What is meant by Geodata import?
The term "geodata import" refers to the process of reading and integrating geographic data into a Geographic Information System (GIS) or other spatial data processing software. It involves incorporating data from various sources and formats into the system to make it usable for further analysis, visualization, or editing.
Typical software functions in the area of "Geodata Import":
- Format Support: Reading various geodata formats such as Shapefiles, GeoJSON, KML, or CSV.
- Coordinate System Conversion: Automatic transformation between different geographic coordinate systems.
- Data Cleaning: Detection and correction of errors or inconsistencies in the imported data.
- Attribute Mapping: Mapping of attributes from source data to target fields in the GIS.
- Data Fusion: Merging data from different sources based on spatial or attributive criteria.
- Validation: Checking the imported data for completeness and consistency.
- Batch Import: Ability to import multiple files or datasets simultaneously.
- Metadata Extraction: Automatic reading and storing of meta-information from source data.
- Preview Function: Visualization of data to be imported before the actual import.
- Logging: Detailed recording of the import process for audit purposes.
Examples of "Geodata Import":
- Importing OpenStreetMap data into a municipal GIS for urban planning.
- Reading GPS tracks from fitness apps into mapping software.
- Importing satellite imagery into a remote sensing system for land use analysis.
- Incorporating geological borehole data into a 3D subsurface model.
- Importing address data for geomarketing analyses in a business intelligence software.
- Reading weather data from various measuring stations into a climate modeling system.
