Abstract
Working with the grid mapping utility of the present invention is an easy way to log GPS positions and GIS data at waypoints arranged in an evenly spaced grid. This allows a field user to gather measurements made by field sensors such as depth sounders, chemical detectors and magnetometers. The field user can then create contour maps with the necessary density of data while avoiding any gaps that might force the field user to return to the field.
Claims21
A method of recording field data by a user to facilitate the creation of a contour map using a handheld global positioning system (GPS) receiver comprising the steps of:
- setting up a grid network;
- forcing the user to enter data as GPS waypoints in the grid network;
- forcing the user to enter data as geographic information system (GIS) point feature descriptions in the grid network;
- and
- uploading the GPS waypoints and the GIS description to the GIS.
A method of creating a grid map on a computer to be used by a handheld global positioning system (GPS) device, comprising steps of:
- setting up an evenly spaced grid network comprising uniformly spaced points, referred to as grid waypoints, respectively oriented in rows and columns;
- requiring entry by a user of values at said grid waypoints, referred to as point features, to be used by a user using the handheld GPS device to perform measurements or observations.
A method of entering data from a handheld global positioning system (GPS) device into an evenly spaced grid network comprising uniformly spaced points referred to as grid waypoints on the handheld GPS device, the grid network being generated on a PC-type computer, comprising the steps of:
- setting up the grid network;
- and
- requiring entry by a user of values at said grid waypoints, referred to as point features, to be used by a user using the handheld GPS device to perform measurements or observations.
