Frequently asked questions

What is EPSG:5070?

NAD83 / Conus Albers, the equal-area projection of the contiguous United States used by USGS for national datasets such as the National Land Cover Database.

What are the units and axis order of EPSG:5070?

Metres, counted from a false origin of 0 m east and 0 m north. Most GIS software writes easting first, then northing; check the order of your source data when a point lands in the wrong place.

How do I use EPSG:5070 in QGIS?

To show the map in it: Project > Properties > CRS, search 5070. To save a layer in it: right-click the layer, Export > Save Features As, and pick EPSG:5070. Set Layer CRS only labels a file whose system is missing; it does not move the data.

Is EPSG:5070 the same as WGS 84?

Nearly: its datum sits within two metres of WGS 84, so the converter applies no shift between them. For survey-grade work, use the official transformation of the national mapping agency.
