Occurrence Map Zoom to Data-extents and MapSettings

[jloomisVCE]

@MortenHofft As I am configuring a test site for MVA using the data-widget, I am wondering if there is a good way to implement zoom-to-data and zoom-to-map-settings features. In Leaflet maps, I have done this with a button or a link. Does this make sense to add somehow?

In a browser with cache, the map nicely retains the user's last zoom. I haven't found an easy way to return to the initial view defined in the mapSettings configuration value, or to the data displayed on the map.

Thanks for considering this.

I'm not sure I understand:

• Do you mean an easier way to configure the default map view (the map settings)
  • You are completely right, it is a bit tricky. you need to know the latitude and longitude and guess the zoom level. Or like I do, zoom to the extent I like and look in the localStorage where it is stored. But neither is very user friendly.
• Or A button on the map that takes you back to the view defined in code?
  • We can add that, but I'm not sure I find it necessary. Personally I find that the zoom and pan with the mouse is so fast that it isn't an issue should I have dived into something

UPDATE: Or do you mean a button to zoom to the points that are displayed for a specific query? E.g. I look at the table, add some filter, then go to the map, but the maps do not show anything in that extent, because it wasn't where i was last time.

Thanks. Yes, I mean both of those last two: 'zoom to map settings' and 'zoom to displayed points'. Of those two, 'zoom to displayed data' is MUCH more valuable.

PS: on the first one, 2 years ago I got sick of searching for an app to find my lat/lon/zoom on a map, so I added it to our vernal pool atlas. I have noticed that mature mapping applications, like ESRI, have map navigation features for super-users to 'zoom to point', etc. We have some GIS specialists who asked me to add features.
