Data collection solution for forestry survey and patrol inspection

| Current situation of field data acquisition ：

1、 Paperwork , Field work requires a large number of paper maps , Draw the outline of Lin Ban by hand , Unable to determine the location, area and other information of the forest class ;

2、 When the field forest team collects , harsh , Operation equipment is easy to be damaged , Affect the work process ;

3、 The relative position of the image cannot be accurately located , Unable to ensure that you have reached the job location ;

4、 The accuracy of field data collection is poor , Data quality cannot be guaranteed ;

5、 Manually fill in a large number of ground class attributes 、 Ownership and other attributes , Records are cumbersome and data is easy to lose ;

6、 Data collection results in the field need to be in the office ArcGIS And other related software , Repeat the work , laborious ;
