I think I've found the coordinate system you're looking for.
Your unknown coordinate reference system seems to be referred to in Rwanda as ITRF 2005 / TM Rwanda. It is a projected coordinate system using Transverse Mercator with the following parameters :
False Easting : 500,000
False Northing : 5,000,000
Central meridian : 30
Latitude of origin : 0
Scale ...

Since Mollweide does not accept a latitude shift, what we can do is transform the coordinates of the geometries to a new geographic CRS with the Poles shift.
For that, I will register a custom geographic CRS in the PROJ database, and associate to it a Helmert Transformation.
PROJ registers all data in a SQLite database. I will edit it with DB Brower ...

It is some version of State Plane Nevada East with measurements in feet. For example, choosing ESRI:102707 from the EPSG database (http://epsg.io/102707) yields coordinates in that range near 35.16 N lat, -114 W long.
Note that there are several alternative specifications of the State Plane Nevada East projection, so if you don't get the exact one, your ...

Your coordinates look like they could be in WGS 1984 - Pseudo Mercator (Web Mercator, EPSG 3857. Web maps often use Web Mercator, so it is a likely candidate), or World Mercator (EPSG 3395). In both cases, your example point would fall near the UAE - Oman border. Check to see if one of these fit your data correctly.
Some tools like projfinder and epsg.io ...

Your problem is stated here:
The geometry column in the table has no SRID set (Find_SRID for this table returns 0).
As a result GeoServer considers this unprojected data (it's just numbers not a position) and can't reproject it. GeoServer only considers the SRS of the geometry column not the individual projection of the geometries (which PostGIS doesn't ...

I assume, that you used the EPSG 25832 because it says ETRS89_UTM32 in the field Koordinatenreferenzsystem in the metadata file. However, there are several different variants of this particular projection, one is indeed coded as 25832 by EPSG. The one, that should be used here is probably EPSG 4647, as hinted in the file name of the download link (which is a ...

You can create an osr.SpatialReference() object and then use it to set the raster projection using gdal. If you have gdal installed you'll have osr already. Here is an example:
from osgeo import gdal
from osgeo import osr
# create spatial reference object using your EPSG
sr = osr.SpatialReference()
sr.ImportFromEPSG(32631)
# open your raster and set ...

I created a blank seed file of the drawing file and assigned unit meters and projection system sweref99 12 00 to it. While running a model in the setting of export cad, given seed file as an optional, after that all converted .dwg files are having correct unit and projection system.

The grids are readed from the \share\proj foler.
Depending on the operating system and the installation is where it is located.
In Windows machines it is in the QGIS version folder for stand-alone default installs, or in the OSGeo4W folder for OSGeo4W default installs. In Linux it can be in /usr or in /usr/local.
If you have already the grid file, just ...

It seems to be EPSG:3421. (955999, 26397850) translates to Lat 35.1612555° Lon -114.5801733° at epsg.io.
When looking for projected CRS on the basis of given coordinates, I'm using SHPProjFinder tool. This is local Java program, based on similar algorihms as projfinder.com, but with much improved efficieny.

You should make sure that you specify exactly what you want, meaning:
projection should match the project aoi's projection
the bounding box should match the project aoi's bounding box
the pixel resolution should match the project aoi's pixel resolution
since you are using thematic data, you should use nearest neighbor resampling.
If you warp a raster from ...

You could use proj4.js. Just install it using npm install proj4.
From the documentation:
var firstProjection = 'PROJCS["NAD83 / Massachusetts Mainland",GEOGCS["NAD83",DATUM["North_American_Datum_1983",SPHEROID["GRS 1980",6378137,298.257222101,AUTHORITY["EPSG","7019"]],AUTHORITY["EPSG","6269"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0....

As pointed by mkennedy, the Description of CRS - SI_D48 / SI_TM, from the Information and Service System for European Coordinate Reference Systems, expresses that SI is the 2-digit country code for Slovenia and D48 is the datum.
The description of the projected coordinate system defines also the parameters of the Transverse Mercator Projection conversion ...

I have never gotten getDownloadURL() working and I'm using export.Image.toDrive() as alternative. Perhaps you could use it too.
