kandi X-RAY | Mercator Summary
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.

QUESTION
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/
So I first found the bounds of the geojson :
...ANSWER
Answered 2022-Mar-20 at 08:06A 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 recently started using the stars R package. I'm struggling with reassigning NA values to "Unknown". I found a potential solution here, but it doesn't seem to work on NAs. Any suggestions to fix this issue are greatly appreciated. for some reason SO doesn't like huge chunks of code without adding more information, so i'm adding some random text at the bottom.
Here's the code that I used:

I've downloaded a world map and want to change it from the default CRS (EPSG:4326) to the WGS 84 / Pseudo-Mercator projection used in applications like Tableau and Google Maps (EPSG:3857). For some reason, when I attempt the transformation, the longitude and latitude numbers become inflated.
For example, (-95.160, -95.102) becomes (-10593226.108, -10586797.584)

QUESTION
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.
Some Code
plane script
...ANSWER
Answered 2022-Jan-14 at 16:17This question is related to a much larger tile-based earth question which I still haven't solved
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 SolutionI 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.

QUESTION
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:

QUESTION
I’m trying to convert a full globe Robinson Projection to Mercator. For example, I use this image.
First, I apply geo-tagging:
gdal_translate -a_ullr -180 90 180 -90 -a_srs ESRI:54030 source.jpg source_tagged.tif
and finally warp it to Mercator:
gdalwarp -t_srs ESRI:54030 -s_srs EPSG:3857 source_tagged.tif target.tif
The outcome is slightly stretched vertically but nowhere near proper Mercator. What am I doing wrong?
...ANSWER
Answered 2021-Oct-13 at 22:02There 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:
