If you are working with latitude/longitude coordinates and you get an error of a couple of hundred metres, you most likely are using the wrong datum. New Zealand is changing to a new coordinate system for general mapping. New Zealand Transverse Mercator projection (NZTM) is replacing New ...
The definition of the map projection for projected coordinate systems. Other measurement system properties such as a spheroid of reference, a datum, and projection parameters like one or more standard parallels, a central meridian, and possible shifts in the x- and y-direc...
A datum, and A projection. Knowing your coordinate reference system is essential when: setting up a new site using a known point to process your AeroPoints data Setting up a local grid with a JXL or GC3 file for your site uploading any preprocessed data downloading data from Propeller compa...
The terms 'geographic coordinate system' and 'datum' are used interchangeably, but as noted above, a GCS includes a datum, spheroid, units of measure and a prime meridian. The coordinates for data change depending on the datum and spheroid on which those coordinates are based, even if they ...
What is the difference between: A GCS and a PCS? A datum and a geographic coordinate system? A projection and a projected coordinate system? WKT and WKID? The Define Projection tool and the Project tool? Projection on the fly and geographic transformations?
The datum includes a spheroid, which is defined by its semi-major axis, semiminor axis, and inverse flattening values. What’s the Difference between a Projection and a Projected Coordinate System? A projection is one parameter in a PCS. The projection is the mathematical algorithm that defines...

You can choose to ignore the extents of basemaps when determining suitable datum transformations. Available coordinate systems and transformations have been updated through EPSG v11.015. New vertical transformations based on geoids, quasi-geoids, or other conversion grids can transform to or between grav...
The following example is the string representation of the California State Plane Zone, which is a projected coordinate system (PCS), with a wkid of 3857. You can see that it references the same DATUM, SPHEROID, PRIMEM and UNIT fields as the 4236 projection expalaind in the GCS section ear...
