Development of Large-Scale Land Information System (LIS) by Using Geographic Information System (GIS) and Field Surveying

Cadastral maps are an important component of land administration in most countries. In virtually all developed countries, the needs of computerized land and geographic information systems (LIS/GIS) has given urgent impetus to computerizing cadastral maps and creating digital cadastral data bases (DCDB). This process is creating many institutional, legal, technical and administrative problems. This desire to establish DCDBs is being given increased impetus due to a new range of enabling technologies such as satellite position fixing (GPS), improved spatial data collection techniques such as digital theodolites and “soft copy” photogrammetry, as well as a vast range of new information and communications technological tools, thus contributing to the advancement and keeping up with the great countries. This paper presents the problem of cadastral maps. The hitherto existing cadastre, consisting of paper maps and land registers, is now becoming insufficient. Its shortcomings force developments leading to its improvement. One of the ways is the creation of a Land Information System. A digital cadastral map is the main component of this system. The structure and information content of the map is presented, its differences from analogue maps are shown, and the process of map creation is described. A digital cadastral map can be the basis for additional thematic layers, successively converting it into a complex system for management of administrative units.

Application of Geographic Information Systems in Studying the Relationship between Stock Routes Changes with Water and Pasture Availability for Livestock under a Changing Climate Conditions： A Case of Ilemela and Magu Districts in Mwanza Region-Lake Victoria Basin, Tanzania

Beef cattle production is declining in the areas surrounding LVB （Lake Victoria Basin） due to many factors among which is the climate change. This study was focused on generating spatial knowledge that will be useful in designing appropriate strategies for improving beef cattle production on rangelands of the LVB, through assessing changes in stock routes in relation to water and pasture availability for livestock under a changing climate. The study used participatory mapping and focused group discussions to assess spatial changes of stock routes in relation to water availability and pasture under critical climate changes. Also, GIS （Geographic Information Systems） technologies were deployed in formalization of spatial layers for integration with other pertinent datasets to the facilitate analysis. The study revealed remarkable stock routes changes （i.e. some have been lost, some have been converted into roads, while others have been lost and others narrowed influencing conflicts between pastorists and farmers. The stock routes changes are made by the increased human population which has led to an increase of cultivated areas and subsequently the decline of water sources and grazing land for pastorists. It is recommended that there should be effective land use planning practice, real-time stock route modification concomitant with adverse climate changes and cattle farming practice. Intervention by other mitigation measures particuticularly rainwater harvesting which is a strategy for alleviation of climate change effects for improving beef cattle production in LVB areas is proposed.

Accuracy and utility of the Structure Sensor for collecting 3D indoor information

This paper presents the result of an investigation into the utility of the Structure Sensor developed by Occipital Inc.and accuracy of its output for 3D surveying of interiors of buildings in relation to Surveying(Cadastral Survey)Regulation 2005 in Victoria,Australia.The paper investigates data acquisition issues,defines guidelines to obtain the best reconstruction result,and evaluates the result against the requirements set by the Regulation.The findings suggest a mixed result.The sensor delivers more accurate outputs for the smaller room sizes.Also,the accuracy does not meet the requirements,but it was found to be close to what is expected in the Regulation.Finally,the paper argues that the device is user-friendly enough to be used by non-experts for crowdsourcing indoor information and,the accuracy of its output can meet the needs of other domains such as indoor navigation and public safety.

Developing High-Precision Maps for Automated Driving in China:Legal Obstacles and the Way to Overcome Them

A high-precision map(HPM)is the key infrastructure to realizing the function of automated driving(AD)and ensuring its safety.However,the current laws and regulations on HPMs in China can lead to serious legal compliance problems.Thus,proper measures should be taken to remove these barriers.Starting with a complete view of the current legal obstacles to HPMs in China,this study first explains why these legal obstacles exist and the types of legal interests they are trying to protect.It then analyzes whether new technology could be used as an alternative to resolve these concerns.Factors such as national security,AD industry needs,and personal data protection,as well as the flexibility of applying technology,are discussed and analyzed hierarchically for this purpose.This study proposes that China should adhere to national security and AD industry development,pass new technical regulations that redefine the scope of national security regarding geographic information in the field of HPMs,and establish a national platform under the guidance and monitoring of the government to integrate scattered resources and promote the development of HPMs via crowdsourcing.Regarding the legal obstacles with higher technical plasticity,priority should be given to technical solutions such as“available but invisible”technology.Compared with the previous research,this study reveals the current legal barriers in China that have different levels of relevance to national security and different technical plasticity.It also proposes original measures to remove them,such as coordinating national security with the development of the AD industry,reshaping the boundary of national security and industrial interests,and giving priority to technical solutions for legal barriers that have strong technical plasticity.
