Durante la pianificazione di un nuovo programma Android abbiamo notato che nelle mappe e nei vari editor OSM come JOSM, Vespucci ecc. il numero di elementi supportati dalle preimpostazioni, incluse le icone, è limitato.

As a side effect I also discovered, that the selection of presets in editors like JOSM seems to have a serious influence on the number of occurrences of a certain map feature in the planet file.

But this is another topic to do some more research...
  
Inoltre abbiamo notato che l'insieme di preimpostazioni in editor come JOSM sembra avere un'importante influenza sul numero di volte che un elemento viene mappato.

I then did some research regarding the availability of icons for OSM map features and found, that currently no collection of icons with a homogenous style exists that covers at least all map features which are present in the OSM planet file at minimum 1,000 times.
  
Una successiva ricerca sulla disponibilità di icone per la mappa OSM ha mostrato che non esiste nessuna raccolta di icone con uno stile omogeneo che copra tutti gli elementi della mappa presenti almeno 1000 volte sul file planet.osm. Il miglior punto di partenza è il set completo di icone disegnate originariamente da [http://www.sjjb.co.uk/mapicons/ SJJB].
+
While researching the currently available icon sets I found, that the icons originally designed by [http://www.sjjb.co.uk/mapicons/ SJJB] would be the best starting point for creating a complete set of icons.
  
Tramite il servizio [http://taginfo.openstreetmap.org/ TAGINFO] sono state annotati quali fossero gli elementi con almeno 1000 presenze nel planet.osm e ai quali mancassero di un icona nella raccolta di  SJBB. Alle 300 icone SVG già presenti sono state aggiunte altre 700 nuove icone.
+
I then researched with the help of the wonderful [http://taginfo.openstreetmap.org/ TAGINFO service] which icons with at least 1,000 occurrences in the OSM planet file were missing in the SJBB collection and finally added to the originally 300 SJBB SVG icons more than 700 newly designed SVG icons, sometimes based on existing ideas, sometimes with completely new motives.<br>
 +
To each icon I assigned a unique 5-digit icon number which can be found on the left side of the icon file name.
  
A ciascuna icona è stato assegnato un numero di 5 cifre che può essere trovato sul lato sinistro del nome del file.

==Recommended keys and presets for each map feature==
 +
After creating a set of more than 1,000 icons in total I added to each map feature, represented by an icon, recommended key-value pairs and presets for some values. These key-value pairs were stored in the file name of the icon for easy handling.<br>
 +
The information regarding the key-value pairs was mainly retrieved from OSM wiki information, JOSM presets, taginfo findings and some other OSM related sources.
  
==Chiavi suggerite e preimpostazioni per ogni elemento della mappa==
+
While compiling the relevant keys and values for each icon I found, that some information is needed repeatedly for multiple icons. In this case I created txt files that can be found in the zip file containing commonly used key-value pairs. These txt files were then referenced in the icon file names suitable for usage of these common key-value pairs.
  
Dopo aver creato più di 1000 icone in totale, sono stati aggiunti a ciascun elemento mappabile rappresentato da un icona, una coppia di chiavi-valori e preimpostazioni suggerite. Questa coppia è conservata nel nome del file che descrive l'icona, assieme a un file di testo contenente le coppie più utilizzate,

==Feature groups==
 +
It might be pretty difficult to find the correct icon out of > 1,000 icons while mapping a certain map feature.<br>
 +
Therefore I introduced so called "feature groups". Feature groups are collections of icons / map features with a similar topic.
  
Le informazioni riguardanti la coppia chiave-valore sono state ricavate da OSM wiki, i preset di JOSM, Taginfo e altre fonti riguardanti OSM.
+
Example: woman’s fav places<br>
 
+
This feature group combines all icons / map features that might represent a POI which is particularly interesting for women: a shop with handbags, a baby hatch, a cafe etc.
==Gruppi di elementi (feature groups)==
 
  
Può risultare particolarmente complesso trovare l'icona adatta tra più di 1000 di esse: per questo motivo sono stati introdotti “gruppi di elementi (feature groups)”. Questi  gruppi sono una raccolta di icone/elementi mappabili con un argomento comune.

I created a set of feature groups and assigned icons to them. The feature groups assigned to each icon are mentioned in the file name.
  
Es. elementi legati alla donna

==Request for cross check by the Italian OSM community==
 +
Some days ago I completed the task of compiling key-value pairs and feature groups for each map feature so it is now the right time to ask interested OSM community members to cross check the work done for an optimal icon set before officially publishing it as follows:
  
Questo gruppo combina tutte le icone che potrebbero rappresentare un POI interessante per le donne: un negozio di borse, una ruota degli esposti, un cafè, ecc...

# check if important icons are missing

# check if some icons should have different graphics

# other comments
  
Nel file di testo è presente l'elenco dei gruppi di elementi.

In case you have suggestions for improving the icons, assigned key-value pairs, presets of values or feature groups, please provide this information in this wiki for discussion.

Please don´t forget to mention the icon number which is the only unique reference available for each icon.

 +
Please do NOT spread this activity around outside Italy for the time being.
  
Prima di essere pubblicato ufficialmente è richiesto il feedback alla comunità.

The zip file with all 1,000 icons as well as the txt file with the commonly used key-value pairs can be found [[here]].<br>
 
+
Please explode the zip file in the root directory of your hard drive. Otherwise it might fail because of the length of some of the file names.
Viene richiesto:
 
 
 
# di controllare se mancano icone importanti
 
# di segnalare se alcune icone necessitino di essere ridisegnate
 
# di controllare se le coppie chiavi/valori sono ottimali
 
# di controllare se i gruppi sono ottimali
 
# di esprimere commenti o suggerimenti nella sezione Discussione.
 
 
 
 
Ricordatevi di indicare il numero dell'icona nei vostri commenti!
 
 
Per ora la discussione è limitata alla comunità italiana per evitare un numero troppo elevato di commenti da tutto il mondo. Dopo questa prima fase di controllo, la discussione verrà spostata a livello internazionale, coinvolgendo le comunità più grandi (tedesche, inglesi, francesi...).
 
 
 
In base al risultato della prima fase, tra qualche settimana potrei chiedere una partecipazione più ampia da parte della comunità.
 
 
 
Per favore NON diffondete questa attività al di fuori della comunità italiana per il momento.
 
 
 
Il file zip contenente le 1,000 icone e il file di testo può essere scaricato [[Media:OSM-icons.zip|qui]].<br>
 
 
 
NOTA BENE: a causa del nome lungo di alcune icone, è necessario estrarre le icone in una cartella all'interno del livello più basso del vostro hard disk (es. c:\Icone) altrimenti potreste incontrare alcuni errori durante lo scompattamento.

Aiming to compile a complete set of OSM POI icons

During the planning of a new Android software I discovered that on the various maps as well as in various OSM editors like JOSM, Vespucci etc. the number of map features supported by presets including the available icons is limited.

As a side effect I also discovered, that the selection of presets in editors like JOSM seems to have a serious influence on the number of occurrences of a certain map feature in the planet file. But this is another topic to do some more research...

I then did some research regarding the availability of icons for OSM map features and found, that currently no collection of icons with a homogenous style exists that covers at least all map features which are present in the OSM planet file at minimum 1,000 times.

While researching the currently available icon sets I found, that the icons originally designed by SJJB would be the best starting point for creating a complete set of icons.

I then researched with the help of the wonderful TAGINFO service which icons with at least 1,000 occurrences in the OSM planet file were missing in the SJBB collection and finally added to the originally 300 SJBB SVG icons more than 700 newly designed SVG icons, sometimes based on existing ideas, sometimes with completely new motives.
To each icon I assigned a unique 5-digit icon number which can be found on the left side of the icon file name.

Recommended keys and presets for each map feature

After creating a set of more than 1,000 icons in total I added to each map feature, represented by an icon, recommended key-value pairs and presets for some values. These key-value pairs were stored in the file name of the icon for easy handling.
The information regarding the key-value pairs was mainly retrieved from OSM wiki information, JOSM presets, taginfo findings and some other OSM related sources.

While compiling the relevant keys and values for each icon I found, that some information is needed repeatedly for multiple icons. In this case I created txt files that can be found in the zip file containing commonly used key-value pairs. These txt files were then referenced in the icon file names suitable for usage of these common key-value pairs.

Feature groups

It might be pretty difficult to find the correct icon out of > 1,000 icons while mapping a certain map feature.
Therefore I introduced so called "feature groups". Feature groups are collections of icons / map features with a similar topic.

Example: woman’s fav places
This feature group combines all icons / map features that might represent a POI which is particularly interesting for women: a shop with handbags, a baby hatch, a cafe etc.

I created a set of feature groups and assigned icons to them. The feature groups assigned to each icon are mentioned in the file name.

Request for cross check by the Italian OSM community

Some days ago I completed the task of compiling key-value pairs and feature groups for each map feature so it is now the right time to ask interested OSM community members to cross check the work done for an optimal icon set before officially publishing it as follows:

  1. check if important icons are missing
  2. check if some icons should have different graphics
  3. check if the selected key-value pairs are optimal
  4. check if the feature group assignment is optimal
  5. other comments

In case you have suggestions for improving the icons, assigned key-value pairs, presets of values or feature groups, please provide this information in this wiki for discussion. Please don´t forget to mention the icon number which is the only unique reference available for each icon.

It is intended for now to limit the discussion to the Italian community for not getting flooded with comments from all over the world.
Depending on the outcome of this 1st step I might in a few weeks then ask a bigger part of the community for participation.
Please do NOT spread this activity around outside Italy for the time being.

The zip file with all 1,000 icons as well as the txt file with the commonly used key-value pairs can be found here.
Please explode the zip file in the root directory of your hard drive. Otherwise it might fail because of the length of some of the file names.
