I'm in the market to purchase a GPS for tracking and visualizing data. I understand that most GPS maintain a tracklog file that contains lat long and other data that can be downloaded to a PC. Through the use of third party software this data can then be plotted to show points and/or lines of travel. Is each record in the tracklog a point (or node) that then requires software to interpolate the 'arcs' in between?
I would like to be able to create my own geographic trackfiles (probably in shapefile or geodb format) and I would like them to be polylines (or arcs) rather than a series of points. MxGPS looks like it converts tracklog data to shapefiles, but it's unclear (from the website) whether it creates a polyline shapefile or a point shapefile.
I'm a GIS Cartographer by profession, so I'm comfortable with the GIS technology, but fuzzy on the GPS side of things and learning.
Thanks in advance for any input you may have.
