$362.33 Left to Reach our Goal!

Every year we run a fundraiser to cover the cots of the server for the next year. This last year we had to upgrade servers due to an attack and the costs are a little higher, but as you can all tell it is much faster and much more reliable.  VERY IMPORTANT even though myZIP is reduced to 1MB you can still download courses and libraries by clicking on the course or library name on the Download Tab.  We need to raise $2,500 in order to increase everyone's myZIP size back to 30 MB and for those who have donated in the past once we reach our goal your myZIP file size will be increased back to 1GB. Members who made a donation of $5 or more in the last 30 days have already had their's increased. We recommend a donation of $25 however every dollar counts, however to increase your MyZip size you need to make a donation of $5 USD or more. PLEASE MAKE SURE YOU ARE LOGGED IN BEFORE MAKING A CONTRIBUTION.

Hi, please help. For me is not running National Map Viewer :( on http://viewer.nationalmap.gov/viewer/ (still "loading"...).

Can anyone generate GeoTIFF for this location?
1) 50.8618875N 14.2689692E
2) 50.8569603N 14.2836517E

I wanna try modeling my home 9-hole course for my playing in TW08.

I´m czech, so sorry for my english.

If you can send me this, please do it to my mail adress: martinix06@gmail.com

I have some free geoTIFF of czech republic (complet CZ area), but i don´t know, how i must set this coordinates to export file to UTM for use in TA.

Thanx to all, who can help me.

Thank you so much, but relief detail is not too detailed and accurate. There isnt geotiff with orthophoto layer too.

Any other idea or help?

I used to use this

http://www.coursedownloads.com/forum/posts.asp?post=8124&forum=14

then Google changed things and I could not get it to work. It was never very accurate data (90m I think). The USGS site is good for USA courses, but the rest of the world is not very good.

Try this site for SRTM

http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/

but again I think it is only 90m.

Good luck with your project

Thanx :) How can I use only a part of HGT file in 3DEM? I try "select smaller area" -> "Convert to UTM projection" -> "Save Terrain Matrix" with ASCII. But TA say me "Runtime Error 7011 - Matrix Dimensions illegal at line 683" :(( and quitting.

I need .HDR file for these coordinates:
1) 50.8618875N 14.2689692E
2) 50.8569603N 14.2836517E

Can anybody send me HDR and TXT for this coordinates? (For use in TA)
And specify which format is it (10m, 30m or SRTM-3), please?


Thank so very much for your pleasure.

Mail is: martinix06@gmail.com

Tony you are doing things in the wrong order in 3DEM, you are selecting a smaller shape too soon, download and read this tutorial

http://coursedownloads.com/extras/details.asp?id=719

You will also struggle to get an area accurate to so many decimal points, I could only ever manage 4 decimal points and then they were not always spot on.

So... i have new coordinates:
50°51´43"N 14°16´7"E
50°51´24"N 14°17´3"E

I have coordinates from google earth, as well as foto image, converted to TGA in paint.net.
I donwnloaded file N50E014.hgt.

In 3DEM i select smaller area, change to UTM and save matrix as HDR (in attachment).

But in TA if i wanna import HDR, the app is crashing with this:
"Matrix dimensions illegal"...

Can help me?

The fault was too small area i think.

Now i create area:
50°51´47"N 14°12´57"E
50°51´19"N 14°17´10"E

This is ok for import to TA. TA say: create flat plot 1560 x 980 yards exactly.
CA want dimensions in meters. So i tansfer yards to meters and dimensins are 1426 x 897 meters.

When i export 3dem to flat *.tca file (1426x897 meters), CA is falling down.
If i create flat 1560x980 meters, CA open it, but clay is very deformated.

Can help, how big i must create flat plot in meters for this area?

Must be done in this order
Convert to UTM projection. Go to Operation=>Change Projection=>Change UTM Ellipsoid … make sure that you check NAD27 and hit OK. Go to Geo Coordinates and check Minutes of Degree (if that is what you are using). Now go to Operation=>F6 Resize Overhead View and move the slider about 2/3 of the way across. The program will take a few moments to re-render the zoomed-in image.
Go to Operation=>F8 Select Smaller Area and find the top left corner of your plot. Click at that spot and then drag to the exact
coordinates of the bottom right corner of your plot, or as near as possible. Hit enter. Now you just need to save the data. Go to File=>Save Terrain Matrix=>File Format … select ASCII Text String and hit OK. Now you have your DEM data. Open up TA and check SRTM, load the DEM and the image

Open Course Architect to create another plot. Once you get to the part where you can see the heading View click on it, then uncheck metres which is the bottom item. You can then recreate your plot in yards as per the request from terrain assist.

Good news that you got it to work. I will certainly try your course once it is completed. Happy course designing.

So... designed plot looked good, but lanscape relief disagrees to relity :(
Now im in the end. Coordinates is OK, overlay image too, but relief isnt as real.
It may be that 3DEM not enough detail?

How i can modelling plot for use in CA manual? Which software is good for this?
I would like to plot modeled on the basis photomap. As i know it from relity.

This is about only way :(((

That is the problem with the height data for International courses, I have never found it to be very accurate. I presume that you are saying that it will be better to work from a flat plot. If this is how you want to do it, then still use the 3DEM material that you have but when you have drawn some shapes in Terrain Assist just export them to the flat plot that 3DEM asked you to create as it''s 3rd stage. Whatever you rename it to just keep using that plot.
