Prof. Emer. Miljenko Lapaine, former Chair of the ICA Commission on Map Projections was elected an ICA Honorary Fellow at the ICC2019 in Tokyo




The Pre-Conference Workshop on Map Projections will be held on Sunday, 14 July 2019, 16:00-19:00 local time, in Teikoku-Shoin Co., Ltd. premises which is located three-minute walk from Exit A1 of Jimbocho Station on TokyoMetro Hanzomon line, Toei Shinjuku line or Toei Mita line. The latitude and longitude of the place is about 35 deg 41 min 40 sec and 139 deg 45 min 20 sec.

Teikoku-Shoin Co., Ltd is a leading company that publishes school atlases and textbooks on geography. The website of Teikoku-Shoin Co., Ltd is A map and nearest station information are available on this site.

If you will be able to actively participate at the Workshop, with a short lecture or presentation, please let me know.

Everybody is welcome!

Thank you,

One of the most famous cartographers of our epoch, Prof. Emeritus Waldo Tobler passed away on 20 February 2018. He used computers in geographic research for over fifty years, with emphasis on mathematical modelling and graphic interpretations. Well known for his publications, he formulated the "first law of geography" in 1970 while producing a computer movie, and was the inventor of novel and unusual map projections, among which was the first derivation of the partial differential equations for area cartograms. He also invented a method for smooth two-dimensional mass-preserving area data redistribution. According to Tony Campbel, Waldo was a major figure in the analysis of the mathematics underlying cartography.

He was the most distinguished member of the ICA Commission on Map Projections. Please, visit his web-site to learn more about his extremely rich work and life

Let his work inspire all of us.

Map projections are mathematical procedures that enable the mapping of the earth's or other celestial bodies' curved surface to a plane. The curved surface is usually a sphere or a rotational ellipsoid. The theory of map projections is often referred to as the mathematic cartography. The goal of studying map projections is the creation of mathematical basis for making maps and solving theoretic and practical problems in cartography, geodesy, geography, astronomy, navigation and other related sciences.

This website will inform you about the activities of the ICA Commission on Map Projections, especially on meetings and publications. To stay up-to-date, please contact the Chair Prof. Dr. Miljenko Lapaine (
