I am in the ag field and no time or resources for learning or buying GIS to solve one problem.
I have a shapefile that came off a Raven monitor in a tractor that was used to plant a crop.
I use AgLeader SMS to pull the shapefile in and then I can analyze aspects of it as it relates to agriculture.
The problem I am having with 1 shapefile, in particular, is its projection when I read it in.
I have figured out the centre of the projection is in Mexico while my field is in Iowa and the field is such a small speck on the map, I cannot find it.
I have made a copy of the files and have opened the .dbf file with MS Access and have found by sorting that there are 3 records that contain 0.000 in the Lat field. I have tried to delete those records and save the database as a dBase III, IV and 5 file and SMS will not read it in now.
Am I missing something here on how the .dbf, .shp, .shx and .prj files are linked? Is there an easier way to edit these? I know the data is there, it has over 13,000 records.
