GPS

The course is still buried under 6 inches of snow and with the temps barely climbing above freezing for the next week, we are hunkered down working primarily indoors.  One of the projects we have been working on the last few days is our new irrigation map.  Our irrigation computer operates Rain Bird Cirrus, and one of its many features is a map which displays our irrigation components over a map of the golf course.  Since 1997 we have used a fairly basic map utilizing a hand drawn version of the golf course taken from our scorecard.


This version worked well for many years, but we could improve upon this map and accomplish a couple other things if we made a GPS based map.  Any course built in the last 12 years was likely GPS'd during the construction process.  We weren't one of those courses.

In working with the City's GIS department, we put together a plan to map and catalog ALL irrigation and drainage components, calculate yardages for sprinkler caps, and verify the actual size of all playable areas.  It sounds simple, but the last piece will be very valuable for future project estimating and pesticide and fertilizer planning and calculations.  All of the pictures are of #14 and #15.

Wish they took aerial photos in June, not March...
To start we borrowed a Trimble handheld data logger for basically the summer of 2010 and began collecting data.  The data collection process was completed outside of normal maintenance duties, so it took a better part of a season.  We mapped sprinklers, valves, electric valves, splice boxes, drain basins and cataloged each by type, size, brand, model, and date installed. 

Any and all traced areas can be quickly measured
 
The completed GIS map, the yellow dots are sprinklers with yardage, the red dots are front center and back of each green.  The yardage info can be displayed in a tighter extent, pretty handy for replacement purposes

The second portion of the project was to define/trace various areas of the course (ie greens, rough, bunkers, etc).  We completed this portion during the winter of 2010.  To bring the new map over to our irrigation software, we enlisted the help of Brian Keighin, Owner of Irrigation Technologies a local irrigation designer, consultant, expert.  With his knowledge of both ArcMap, Auto CAD and Cirrus he was able to help us take the data from GIS into Cirrus.  The result is an aerial photo with dots representing sprinklers in their exact location.  Not quite done yet...

The dots are just dots at this point, stations from the database still need to be added to make the map usable in Cirrus

Looks a little bare without the shading.

Completed map in Cirrus
The last piece of the project was to populate our Cirrus map from our database, which basically entails placing individual "stations" where they belong on the map and labeling them properly.  I have a dozen more stations to add and the map is completely finished.  A nice added feature we incorporated was to display the address of each home bordering the course so that when a homeowner voices a concern we can quickly identify where they live and address the problem properly. 

We want to thank Joe Simpson, Dave Murray and Sandy Malesky in Community Development for all of their help in making this happen.  They were great to work with and excellent in explaining things in layman's terms so we grass-guys could understand.
