What is EPSG:3826?
TWD97 / TM2 zone 121, the national grid of Taiwan's main island, a 2-degree Transverse Mercator centred on 121° east.
What are the units and axis order of EPSG:3826?
Metres, counted from a false origin of 250,000 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:3826 in QGIS?
To show the map in it: Project > Properties > CRS, search 3826. To save a layer in it: right-click the layer, Export > Save Features As, and pick EPSG:3826. Set Layer CRS only labels a file whose system is missing; it does not move the data.
Is EPSG:3826 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.
