The mirror keywords are occasions when the same object exists on both sides of the reference object. In our case, the object is a ditch and the reference object is a path.

  • both, a generic notion that the object exists on both sides
  • ceil, $⌈x⌉$, the object is on both sides and has a $⌉x⌈$ shape
  • floor, $⌋x⌊$, the object is on both sides and has a $⌊x⌋$ shape

Typical examples where ceil|floor occur is when a highway yields (perpendicularly) into another highway or an intersection of two highways.

It was already introduced the cardinal directions for general positioning, though often these don’t suffice when dealing with ditch positioning.

Thus three mirrored keywords are introduced: both, ceil, floor and three positional keywords: left, right, reverse|rev|- plus a wide range of shapes: L,V, T, Y, [, ].

To simplify such crossings the following keywords are added for note taking:

  • culvert|c
  • bridge <material>, the material is added if it differs from the highway
  • ford

For example, if a new path exist with a culvert than the note says other pc or other p c. Or on an existing highway one would just add other c.

There are (in general) three possible ditch crossings:

  • tunnel=culvert, layer=-1 for the ditch
  • bridge=yes, layer=1 for the highway
  • ford=yes for the intersection between ditch and highway.

One of my areas is waterway=ditch mapping. In this realm one mainly needs to know the possible crossings, the water flow direction, and on which side of the highway it exists.

The flow direction is the trickiest of the three, since with the tag intermittent=yes one cannot depict directly the flow direction. The tag is used when the ditch is either dry or has little water across the year. This tag is optional, though since it exists, expect the outcome to meet such instances in the wild.

Thus eventually instead of using the generic note for a random topic, it was agreed upon that it denotes a path.

Though lately removed the ambiguous definition and hard defined the word path|p. This removes any potential guess work in the future.

A simple example of a perpendicular path is other p where as a more complex one could look like other p sw which equates to a path that is going south west away from current highway.

One thing that I have done in the past is have a topic per hike. This means I have a generic note that just says other . This is then connect to a quick action.

So if the topic e.g. are bird perches, then each of them will just be denoted with “other “.

This is all good for maybe up to a couple of days, though if notes first get resolved weeks in the future, then that detail is lost, thus the effort is gone.

While on the topic of barriers, these typically have a start and end. One could attempt to use the starting letter of start and one would realize that s has already been declared for south. Likewise doing for end, one gets e which is used for east.

For this conundrum one can look at the Greek alphabet and use the first and last letter. They are alpha and omega making it a and o.

Example of a railing south of the path. The start of railing: railing s a and respectively for the end: railing s o.

Another typical example are railings or fences along a path. Since one barely ever knows which direction the way is going, thus a safer approach is to use the cardinal directions to denote a one-sided barrier.

Caveats are more obvious cases like steps, where usually incline=up aligns with the way’s direction. In this case left|l and respectively right|r are used.

The first shorthand note are the cardinal directions denoted as n, e, s, and w.

These can be combined together to create more concrete directions like ne, se, sw, or nw. Or even more specific nne, een, ees, sse, ssw, wws, wwn, nnw.

An use-case is to denote more specifically where an object should be positioned relative to a way or an area. So if e.g. a path does not exist yet which branches off the current path and it is not perpendicular to the current path, then these directions can help to map the initial path head.

Hint: make sure to add the fixme key at the path’s tail to check if the path continues. The most simplest value is continue?.

In the past, I already wrote a blog on how to create quick actions in : bf5.eu/post/osm/how-to-quick-m and for the next couple of entries regarding shorthand note system (that I use), the notes are created in such a way that a quick action cannot replace it.

That being said, kind of wish OsmAnd had quick action presets, so that one can quickly ease the sorting of the quick actions when in various situations. Like in urban terrain fire hydrants and street cabinets are more frequent, where as in comparison in rural terrain the frequency of hunting stands and feeding places are higher.

In the past, I uploaded the notes to the server and have (an outdated) note interpreter for my shorthand notes: openstreetmap.org/user/barefoo

Though these days, I only push notes if they are obvious and/or I am using a specific app that does not permit offline notes. Like being a bit too fast with floors or type of building in , though the new buildings overlay should take care of this issue in the past.

Onto the in person mappers comes the goal factor. This means is the goal just to map or is the goal to get to a specific destination.

If it’s the latter then one needs to manage between achieving the goal while mapping on the fly. For such cases there are many apps that can achieve the updater aspect without losing too much time mapping. To name a few or .

In the manager aspect the mentioned apps can help or or or .

Though many times one doesn’t have enough time to navigate through the apps to accomplish the desired outcome. Thus jotting a note down or taking a photo can quickly save the details and later when more allotted time exists they can be updated.

One is usually a combination of the three kinds of mappers: creators, updaters, and managers.

Typically, one starts as an updater. Then once one is comfortable of knowing which objects exist, one adds creator to the mix. And finally once even more confident of the correct data format, one adds manager.

When doing in person, there are typically three kinds of mappers: creators, updaters, and managers.

A creator is a mapper who creates new objects. Predominantly by adding amenities like POIs or more specifically: benches, waste bins, fire hydrants, street cabinets, etc.

An updater is a mapper who updates existing objects by adding missing data to complete the object. Most of quests fall into this category.

A manager is a mapper who edits existing objects. This means that at least one key-value pair is incorrect. A typical example is that the opening hours are outdated. Other cases are updating highway or other line based objects like waterways, or updating land covers.

Got to try out the new building overlay feature on . It quickens the choosing of the building values and eases the option of updating them as well.

IMO, the icons of the buildings feel a bit small and could use the white space better.

One issue that I have experienced with the mirroring is that the repositories were not syncing up. Tried resolving it with refreshing tokens/keys and playing around with the configs.

In the end, the easier option is just to manually push to a different remote repository.

There are plenty of options to choose from when mirroring and one that makes sense is to only mirror the main branch after a successful pull request. This reduces resources and access to broken code.

Additionally, only builds off of the main branch, so there is really no need to have a duplicate of all other branches.

An alternative option is repository piggy-backing. The means take one of the permitted repositories and mirror one’s own repository to it.

A nice side effect of this is that the code is now at two locations.

One downside of using is that it does not integrate directly with .

vercel.com/docs/deployments/gi

Thus there exists the Vercel CLI tool.
