Options:
- Import Topography - allows import of the topographic survey in different formats:
- Ag. Survey (.ags)
Description: Import of freeform elevations and other collected points. Will require processing within OS before design functions can begin.
Format: 4 column CSV. Can have header line. Latitude (deg), Longitude (deg), Elevation Existing(m), Code
Elevation is always be assumed to be meters. It should be the Altitude given in the standard NMEA GGA string as by default this is corrected to the 10x10degree geod built into every GPS. 0mb_4g --> First point in file is always assumed to be the master benchmark. It can be called anything but reference point for the rest of the points.
0cp01 --> Special points (eg benchmarks or points of interest) start with a leading 0 significant
2PER --> Perimeter. All polylines or polygons including perimeter start with a '2'.
3GRD --> Elevation point. All random points start with a '3'.
21E --> All polylines or polgons start with a '2'. some sort of named elevation path. like a bank, or ditch.
It possible to supply a file that only has 3GRD points but first point will still be assumed to be the Master Benchmark.
Coordinate System: Latitude, Longitude, Elevation (m) on WGS84 Datum.
Note: Elevation must be in meters but user can select Feet if required during import to use feet in the software.
Eg: https://www.dropbox.com/s/wye7cx5o80wxtp9/OSFiles01.zip?dl=0 - Drone Deploy Points (.xyz)
- Generic Survey (.enz)
Format: as per Trimble WM Survey File above but no point number required in first column.
Eg: https://www.dropbox.com/s/mir90be3fwsruof/GenericSurvey.xyz?dl=0 - GeoJson (.json)
- GeoTiff (.tif)
- John Deere Operations Center - link the Operation Center and upload the selected topographic data of a field
- LandXML (.xml)
- Shapefile Zipped (.zip) - zip file should contain .shp, .shx and .dbf files
Format: point shape file
Eg: https://www.dropbox.com/sh/vx7jh3jpdkie2b8/AABR9PpSmgfDvayIh9cpmZ7Ma?dl=0 - Trimble Multiplane (.txt)
Format: point number, easting, northing, elevation, code
First line with Master Benchmark with code 'MB', latitude, longitude
Other Benchmarks with code 'BM1', 'BM2', etc
Boundary polygon with code 'B'
Coordinate System: Local XY (True North) with Elevation on WGS84 Datum
