Leaflet map config - minimum requirements.

[jeffs...@exemail.com.au]

I'm running RS svn trunk version r27715.

I found some helpful conversations regards the Leaflet maps topic dating back, it seems, to 2022 and its inception in Resourcespace version 9.6.

As far as I can tell, the Esri maps I configured (World Street Map as default) is working fine, but I'd just like some clarification on the config.php settings discussed in the Knowledge Base |  Configuring Leaflet Maps topic.

In particular there are two main areas to investigate when applying the config.php setting $geo_leaflet_maps_sources = true;

1. ../include/map_basemaps.php contains the necessary variables that should be 'used to enable a specific basemap group.

2. ../lib/leaflet_plugins/leaflet-providers-1.10.2/leaflet-providers.js contains the access information, i.e. map URL and options as well as variant information for the different views.

The KB article also provides information for populating an array variable called  $geo_leaflet_maps_sources[]. It implies that it is a transform of the same data found in leaflet-providers.js.

My first question relates to the need to populate this variable when the data it contains is already available in the aforementioned  leaflet-providers.js file.

For example, if I provide the following config.php entries, then I am able to access the maps OK.

## Enable Leaflet Maps.

$geo_leaflet_maps_sources = true;

## Set the default using Code.Variant as per leaflet-providers.js.

$map_default = 'Esri.WorldStreetMap';

## ESRI Maps enable from map_basemaps.php
$map_esristreet = true;
$map_esritopo = true;

$map_esriimagery = true;

Of course caching, zoom, default bounds etc etc are also needed for a complete config, but above is all that appears to be required to access the relevant mapping provider. Can I therefore assume that the  $geo_leaflet_maps_sources[]  example provided for USGSTNM is to act more as a template in the cases where the mapping provider is NOT available in leaflet-providers.js?

My second question is aimed at when  map_basemaps.php doesn't contain the necessary variables for a mapping provider contained in  leaflet-providers.js.

An example of this is HikeBike. What 'enabling' variables need to be set to True in this and other similar cases? Is it intended that map_basemaps.php be modified ... which would break the default SVN pull. How is it meant to be handled?

Thanks, Jeff.
