Description

For detailed digitisation of archaeological and other structures it will be necessary to enable image overlays in the map.
This can be achieved by using the leaflet imageoverlay function: https://leafletjs.com/reference-1.4.0.html#imageoverlay

E.g for the plot of the Stará Kouřim cemetery. Therefore it needs a rectified image file with known bounds. This file can be added to the map by:

var imageUrl = 'plots/Kourim_north_georeferenced.png',
imageBounds = [[49.99800, 14.99246], [49.99747, 14.99328]];
L.imageOverlay(imageUrl, imageBounds).addTo(map);

Update:

  • Information is saved in web schema of database (image_id, place_id, 4 text input for bounding box)
  • Set image as overlay in place (the 'top' one) in the file tab like the profile image
  • Show overlay (default show) if at view, update or insert of this place or a subunit
  • Settings option to use overlays
  • Upload image in place/feature/stratigraphic unit/find view and define it to be a georeferenced map image along with bounding box coordinates in WGS84 (multiple ones per place possible)
  • Display these images on the respective place level per default
  • In leaflet layer control allow these maps to be toggled - name/label is the filename

#1 Updated by Alexander Watzinger 9 months ago

  • Priority changed from Immediate to Low
  • Status changed from New to Acknowledged
  • Assignee deleted (Alexander Watzinger)
  • Target version set to Wishlist

This feature will require

  • Adoptions in the backend: add new images with additional information like georeferencing
  • Adoptions to the map: a frontend developer, Christoph will start in February
  • Some conceptional work e.g. adding an extra view for basemap image manipulation. It has to be considered that, among other things, raising the zoom level will render the standard basemaps unusable.

Maybe we discuss it at the next meeting. About creating issues, especially about priority and assignee maybe take a look at: How to report an issue

Thank you for reporting with such detailed informations, it sounds like an interesting cool feature, Alex
