gis - GPS application with downloadable Maps -

-

i looking map application following:

  • windows based.
  • city/town street maps downloaded computer (i.e. not required wireless internet connection map images real-time).
  • uses gps on computer via comport.
  • allows me visually track on map drive around.

we have written our own gps application uses esri shapefiles. periodically complaints customers saying gps "delayed" (i.e. icon showing current location 2-3 blocks behind true location).

to isolate whether might hardware related or our software, test alternative applications see if have same delay.

i used microsoft streets , trips on couple of road trips. mid-level package comes gps receiver.
