  38. 38. Enebro • Very good software, quite fast and free • Not open development, no public repositories • No developer documentation • Confusing license • Very few spread6-9th Sept. 2010
  39. 39. Very light applications • Application like gvSIG Mini or TangoGPS that support only tiles (OSM, yahoo maps...) or WMS are fast and light and powerful • This kind of applications are growing in number • With a few more work is possible to add custom forms and POI creation to do asset inventory and maintenance and incidence reporting6-9th Sept. 2010
  40. 40. New devices and platforms • Android and iOS devices are “cheap” and powerful, include cameras, aGPS, WiFi and CellId based location, compass, accelerometers, light sensors and so on. • The new boom of tablets provides bigger screens with small weights and good battery consumption • Multitouch screens require new interfaces • The number of users is astonishing6-9th Sept. 2010
  41. 41. Layar and Augmented Reality • Augmented reality provides users the possibility to see located objects over the real world • The spread of Layar is *15 the spread of ArcPad • ¿Could it be interesting for the GIS community to use mobile AR professionally?6-9th Sept. 2010
  42. 42. Web based touch applications • There are some initiatives to make the web mapping possible on mobile • TouchMapLite • Openlayers • more? • With HTML5 personal database is possible to have offline data • We will keep an eye on those projects6-9th Sept. 2010
  43. 43. Desktop applications optimized for mobility • Beegis is an application developed to be used by geologists on outdoor surveys • Is built on top of Jgrass, so it has a lot of functionality • It works on tablet-PCs • Its key functionalities are • Geonotes tool • GPS tool6-9th Sept. 2010
  44. 44. The number of applications • We searched very hard for FLOSS mobile Geo applications with very few results • Did we missed any important software? • What are the reasons for such a few results?6-9th Sept. 2010
  45. 45. Are the OS applications comparable to ArcPad? (I) • In both FLOSS apps and ArcPad Is possible to: • field mapping • inventory and mantainment of assets • incidence reporting • inspections • ArcPad does not support any open or OGC format • Performance is perfectly comparable and in some cases gvSIG Mobile is even faster6-9th Sept. 2010
  46. 46. Are the OS applications comparable to ArcPad? (II) • ArcPad has great documentation, a good customization framework and good integration with ArcGIS • gvSIG Mobile (the most complete OS App) does not support rangefinder or dgps or camera and geometry editing is poor compared to ArcPad at this moment6-9th Sept. 2010
  47. 47. To do • FLOSS Mobile GIS still have to work on • Making better documentation and tutorials • Making the software easier to install and use • Expand the user and developer community • Support professional equipment like rangefinder and dgps • Keep an eye on new interactions (multitouch), new hardware (+1GB RAM, Sensors), new approaches (AR) and new possibilities (HTML5, WiFi and CellID location)6-9th Sept. 2010
