What is EPSG:6677?
JGD2011 / Japan Plane Rectangular CS IX, the survey grid of Tokyo and the Kanto region, one of the 19 zones of Japan's plane rectangular system. Japanese surveyors write X north and Y east.
What are the units and axis order of EPSG:6677?
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:6677 in QGIS?
To show the map in it: Project > Properties > CRS, search 6677. To save a layer in it: right-click the layer, Export > Save Features As, and pick EPSG:6677. Set Layer CRS only labels a file whose system is missing; it does not move the data.
Is EPSG:6677 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.
