To share knowledge in an resources and environment information system

it is necessary to find an approach to manage data

which includes spatial data

remotely sensed data

attribute and knowledge

and models

which consists of spatial analysis models and spatial decision support models. Our approach of solving the problems is to create an integrated frame for metadata of resources and environment information and method metadata of environmental modelling

and integrate data and models in the resources and environment information system based on the frame. In context of the resources and environment information system

data usually include attribute data

vector data

raster data

and knowledge data on narrow sense. Its metadata defines the specifications

qualify control and information sharing for the narrow sense data. And some standards for the metadata had been established. This article considers that it is essential to normatively describe ways and means of environment modeling to share knowledge about modeling

so puts forward the concept of method metadata to standardize descriptive information about environment modeling for the first time. We think that the integrated metadata frame should consist of the metadata about the data and the method metadata about models. In development and operation of resources and environment information system

we can integrate database

remote sensing

geographic information system and environment modeling based on the integrated metadata frame

due to these two kind of metadata adequate describing characters of data and data processing in the system. The integrated metadata frame will be adopted to integrate and share data and models by some projects

such as the resources

environment &district economy information system

and the research on quantitative remote sensing. It is positive that the integrated metadata frame will do a good job.
