My brother is working on script to install java packages and CRP on all kind of mac...
work in progress.
At the moment the script works for Mac with silicone processors... but not on older Mac with Intel processors.

Hi Jochen,

Did you had a chance to look deeper into this?

method 3 ;)
1-set your cave data using the gps ref + surface survey + cave survey
2-right click on the cave entrance station>coordinates> write down coordinates and altitude
3-set entrance station as ref station and edit coordinates and altitude
4-disable (or delete) surface survey data.

I used extensively a pencil/tablet back in March-May 2020 and it worked nice and smooze back then.
I had a try with my new tablet (same brand - Huion - but maybe not the same model as in 2020) last October but I experienced the issue and went back to my regular mouse.
I can't figure out any actions to get rid of this issue. What is puzzling is that the pencil currently triggers 2 differents action drawing AND zoom+/- at once. Maybe something have change in the code that could explain the issue.

I have the same issue with mine (differents brand). It works as expected with other softwares so the issue seems to be with CRP.

Hi Jochen,

I have spend a bit of time testing the new polyline feature.

I think the straight parameters are too drastic for my project as it chops too many details. We worked on an old quarry (XVI-XIX centuary): Stones were cut using mining axes and the extraction management a bit chaotic, so everything is straight but nothing it straight for long.

So I get much better results using the regular spline line and then convert it to polylines (but this is not very practicle). I would go for the same point sample parameters as the spline line in this case.
This said as it is set up now, it would probably be good for drawing a modern/mechanical quarry where walls are very straight.

On a different matter (but related), I find that holding the right mouse button while drawing isn't ergonomic and my hands and arms become painfull too quiclky. Would it be possible to get something like: click to start drawing -> no click holding while drawing -> click to stop drawing?

Nice, I guess it should do the trick :)

I'm not fully convinced this would be a good feature for drawing quarry but maybe I'm wrong. Polylines is in my opinion the tool that would give the best render (straight and sharp as walls in a quarry) as well as the most practical tool as you only need to click at corner locations instead of trying to draw a straight line with a mouse.
Maybe the first step would be to fix the "issues" with polylines to make them as editable as the spline lines: i.e separate, connect, cut short end or long end. Connect would be add a straight line between the two closest end points.
And to have a dashed line option (with full or 1/2).
That would make drawing a lot easier.

Although my internet connexion is still very slow and intermittent, I don't experience any issues with CyclOSM.
Another one that I like is Thunderforest.Landscape. It does have an hillshade feature, tracks are all there, and cliffs are displayed! It doesn't have the cave entrances (but shouldn't they all be surveyed and data kept in CRP ;) )

Thanks for that,

First feedback,
- it would be nice to be able to assign depth and date a different colorscales as sometime one colorscale works well with depth but not with dates and reverse.
- Inferno is nice but one end color is too dark for black back ground and the other is too light for with back ground. Maybe keep it but reduce the color range e.g. from the graph you sent, I would remove 2 square on the dark side, and one one the light side.

Also, would it be possible to display the legend in the view. I'm often asked what the colors means... and with multiple colorscale available, it becomes even more important.

Let's give it a try with your station/radius suggestion as it might works well.
A few things though to make this tool efficent in my opinion:
- preferably, the selection tool should be graphical, i.e. after selecting the station, the selection radius should be something visible/graphical on the view: moving the mouse and clicking to the appropriate distance, instead of typing a radius value.
- multiple selections made possible to allow the selection of an aera that doesn't have a circular shape and that is intricated is the middle of other areas that you don't want on the filtered display.

aaaahhhhh for date you might be right! probably my colour blindness do me some tricks. (maybe using blue to red color scale would be best)
for surveyors, maybe adding a rule so the same color cannot be used for connected or overlapping (plan view) sessions.

not too sure of the spherical selection as it would be impossible to display exactly what you want to display. Polygonal or free-form selection would definitely be perfect or rectangle with the possibility to add several rectangle (i.e. using shift key + mouse graphical selection) but it is probably easier said than done.

tested with a new contours file and it works great!
thanks.

Hi Jochen,
sorry, I'm away from home for a while, will try first opportunity.
