From charting to mapping: Russian military mapping of Corfu in the early nineteenth century

Abstract

This paper concludes the overview of the Russian Navy's chart making published in Imago Mundi, Volume 52 (2000). In the present paper attention is drawn to the way the emphasis shifted in the early years of the nineteenth century from charting by naval surveyors to land mapping by the Army. The need for specialized military topographical education had led to the founding of the Map Depot in 1797 in St Petersburg. The first major survey undertaken by the Depot was of the island of Corfu (1804–1806), in anticipation of further Russo‐Turkish hostilities (the Third Russo‐Turkish war, 1806–1812).     

Saxton Manuscript Maps and Surveys Not Described by Evans and Lawrence

ABSTRACT

Four surveys by Christopher Saxton and three by Robert Saxton neither listed nor described by Ifor Evans and Heather Lawrence in their book Christopher Saxton, Elizabethan Map-maker, published in 1979, are here presented. Reference is made to another six surveys by Christopher that were not listed by Evans and Lawrence but have been described elsewhere. In view of the rate of discovery, it is concluded that further surveys may yet come to light. Changes in the location of some Saxton materials since the publication of Evans and Lawrence's book are noted in the Appendix.     

Object-based landform delineation and classification from DEMs for archaeological predictive mapping

In this paper we report the results of an experiment with automated landform delineation and classification from digital elevation models (DEMs) using object-based image analysis (OBIA). Archaeologists rely on accurate and detailed geomorphological maps to predict and interpret the location of archaeological sites. However, they have been using high-resolution DEMs primarily for visual interpretation and expert-judgement classification of landform. OBIA can perform these classifications much faster and in a more objective fashion. The method was tested on a study area in the south east of the Netherlands. It is concluded that OBIA is a suitable technique for quick and objective delineation of landform, but needs an improved conceptual framework adapted to the local situation and archaeological questions to better identify and interpret the derived landform objects.

藏族传统体育美学探微

藏民族自古生息繁衍在青藏高原地区。由于特殊的地理环境,藏族人民在长期的劳动中形成了具有鲜明的草原游牧民族文化特色的生产生活方式,创造了绚丽多彩的藏族传统体育文化,如在民间开展的赛马、射箭、“古朵”、赛牦牛等体育活动体现了浓郁的草原游牧民族的风格特征。本文从体育美学与藏族传统体育文化的角度,透视并分析了藏族传统体育的内涵、特征及研究发展思路。     

改革开放以来芜湖市城市空间扩展及驱动力分析

以landsat MSS/TM/ETM+遥感影像为数据源,借助Arc GIS平台,选取城市空间扩展速度、扩展强度、紧凑度、分形维数、重心坐标、扩展弹性系数等指标,运用空间形态分析、叠加分析、等扇分析等方法,分析了改革开放以来芜湖市城市空间扩展时空特征,结合统计数据探究了扩展驱动力。结果表明:1979-2012年间,芜湖市城市空间扩展速度与强度具有较大波动性;人口增长与城市空间扩展的关系渐趋合理;城市空间形态由紧凑型向分散型转变;城市空间沿长江及主要交通线非均衡拓展;城市重心东偏北移;经济、人口、交通建设等是芜湖市空间扩展的主要驱动力。     

Lost in the Mail: the Inherent Errors of Mapping Australia Post Postcodes to ABS Derived Postal Areas

It is now common practice, by users of geographic information, to link data held at the postcode level to that obtained from the national census. This paper examines the relationship between Australia Post (AP) postcodes and Australian Bureau of Statistics (ABS) derived postal areas — which are an approximation of the former based on aggregated census collection districts (CDs). A group of adjacent ABS postal areas in northwest Melbourne was compared with the true AP postcode areas they purported to represent and the discrepancies were investigated. Firstly, shape mismatches were studied and their potential impacts upon resource allocation decisions were assessed. Next, comparisons of areas were undertaken. It was found that, in established inner city urban areas, the two sets of boundaries were highly correlated. However, outer suburban neighborhoods were identified as being particularly prone to major areal discrepancies. The implications of mismatches between these two key boundary data sources may be severe, given that management decisions and the allocation of public and private resources are often based on spatial statistical analyses which use these data sets. The authors acknowledge ABS efforts in providing information at the levels of aggregation that society demands. The introduction of ABS postal areas data has undoubtedly facilitated the use of demographic data in many sectors; it has, however, also caused some problems, for instance, when users assume that ABS postal areas are identical to AP postcodes. These issues could easily be avoided with the inclusion of more comprehensive metadata documentation accompanying ABS data. Research is continuing to develop a method by which agencies may derive common boundaries for their administrative units, yet still meet their own individual data and sampling requirements.     

清代京杭大运河全图初探

本文将收集到的国内外清代京杭大运河全圈作为史料处理,结合相关文献一一解读各幅运河图本身蕴涵的信息。在此基础上,挖掘出清代在绘制运河全图时常用的一些绘制手法,井就运河图的载体、装订形式加以分析。进而根据绘制风格等的差异,将清代运河全图的绘制划分为前期和后舰又依据用途和内容的不同,划分为运河河工图、漕运图、运河泉源圈和运河景观图四种。作者试图通过分析论证,挖掘出地图的史料价值,找到一个利用地图学视角观察社会历史景观的路径。     

论堆子岭文化

堆子岭化以湖南湘潭县堆子岭遗址为代表,是湘江流域新石器化谱系一个重要的组成部分。堆子岭化以红陶系为主要特征,纹饰复杂,器形以三足器为主,另有圜底器与圈足器。该化可分四期,各期有相应的承袭关系及自身特点。从其特征及源流分析,堆子岭化的来源既有本土因素,也有外来因素。洞庭湖区及汉东皖西南地区的史前化均对其有一定程度的影响。堆子岭化的消失与整个长江中游的史前化变迁有关。
