QA/QC Philosophy not words!

Suppose you are about to – or already have – contracted with a reputable and qualified Geospatial Data Provider on a large project. Is your organization knowledgeable, experienced or capable of reviewing or managing such a complex endeavor? 

Ask yourself these questions:

• Do you have both human & system resources required to review the deliverables when they start streaming in (which they will in mass quantities on large projects)?
• When the AeroTriangulation reports are delivered, who in your organization will review, understand and approve this vital deliverable?
• Will you just simply trust your mapping contractor because they claim ‘…we guarantee the results’?
• Do you understand that you may not see the gross errors in the final data until months or years down the road when you and other agencies are using the data?
• Where will your mapping contractor be then? Will they still be there to fix the data?
• Will there be litigation in order to correct and resolve the errors?
• Will you be pointed out as the “failed project manager”?

Don’t manage a project with complex and costly deliverables on your own unless you have the resources to successfully do so. Axis GeoSpatial has certified project managers, certified photogrammetrists and other trained professionals to assist you in managing your geospatial project to a successful and reliable completion.

Not only do we possess the production equipment and expertise, we dedicate QA/QC tools and personnel that specialize in Quality Assurance. Because we understand all aspects of geospatial production including common errors and omissions, Axis can more easily and reliably identify issues and further communicate more effectively and cooperatively with your mapping contractor. We also can do it in a timely manner thereby mitigating scope creep and scheduling delays.

Get the second opinion – view the quality of your GeoSpatial Data through our eyes.

Field QA/QC Process

As a routine process of a project, Axis calls upon its in house survey team to not only provide precise and accurate survey control for photogrammetric and airborne LiDAR data sets, but to also provide the true analysis and cross checking of those datasets. 

Once a project has been controlled and adjusted to the ground and appropriate project datum’s, additional points of interest are identified, typically by project geometry or guided by project specifications requiring checks in different ground cover classifications. This last method involves identifying land cover and use classifications, such as wetlands, deciduous or coniferous wooded areas, cultivated areas or residential areas and then gathering specific data points in those areas to assess and verify that the location and elevation data represented by the airborne dataset is correct. This procedure involves establishing GNSS control, and then precision stakeout of a point of interest to verify its three-dimensional location.

Documentation of this process includes gathering metadata that will show measurement details, control ties, conventional photographic evidence of the general area, as well as through the scope of the instrument to prove aiming accuracy. Through the scope photographs are directly linked to a point of measurement, and include the display of the instrument crosshairs as they are pointed at the prism or point of measurement.

Rain Rain Go Away! Have you ever seen so much rain in such a short period of time?

Has recent flooding created an immediate need for accurate, detailed topographic data?  HD-LIDAR services could provide the solution you need.

LiDAR survey can capture terrain to provide a high accuracy data set of both LiDAR and imagery data so you can see where the water caused the greatest damage and assist in planning for future flooding issues.

With this technology we can turn around the delivery of huge volumes of collected data in days which would normally take several weeks.

Technical Checklist when hiring an aerial mapping professional

Some technical things to make sure you are getting from your aerial mapping professional include the following:

• Proof of certifications of project managers or responsible professionals
• Certificate of Insurance
• Exacting scope of work for project, including identification of project datum’s, work area, accuracy requirements, metadata and related documentation
• Aero-triangulation and survey control reports, network adjustment etc.
• Camera, lens, sensor and equipment calibration reports, as well as serial numbers of equipment used, and technical flight data
• Trajectory reports for airborne IMU/GNSS data
• Statement of conformance to accuracy standards, whether they are client generated, or nationally accepted standards.
• Deliverables and data, including contact prints, digital orthophotos and other files, as well as PDF or hard copies of drawings
• Proof of surveying methodologies, including equipment used, control ties, control point datasheets, control diagrams and reference ties, photographs for measurement point confirmation and placement of markers at the point of observation for QA/QC follow up observations

Expand the services requested

Finally, don’t be afraid to expand the services requested. Our staff includes personnel that bring special skills to the table, including compiling data in AutoCAD, MicroStation, and proprietary GIS formats. On the surface, an engineer may need hard data for his design, but much of the data that is collected during a mapping project is directly usable in a GIS database. Utility mark-out can now easily be seen in our imagery when it is planned for, and the ability to mine our imagery and LiDAR datasets for additional information is not widely appreciated.

Contact AXIS today for any of the above on your next aerial mapping project.
