Exporting GNSS data to GIS without losing its meaning
A clean coordinate export must preserve references, units, identifiers and feature attributes.
Check the reference rules of the export format
CSV exports depend on an agreed coordinate definition and column order. Standard GeoJSON under RFC 7946 uses WGS 84 longitude and latitude in decimal degrees. Reproject projected survey coordinates before exporting them as standard GeoJSON; merely assigning a CRS label does not transform the coordinates.

Test the transfer with a known point
Inspect axis order, units, height type, identifiers and feature descriptions after import. Compare a known coordinate and review attribute encoding, especially across languages. Keep the original observations and a reference note so any transformation or export error can be investigated without repeating the entire survey.

Practical checklist
- Confirm the target format coordinate conventions.
- Verify a known point after importing into GIS.
- Preserve identifiers, attributes and reference documentation.
Plan your GNSS setup
Compare the EQ10 and EQ20 receiver specifications, then discuss the configuration and support your project needs.
