            I also can't get it to do the IOS, not even with the INCLUDE (which becomes supported by GiST in v12).

            However it looks to me like all the time is going on the CPU in checking your geometry column against your monster geojson, which I think still has to be done even if you were able to get an index-only scan. So even if you could get it to use an index-only scan, it might not actually help you.

            A Mercator is usually clipped at roughly 85 degrees North/South (~85.05113 N/S) - as further than this you get a map that is taller than it is wide, and one that gets much much taller for every extra degree north/south included in the extent..

            D3 clips features using this limit:

            The spherical Mercator projection. Defines a default projection.clipExtent such that the world is projected to a square, clipped to approximately ±85° latitude.

            The northern bounds are fine, but the southern bounds of the geojson is -89.998926 degrees which you use to cut the image. But as D3 clips the geojson, your stretching the image by a different amount as compared with the geojson, hence the issue you see.

            The solution should be to clip the image to a bounds that is representative of the limits of what D3 will render for a Mercator (85.05113 degrees south) not the limits of the data itself.

            I haven't looked up how faithfully gdal implements EPSG:3395 as the definition provides for a projected bounds of 80 degrees south and 84 degrees north - though looking at the image, this doesn't appear to be an issue.

            You can also use the cleaner fitSize methods for D3 projections (d3v4+):

            I'll try to do my best to explain everything here the best I can, I copied a bunch of the code from Ray's website so I don't understand everything 100%. That being said, the main meat of what needs to be done is to layout the coordinates for the overlay. This was done in a custom class. The idea here is to parse coordinate data which was written in a plist in a Dictionary. For my project this was easy because I simply had to set the maximum coordinates for the Earth ((90, 180), (90, -180), (-90, -180), (-90, 180)). The mid coordinate only worked when I set it as (100, 0), not sure why, but the full code for parsing the plist is below.

            Ok, I found a solution if anyone else will ever need it.

            1. I added a UITapGestureRecognizer to my map view instance.
            2. I used the MKMapView's convert(_:toCoordinateFrom:) to convert the touch point to the map coordinates
            3. I created a MKMapPoint from that coordinate and checked if the MKPolygon renderer path contains the point
            4. For the MKPolygon, being a MKShape after all, I used the .title property to assign my zone_id value parsed from the GeoJSON.

            So I was able to identify which polygon was tapped.

            Clusters not appearing in leaflet from Marker Cluster and FeatureGroup.SubGroup
            Asked 2022-Feb-25 at 08:49

            I've been incorporating the MarketCluster and the associated FeatureGroup.SubGroup plug ins from Leaflet to add additional functionality to my generated QGIS2web map.

            Part of my requirements is toggleable layers and where MarkerCluster works well when I had categorized layers from QGIS that were automatically clustered with separate layers this is no longer the case. To my understanding I needed either MarkerCluster.LayerSupport or FeatureGroup.SubGroup plugins to handle the additional layers and still provide clustering.

            I've incorporated the CSS from MarkerCluster, JS from MarkerCluster and SubGroup, as well as called it in the map and in the respective places but the icons aren't actually clustering - image below.

            The bottom 3 layers are all under the parent group mcg and all have been added to the map and called under the plugin so I'm not too sure why they are not clustering at small scales?

            How to extend Leaflet Icon Class to add data-open attribute to marker HTML?
            Asked 2022-Feb-09 at 19:57

            I'm trying to trigger some functionality based on the click of a marker on a GeoJSON layer in Leaflet. The eventual functionality I'm trying to implement is a flyout, or scroll out type modal populated from the individual feature's JSON attributes. Essentially, I'm trying to implement the functionality in this Tutsplus Tutorial with dynamic feature content based on the marker click.

            I THINK I've figured out most of the pieces I need, but I'm struggling with how to add a data attribute, specifically data-open, to the individual marker. Building on an earlier question of mine I've realized it's not enough to just update a DOM element's CSS, but rather my app should be implementing changes based on data attributes to fully get the functionality I want.

            From this question I know that this should be done by extending the L.Icon class that Leaflet provides, but the answer is a bit too terse for my current JS skills. I apologize for this effectively being a "ELI5" of a previously asked question, but I'm not sure where the options and slug come into function. I think they're implied by the question, rather than the answer I'm citing and being set on the marker itself.

            Here's a simplified version of the the click handler on my markers, which grabs and zooms to location, gets feature info, and populates that info to a div. The zoom functionality works, as does extracting and placing the feature info, but I'm struggling with how to connect the functionality to trigger the modal and place the div with the feature info over the map.

            So, it's a work-around to setting the data attribute, but I realized I was shoe-horning a solution where it wasn't needed. Assuming someone ends up with the same mental block. Appropriate listeners on the modal close button and another function passed to the existing marker click listener produce the desired functionality.
