How to Use Map

Project Information

Project name Site / location

UnitsDatum

Coordinate reference system

Select the project CRS explicitly. If your survey controller is set to Minna datum with UTM, choose the matching Minna / UTM zone. The selected zone or Nigerian Grid belt will not change automatically.

Point ToolsCreate / derive

Choose a tool to select existing points and create a derived survey point without leaving the map.

Best available phone GPS fix. Accuracy depends on the device and sky visibility; verify against known survey control.

Plot Area / Traverse

For a closed parcel, keep survey points in boundary order and select Closed traverse. The closing leg is calculated automatically; a repeated first point is ignored in the computation.

Add at least two valid survey points to calculate traverse results.

Adjustment

Choose an adjustment method and preview it. Raw coordinates remain untouched until you apply an adjustment.

Coordinate TransformationPreview before apply

Source CRSTarget CRSDatum / Helmert method

Transform the whole point set at once. Control residuals can be checked when target control coordinates are supplied in the Point Manager.

Import / Export
