High Speed Digital Audits

1. High speed data capturing platform;
2. High volume audit platform;
3. Data publishing platform;
4. Mobile monitoring and updating platform.

The HSDA platform as a technology has successfully been applied to and implemented in the following applications:

• Road Audits
• Property Audits
• Service Delivery Monitoring Audits

For more information on the above applications of the technology, please refer to the Asset Management and Government Solutions sections of this website.

Step 1 - High speed data capturing 

The data capturing or survey platform (the term survey is used to refer to infrastructure capturing) is essentially a communication hub that integrates various digital sensor data. All data is time stamped and geo-referenced on capture and is stored in an uncorruptible format.  The HSDA platform can be deployed an a variety of vehicles, including:

1. 4x4 motor vehicles;
2. Motorcycles and quad-bikes;
3. Human with a backpack; and
4. Fixed wing aircraft.

The most important data sensors supported by the HSDA platform are:

1. Up to 8 high definition video cameras (up to 5 megapixel and 20 frames a second per camera) providing a 360 degree view. Camera positions and quality is customized as per requirement.;
2. High precision differential Global Positioning System (GPS);
3. GPS assisted Inertial Navigation System (INS) to provide up to 10cm accurate positioning, even when GPS fix is bad;
4. International Roughness Index (IRI) sensors on road vehicles;
5. Carbon emissions and air quality sensors;
6. Laser profiling equipment;
7. and many other sensors as per requirement of client.

The software and methodologies used in survey process is designed to ensure completeness, that is, it ensures that the data capturing process is conducted in such a way that all the relevant data is captured, even if no prior information about the data is known. The system is therefore very flexible; it can use prior information about the target data or start from scratch with no prior information about the target data to be captured. 

Step 2 - High volume auditing

Data from step one is transported to our world class data centre and imported into our auditing platform database. The data can be available for audit as quickly as one day after the data has been captured. Our audit centre has a high numbers of trained personnel with the knowledge to mine and audit on the captured data streams. Depending on the application and the user requirement, the audited data can be available as quickly as one day after the data arrived at the audit centre. The audited data goes through a quality assurance department which verifies that the audit was complete and accurate after which the audited data is published.  

Step 3 - Data publishing

Once the audit is completed and quality assured, the data appears on our Visual Geographic Asset Management System (VGAMS) publishing platform together with the modules required by the client. The VGAMS platform has various modules out-of-the-box that provide clients with instant functionality related to reporting and asset management. The VGAMS platform is however customizable to provide maximum benefit to the client.  

Step 4 - Monitoring and updating

Because of the service orientated architecture of the VGAMS platform and our asset management mobile device applications, monitoring and updating assets becomes a reality. The following can be monitored and updated with simple mobile devices that can be issued to sub-contractors or consulting specialists:

1. Condition;
2. Development progress;
3. Maintenance progress;
4. Expenditure verification;
5. Payment authorization;
6. and various other applications that require up-to-date data.
