Coloring on a altitude basis
by Marco Menchise 28 Sep '15

28 Sep '15

Hello, I searched in the archives and I didn't find an answer. I like to make plan and extended sections colored by altitude because this is a way to add a "3rd dimension" to a plan drawing. I also like to have the same color in the same cave region either in plan and extended section. This way makes very easy to identify same portions of a cave in both projections. Because Therion colors on scrap basis, I'm forced to draw plan and extended section using the same scrap subdivision. This is a very complex operation and it's not always simple to have the same scrap structure in both projections. Is there a way or a trick to color by altitude, maybe defining an "altitude step" to change colors? Thanks, Marco

GPS app for android
by Rob Countess 27 Sep '15

27 Sep '15

So I ended up with a Samsung galaxy S5 Active. Can anyone recommend a good app for android that does GPS averaging to get accurate fixes on cave entrances? Other good GPS apps useful for cave stuff? I thought i saw something on this listserv but my searched came up empty. I'm looking forward to testing out my set up. Thanks, Rob

I have an S5 (not active) as well. Have been using Backcountry Navigator too gps pro on the recommendation of a friend. About $15 I think and there is a free version.Maybe not as comprehensive as what Martin suggested. I am new to devices like S5 and to gps software and it took me quite a while to figure it out and make it useful.Am using it intensively while travelling with a view to using it for caving eventually.Offline maps are good but limitation of 4GB per map folder for maps that can be 'managed' is a pain. (It can handle unlimited map sizes but ability to manage an move them on and off device is not available with those storage methods).GPS is I think quite good . Often claims 3m although repeated fixes over multiple days give way points and trails within a 10mm to 20m band. Has a few annoying characteristics but the author is responsive and fixes things that break with updates. I am invested in many gb of data and time so not keen on changing but would if someone can confirm other package is much better for cave mapping and prospecting.Bruce Sent from my Samsung device -------- Original message -------- From: Rob Countess <rob.countess(a)gmail.com> Date: 27/09/2015 03:00 (GMT+05:45) To: List for Therion users <therion(a)speleo.sk> Subject: [Therion] GPS app for android So I ended up with a Samsung galaxy S5 Active.

metapost help - line Blocks
by Andrew Atkinson 23 Sep '15

23 Sep '15

I think this started life at the AUT line symbol for Blocks. My metapost is at the stage where I can just about edit it to get small changesm but that is about it. With the AUT symbol you got blocks at funny angle when going round a tight curve, I think this was because it took it angle from the start of the place that it was drawing the block, so I added the st variable as well as reducing the randomness of the angle. I also increased the length of the blocks, plus added an extra point on the block and added a bit of space between. All well and good, but now occasionally, probably about 1/4 of the time, the last block in a line is drawn on top of the second last block in a line then a space the size of the last bock is left. No idea why this should be controlled by position t which is the same as the rest of the blocks that work fine. If anyone could help solve this I would be most greatful, trying to print the survey for HE in 5 days time, so printing needs to be sent off asap thanks Andrew def l_wall_blocks_CHED (expr P) = T:=identity; pickup PenC; laenge := arclength P; path block; path old_block; cur := 0; #draw first block old_block := punked (( (.65u,-.15u)--(.72u,0.05u)--(.55u,.15u)--(.23u,.17u)--(.0u,.03u)--(.05u,-.1u))randomized (0.1u)) scaled (uniformdeviate(0.3)+.65); block_width := (xpart urcorner old_block - xpart ulcorner old_block); t:= arctime (cur+block_width/2) of P; old_block:=old_block rotated angle( direction t of P) shifted point 0 of P; thclean (old_block--cycle); thdraw old_block; cur := cur + block_width + 0.04u; forever: # generate random block block := punked ( ((.65u,-.15u)--(.72u,0.05u)--(.55u,.15u)--(.2u,.17u)--(.0u,.03u)--(.05u,-.1u) ) randomized (0.1u) ) scaled (uniformdeviate(0.3)+.65) rotated (uniformdeviate(20)-10); # check width of block block_width := (xpart urcorner block - xpart ulcorner block); exitif cur > (laenge- 3*block_width/2); # find next position where the block fits in without intersecting the previous one forever: exitif xpart ( ((block--cycle) rotated angle(direction t of P) shifted point t of P) intersectiontimes old_block) < 0; cur:=cur+0.01u; t:= arctime cur of P; st:= arctime (cur+block_width/2) of P; exitif cur > (laenge- 3*block_width/2); endfor; exitif cur > (laenge- 3*block_width/2); old_block:= block rotated angle(direction st of P) shifted point t of P; thclean (old_block--cycle); thdraw old_block; cur := cur + block_width + 0.04u; endfor; # generate last block block := (((.65u,-.15u)--(.72u,0.05u)--(.55u,.15u)--(.2u,.17u)--(.0u,.03u)--(.05u,-.1u)) ); block_width := (xpart urcorner block - xpart ulcorner block); # scale last block to fit in the remaining gap scale_factor:=(laenge-cur)/block_width; t:= arctime cur of P; st:= arctime (laenge+cur)/2 of P; forever: exitif scale_factor < 0; exitif xpart ( ( (block) rotated angle (direction st of P) scaled scale_factor shifted (point t of P) ) intersectiontimes old_block) < 0; scale_factor:=scale_factor-0.001; endfor; if scale_factor > 0: thclean (block--cycle) rotated angle (direction st of P) scaled scale_factor shifted (point t of P); thdraw (block) rotated angle (direction st of P) scaled scale_factor shifted (point t of P); fi; enddef; initsymbol ("l_wall_blocks_CHED");

osx mavericks - loch 3D overlay graphics
by Dr. Heinrich Kestler 22 Sep '15

22 Sep '15

I managed to install thereon successfully on osx mavericks using home-brew. Nearly everything seems to work fine so far. However, trying to apply an overlay graphic to a surface model in loch, it doesn´t work, i.e. the surface remains grey. I wonder whether this is a known issue with loch or if I missed to install something. Any suggestions? Many thanks in advance! Heinrich

Turning some labels on and off
by Andrew Atkinson 19 Sep '15

19 Sep '15

Hi all Over the years there have been many discussions about how to turn some but not all labels off, for things like different scales. Lots of metapost that sort of solves some problems, so I was about to right some code for my situation http://wotcc.org.uk/__Transfer/Reads.pdf (work in progress) For this I need to have some labels only on the combined view, some on the exploded view and some on both. I was going to aim at using -attr print comb or -attr print explo and then use metacode to decide where they should be visible. Ideally I would just be able to set an attr and then use symbol-hide attr print:comb but no luck there, unless I messed something, In the end metacode was not needed, I just chose 2 symbols I do not use and added them as a -context point raft and context point clay then symbol-hide point clay or symbol-hide point raft Bit of a bodge, it would be better if attr could be used, but I think that this could be used for lots of the problems I found on the mailing list while looking for a more elegant solution Andrew

Arranging legends
by Andrew Atkinson 15 Sep '15

15 Sep '15

Guess you all can tell I am trying to get a survey complete by the number of emails I am sending For anyone who is interested in what I am doing, the pdf if available at http://wotcc.org.uk/__Transfer/Reads.pdf and the raw data at http://www.cave-registry.org.uk/svn/Burrington/Reads/ I am using the legend command to put text in different places and other pdfs to make up a complex final poster. Some thoughts/observations When using the normal map header 0 0 nw legend on/off works and turns the list of symbols on and off colour-legend thbook says colo[u]r-legend <on/off> ◃ turn on/off legend of map-fg colours when map-fg is set to altitude, scrap or map (M, A) but the map colours seem to remain in the legend? As soon as you use code tex-map \def\maplayout{ \legendbox{ } map-header and map-image get ignored, which is a bit of a pain, as everything has to then go through the \legendbox. My guess is there is a reason for this, but it would be better if the 2 map commands could still be used. I cannot find a way to insert the list of symbols \legendbox{110}{-200}{NW}{\the\legendcontent} Put the legend on with the scale bar, north arrow ..... map colours, but no list of symbols using legend on/all/off seems to make no difference. This is the one I could really do with a solution to, as I would like to have the list of symbols As \formattedlegend adds in the map colours, my feeling is that \insertlegend should put it in but have not got anywhere with \legendbox{150}{-230}{NW}{\iflegend\the\insertlegend\fi} \legendbox{150}{-230}{NW}{\iflegend\insertlegend\fi} \legendbox{150}{-230}{NW}{\insertlegend\} \legendbox{150}{-230}{NW}{\the\insertlegend} thanks in advance Andrew
