Help needed

1) We have lidar data for 2 new maps near Quincy.
2) We have some awesome terrain South of Cle Elum (2.5 hours drive time) for at least 2 maps.
3) Two maps close to Seattle in works (one likely to be cancelled).

I need help with field work.

Home-brew field work guidelines

We are getting ready to do some fieldwork in PNW Cascade foothill forest (think Tiger Mt. and similar).
I have prepared a contour+some trails map.

We will try to split the fieldwork; we are not qualified mappers; the end result is a "race-able" map.
This is the process description:

  1. I will visit the area before hand and try to leave reference markers. Hopefully GPS coverage will be good.
    1. Thus I will have exact reference points on the map
  2. I will distribute the area by giving a proposed trajectory to those participating.
  3. I will print out the maps in twice the scale of the final version (e.g. 1:10000 will be printed as 1:5000)
  4. Information gathering protocol:
    1. GPS is always on
      1. I have means of putting GPS trace on the map very easily.
    2. When on field, follow route on map and add features to it
      1. Use 3 colors 
        1. Use 2 usually, use third sometimes. 
        2. more colors is messy and takes too much time
      2. Vegetation is encoded by the following number scheme:
        1. 0 - open forest (corresponds white map)
        2. 0-1 - open forest, bad undergrowth (white map, sparse green stripes)
        3. 0-2 - open forest, very bad undergrowth (white map close together green stripes)
        4. 1-, 2-, 3- correspond to different runnability of forest. 
          1. 3 is reserved for blackberries and places you would never go yourself. 
          2. 1- and 2- are somewhere in between
          3. 1- and 2- can be combined with the undergrowth symbol. 3 cannot
          4. In PNW forest 1- and 2- can happen with fallen trees or smaller trees.
          5. -1 and -2 describe the usual undergrowth in different forms of baddness. 
          6. 2-0 is most likely to be used (and not 2-1). 2-2 is 3, 2-2 is not. 
          7. 1-0, 2-0 is very unlikely either, there is always some undergrowth
          8. 2-1 and 2-2 is questionable. 
        5. So the most common are:
          1. 0, 0-1, 0-2, 1-0, 1-1,1-2, 2, 3
        6. Please write them down as 0-2 or 0/2 
      3. Pointwise features shall be kept as numbers that start with 10 and a list of the features on some side paper. 
      4. Linear features:
        1. Distinct vegetation boundaries shall be kept with dotted line with first color
        2. Trails will be drawn as on map with first color
        3. Water features will be drawn with second color
        4. Contour line changes (hopefully not to be done), with third color. 
      5. Area features:
        1. mark a region and add an explanation in the features list. 


This is a document in making and I expect changes as we go along.

OCAD for Homebrewing

There are some tips and tricks that make home-brewing OCAD editing much easier. Most of them can be found in the internets, but I have not seen nice sources.


  1. Hiding of symbol
    1. How:
      1. Select an object or symbol
      2. On keyboard: F4. 
      3. All of the objects with the given symbol disappear.
      4. Do what you need to do
      5. select the symbol that was hidden.
      6. Click f2.
    2. You can do this also do a group of symbols - select everything and say F4
    3. This is useful for doing work in complicated/dense areas where lots of features are not allowing to draw clean lines. For example, when you are in a steep section with lots of contour lines, you may want to hide them.
  2. Following another line
    1. Why: 
      1. there is a road somewhere and you need to have green on one side and yellow on other.
      2. you don't want to get the green on the other side. 
      3. and you don't want the green to be away from the road.
    2. How:
      1. start drawing the line.
      2. press control, keep pressing it.
      3. click with mouse (left button) on the line you want to follow and keep holding it
      4. now move the pointer to the place till which you want follow
      5. release mouse
      6. the new line should be following 
    3. Sometimes even with this feature you can see tiny white line. OCAD has bugs.
    4. Once you have two lines together and you need to shape them somehow together, you are in bad luck - I do not know how to do that nicely.
  3. Custom shortcuts:
    1. Why:
      1. once by computer, you need to be working fast, don't waste time
      2. use shortcuts!
    2. I use the following:
      1. ctrl+d for duplicate in place (fill, make border, duplicate identically in object menu)
      2. ctrl+f for forcing a different symbol (usually duplicate in place, then choose a symbol and then force a symbol on top)
        1. this is useful when creating borders of sorts or just making some contour line a lake or similar.
      3. ctrl+r - for reverse a feature - if you have a cliff with ticks to one side, this is how you can get them to another
      4. ctrl+t - for removal of vertices 
    3. This was mentioned here.

Usage of NW trails/Switchbacks data

In some of the Homebrew maps I have been using NW Trails data - it has been in most cases used as a reference, but nevertheless, it has been.
So I need to give proper attribution.

Quincy 2 days have finished!


Excellent racers, excellent volunteers, excellent weather!

Quincy West:


Fast courses with shorter legs.
Some confusion was caused by Finish on first day - "Navigate to finish" says the description sheet.

Quincy South:


Some longer route choices with a mix of shorter legs.

2.5 or 5 meters?

2.5 or 5 meter contour lines, that is the question.

Thoughts?
I think I will go with 2.5 meter ones.
