Does the system offer choice of cartography preferably with both vector and raster types? 3. Are the charts supplied with the system up-to-date at the time of sale? 4. Does the manufacturer provide training or have a network of dealers authorised to train on their behalf? 5. Is the User Manual good enough for self training? 6. Does the chart format provide datum shift values? 7. Does your GPS output the datum with positional information? 8. Does the ECS / RCDS manage horizontal geodetic datums?
