Mercator is a PHP library typically used in Web Site, Content Management System, Wordpress applications. Mercator has no bugs, it has no vulnerabilities and it has low support. However Mercator has a Non-SPDX License. You can download it from GitHub.

When setting up a Multisite install, the network is configured to create sites either as subdomains of the root site (e.g. subsite.network.com) or subfolders (e.g. network.com/subsite). Domain Mapping is the process of mapping any arbitrary domain (called an alias) to load a site. If an alias of arbitrarydomain.com is set for the site network.com/subsite, the site and wp-admin interface can be accessed over either the alias or the original URL. Internally, Mercator looks at a request's domain and informs WordPress what set of tables to use. User authentication cookies are set for all domains in the network, so a user logs in on one site and is authenticated across all.

            Aligning Natural Earth Geojson and Raster to render in D3
            Asked 2022-Mar-20 at 08:06

            I am trying to render the world map with elevation data using D3.

            For this I use Natural Earth 50m land geojson : https://github.com/martynafford/natural-earth-geojson/tree/master/50m/physical

            And Natural Earth elevation raster data : https://www.naturalearthdata.com/downloads/50m-raster-data/50m-shaded-relief/

            I am using this tutorial : https://datawanderings.com/2020/08/08/raster-backgrounds/

            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+):

            Unity 3d - Web Mercator image to Sphere Shader
            Asked 2022-Jan-14 at 21:18

            I'm using a Web Mercator image to cover a sphere. My shader takes a plane with an image and turns it into sphere. The only issue is that The resulting sphere ends up with countries stretched (like the united states).

            I've figured out that I can use an equlateral image of earth to get the desired effect of non-stretched countries

            Question

            For my project I only have web mercator imagery and I've been struggling with the math for getting my shader to show countries at their correct scale. How can I transform mercator lat lon to equilateral lat lon for writing to my shader ?

            NOTE

            Everything I would need seems to be on this question about mercator projection to equirectangular but for whatever reason it's just not clicking.

            BUT

            I was able to figure out how to solve this sub-question by using math from a potentially helpful answer I mentioned earlier in the OP

            The Solution

            I took the some of the shader code from @Pluto's answer and merged it in with my current shader. I assigned a web mercator image to a plane that also had this shader attached to it. The default "Projection" shader param is 0 so everything is already set to convert the mercator image to equirectangular and viola~ the image is rendered as equirectangular on a sphere.

            Extracting the measurement unit (degrees, metres, etc.) from spatial data in R
            Asked 2021-Dec-21 at 15:05

            I would like to extract the unit of measurement (decimal degrees, metres, feet, etc.) from a spatial object in R. For example, if I have an SF data frame that uses the WGS84 co-ordinate reference system (EPSG:4326), I would like to be able to determine that the co-ordinates are specified in decimal degrees. Similarly, I'd like to be able to determine that UTM co-ordinates (e.g. EPSG:32615) are specified in metres.

            I have tried using the st_crs() function from the sf package, which returns the co-ordinate reference system in well-known text format. However, I'm struggling to be certain that a regex that extracts the unit of measurement from that well-known text will operate reliably for a wide range of co-ordinate systems.

            Is there an existing function that returns the measurement unit for a spatial object?

            For example, the following code produces an SF data frame that uses the WGS84 co-ordinate system:

            There are a couple of issues in your commands. The first is that -180 90 isn't in the top left corner pixel of global Robinson projection GeoTIFFs. The top left corner would be something like -338.2187147689 90, and the bottom right would be 338.2187147689 -90. However, you're also specifying your srs as ESRI:54030, so those bounds need to be in projected coordinates, not lat/lons. The command to generate a GeoTIFF from your image would be:
