Mappers Blog: Uaul Grond Setup

1: The plate
The plate itself consist in a plexiglass sized a little bit more than A4. It is not the lightest solution but I like the hard surface to draw on. The base-map consist in a gray-scale print. On the base-map there are contours 1m as clearings both extracted from laser data. The base-map should be readable but kind of disappear when the field-notes are drawn. I always place a set of symbols on the base-map, making it easier to me to draw them the right size right away. Also a mesh I add to facilitate the import of the field-notes into the OCAD (Some more details here). The base-map is taped on the plate with simple transparent tape. As for the film I started to work with the common (Ritfilm 50micron A4) replacing the one propagated in Switzerland (adhesive). The common is six times cheaper, has no real disadvantages but some advantages: You get it everywhere, the base-map disappears better while drawing and scanning  and after removing it from the base-plate, you get it in a form practical to store. The film I tape on the plate with the same common transparent tape. 

2: Noise reduction
I believe the big czechs use a kind of curtain to curtail the  field one actually works with on the map. I tried out two stripes of paper with transparent tape lapping over a few millimeters. That way I can relocate them on demand.

3: Old map
For this job I had a pretty good old map to work with. So I took with me. Colorprint on paper in a swedish style plastficka.Same scale as the base map (here 1:3500)

4: Daněks sophisticated pencil holder
Using Jiřís pencil holder for the first project, it got quickly obvious that this one is no prototype but the result of a longer development. It is fun to work with it and it definitively enhanced my drawing style and discipline enabling me to switch colors so easily.

5: Pencils and last nail
 I am drawing with a set of 0.5mm pencils (red, green, blue, lead 2H and yellow). In addition I recently added two pencils  0.7mm to the set (purple and pink) which I use for the construction. The latter are from the Pilot Color ENO series. The colors are unobtrusive and as an !!advantage!!  they fade, when exposed to light.
As what I call the last nail I also have a permanent marker with me. After erasing  the drawing film it gets glossy and the pencils  work only halfway, so after I am decided I use the last nail (Stabilo OH Pen universal red) to pronounce my final decision.
As for the color set I apply I don't have a permanent one, but I try to follow the thumb rule that the field notes should reach for maximum readability. Too dark or too light colors I try to minimze, so it is red I prefer for the most dominant features.

6: Rubber pen
I also added a rubber pen (Läufer Florett) to my set. In accordance with its name (rapier) I works fine for precise erasure.

7: Extra leads
Well. You don't want to end up  in the middle of a forest without your main colors. I did once. That is enough. I got now a tube with replacement leads for all colors as an inherent part of my pencil holder.

:-( : Compass
 Working with laser data I do not use the compass all the time. So I got it in my jacket, respectively had it in my jacket. I must have lost it in the forest. Maybe I should fix it to the pencil holder?

8: Backpack with: Food, drink & clothes


P Eglin hat gesagt…

Du verwendest kein GPS?

M.Lerjen hat gesagt…

Nicht, wenn das Gelände so feinkuppiert ist, dass die Positionierung der Objekte mittels Laser so ring geht. Bei anderen reliefärmeren Wäldern wie z.B. dem Forst habe ich das GPS zur Positionierung von Punktobjekten als "Zweitmeinung" eingesetzt.

Wie arbeitest du mit dem GPS?

P Eglin hat gesagt…

Ich verwende GPS wenn die Position auf andere Art (Laser HK, Wegnetz)nicht einfacher zu bestimmen ist.
