Further, the present invention provides a method for managing location surveying data (100). A new user may register or logging in to the system for accessing and using said system for their project. The method preferably starts with step (1 10) by creating a project for surveying a location. A first user having an access to the first level unit will create a project which includes surveying a specific location for underground utilities services upon request. Then, the first user enters information related to the project (120) onto the first level unit. The information includes, but not limited to, details and instructions, location and diagrams of the project. Further, the first level unit may add planned point on the entered or uploaded diagram.

The first user will then assign a second level unit to proceed with supervising the surveying project. The project information uploaded onto the first level unit is transmitted to the second level unit (130) upon assignment of the second level unit. A second user having an access to the second level unit will then configure the global offset information for the project. Then, the second user transmits the project information to the third level unit (140) upon assigning the project to the third level unit.

A third user having an access to the third level unit will then conduct and execute the project by surveying the location (150) according to the assigned project upon receiving approval from the second level unit. The third user measures the GPS value for base, planned and unplanned point. The surveyed data will be collected and recorded (160) into the third level unit.

The recorded data will then be synced (170) to the center unit which are accessible by the first and second level unit. Subsequently, the third level unit which comprises the check code generator will generate the check code (180) in accordance to the recorded data. The third level unit will then send a verification request to the second level unit for verification and validation of the recorded data (190).

In a preferred embodiment, the second level unit may reject the verification request from the third level unit if the recorded data did not meet certain requirements of said project. In an exemplary embodiment, the third level unit may generate a map which annotating the measured point based on the recorded data.

Fig. 2 is a flow diagram showing a method for generating a check code based on the recorded data (180) in accordance to an embodiment of the present invention. Meanwhile, Fig. 3 is a flow diagram showing a method for generating a second code based on the project reference index (186) and Fig. 4 is a flow diagram showing a method for generating a check code based on the first code and the second code (188) in accordance to an embodiment of the present invention. Upon recording the surveyed data into third level unit, the check code generator of said third level unit will then generate the check code based on the recorded data (180). The method for generating the check code (180) preferably starts with the step of converting the recorded data into specific numerical values (182). The recorded data are converted into, but not limited to, non-negative integer values using pre-defined formulations for each recorded data. In a preferred embodiment, the formulations for converting the recorded data are defined as follows:

Latitude

Common GPS device provide values of latitude for a location in radian format with 1 mm as a resolution unit. The data is converted to a degrees minutes seconds format and then, said converted data is calculated by the following formulation to generate the non-negative integer value.

[(deg+180)((10^A8) + min)((10^A6)+sec)(10^A4)]

where:

deg = degrees value of latitude;

min = minutes value of latitude; and

sec = seconds value of latitude. Longitude

Common GPS device provide values of longitude for a location in radian format with 1 mm as a resolution unit. The data is converted to a degrees minutes seconds format and then, said converted data is calculated by the following formulation to generate the non-negative integer value.

[(deg+180)((10^A8) + min)((10^A6)+sec)(10^A4)]

where:

deg = degrees value of longitude;

min = minutes value of longitude; and sec = seconds value of longitude.

Altitude

As the common GPS device provide values of altitude with 1 mm as a resolution unit, the altitude data is first converted into 3 decimal values in unit of meter for example:

1 mm = 0.001 m

Then, the converted altitude data is multiplied with (10^L3) to generate non-negative integer value which represent the altitude data.

Time and Date (Timestamp)

The time and date of said data measurement is first converted into milliseconds. Next, the converted data is truncated to generate the non- negative integer value by dividing said converted data with 1000.

Whereas, the data for the type of utilities services, capacity of utilities services and type of coordinate measurement are represented by numerical value. The numerical values are, but not limited to, non-negative integer value.

In an exemplary embodiment, the recorded data for the measurement of invert level for low voltage power cables are represented as numerical value according to Tables 1 -3 as follows:

The type of utilities services which is power cable = (01);

The capacity of utilities services which is low voltage = (01 ); and

The type of coordinate measurement which is invert level = (01).

Hence, each of the data is represented as (01 ) for the type of utilities services, (01 ) for the capacity of utilities services, and (01 ) for type of coordinate measurement respectively.

Upon completing the step (182), a first code will be generated (184) based on the non-negative integer value to represent the recorded data. The non-negative integer values which represented each of the recorded data are being summed up to generate the first code.

In a preferred embodiment, the formulation to generate the first code is defined by:

[(a) + (b^*2) + (c^*3) + (d^*4) + (e^*5) + (f^*6) + (g^*7)]

where:

a = longitude integer value;

b = latitude integer value;

c = altitude integer value;

d = type of utilities services integer value;

e = size of utilities services integer value;

f = type of coordinate measurement integer value; and g = time and data integer value.

Subsequently, a second code is generated based on other variable which is the project reference index (186). As shown in Figure 3, the steps for generating the second code from the reference index (186) preferably starts with converting each of said reference index characters into a specific code unit value (186a). The specific code unit value is, but not limited to, a 16-bit Unicode Transformation Format (UTF-16) code unit value.

The code unit value is further multiplied with a string of value (186b) which is, but not limited to, an index value plus 1. Next, the multiplied code unit values for each of the characters are added up to generate the second code (186c).

In a preferred embodiment, the formulation to generate the second code based on the project reference index is as follows:

ID. charCodeA t(i) ^* (i+1)

where:

ID.charCodeAt(i) = converted reference index characters at given index; and / = index value.

Upon generating the first code and the second code, a check code is then generated based on said first code and second code (188). The steps for generating the check code preferably starts with defining a pre-defined code based on the first code and the second code (188a).

In a preferred embodiment, the second code is multiplied with (10^L12) to conform with the maximum number of digit of said first code which is 12. Then, the second code is added up with the first code to generate a pre-defined code. The pre-defined code is defined by formulation as follows:

[(Y^*( 10^L2)) + (X)]

where:

X = first code; and

Y = second code.

Further, the pre-defined code is converted (188b) into sixty binary conversion values by using the decimal of said pre-defined code. Next, the converted pre-defined code is hashed (188c) to generate the check code via, but not limited to, Secure Hash Algorithm 1 (SHA-1 ).

The above-mentioned system and method for managing location surveying data is well-equipped with security feature which protect the recorded data by tracking and tracing any changes of the recorded data. Further, the data are recorded in specific variables or formats for easy reference. Also, the system enables the user to validate the originality and accuracy of the recorded data by having the check code. Furthermore, the system and method for managing location surveying data as disclosed is user-friendly in which a specific role can be assign to a sub-user for carrying out the surveying process.
