It illustrates local map distortion by generating distortion grids, displacement vectors, and new isolines of scale and rotation. MapAnalyst additionally computes the old map's scale and rotation, as well as statistical indicators summarizing the map's geometric accuracy. It offers a user-friendly interface and is freely available for all major computer platforms at . Map historians are invited to use MapAnalyst, and are encouraged to consult and improve the free Java source-code. <\/jats:p><jats:p> This article describes the steps leading to visualizations of a map's planimetric accuracy. It provides basic algorithmic information that is necessary for the understanding and correct interpretation of displacement vectors and distortion grids. It also introduces isolines of equal scale and rotation, a new type of accuracy visualization. The last section interprets sample visualizations for an eighteenth century map. <\/jats:p>","DOI":"10.3138\/carto-v42-1-089","type":"journal-article","created":{"date-parts":[[2007,6,20]],"date-time":"2007-06-20T16:43:33Z","timestamp":1182357813000},"page":"89-94","source":"Crossref","is-referenced-by-count":50,"title":["Visualizing the Planimetric Accuracy of Historical Maps with MapAnalyst"],"prefix":"10.3138","volume":"42","author":[{"given":"Bernhard","family":"Jenny","sequence":"first","affiliation":[{"name":"Institute of Cartography \/ ETH Zurich \/ Switzerland"}]},{"given":"Adrian","family":"Weber","sequence":"additional","affiliation":[{"name":"Institute of Cartography \/ ETH Zurich \/ Switzerland"}]},{"given":"Lorenz","family":"Hurni","sequence":"additional","affiliation":[{"name":"Institute of Cartography \/ ETH Zurich \/ Switzerland"}]}],"member":"1696","reference":[{"key":"B1","volume-title":"Verfahren zur Genauigkeitsanalyse f\u00fcr Altkarten","author":"Beineke D","year":"2001"},{"issue":"4","key":"B2","volume":"17","author":"Blakemore MJ","year":"1980","journal-title":"Cartographica"},{"key":"B3","first-page":"33","volume":"18","author":"Forstner G","year":"1998","journal-title":"Cartographica Helvetica"},{"key":"B4","first-page":"35","volume":"17","author":"Forstner G","year":"1998","journal-title":"Cartographica Helvetica"},{"issue":"8","key":"B5","doi-asserted-by":"crossref","first-page":"1905","DOI":"10.1029\/JB076i008p01905","volume":"76","author":"Hardy RL","year":"1971","journal-title":"Journal of Geophysical Research"},{"key":"B6","first-page":"113","volume-title":"Five Centuries of Map Printing","author":"Harris EM","year":"1975"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.3138\/RM86-3872-8942-61P4"},{"issue":"2","key":"B8","doi-asserted-by":"crossref","first-page":"351","DOI":"10.1111\/j.1467-8306.1966.tb00562.x","volume":"56","author":"Tobler WR","year":"1966","journal-title":"Annals of the Association of American Geographers"},{"issue":"3","key":"B9","doi-asserted-by":"crossref","first-page":"187","DOI":"10.1111\/j.1538-4632.1994.tb00320.x","volume":"26","author":"Tobler WR","year":"1994","journal-title":"Geographical Analysis"},{"key":"B10","unstructured":"Wagner, H\u2018Das R\u00e4tsel der Kompa\u00dfkarten im Lichte der Gesamtentwicklung der Seekarten.\u2019.Verhandlungen des elften Deutschen Geographentages zu Bremen am 7., 8. und 9.
