The geoheritage promotion is focused on the abiotic component of the landscape. Despite the geological aspect generally has its highest evidence in natural contexts; the closeness to cities offers good opportunities for touristic promotion. Cities, where Wi-Fi connections, facilities and accommodation are widespread are excellent starting points for extra-urban routes. The paper is focused on the geoheritage of Salta and Jujuy provinces (Argentina). Fluvial and gravitational features, together with structural landforms are the main evidences of the geological history and actual morphogenetic processes acting on the area. The efficiency of the geomorphic agents due to climatic parameters too, creates unique features defined as geosites. In order to promote the knowledge of this heritage a webmap is produced by Lizmap and QGIS Server. To address the lack of network in some areas, data are uploaded in Qfield and Geopaparazzi to be used offline too. Twenty-five geosites are in the project with a summary sheet and a second one with a wider description of the sites. Moreover the possibility to assign a rank in the attribute table of the shape to each geosite, according to specific values (geomorphological, petrographic, structural and so on), allow the users to select only the geosites corresponding to their interests. The use of digital data and operating systems are the starting point for responding to new and modern needs for use.
