We wrote a blog entry a while back called ‘Hot Topics in Mobile GIS’. This was a summary of some of the many client conversations we had in 2011, talking about mobile GIS. Moving away from the use of pen and paper while working in the field, was often mentioned. It remains common for field workers to record data using a pen, notepad and paper map. And to then reassemble their thoughts and notes when back in the office. Inaccuracy and inefficiency seemed a common concern. One client said:
“In our ideal world we would simply give our field workers a mobile device loaded with a mobile GIS app. The worker could then annotate the map on the mobile device, store the annotation on the device and either load it into a GIS application running on their PC when back in the office, or send it to an office based employee to do the same”.
Mobile GIS Flexible Frameworks
Around 6 months ago, we released GeoMobile for ArcGIS; a free mobile app in the iOS, Android and Blackberry app markets. This came from our work writing an article for the Winter edition of ArcUser called ‘Developing a Custom ArcGIS Application for the iPad 2’. GeoMobile for ArcGIS is a flexible cross platform framework written in Mobile Flex. We have found this flexibility to be very useful for extending and customising mobile GIS functionality. Building on this work, we are actually in the process of writing an open source equivalent called GeoMobile for GeoServer.
I digress. Given our clients ‘perfect world’ statement above, we decided to use the GeoMobile for ArcGIS framework to build this ‘perfect’ functionality. The ESRI Flex Viewer for ArcGIS has an advanced drawing widget, which allows users to both annotate an ArcGIS map and save and open the annotation. Perfect. We took this widget and ported it to GeoMobile for ArcGIS; made some adaptations and the results you can see demonstrated in the video link below:
Now field workers can annotate to their hearts content on their mobile. Add lines, points and polygons. Make notes, right on the map. Pipe broken here. Tree down there. Save this off and open it in the Flex Viewer for ArcGIS on their desktop in the office. And move forward.
We think this could be a mobile solution many organizations could find useful. We plan to build this type of functionality into GeoMobile for GeoServer. We’d be interested in your thoughts; is this mobile GIS functionality you could use within your work flow?
