Abstract

A handheld graphic user interface (GUI) personal digital assistant (PDA) computer is coupled to a GPS/dGPS receiver module which is also compact in size to provide for the collection of data associated with position information. Additional features provided by the stored program in the PDA include a nested set of menus for pre-organizing data collection, navigational functions to permit a user to navigate to a desired location with audio and visual feedback, mapping capability, overlay generation functions which further organize and display the collective data, etc. A full host of functionality provided by a geographical information system (GIS) software package are not provided due to the limited processor performance capability and memory space but only data collection data and mapping display and generation capabilities as selected for implementation of the desired functions.

Claims

1. A handheld, geographical data collection device, said device comprising a computer with a graphic user interface to facilitate data entry by a user, a stored program having means for selectively displaying a format of nested forms for user entry of collected data, means for displaying at least one of a plurality of maps on said interface, and a GPS and a dGPS receiver coupled to said computer to provide real time GPS position data to said computer for display on said map and entry as data.

2. The device of claim 1 wherein said stored program includes means for user selection of an overlay for display on said interface, said overlay being specific to a particular class of data and having a particular associated set of menus dedicated to the class of data being collected.

3. The device of claim 2 wherein said stored program provides a plurality of overlays for user selection.

4. The device of claim 3 wherein said stored program has means for a user to display more than one overlay, said overlays being transparent, and wherein a user has access to only an uppermost overlay'"'"'s associated set of menus.

5. The device of claim 4 wherein said stored program has means for display of said overlays over one of said maps.

6. The device of claim 5 wherein said stored program has means for said user to select an arbitrary portion of a map for display on said interface.

7. The device of claim 6 wherein said stored program has means for determining a plurality of map elements for display in that portion arbitrarily selected by determining the vectors of each map element contained in said map and choosing for display only those whose vectors intersect or lie within said selected arbitrary portion.

8. The device of claim 7 wherein said stored program has means for a user to designate a desired destination, and means for progressively indicating advance towards said desired location.

9. A handheld portable computer for gathering substantially all material data related to the agricultural operation of a farm through an entire growing season, said portable computer having a graphic user interface to facilitate the entry of said data into said computer, a memory for storing said data, a GPS and a dGPS receiver coupled to said computer to provide real time GPS position data to said computer for display on said interface, and a stored program to provide the organized visual display of said data in a variety of formats.

10. The portable computer of claim 9 further comprising means for synchronizing the data stored in said portable computer with the data stored in a second computer with a small number of fixed commands.

11. The portable computer of claim 10 further comprising means for synchronizing the data stored in said portable computer with the data stored in a second computer upon connection therebetween with said electronic connection means.

12. The portable computer of claim 11 wherein said stored program includes means for displaying a plurality of nested shell displays on a screen, at least some of said displays including a plurality of data storage lines and a scrollable list from which an appropriate data entry may be selected for entry and display in one of said data storage lines.

13. The portable computer of claim 12 further comprising means for populating said scrollable lists solely with entries which are properly selectable in response to the data already stored in said portable computer.

14. The portable computer of claim 13 further comprising means for connection to a second data base, said second data base having means for storing a significantly greater amount of data than may be stored in said portable computer memory.

15. The mobile computer of claim 14 further comprising means for selectively accessing said second data base on operator command to thereby provide additional explanatory data related to any data contained in said stored program.

16. The portable computer of claim 15 wherein said second data base comprises a data card and said connection means comprises a data card reader and slot for receiving said data card.

17. The portable computer of claim 16 wherein a substantial portion of said data may be entered in said portable computer by physically touching said data entry as it is displayed on said screen to thereby provide simplified data entry for an operator.

18. The portable computer of claim 17 wherein said portable computer comprises a handheld computer, and said screen comprises a touch screen sized to cover substantially the entirety of its largest side.

19. The portable computer of claim 18 wherein said synchronizing means includes means for comparing the data entries in said two sets of data and replacing an older entry with a newer entry in the event of a mismatch in data entries.

20. The portable computer of claim 9 wherein said stored program includes means for displaying a plurality of nested shell displays on a screen, at least some of said displays including a plurality of data storage lines and a scrollable list from which an appropriate data entry may be selected for entry and display in one of said data storage lines.

21. The portable computer of claim 20 wherein said stored program includes means for displaying one of a plurality of maps on said interface, and means for displaying on said displayed map the indicated position of said portable computer corresponding to said GPS position data.

22. The portable computer of claim 21 wherein said stored program includes means for automatically entering GPS position data as the user enters other data to thereby associate said other data with a position.

23. The portable computer of claim 22 wherein said stored program includes means for a user to designate for display a desired position, and means for indicating a change in relative distance between a present location and said desired position.

24. The portable computer of claim 23 wherein said stored program includes means for user selection of an overlay for display on said interface, said overlay being specific to a particular class of data and having a particular associated set of menus dedicated to the class of data being collected.

25. The portable computer of claim 24 wherein said stored program has means for a user to display more than one overlay, said overlays being transparent, and wherein a user has access to only an uppermost overlay'"'"'s associated set of menus.

26. The portable computer of claim 25 wherein said stored program has means for said user to select an arbitrary random portion of a map for display on said interface.

27. The portable computer of claim 26 wherein said stored program has means for determining a plurality of map elements for display in that portion randomly selected by determining the vectors of each map element contained in said map and choosing for display only those whose vectors intersect or lie within said selected arbitrary portion.
