GEOPAPARAZZI: INTRODUCTION
Geopaparazzi is a tool for digital field mapping. Originally it has been developed for fast qualitative engineering/geologic surveys but it can be used also as a tool for emergency management, general field activities (sport) and tourism.
Geopaparazzi is available on the Android Play Store. Search for Geopaparazzi on your phone or get it from the online android market.
Note: Geopaparazzi doesn't work on iPhone and Windows Phone.
GEOPAPARAZZI: INTRODUCTION
The main aim of Geopaparazzi is to have a tool that:● can be always at hand when needed● gives the possibility to take georeferenced pictures
during the survey, with further possibility to import them into a main GIS application
● is extremely easy to use and intuitive, providing just few important functionalities
GEOPAPARAZZI: INTRODUCTION
The main features available in Geopaparazzi are:● georeferenced notes: text notes, pictures, sketches,
forms ● gps tracks logging● a map view for browsing and navigation of the data● easy export of collected data● simple generation of any type of background map
GEOPAPARAZZI: INSTALLATION
1. connect your Android device to internet
2. open Play Store3. type geopaparazzi within the
Search textbox
GEOPAPARAZZI: INSTALLATION
1. connect your Android device to internet
2. open Play Store3. type geopaparazzi within the
Search textbox4. select to install the first
application found with the name Geopaparazzi which represents the last version (not geopaparazzi3)
5. open Geopaparazzi...
GEOPAPARAZZI: FIRST START
Geopaparazzi requires to turn on the GPS position of the device, if this is not available when starting, the application will ask to activate it.
Activate the GPS positioning following the specifics of your own device.

Take a note
GEOPAPARAZZI: THE DASHBOARD
Place the note in the GPS position or in the last map center coordinates (active only if GPS has fix).
Simple notes can contain:
● text
● picture
● sketch
Complex notes are based on structured forms.
GEOPAPARAZZI: NOTES
Save the picture or take a new one (Take new).
GEOPAPARAZZI: NOTES
Select the type of line and the color and start to draw.

GEOPAPARAZZI: THE DASHBOARD
Some fields are editable to insert the project’s metadata.
GEOPAPARAZZI: PROJECT INFO
GPS logging
GEOPAPARAZZI: THE DASHBOARD
If GPS is logging:
- the logging button will be orange
- the GPS status will be blue
To STOP GPS logging select the same button (in orange) and select to STOP LOGGING.
To START GPS logging select the button and enter a new log name or continue from the last one.
Map view
GEOPAPARAZZI: THE DASHBOARD
GEOPAPARAZZI: MAPS VIEW
● Geopaparazzi by default uses on line services (mapnik)
saving the visualized tiles (and zoom) on the device
● it is possible to use other background maps:
➢ off-line
➢ personalized (type of map and area)
available on the device.
GEOPAPARAZZI: MAPS VIEW
The basemap is loaded from an on-line service considering the GPS position (if the GPS is not active or if there is no internet connection no map will be displayed).
Tap the orange button in the map view to see the menu.

GEOPAPARAZZI: NOTES
Select to place the note in the GPS position or in the center of the map.
Complex notes are possible using customized forms.
Simple notes
To use them, a tags.json file needs to be created and placed inside the geopaparazzi folder inside the sdcard. In that file a json format description of the wanted tags and forms needs to be placed.
By default a sample tags.json is created in the Geopaparazzi installation. It contains form samples and examples to show all supported form widgets.
GEOPAPARAZZI: NOTES
Complex forms can contain different tabs and fields defined by drop-down menu or multiple choices selection.
GEOPAPARAZZI: THE DASHBOARD
GEOPAPARAZZI: IMPORTChoose the format of the data to import as background or vector layers.
browse/import projects from the net
voluntary online service that supplies mapurls
import CSV files that start with bookmarks_xyz.csv and contain lines of the form: label,lat,lon,zoom
create a simple spatialite database with a point, line
and polygon table
GEOPAPARAZZI: EXPORTChoose the format of the data to export (notes, images and GPS tracks).
only direct export that supports proper complex
notes representation
upload the current project in the net
export all the images of the project into a folder
export all the notes as a report in a PDF file
GEOPAPARAZZI: PROJECTS● projects are saved in a single file with the given name
● the first project, created by default in the home directory
of the device is named geopaparazzi.gpap
● when installing the application in the home directory of
the device a new folder will be created geopaparazzi
containing the form definition and all the temporary files
● it is strongly reccommanded to create a new project for
different field surveys to avoid confusion in the
registered data

GEOPAPARAZZI & gvSIG
● the plugin for the support of Geopaparazzi in gvSIG is available at: https://we.tl/ROxgEc267P
● read carefully the installation guidelines available here: https://github.com/moovida/hydrologis4gvsig/releases/download/release_0.1.0___jgt_0.8.1/hydrologis4gvsig_quickstart.pdf
● in gvSIG it is possible to
– visualize a Geopaparazzi project– create the map background data as .mbtile– export and browse the image notes– export all the data contained in the project as
shapefile
GEOPAPARAZZI & gvSIG● the plugins are supplied as a gvSIG package (gvspks)● to install the Geopaparazzi plugin use the standard
gvSIG updtate manager● enter the Addons manager,
which can be found in the Tools menu
● choose the Installation from file option
● select the installation package
● push on next
GEOPAPARAZZI & gvSIG● from the dialog that lists all installed and available
plugins look for the plugins that start with org.jgrasstools.gvsig
● select and confirm that you want to install those plugins
● wait until all the packages are installed
● restart gvSIG
GEOPAPARAZZI & gvSIGlaunch gvSIG and create a new view, then enter the properties and
set the right projection. It needs to be set to the one of the data
the aerial data of France is available for free in
CRS EPSG: 2154
GEOPAPARAZZI & gvSIGDrag the aerial image (TIF) into the map view.
select NON TILED when asked
GEOPAPARAZZI & gvSIGIn gvSIG there is a tool to create the background maps for
Geopaparazzi. The user just sets the wanted zoomlevels and a name and output folder for the database.
GEOPAPARAZZI & gvSIGOnce launched it takes the current view and all layers and
generates an mbtiles database for Geopaparazzi. Pay attention on the upper zoomlevel, it might be hard on your PC and time.
On large areas 19 might be a good
compromise.
