The results also show that based on landscape map at 1∶(100 000) scales,the range of appropriate grain for landscape index of Jinghe Watershed was 30m to 40m.
Moreover,it points out that along with the development of spatial database,map database will be replaced by spatial database finally and it will provide multiplescaled map services and all kinds of space time-scaled geographical information services.
In particular, the results in this article show that the oscillations of a function at large scale are comparable to the oscillations of its samples on an appropriate discrete set of points.
In this paper we analyze solutions of the n-scale functional equation Ф(x) = Σk∈?Pk Ф(nx-k), where n≥2 is an integer, the coefficients {Pk} are nonnegative and Σpk = 1.
This criterion implies several results concerning the problem of integrable solutions of n-scale refinement equations and the problem of absolutely continuity of distribution function of one random series.
Using a 30-cM map scale and including the 24 unlinked markers and the ends of the 13 linkage groups and nine linked pairs, the set of RAPD markers accounts for approximately 2160 cM or 64-75% of the genome.
The attitude of the stretching and mineral lineation in the mylonites varies due to late refolding at map scale, but the sense of movement can be estimated, being roughly top to the SE.
Data of the large-and medium-scale soil mapping are not lost upon the generalization procedure due to the reflection of soil combinations on the small-scale map, which makes the latter very informative.
This paper elucidates the question of asymptotical behavior of the expected optimal value of the large-scale MAP whose assignment costs are independent identically distributed random variables with a prescribed probability distribution.
Therefore, even in the absence of an explicitly spatial broad-scale map, it may be possible to study spatial processes by understanding which local-scale characteristics of space are important.
