Fig. 1 The investigation of the status of green fields in urban parks
In this process, there is a key part of a few particularly noteworthy:
(1) Select the type of sensing time and photograph due to a natural phenomenon of a certain periodicity, the type of plant growth, the detector senses the presence of the corresponding data also are differences, determining the appropriate time to photograph extraction the efficiency and accuracy of data has a significant role.
Conclusions In urban green fields planning and construction process, when it is combined with the use of GIS and RS technology, it has access to timely and accurate information, mapping fast, high utilization data, high efficiency and other obvious advantages objective planning and advanced technology can save a lot of viable 8 human and material resources, which will produce a wide range of social and economic benefits.
