- For PDFs with printed point labels, the app says it matches those labels to the coordinate file and checks the plot fit.
Field notes
The interface accommodates both coordinate files and plot drawings, with several column-order options and pasted-point input. It describes automatic matching for PDF plots with printed point labels, while unlabeled plots can be aligned with manually entered control points. GPS setup includes choosing or detecting a coordinate system and recording two to four known points for calibration; the page also notes that some in-app browsers block file selection.
