Proyeksi peta silindris katentuang antuk rumus sane ngubungin koordinat geografis garis lintang lan garis bujur ka koordinat Cartesian saking peta antuk titik mawit ring equator lan sumbu x ring salantang khatulistiwa.
A cylindrical map projection is specified by formulae linking the geographic coordinates of latitude φ and longitude λ to Cartesian coordinates on the map with origin on the equator and x-axis along the equator.
