“Geopaparazzi: never out of data in the field”
2019-08-26, 09:00–13:00, Room 10
The workshop is dedicated to professionals, researchers and students that needs to collect data from the field and use this information to update or create GIS data, but also to OpenStreetMappers as well as tourists that want to keep a geo-diary.
Geopaparazzi is an easy to use and intuitive mobile application for digital field mapping for Android devices developed to support the work of the technicians in the field, offering a mapping environment with real time GPS position and the possibility to take georeferenced notes, georeferenced and oriented pictures and georeferenced sketches. Furthermore, Geopaparazzi provides a powerful support for structured data collection based on customized forms. Forms may contain combo and check boxes, text fields, pictures and sketches organized over multiple tabs. Background data on the map view can be personalized using available local data or on-line services with the possibility to use vector offline Mapsforge basemaps, Mbtiles offline databases, TMS and WMS services. Vector layers in Spatialite DB can be visualized in the map view with a style prepared on the device or directly imported in the DB from SLD style files and edited with simplified tools developed to be used on a device in the filed.
In the last years we developed some applications in the HortonMachine library to support Geopaparazzi, which supply an userfriendly GUI with specific functionalities to: prepare the base raster data for the map view in Geopaparazzi, prepare the overlay vector layers as Spatialite DB with the support of the styling (original SLD), prepare the forms with all the detailed sections, visualize and export as shapefiles of all the data collected in the field (GPS tracks, text notes, pictures and form based notes).
The workshop starts with an introduction of the application, installation and description of the main features. Then a short section will be dedicated to the preparation of the input data: background maps, vector layers and forms. Following these sections there is a practical testing of Geopaparazzi outdoor in the field. The last section, back in the room, is dedicated to the export of the collected data. The data collected can be visualized or used directly in a GIS environment using everyone’s preferred GIS or can be synchronized with the data collected by the other surveyors of the team using the new web application Geopaparazzi Survey Server.
