车行四千载

在山东济青高速公路临淄段上,地面上的汽车在川流不息地疾驶而过,而路旁的地下,一辆辆古代马车却在泥土中屹立着,侧卧的马匹依然昂首向前,似乎一直在等待着主人的召唤。直到二千多年后的二十世纪末,这些车辆和马匹才又重见天日,人们在修建高速公路时找到了它们。尽管一条平坦宽阔的大道展现面前,它们却再也无法上路了。于是人们在遗址上修建了古车博物馆,让这些车辆和马匹作为历史的见证,守望路旁。     

印象成都

有人说,成都有四多,美食多,美女多,茶馆多,美景多。在这里,吃喝玩乐,在这里,休闲是一种生活的状态。 在成都,那大大小小的街道,到处都有可口的美食,在那不起眼的苍蝇馆子（小饭馆）门口,你会发现有许多好车停在门前。

面向数字中国建设中国的现代大地测量基准

在回顾我国大地测量基准建设历史的基础上,分析了在当前建设信息化社会,创建数字中国,对现代地理空间基础框架中测绘基准的需求。提出了在我国建设现代大地测量基准的建议。在平面基准方面,建议在国家GPS2000网(三网)的基础上,进一步加密国家GPS网点和永久性追踪站,构建有足够分布密度的三维高精度动态大地坐标框架,为我国今后建立新的大地坐标系统创造条件。在高程基准方面,建议在仪器设备和规范细则方面作好准备工作,依法定期对国家高程控制网进行复测。在重力基准方面,在国家2000重力基准网和国家2000(似)大地水准面的基础上,有步骤的按省或地区推算具有厘米级精度,10km级栅格分辨率的似大地水准面。在条件成熟时,我国应考虑采用三维地心坐标系统。     

希腊：文明的兴衰之地

地中海几乎是一个内海,适宜于古代商船的航行,加上温暖的天气,这·才产生了欧洲历史上第一个伟大的文明——希腊文明,由此引发了“古典的地中海”的昌盛。后来,这一文明（在克服了微寒的气候以后）又延伸到了“北方的地中海”,即波罗的海、北海和拉什芒海峡（英吉利海峡）,并且在十九世纪末二十世纪初随着航海技术的改进进一步发展成为了“大西洋文明”。而在东方,在中国海的右侧,在日本和台湾、菲律宾之间的海面上,

The UK land cover map 2000: Planning,construction and calibration of a remotely sensed,user-oriented map of broad habitats

Land cover map 2000 (LCM2000) is a comprehensive survey of UK broad habitats giving vector digital maps from segment-based classification of remotely sensed satellite data. This paper examines the influence of users in designing LCM2000 and the difficulties in applying a user-defined classification. It assesses problems and successes through comparisons with a sample-based field survey. These suggest that LCM2000 accuracy at broad habitat level may be around 80–85%; however, it was not possible fully to discriminate errors in LCM2000 from those of the field survey or from mismatches in scales, resolutions and survey dates. Calibration generated broad habitat cover statistics from LCM2000 data to field survey equivalence. These take full account of the heterogeneity of a study area, helping to generate accurate statistics, including those at local level where the field survey cannot operate effectively. The paper concludes that the comprehensive and extensive coverage from remote sensing comes closer than alternative methods to meeting users needs. However, it recognises that producers of remotely sensed information need to understand better the needs of users, and users need to appreciate what the technology can and cannot deliver. This paper adds some benefits of hindsight to the process of communication.

Using CORINE land cover and the point survey LUCAS for area estimation

CORINE land cover 2000 (CLC2000) is a European land cover map produced by photo-interpretation of Landsat ETM+ images. Its direct use for area estimation can be strongly biased and does not generally report single crops. CLC areas need to be calibrated to give acceptable statistical results.LUCAS (land use/cover area frame survey) is a point survey carried out in 2001 and 2003 in the European Union (EU15) on a systematic sample of clusters of points. LUCAS is especially useful for area estimation in geographic units that do not coincide with administrative regions, such as set of coastal areas defined with a 10 km buffer. Some variance estimation issues with systematic sampling of clusters are analysed.The contingency table obtained overlaying CLC and LUCAS gives the fine scale composition of CLC classes. Using CLC for post-stratification of LUCAS is equivalent to the direct calibration estimator when the sampling units are points. Stratification is easier to adapt to a scheme in which the sampling units are the clusters of points used in LUCAS 2001/2003.

土地质量数据在土地统计中的应用

在现行的土地统计制度中 ,土地统计指标大多使用的是土地调查及土地登记的数据 ,而较少使用土地质量方面的数据。这就使得土地统计数据只能反映土地的数量和利用类别现状 ,而不能综合地反映土地的数量、质量、利用类别的实际情况。文中以土地分等定级为前提 ,提出一种将土地质量等级量化为权重的构想。同时设计一种质量权面积指标以加强土地质量因素在土地统计中的利用 ,并举例说明具体设计及实施方法。     

Updating the Phase 1 habitat map of Wales, UK, using satellite sensor data

The Phase 1 Survey is the most comprehensive and widely used national level map of semi-natural habitats in Wales. However, the survey was based largely on field survey and was conducted over several decades, before being completed in 1997. Given that resources for a repeat survey were limited, this study has used an object-orientated rule-based classification implemented within eCognition of multi-temporal satellite sensor data acquired between 2003 and 2006 to map semi-natural habitats and agricultural land across Wales, thereby allowing a progressive update of the Phase 1 Survey. The classification of objects to Phase 1 habitat classes was undertaken in two steps; firstly the landscape of Wales was divided into objects using orthorectified SPOT-5 High Resolution Geometric (HRG) reflectance data (10 m spatial resolution) and Land Parcel Information System (LPIS) boundaries. A rule-base was then developed to progressively discriminate and map the distribution of 105 sub-habitats across Wales based on time-series of SPOT HRG, Terra-1 Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Indian Remote Sensing Satellite (IRS) LISS-3 data, derived datasets (e.g., vegetation indices, fractional images) and ancillary information (e.g., topography). The rules coupled knowledge of ecology and the information content of these remote sensing data using a combination of thresholds, Boolean operations and fuzzy membership functions. A second rule-base was then developed to translate the more detailed sub-habitat classification to Phase 1 habitat classes. Indicative accuracies of the revised Phase 1 mapping, based on comparisons with the later Phase 2 survey (for selected habitats), were >80% overall and typically between 70% and 90% for many classes. Through this exercise, Wales has become the first country in Europe to produce a national map of habitats (as opposed to land cover) through object-orientated classification of satellite sensor data. Furthermore, the approach can be adapted to allow continual monitoring of the extent and condition of habitats and agricultural land.
