Short instructions for preparing clean survey files and producing reliable Google Earth outputs.
How to convert CSV coordinates to KML
- Keep one header row and save the file as UTF-8 CSV.
- Include asset name or ID, latitude and longitude columns.
- Open CSV to KML, select the file and confirm the detected fields.
- Generate the KML and inspect it in Google Earth.
Latitude and longitude must use decimal degrees. For example, Lahore is approximately latitude 31.52 and longitude 74.35.
How node-to-node feeder processing works
The tool reads connected LineString sections, starts from the selected feeder source and traverses downstream connections. At branches it processes the shorter branch first, returns to the branch point and continues with the remaining route. This avoids recursive browser calls and supports large feeders without a maximum call-stack failure.
Before comparing WebGIS and MIS records
- Export WebGIS pole and equipment data in CSV format.
- Keep equipment identifiers consistent across systems.
- Choose the correct UTM zone for projected coordinates.
- Review the result before updating an operational database.
