Can the Spiritual Weapon spell be used as cover? You can't just add an constant value to geograghic coordinates in EPSG:4326: WGS 84 coordinate system, because the length of two arcs between two different pairs of point on a sphere is depend on latitude. You should not ever trust distances in a Mercator, so first you need to deproject to a geographic coordinate system, then, depending on the range of values either use an appropriate equidistant or equal area projection, or use a geodetic calculation tool.

Some sources say that WGS84 and EPSG:4326 are exactly the same things, others say they are different, but they don't provide the differences. In some cases this is not possible, e.g. section Custom Coordinate Reference System for information on managing your custom In our Postgres/Postgis database we store polygons in a column defined as lonlat/EPSG:4326, as it may contain data from anywhere in the world. For data supported by OGR or GDAL, QGIS relies on the presence of a How can I get roughly what I want, and use the geographical index? As you can see 4326 is the EPSG code representing WGS84, so yes they are the same. It references all the EPSG codes and gives for each: the unit, the ellipsoid, the datum and so on.

We have a requirement to calculate the surface area (i.e. Buffer line between two coordinates with meters, CSV projection not aligned with QGIS OSMap. the list. The problem with Geom is it's ultimately a 2D object. When people refer to rendering data "in EPSG 4326" without further information, this is 99% of the time what they mean (and 70% of the time that is the limit of their conceptual understanding of the matter, anyway coordinate systems and projections are hard). """PROJCS["NAD83(CSRS) / New Brunswick Stereographic". Do you expect that the correct answer is about 8.7 centimeters, which result you can get with this procedure: Find the long/lat coordinates for the EPSG:3857 coordinates: Insert the long/lat coordinates into the ST_Length example that is using geography type in http://postgis.net/docs/ST_Length.html, The cartesian distance for the poins is 1 also for PostGIS.

The ST_Distance/ST_DWithin/etc. I found a function to return the UTM zone for any point on the PostGIS wiki: All projections of locations on the Earth into a two-dimensional plane are distortions, the projection that is best for your application may be different from the projection associated with the data you import. Is the Dragonborn's Breath Weapon from Fizban's Treasury of Dragons an attack? Choosing an inappropriate CRS can cause your maps to look distorted, East fields, respectively. You can test your CRS parameters to see if they give sane results. It is said that unit of measure for EPSG:3857 is the metre. 3454 meters are projected into full width as it were 40000 meters. Obtaining same area values provided by Census for TIGER boundaries using PostGIS functions? Cartesian coordinates, with no relation to positions on the Earths surface. So, while the unit of measurement in EPSG:3857 is indeed meters, as you have correctly spotted, distance measurements become increasingly inaccurate away from the equator. purely numerical, non-earth values, i.e. But, the pixels are interpreted as a meters-distance in relation to the zoom level (and possibly latitude). Why is it not properly recognizing my CRS. If the Make default checkbox is ticked when Is it also 1 meter?". QGIS behavior whenever it cannot automatically determine the correct CRS for a The above refers to UTM, with units in meters, so the area will be sq meters. Therefore, if the available definition is in the proj format, select that your code. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup.
