) and PostGIS use WKT format to read and write spatial data.

Programming Libraries

If you are a developer and work with geospatial data, two major programming libraries, GeoPandas for Python and sf for R, allow you to interact with WKT files. You can read, filter, visualize, and even write WKT files with these libraries.

Databases

WKT files are aplenty in spatial databases like PostgreSQL equipped with PostGIS extension or SQL Server. Utilizing their spatial functions, we can store, retrieve and analyze geospatial data within relational database management systems.

WKT File Important Information

While working with WKT files remember few important things. They are human-readable hence easy to interpret. They are extremely versatile in storing geospatial data in databases, GIS applications, and programming languages. However, they might not be the best at preserving complex geographic features and the amount of data they can handle might be limited.
