Last week the new and long awaited hiking map of the "Sentieri CAI dei Monti Lattari:Penisola Sorrentina, Costiera Amalfitana e Isola di Capri", (the CAI trails of the Monti Lattari: Sorrento Peninsula, Amalfi
Coast and island of Capri”) was presented. It has been produced by three
branches of the Italian Alpine Club (CAI), Castellammare di Stabia, Cava dei
Tirreni and Naples, in collaboration with the
Consorzio Turistico Amalfi di Qualità and has already generated considerable
feedback.
Probably the most comprehensive and detailed has come
from Giovanni Visetti who, as anyone interested in hiking in this area will
know, is an expert cartographer and particularly clued up about our local
trails. I will now do my best to give a succinct résumé of his blog on this
subject.
He is complimentary
about the overall graphics, the print, the quality of the paper and above all
the impagination. The map extends front and back, but with a wide range of
overlap, so that it will only be necessary to consult both sides if the walk is
particularly long. If the old map on a 1:30.000 scale was enormous and
unpractical, precisely because of its dimensions, the new map with its even
larger scale (1:25.000) would have been virtually unusable during a hike if
printed on just one page.
Due to the physical
characteristics of the Monti Lattari it might have
been even more useful to increase the scale yet further to 1:20.000 so that the morphology of the territory could
be better described with the inclusion of more of its infinite trails, passages
and steps, so characteristic of the coast.
For Giovanni (and not just him, since this has been
highlighted by others too) this is the map’s weakness and there are various
reasons why. Some are absolute limits, since with such a scale it is impossible
to represent everything. If the lines were made narrower and the dimensions of
the symbols reduced in order to include everything, the map would become
illegible submerged in details. Another
problem is the classification of the many extra-urban paths (those that
are of greatest interest to the hiker) in such a way that their difficulty and
ease of identification is clear to the map-reader. Anyone who has walked the CAI trails
of the Monti Lattari knows that many of these paths are
rough but easy to identify (no other options being plausible), whilst others
are easy to walk but difficult to follow, passing through woods or open fields
with little gradient and very few points of reference and where, in spring and
summer, the vegetation invades those lesser frequented, hiding their eventual
way-marks at ground level.
This map has been produced by the CAI and therefore,
and quite rightly from their point of view, the highest possible profile has
been given to their own identified and marked trails. However Giovanni thinks
that for future editions, (and even earlier online), it would be appropriate to
integrate these with at least the other main paths used by local hikers and
tourists, since as being very evident, they are important both as a point of
reference and as potential escape or access routes. To give an example, the
path Praiano - San
Domenico -Cannati (Path of the Gods) is missing from the
CAI map. This is a path regularly used by hikers and above all by foreigners
staying around Positano, Vettica and Praiano, who can, by taking this route,
avoid having to take the bus first to Amalfi and then to Bomerano to reach the
Path of the Gods and not only.
The work on this map has been in course for several
years and therefore it is understandable that the authors wanted to start
producing something tangible, even if, at the same time, they have publicly
declared that, although satisfied with the result so far, the map still needs
numerous adjustments and that therefore work is ongoing. This is true of any
map or tourist guide, since months if not years pass between the surveying and
the printing , plus it is impossible to control hundreds of kilometres of
trails and thousands of roads, streets and lanes constantly. It therefore goes
without saying that no one can ever claim that a map is completely up to date.
In view of this it is essential that this map is updated whenever possible, without waiting for a general revision
some time in the future. Cartography is always work in process, as Giovanni
points out, citing as example his own newly updated map of Massa Lubrense and
Sorrento (first published over 25 years ago) in order to mark various
interruptions and insert Vuallariello and Acquacarbone, historical trails
closed for years but now cleared and
open for hikers.
The project coordinators have had the foresight not to
use a cartographic base such as I.G.M. which, although of excellent quality,
would always have remained the property of that entity, preferring to take the
long, complicated and onerous way of drawing the map from scratch so that it
remains their exclusive property.
Even if the results are far from perfect (a map can
never be perfect by definition) in future they will be able to update it
digitally, practically in real time and at no cost.
However, the real
innovation has been the genial idea to create a new website www.caimontilattari.it where the map is freely available.
Here you can consult the individual routes complete with their itineraries,
altitude profiles and GPS tracks. The search for the paths is very simple. You
just need to type a single word in the appropriate window, (eg the number or
name of the path or even the departure
or arrival point).
The new map is excellent for planning
a hike since it gives a general vision of the territory, with all the CAI
trails evident. It will therefore be easy to plan itineraries which include
more than one path, choose and evaluate the time and distance, all simple
operations if you use the information on the site including the altitude
profiles.
That said, the detail is still very lacking
and more work needs to be carried out as soon as possible to make the GPS
tracks congruent with the contour lines and the actual paths or roads. As Giovanni wrote in one of his previous blogs, it
is practically impossible for a gps track, no matter how accurate, to coincide
precisely with the altitude profile due to the contour lines. The designer
(with the help of the surveyor or at least someone who knows the route well)
will have to adapt the contour lines to the gps tracks or vice versa, otherwise
the details will be inaccurate.
Here Giovanni uses as an example the route to the
Molare which seems to have shifted north. In the image you can clearly see
that, although the route of the path is substantially correct, the way in which
it has been superimposed onto the map induces the hiker to look for a slope on
the northern side (impossible for a non climber), taking him away from the
existing path on the southern side.
Although, as someone pointed out, hardly
anyone actually uses a map, sometimes because they don’t know how to, but
mainly due to the bad habit of keeping it neatly folded in its cover inside the
backpack, bad habits and limitations are not a valid reason
for sacrificing accuracy for approximation. Giovanni has always suggested taking a photocopy of your specific itinerary with you, rather than the whole map, and now that this can be printed or even saved onto your smartphone or tablet, there is no reason not to.
To sum up
· the overall work which covers
the entire network of about 500km of the trails marked by the Stabia and Cava
CAI on the Lattari Mountains is to be appreciated;
· it is a clear basic map,
particularly with regard to the morphology of the area which has been
highlighted not only with contour lines (no small job) but also by a good use
of shading;
· the minor roads and non CAI paths
have been a little overlooked, both in quantity and representation, but this
can easily be remedied, though of course, it will take time;
· there are too many points
inserted in the middle of nowhere, not linked to clear elements, and therefore vague and of no use,
whilst other significant elements such as
peaks, saddles, intersections and easily identifiable points such as the
ends of the paths are insufficient;
· the various symbols are too big,
such as the invasive and ever-present little flags numbering the paths and the
symbols of the snow holes (luckily very few), the caves and the climbing sites.
With regard to the latter two, the paths linking them to the CAI trails should
be added, but the most serious consequence is that because of the size and quantity
of these symbols, they often cover other more significant details of the map
(why waste time marking important details and then cover them with an icon?);
· to have the updated trail
numbers and a representation of the routes existing today is a great step
forward. Many have been added whilst some of the old ones have been abandoned;
· without a shadow of doubt it is
the only valid general map of the Monti Lattari, much more legible than the
previous CAI map, which although it had a more detailed base (IGM tables) had
become obsolete and many of the superimposed red lines (representing the paths)
differed by several hundred metres and over 100 meters of quota difference to
reality. Even if the GPS tracks do not entirely match the trails in the new
map, the discrepancies are restricted to a few tens of metres;
· there is no point in comparing
it to the map produced by the Parco dei Lattari which
is absolutely impracticable.
· other maps (such as Kompass) are on too small
scale, insufficient, totally inaccurate and inadequate for hiking in such a
varied and rugged landscape packed with
trails, as the Sorrento-Amalfi peninsula
· the new website
www.caimontilattari.it, in Italian and English, is excellent, and not only has
no equal in this area, but is truly innovative and easy to navigate. The CAI
map superimposes the Google map and you can select which levels to consult. On
each path tab at the bottom of the map you have the elevation profile and you
can download the GPS track, which can be used in combination with the map! This
too can be downloaded with the full itinerary, quotas, gradients, length, times
and difficulties.
Giovanni concludes his lengthy dissertation with the following words:
All in all an onerous
and meritorious achievement if it is to be considered a starting point. Hopefully work will continue. Whatever, the promoters, surveyors and collaborators
deserve a round of applause and a big thank you.
