The most popular online map services are selected based on worldwide website traffic data, provided by specialized sites, such as Similarweb, in terms of global coverage and popularity among users. Online map services are commented based on cartographic principles, conventions and traditional practices addressing topics, such as: Cartographic projection, orientation, scale, marginalia, content (thematic layers), symbology, generalization, annotation, color use and overall map design. Color schemes utilized in web maps are discussed in more detail, since based on studies concerning the selection of the preferable map by experts and laymen, color is undisputedly the most frequently mentioned factor. It can be stated that online map services generally adopt well-known cartographic practices, which are not always applied as expected. Moreover, suggestions for the improvement of online map services are made regarding cartographic projection, legend, content, symbolization, color, etc.<\/jats:p>","DOI":"10.3390\/ijgi8050215","type":"journal-article","created":{"date-parts":[[2019,5,9]],"date-time":"2019-05-09T11:22:35Z","timestamp":1557400955000},"page":"215","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Online Map Services: Contemporary Cartography or a New Cartographic Culture?"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6855-4980","authenticated-orcid":false,"given":"Andriani","family":"Skopeliti","sequence":"first","affiliation":[{"name":"Cartography Laboratory, School of Rural and Surveying Engineering, National Technical University of Athens, 9 Iroon Polytechniou, 15780 Zografou, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leda","family":"Stamou","sequence":"additional","affiliation":[{"name":"Cartography Laboratory, School of Rural and Surveying Engineering, National Technical University of Athens, 9 Iroon Polytechniou, 15780 Zografou, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"129","DOI":"10.1179\/174327708X305120","article-title":"Usability evaluation of web mapping sites","volume":"45","author":"Nivala","year":"2008","journal-title":"Cartogr.
