Publication number: 20030182052Abstract: An Integrated Routing/Mapping Information System (IRMIS) links desktop personal computer cartographic applications to one or more handheld organizer, personal digital assistant (PDA) or “palmtop” devices. Such devices may be optionally equipped with, or connected to, portable Global Positioning System (GPS) or equivalent position sensing device. Desktop application facilitates user selection of areas, starts, stops, destinations, maps and/or point and/or route information. It optionally includes supplemental online information, preferably for transfer to the PDA or equivalent device. Users' options include route information, area, and route maps. Maps and related route information are configured with differential detail and levels of magnitude. Used in the field, in conjunction with GPS receiver, the PDA device is configured to display directions, text and map formats, the user's current position, heading, speed, elevation, and so forth.Type: ApplicationFiled: October 30, 2001Publication date: September 25, 2003Inventors: David M. DeLorme, Keith A. Gray, Gordon Autry, Keith A. Moulton

Patent number: 5948040Abstract: Computerized travel reservation information and planning system that generates "map ticket" output in various media, for guidance and transactions en route. Such print or electronic documents can include bar or alphanumeric codes for automated recognition and/or access. WHERE?, WHO/WHAT?, WHEN? and HOW? menus enable flexible user inquiries accessing selectable geographic, topical, temporal and transactional data records and relational processing. Sub-menus provide further capabilities: e.g. routing, topical searching; searches of events calendars, almanacs, appointment books, related itinerary scheduling; trip budgeting issues, plus travel arrangement availabilities or other goods/services offers. Online communications links access updated or supplemental information on places, times, topics and other provider goods/service offers.Type: GrantFiled: February 6, 1997Date of Patent: September 7, 1999Assignee: DeLorme Publishing Co.Inventors: David M. DeLorme, Keith A. Gray, T. Angus Ferguson

Patent number: 5848373Abstract: A computer aided map location system (CAMLS) provides correlation and coordination of spatially related data between a computer (PDA/PC/EC) and a set of printed maps typically printed on paper depicting surface features at desired levels of detail. A first set of constant scale printed maps substantially coincides with or is overprinted with equal area grid quadrangles of a first scale grid. The first scale grid quadrangles are identified by a first set of unique names. The PDA/PC/EC has a computer display or other computer output, a first database, and display subsystem. The first database includes the first set of unique names of the grid quadrangles of the first scale grid. The boundary lines of the respective first scale grid quadrangles are identified in the first database by latitude and longitude location. The display subsystem causes the display of a selected grid quadrangle or gridname on the PDA/PC/EC display in response to a user query.Type: GrantFiled: July 18, 1997Date of Patent: December 8, 1998Assignee: DeLorme Publishing CompanyInventors: David M.

Patent number: 5802492Abstract: A Computer Aided Routing and Positioning System (CARPS) determines a route along selected waypoints that include a travel origin and a travel destination and intermediate waypoints therebetween. The selected waypoints may be uploaded to or downloaded from various geocoding devices that utilize the Global Positioning System (GPS). A CARPS database incorporates travel information selected from a range of multimedia sources about the transportation routes, waypoints, and geographically locatable points of interest (POIs) selected by the user along the travel route. The CARPS software permits user selection of specified POI types within a user-defined region of interest and user selection of particular POIs from the selected types within the region of interest. The transportation routes, waypoints, POIs and region of interest are identifiable in the computer by coordinate locations of a selected geographical coordinate system.Type: GrantFiled: June 11, 1996Date of Patent: September 1, 1998Assignee: DeLorme Publishing Company, Inc.Inventors: David M.

Patent number: 5559707Abstract: A computer aided routing system (CARS) determines a travel route between a user selected travel origin and travel destination following user selected waypoints along the way. A CARS database incorporates travel information selected from a range of multimedia sources about the transportation routes, waypoints, and geographically locatable points of interest (POIs) selected by the user along the travel route. The CARS software permits user selection of specified POI types within a user defined region of interest and user selection of particular POIs from the selected types within the region of interest. The transportation routes, waypoints, POIs and region of interest are identified in the computer by coordinate locations of a selected geographical coordinate system. The CARS software is constructed to present a user customized travelog for preview on the computer display of the user defined travel route.Type: GrantFiled: January 31, 1995Date of Patent: September 24, 1996Assignee: DeLorme Publishing CompanyInventors: David M.
