Geographical Information (GIS)

The quality of printed maps available in Italy varies enormously depending on the geographical area covered. The prime tourist areas (such as the Alps) are well documented, but the Apennines much less so.  In response to an EU initiative (Directive 2007/2/EC), each region of Italy has produced Geographical Information System (GIS) data which can be accessed online. This includes information on flood plains, the distribution of flora and fauna, population density, earthquake susceptibility, footpaths etc all superimposed on monochrome maps and/or aerial photographs of the regions concerned.

To view the GIS data the most widely used free application is QGIS (previously known as Quantum GIS) which may be downloaded here.  This software (which is available for Windows, Mac, Linux, BSD & Android) is extremely powerful and comprehensive, especially when used in conjunction with third party plug-ins. The learning curve is very steep, but once mastered there is little that QGIS is not capable of. Be aware, though, that no data are provided with QGIS – to make it useful one must link up to the Toscana WMS database (available here). Furthermore, the data cannot be downloaded for use offline – instead they must be viewed in real time online. Hence a fast internet connection is required if the constant redrawing of images on the screen is not to become tedious and tiring.

Be warned that the Toscana GIS data have not been updated since they were originally uploaded, and to claim they were incomplete would be a considerable understatement. For example, the footpath data relate to 2005 and incorporate only a tiny fraction of the waymarked paths observable on the ground.

The monolithic nature of QGIS and its reliance on a high speed internet connection means that it is not well suited to many applications. Those interested in footpaths are better served by the cloud-based OpenStreetMap which is far easier to use, more up-to-date and more readily comprehensible (though often less accurate and somewhat inconsistent).  A simple, clear and focussed front end to OpenStreetMap which displays walking routes in a particularly accessible format is – highly recommended.

Standalone software that can often be of use includes:

Garmin BaseCamp This (free) software is aimed at owners and users of Garmin GPS receivers. It is available in Windows and MacOS versions, but not Linux. The software allows maps, routes, tracks and waypoints to be transferred between a Garmin GPS and a PC. User-scanned custom maps and OpenStreetMap derived basemaps can be displayed – the former as overlays. Sadly, several of the most useful original features, such as Garmin’s cloud based data storage facility and adventure sharing, have now (2019) been discontinued and all development has ceased. The most recent bug-free version of the software is 4.6.2 which can be found here. Do not use the later Windows versions (eg 4.7.0 & 4.7.2) as, due to a bug, they won’t allow uploads of custom maps. The bug is reported to be corrected in MacOS version 4.8.9.

Garmin MapSource This (free) package was officially superseded by BaseCamp some years ago but is still available for download and can still be useful – particularly for correcting, joining, splitting and otherwise modifying tracks. Windows only.

QMapShack This free, open source package replicates most of the features of the Garmin BaseCamp & MapSource products and continues to be developed. The interface is a bit clunky and the documentation could be better, but it works well enough. Available for Windows 10 & Linux (64 bit versions only).

Google Earth Pro Most people interested in maps are familiar with this (free) product which is particularly useful for calibrating custom maps as well as for producing presentation materials. It’s available in Windows, Mac and Linux versions.

GPSBabel This package allows users to convert GPS data between all the major formats. Useful from time to time to convert non-Garmin data files to gpx format for analysis/modification in BaseCamp/MapSource. Mac and Linux versions are available. Free, but donations appreciated.

GPSU This provides the quickest way to convert GPS data (essentially tracks and waypoints) from one coordinate reference system to another. Particularly useful for converting latitude/longitude (or Gauss-Boaga as used on the older Italian paper maps) into UTM. It will also calibrate custom maps with a level of sophistication not currently available in Google Earth. The package has been available for many years – and it shows. The interface reminds one of the MSDOS based applications of yesteryear and the graphical capabilities are crude. Don’t be fooled, though, as this software is extremely powerful and is still updated on a regular basis. There’s also an active user group who are always more than helpful to answer user queries. Shareware – free version has limited (but useful) functionality. Windows only.

Microsoft Image Composite Editor Free software designed to stitch multiple images together. Powerful and accurate (but surprisingly little known). Windows only.

Autodesk Design Review Free software to display and print DWF & DWFx graphics files. Useful to convert downloaded maps to PDF format from which a JPEG can be extracted (see Pixillion below). Conversion from DWG and DXF to DWF for manipulation by Design Review can be achieved by downloading the freestanding DWG TrueView package also available from Autodesk. Both packages are Windows only.

Pixillion Useful software for converting maps from one graphical format to another (typically PDF to JPEG). Commercial product with 30 day trial available. Expensive at £30 for what it is, but the conversion is extremely accurate. Available for Windows and Mac.
