redesigned geotagger + different geotagging modes

[puik]

Different geotagging modes selectable from menu:

• photographer's position (selected by default)
• object
• approximate location
• aerial photograph

---

1. Photographer's position (cam-pos) geotagging (default mode):

• by default photographer's position/view sector icon is in the center of the map (as in the current Ajapaik live-solution)
• view sector is marked with dotted lines (state unspecified)
• from the position marker (probably a small circle) a image center dotted line starts that goes to the border of map
• image center line and view sector follow the mouse, on touchscreens tap fixes it (as currently)
• both icon and map are draggable: when grabbing the icon the map is not moving, when dragging the map, the position icon stays where it was, in other words: only one thing moves at a time: either map or marker >> this needs testing!
• click on the map fixes the direction of the view (azimuth), state changes: image center line becomes solid (not anymore dotted). New click on the map resets the direction (as currently), image center line state changes to dotted again.
• wild idea about view angle: the view sector outer line (fragment of circle) is draggable, when dragging it closer to the cam-pos marker, the view sector becomes wider, when dragging farer the view sector becomes narrower, releasing the sector fixes the view sector, state changes: view sector side lines become solid (not dotted anymore). Single click on the view sector outer line resets the viewsector to unspecified (dotted lines)

2. Object geotagging

Object geotagging can be separate from cam-pos geotagging, either alternative or supplementary.
User can geotag the central object (most prominent, probably the main thing that was photographed) on the image and additional objects -- objects that are also on the image, but not main subject.
Idea: user can also click on the image (photograph, painting) on the object that s/he has geotagged on the map.
What about tagging multiple images at a time? >>

3. Approximate location (approx-loc) geotagging

Can be used together with object geotagging, but not with cam-pos geotagging.

Interface idea:
A fixed size dotted line circle on the map, user can drag and zoom the map to include right area.

4. Aerial image geotagging

User has to click on at least 3 objects/places on the map and on the image for georeferencing.

Other aspects

Map zoom:

• in cam-pos geotagging mode zooms on cam-pos icon position
• in object/aerial photograph geotagging mode zoom on mouse position
• in approx-loc mode zooms on map center

Image zoom
IIIF

Image horizontal flip
As currently implemented, sends state to back-end.

Different base maps
OSM, GoogleMaps, historical maps, other WMS map services (Maa-amet)

Streetview
Toggle Streetview button that would open the Streetview in closest location to the cam-pos geotag, see example

Showing/hiding location suggestion by other users
Currently we only see the other suggestions on heatmap after the user has saved her location
