I need to be able to draw a polygon in the field while the landowner is there to approve it. Is there an app that is easy to use so all of the field hands can operate it? I also need to be able to export the file to be used in the equipment used to spray.

There is an app for iOS devices that might be what you want. My Maps Editor can export to KML/KMZ and works with your Google Account.


At Cost

GISRoam – iPad Mobile Professional GIS

GISRoam WebConnect Access $9.99
GISRoam Pro $149.99
GISRoam Upgrade to Pro $129.99

GISRoam's App Features (requires a DataConnect activation):

• Terrain Profile display based on two points and elevation file

• Measuring now displays the elevation from the elevation file along with Lat/Long position

• User defined user forms for data collection and data display. Including pre-defined attribute table values in text/numbers/pictures/weblinks - editable while you roam.

• Collect new shape features (Polygon, Line, Point) in new or existing Shapefile with and without the GPS



Another option is an online tool called click2shp -- it is entirely browser-based, and it allows you to draw points, lines, and polygons on top of a Google Maps basemap, and save the features as a shapefile in a single click. It works on my iPad!


I haven't been able to find one that I like, but iCMTGIS II or PrecisionEarth might provide what you're looking for at about $100 each.
