2) boundary point geography information in farmland region is obtained：Service precision is less than 6m GPS instrument, the side in required farmland region
Boundary, carries out a fixed-point operation every 3~6m, obtains the latitude and longitude information of the point；
3) modification of geographic coordinate system：By the farmland high definition satellite map and farmland region boundary point of gained in above-mentioned steps
Geography information is imported in Arcmap softwares, and geographic coordinate system is revised as to consistent coordinate system；
4) farmland high definition satellite map aligning：The farmland high definition satellite map of gained, farmland region boundary point are existed
Display error in Arcmap softwares, and be adjusted, until mean error is maintained in the range of 10~15m；
5) farmland electronic map is drawn：In Arcmap softwares, farmland high definition satellite map is amplified, used " iso-surface patch "
Instrument, takes a little along the border in each piece of farmland, draws out the electronic map and crop-planting region electronic map in every piece of farmland.
In the high definition satellite map obtaining step, the time required to being downloaded for reduction, selected areas is to comprise only farmland kind
The Minimum Area of growing area.
The weather continuous sunny time is selected to enter in the farmland region boundary point geography information obtaining step, during measure
OK, GPS instrument is maintained at the position into 45 degree of angles with ground.
In the amendment step of the geographic coordinate system, geographic coordinate system needs to be selected according to oneself research, uses
WGS84 geographic coordinate systems.
By adopting the above-described technical solution, compared with prior art, the present invention has longitude and latitude according to high definition satellite map
Spend information, using the higher high definition satellite map of definition as reference, the farmland region boundary point longitude and latitude determined using GPS instrument
Information correction high definition satellite map geographical coordinate is spent, farmland electronic map is drawn out..
