In the frame of an international project in agriculture monitoring, I have to propose a mobile app that will be used as a reference for field working. The minimum requirements of such an application are:
- visualize the real time geo-location on a background map or satellite image (manually uploaded)
- possibility to pinpoint and label the crop type (i.e. add a vector layer with attribute via forms)
- possibility to work offline (i.e. loading the background image in memory)
- multi-platform (phone/tablet, Android(priority)/iOS...)
Several apps have already been identified (Geowiki pictures, GIS cloud, Poimapper, Wolf-GIS, GeoODK collect, Opendatakit, Geopaparazzi, GeoNode, ESRI ArcGIS) but none of them (at least at this point of the analysis) completly fulfilled the requirements. Do you have other suggestions ?
