北京测绘学会2004年工作总结(摘要)

一．学会全年工作回顾 学会今年工作较多。但由于组织得较好．总体上忙而不乱，紧张有序，而且件件工作受表扬。     

《测量学通用基础教程》出版

《测量学通用基础教程》（刘谊、汪金花、吴长悦编）一书在学校暑假开学前由测绘出版社出版。     

Relationship of Uncertainty and Line Segment for Between Polygon Segment Spatial Data in GIS

The mathematic theory for uncertainty model of line segment are summed up to achieve a general conception, and the line error hand model of εσ is a basic uncertainty model that can depict the line accuracy and quality efficiently while the model of εm and error entropy can be regarded as the supplement of it. The error band model will reflect and describe the influence of line uncertainty on polygon uncertainty. Therefore, the statistical characteristic of the line error is studied deeply by analyzing the probability that the line error falls into a certain range. Moreover, the theory accordance is achieved in the selecting the error buffer for line feature and the error indicator. The relationship of the accuracy of area for a polygon with the error loop for a polygon boundary is deduced and computed.     

Land-Parcel Land-Use History as a Key to Site Selection for Documenting Soil Contamination Risk： a Case Study from Australian Suburbia

In that orcharding in early-to-mid twentieth century southeastern Australia involved use of certain heavy metal and As compounds in regular pest-control spray procedures, some interest attaches to the possibility that these landparcels are underlain by soils with above-background Cu, Pb and As levels. Interpreta- tion of Land-cover changes allowed land parcels previously occupied by orchards to be identified in the 1950s through time-series air-photos. A comparison of soil analysis results referring to soil samples from control sites, and from land parcels formerly occupied by orchardists, shows that contamination （above-background） levels of cations in the pesticides can be found in the top 6 cm of former orchard soils. It is clear that digital spatial data handling and culturally-informed air photo interpretation has a place in soil contamination studies, land-use planning （with particular reference to re-development） and in administration of public health.

四川钙芒硝矿硐室水溶法开采与三级矿量平衡之探讨

为了确定采掘平衡的定量比例关系，按照开采准备程度，将水平开拓、采区准备和回采工作面的三类巷道圈定的各级别储量称为开拓矿产量、准备矿产量和回采矿产量，简称“三量”。用“三量”来反映采掘工程的经济技术指示、生产准备情况和采掘关系，以保证生产的正常接续，以此确定制硝系统的年生产规模、企业工业硝水浓度。     

房产测绘平面图系统的实现研究

随着城市规划管理的不断发展．使得城市房产测绘单位采用大型空间数据库管理测绘平面图资料成为必然。通过建立房产测绘平面图系统，可以有效地解决数据标准不一致．图数不能互访，测绘各部门无法协调一致等问题，充分发挥网络功能，提升整个城市的房产管理水平．达到房产管理和房产服务一体化的目标。本文详细论述了房产测绘平面图系统的概念、设计原则和系统功能．在南京数字房产共享平台的建设中得到了实现．并取得了良好的效果。
