We are running parallel transect lines for a survey, which will roughly cover a rectangular area. When making the transects, we will periodically capture spatial locations of features and events we encounter.
Due to technical issues, we can only record the latitude/longitude coordinates of the very beginning of the first transect (i.e. one corner of the rectangle). The locations of all our logging of other features/events will be recorded relative to the origin, with x y coordinates (running along the east-west north-south axes, respectively).
I would like to georeference all our data points from the survey into a map, where I can click on any data point and get its coordinates in latitude and longitude.
How should I do this?
I prefer a solution that could be done in QGIS 1.7+, but ArcGIS 10 is OK, too. Thanks!
