GPS Mapping, Satellite Imagery, Aerial Photography and Contour Mapping Services

Does your course have an accurate current as-built of the irrigation system?

More than likely not.  It is probably less likely that you have a current and accurate aerial photograph or satellite image.

Nearly anyone associated with the golf course can benefit from an accurate as-built and especially and aerial photograph or satellite image.

Superintendents – For a superintendent an accurate as-built drawing of the irrigation system is critical to the daily and operation, troubleshooting and maintenance of the system.  Additionally, the ability to know the accurate area calculations of all the golf course features such as greens, tees, fairways, roughs and bunkers is critical to properly purchase materials and apply fertilizer and chemicals.

General Managers – The aerial photograph can be an extremely valuable tool to the General Manager to help in planning and communicating with the staff, boards and membership.

Golf Professionals – Golf professionals can use the aerial photograph to assist in tournament preparations as well as daily play alerts.

Boards – Boards will find the aerial photos beneficial when they are evaluating the long-range plans and activities of the management staff.  they are also every effective in helping explain new projects the club may be soon undertaking or voting upon.

Membership – The membership will find them interesting and beneficial to help know their course better and show to their friends who may be joining them for a round. 

Architects – Architects will find them extremely helpful in their long-range planning and design strategy as well the ability to add existing contours.

The Process

ATI combines Satellite Imagery or  Aerial Photography along with GPS mapping to provide the most accurate and visually rich as-built available.

In order for the GPS mapping of the irrigation, drainage or other points such as sprinklers, valves quick couplers and drain inlets to be accurately overlaid on a satellite image requires the satellite imagery or aerial photography to go through a special “orthorectification” process.  Orthorectification is a process in which aerial photos are adjusted to correct distortions due to topographic relief, lens distortion, and camera tilt.  These geometrical corrections will mean that the scale of the photograph is uniform.  Unlike an uncorrected aerial photograph (Google Earth), a orthophotograph can be used to measure true distances, angles and areas.  This orthorectification takes the curvature of the earth out of the satellite image and flattens it so the GPS and  image accurately match.  We have access to such imagery in most areas of the world. The resolution and quality of the photo allows for a very clear picture when zooming as you can see below in the image from a course in Beijing, China.  As you can see many different dates and cloud cover percentages can be available.

The services are available in a number of ways to meet your budget such as initially providing only the satellite imagery with the area calculations.  The irrigation and drainage points can be then added later at any time as funds become available.

Aerial Photography and Satellite Imagery Base Map With Area Calculations

ATI can provide new high-resolution satellite imagery or a flown aerial photograph of the entire golf course or property depending on your location. The photography will be used to produce a orthorectified image of the site with 0.5’ to 2′ ground pixels. AutoCAD drafting will then be performed on all site features to create a golf course base map. The map will include all the golf course features such as greens, tees, fairways, bunkers, roughs, landscaping plus cart paths, building locations, roads, bridges, driveways, water bodies, railroads, transmission lines, power poles, fences, and grouped tree outlines. A scorecard view of the total area (square feet or meters) of greens, tees, bunkers, roughs and fairways per hole is provided. The as-built drawings will be provided in color on individual sheets at industry standard scales, scaled to fit on a single sheet ready for wall mounting plus 11”x 14” color laminated sheets per hole bound in a book format. The data will also be provided in a digital format.

Option 1 – Irrigation & Drainage Component Point Drafting

ATI provides on site sub-meter precision GPS mapping of the following points:

  • Sprinklers
  • Mainline Isolation Valves
  • Lateral Isolation Valves
  • Quick Couplers
  • Specialty Valves
  • Satellite Locations
  • Wire Splices
  • Drain Inlets
  • Mainline Pipe Routing

Please note that the use of utility vehicle provided by customer. Also, all point locations must be flagged in advance by the customer prior to mapping by ATI.  Also, mainline routing must be painted on the ground in advance by the customer prior to GPS mapping.

Option 2 – Irrigation Pipe, Wire and Control Drafting

ATI provides AutoCAD drafting of the following irrigation components:

  • Lateral Pipe Routing
  • Station Numbers

Please note that GPS data from Option 1 is provided by ATI to  the customer for penciling-in of the lateral pipe routing and station numbers prior to drafting.

Aerial Photography and Contour Mapping

Proper land planning and golf course design requires accurate site and contour mapping. ATI can use the aerial photograph base maps or satellite imagery to produce scaled planimetric and topographic mapping with 1 foot, .5 meter or larger contour intervals based on your needs and budget. This will then be used to produce a orthorectified image of the site with a 0.5’ ground pixel. AutoCAD drafting and sophisticated software will be used to create a contour map of the golf course with elevations. All the features of the Aerial Photography Base Map will also be included.

Please note that either aerial photography or satellite imagery requires clear skies and proper scheduling.  Make sure you allow adequate time in your planning process to accommodate the process.  Additional time may be required depending on your location in the world.

GPS Green Contour Mapping

On some courses it is important during greens renovation to rebuild the green to the exact contours.  ATI utilizes precision GPS technology to attain all green topographic information at 1/10th foot contour intervals on putting surface including 5-10’ off the green surface.

 Please Note This Service May Not Be Available In All Locations

Deliverables

All drawings will be provided in color on individual sheets at industry standard scales, scaled to fit on a single sheet ready for wall mounting plus 11”x 14” color laminated sheets per hole bound in a book format.  The data will also be provided in a digital format.

ATI Attends China Golf Show in Beijing

The China Golf Show was held in Beijing MArch 22 – 24, 2013.  ATI was represented by Jim Schumacher, President of ATI and Thomas Muller of ATI-China.  ATI has attended the China Golf Show for many years and the activity and interest at the show seemed to be greater than in recent years.

Several architects were exhibiting and most of them were extremely busy.  The interest in the show can surely be attributed to the success of young Chinese golfers such as:

  • Shanshan Feng, major champion on the LPGA tour at the 2012 LPGA Championship
  • Andy Zhang, a 14-year-old who qualified fo the 2012 US Open
  • Guan Tianlang, another 14-year-old who earned a berth at the US Masters by winning the championship at the , Asia-Pacific Amateur Championship in Thailand in late 2012.
  • Lian Wen Chong, 2007 Order of Merit on the Asian Tour, the first Chinese golfer to make the cut at a major, The Open Championship at the Royal Birkdale Golf Club, and set a new course record at Whistling Straits with his 8-under 64 in the third round of the 2010 PGA Championship.

In addition, Greg Norman, former long time world #1 and winner of two Majors, has
been hired by the Chinese Golf Association (CGA) to act as a mentor and help
develop a training program for its young players as they try to qualify for Rio
Olympics.  Golf is obviously trending in the right direction.

Unfortunately, there are still many obstacles to overcome for golf to reach its potential development in China and most of Asia such as land acquisition, development cost and the lack of affordable public golf.   During the trip we visited a local driving range to find the facility brimming with new golfers.  The cost for 100 balls was $9, not exactly affordable for the average Chinese national or anyone for that matter.  Almost all the golf courses in China are private or extremely expensive as with most of Asia.  Until these obstacles are overcome golf will never meet its true potential in the region.

We are hopeful that with more success of Chinese golfers the government will join the cause and help provide affordable public golf to its’ citizens such as the many municipal courses available  in the USA and other parts of the world.
