- Power source 330 may be any type of power supply device able to provide sufficient power and preferably be of dimensions suitable for use in a handheld device. If power source 330 does not provide the correct voltage, then one or more voltage converters may be fitted to allow for correct power supply characteristics to various internal components of survey device 300.

- Microcomputer 305 is provided with software applications that can be set for automatic shutdown if microcomputer 305 remains idle for a predetermined period of time. Separate software can also allow survey device 300 to be shut down and reset, for example using a display module 345 of survey device 300 as a user/device interface.
- Survey device 300 and an associated software application (i.e. computer program product) executable on microcomputer 305, allows an operator to capture spatially accurate data and combine the spatial data with environmental data relating to conditions or characteristics at a sampled position.
- the software application utilises software job keys with a time expiry, which forces operators to synchronise survey device 300 with a central database 350, which is not part of survey device 300.
- This synchronisation is achieved by using a database synchronisation software module 335 and by connecting the microcomputer 305 to a computer or server containing or in communication with central database 350.
- the connection could be obtained by a physical connection 360, such as a cable, or via wireless data transmission means as previously described.
- Survey device 300 is additionally preferably provided with a mobile phone module 365.
- mobile phone module 365 can be used to transmit data from microcomputer 305 or memory to database 350 when survey device 300 is remote to database 350. This allows collocated data to be remotely transmitted to database 350 whilst an operator continues to conduct surveys in the field.
- Survey device 300 can also be provided with a protective casing 370 which is preferably substantially water resistant. Connection 375 for external antenna 320 can also be provided as illustrated in Fig. 4. Various connections 380 can also be provided for connecting external collecting or sampling devices. [060] Referring to Fig. 5, there is illustrated a method 500 for operation of software 385 provided in survey device 300. To initiate software 385, the software is selected at step 505 from a startup menu available on the microcomputer. Once the software has been started the data is synchronised at step 510 with database 350, either by physical connection or remote access. During the synchronisation process, microcomputer 305 receives a number of job keys from the database.
- job keys received at step 515, have a time expiry attached to them which preferably forces the user to synchronise with the central database prior to the job key's expiry time. It is also possible to download predetermined sampling locations and information about the predetermined sampling locations including spatial data (y, x, z), together with conditions associated with that position (aj, a 2 , a 3 , ...) from the central database during the synchronisation process. This is illustrated at step 520.
- sampling location has been predetermined and is a known location (step 525) then the position and/or the environmental data are located at step 530 in the database. If there are no predetermined sampling locations as illustrated at step 535, the user can locate the desired sampling position and then log that particular position using the GPS module
- step 540 Once the sampling position has been found, it is possible to then input the required environmental data that relates to that position at step 545.
- the data collected from a particular position could include, for example: soil colour; soil type; vegetation type; geographic features; management features; or a wide variety of other types of information.
- step 550 If survey device 300 is within mobile phone coverage, it is then possible to upload the collected data to the central database, combined with the sampling position, and thereby synchronise data in microcomputer 305 with the central database 350. This is illustrated at step 550. Alternately, if there is no mobile phone coverage or if the data is not required at the central database for a particular reason for some time, the data can be stored in memory to be synchronised with database 350 at a later time, as illustrated at step 555. It is possible to synchronise the data with the central database either physically or remotely at any point in the future prior to a particular job key's expiry date. [063] Once the synchronisation has been completed, that particular job is identified as finished at step 560.
- microcomputer 305 should be synchronised with central database 350 prior to continuing. Once further job keys have been uploaded from the database or associated server, it is possible to continue onto other sampling locations.
- a local database may be provided in survey device 300, associated with microcomputer 305, and can allow the capture and storage of both the spatial data and the environmental data that has been collected, and thus enables the user to synchronise this data with a larger central database 350.
- reports can be generated concerning the spatial data (y, x, z) and the associated environmental data (a 1; a 2 , a 3 , ...), together with the time of data collection which can be automatically logged and combined with or appended to collocated data sent to database 350.
- collocated data may be obtained in the form (t, y, x, z, aj, a 2 , a 3 , ...) where t is the time of sampling.
- the time of data collection could be obtained from a variety of sources such as an internal clock of microcomputer 305 or via a signal received by an antenna of survey device 300.
- the software interface provided within the device is a VB.NET/C#.NET Windows compact framework application which interfaces with a SQL Server CE database for use on Windows CE platforms.
- the GPS operational software may be StormSource.GPS.
- OpenNETCF. Multimedia. Audio software can be provided within the survey device to run audio visual help files. Example pseudo code that can be used to enable the GPS satellites and begin receiving GPS signal is presented hereinafter.
- the survey device can be utilised in a wide variety of applications, including but not restricted to, for example: Mining; Agriculture; Tourism; Education; Inventory control; Sales; Government; military; Medicine; Survey; Real Estate; Human Resources; Law Enforcement; Emergency Services; Building Industry; Fisheries; Forestry; National Parks; recreation; Engineering; Roads and Traffic; Environmental Monitoring; Geology; and/or Seismology.
- Optional embodiments of the present invention may also be said to broadly consist in the parts, elements and features referred to or indicated herein, individually or collectively, in any or all combinations of two or more of the parts, elements or features, and wherein specific integers are mentioned herein which have known equivalents in the art to which the invention relates, such known equivalents are deemed to be incorporated herein as if individually set forth.
