Passopass project map HELP page

This is the interactive map for the PassoPass project. The goal is to visually render the project's area of interest, showing its points of interest and natural, rural and cultural items, alpine alms, shelters, bivouacs and finally the trail network.

Legenda
• Generic point of interest
• Alpine alm, with cows! Sometimes they also feed hikers
• Alpine alm & accomodation. There still are cows but also various services and accomodation for hikers and tourists, nice!
• Alpine hut, with services and beds, maybe seasonally open
• Wilderness hut, maybe an old and unused alpine alm or some kind of shelter, unattended, always open, usually have a fireplace
• Bivouac, the classical one, just a place to sleep, no fireplace, no benefits
• Numbered trail, with signs and painted waymarks, almost always RED-WHITE-RED, these are Alpine Club official trails

Moving around
• Zoom: use mouse wheel, double click, pinch to zoom on touch devices or [+] [-] buttons of the top left menu
• Pan: use click & hold + mouse move, swipe gesture on touch or keyboard arrows to pan the map

Utilities
• Fullscreen: either F11 on the browser or click the menu item in the top left for fullscreen, press again to toggle fullscreen or use ESC key, on most mobile phones a swipe from the top of the screen should also exit fullscreen mode
• Enable Location: Use it to enable a pinpoint on the map that shows you real-time location and pans the map there, you need to give right permissions to the browser to get your current location. (Note: location info lives only on your own device for your use, nothing about your location is moved online, all the map once loaded lives only on your device/s)
• Language selector: here you can choose the interface language, map items will show the information in the chosen language, current language is highlighted in green and shown on the top right part of the screen

Layers
• Map base layers: from the top right menu you can choose which kind of base layer the map should show.
  The default layer is "UTI Topomap" a very well done rendering made by the SIT office of the UTI della Carnia in Tolmezzo.
  The others are classic mapnik Openstreetmap, Opentopomap, an Openstreetmap rendering good for outdoor use and two ESRI free layers one light topographic rendering and one from satellite
• Map overlays: from the top right menu, bottom part, you can choose which layers should open over the base layers, these are the interactive layers who can have a tooltip, open a popup or trigger a more descriptive panel on the left most side of the window.
  Most of these layers are dynamic with zoom levels, revealing all or only some of the information, this to avoid clutter on the map.
  Mouseover action on these layers reveals names, click action reveal popups or left side panels.
• Elevation graph: mouseover on a trail line shows the name of the path itself, a single click triggers an interactive elevation graph that can be used to "walk" the chosen trail and have information about it like
  • elevation
  • max elevation
  • min elevation
  and on mouseover the graph shows live info about the points of the trail like
  • point elevation
  • length (plain) from the start to the point
  • estimated walking time from the start to the point
  This last info is calculated live step by step from the length and elevation gain of every single trail segment and summed while walking over it, the algorithm assumes a pace of 3.5km/h on plain terrain and works pretty well on hiking trails without extremes in steepness or on extreme slopes like "via ferrata" where this info is simply hard to have and meaningless, but for the great majority of the paths it works and gives an estimate time that one could adapt later to his/her own personal walking pace. Note: elevation information is taken from digital terrain models like SRMT or FVG Region 1 meter DEM, the last is extremely accurate, so elevation information is "just right" full stop.

Clean view / reset map
• Clean view: a single click on the base map in an empty area, without points, lines or labels, works as a soft reset for the popups or left side panels closing them, it also resets and delete an active elevation graph
• Hard reset: if for any reason the map is broken an hard reset is possible by reloading the page pressing F5 or forcing reload it with CTRL+SHIFT+r on PC
