See if there is a GIS data clearinghosue in your city/county/region. Lots of universities host that kind of information.
I work shoulder to shoulder with the County GIS guy. We outsource a "fly by" aerial photography group because I live in a pretty small community. Our latest aerial map was done early last year, but the is a bad shadowing problem in the area that I'm looking at because of the sun location. I honestly don't think that I'm going to find any better mapping because I've checked almost every site that I can think of, including google earth.

Shadows are a big problem with most ortho imagery. Satellite imagery is usually better. Have you taken a look at the LANDSAT-7 imagery for your area? You should be able to find a non georeferenced version of it. Otherwise the GIS person will have to take care of it. What kind of data repositories do you have available publicly? If all you need is a clipped full color image, I can help you out if you send me to the data and give me an idea of what I need to clip it to.



What do you guys think about labeling the holes on the tee pads instead of the midpoints of the hole lines?

I like that, because the players is always looking for "Tee Pad N", not "The Middle of Fairway N".

I've looked but all I can find is from the 2007 aerial. It's not as bad as the 2012 aerial with shadows, but I guess I'm just asking for more detail than what if offered for a "po-dunk" town.

Agreed.
I can always save my old lines if that ends up being the way to go. It might take me awhile to label based on the tee pads because the auto labeling will be an issue. There are a few areas on the course that are crowded with features on the map.
And the mid line labels obscure the important vegetation data.

I will get around to putting in the update 1m cell size base image this weekend.
Still looking for a high end GPS unit to borrow. I need it for accurate elevation information.

Might want to ask about LANDSAT. There might even be LiDAR for your area. I doubt it will be the stuff I am fortunate to use. But you could get a surface model that shows trees. Then get someone to draw on it.
I really prefer the course maps that are 'hand drawn'. That I am doing is going to be close, but what you see under the trees is the most important. A giant tree with high limbs is no more of an obstacle than a large telephone pole.

So I've been busy.

I finally got out there with a highly accurate GPS unit. After processing it is accurate to 15-30cm with the trees and terrain. And it made a big difference it the usefulness of the map. The distances are spot on. And because of that, the elevation change is as good as it can possibly be. The elevation as measured by the GPS is not reliable. But when my points are good, I can put them over my DEM that is accurate to 20cm. For a course like Zephyr, elevation change is everything.

The map is now in its final version. It is more accurate than any map out there. And the base imagery is really unique. The map can be adapted to anything. A big course map at hole 1, or score cards, or just passed around the internet.

Here it is:



Here is a link to the repository for all of the mapping. PDFs, jpgs, printer friendly maps, and once I get around to it there will be numerous KMLs that you can play with on Google Earth.

https://sites.google.com/site/zephyrcovedgc/maps

As always, feedback is welcome. I know how to make maps to GIS standards.... aesthetics, graphic design, etc, is not my strength.

The table needs some work. It is just that, a table. I can't format it like Excel, and wrap text, change alignment, etc. I want to change 'Name' to 'Hole'. But all of that comes straight out of the data and updates nicely. Except for the field aliases. I could put a better formatted table in as a graphic, but that would cause problems with making the map larger or smaller. The values in that table were rounded to the nearest 5 or 0. No one cares if a hole is 322.8ft. I was going to make everything in meters to torture people who don't like the metric system...
The jpg compression also sucks and the colors are off. The best view of the map is with a PDF. The yellow basket icons might need to be tweaked.
There is also a Douglas Adams reference in the map.

Wow pineappaloupe! That is some nice detail. Obviously I've been busy over the summer & missed out on the timing of this thread. That aside, I can share something I did for further ideas (see link).
https://drive.google.com/file/d/0B-x...JWUUhVVjQ/edit

I have done similar for other local courses with the thought to see what layout detail works best. I find courses w/ lots of trees as per 1st 9 holes of the example have too much forestry if using a satellite view backdrop. Thus, I use representative shapes for tees, baskets, trees/obstacles, and rough or off-fairway areas. The flight path detail is the typical although each person will choose their own once at the tee.

The idea is to give the user the "lay of the land" for the DG course enough to play the game more so than finding the tees & baskets. And, its really aimed at those unfamiliar w/ the course. I would love to be able to get the terrain/elevation detail into the maps and will have to look into that a bit more.

For my maps, I essentially take the GPS-points while playing a game, maybe a few pics for obstacle detail, then bring them home to show on Google Earth or one of the map apps. I'll take some screen shots to stitch together a JPG/backdrop in MS-Publisher or other graphic app then draw in the graphic items of tees/baskets/etc over the backdrop as per GPS-points as shown in GE. Then remove the backdrop & export course detail as JPG-file. The JPG-file can then be printed as PDF/etc or imported to a KMZ-file to GPS-enable it.

If you wish to GPS-enable any map made to scale (so users can see their location on the course), you import the JPG-file to a KMZ-file using freeware app "Kml Builder" (lets you move it in position over the land & add other details). The above link is example of this ability. The JPG-file can be extracted using any compressed file reader (like WinZip/7zip/etc). With the map posted at hole-1 or wherever, the user can download the same via the QR-code.

There's a lot here for those not in the know of the GPS world or some of the file types but a few Google searches can help there. Those w/ GPS-enabled phones playing an unfamiliar course can appreciate the ability to use a GPS-enabled course map as a course guide.

Thank you for your work - it's amazing. I love Zephyr Cove and really appreciate we have a map now.
More people should experience how great this course is and your map will help. Thanks again!
