Some embodiments of the invention provide a method of automatically bundling environmental conservation items with computed environmental conservation values into “credit blocks” so that the aggregate sum of the environmental conservation values of the items in a particular block is sufficient to issue a tradable environmental commodity, also referred to as a credit. In some such embodiments the various different items represent items with different forms of environmental conservation such as emissions reductions, energy savings, hazardous waste reductions, or generated renewable energy.

In some embodiments, credits with at least one expired item are unbundled and the at least one expired item is removed from the credit block. Some embodiments replace the at least one expired item with at least one valid item having the same or a similar environmental conservation value.

The invention discloses a GPS/INS data direct orientation precision evaluation method, which takes photogrammetric emphasis equation collinearity equation as base and a multi-piece forward intersection of a bundle method as theory basis; the evaluation method is combined with the least square principle for obtaning the coordinate of a ground control point object by compensating calculation; and then a comparison with the actually measured coordinate of the ground control point is carried out for obtaining the error value of the coordinate by the statistics so as to evaluate the direct orientation precision of the outer orientation elements obtained by the GPS/INS system. The method has high evaluation precision and small measurement error, and the evaluation result can be used for manufacture practice directly, thus being capable of effectively avoiding the measurement error of the picpointed coordinate added in manual stereomeasurement; and the algorithm is not limited by image number.
