Cơ sở hạ tầng dữ liệu không gian: Chính sách, giá trị, và chi phí lợi ích Giới thiệu về chính sách trong cơ sở hạ tầng dữ liệu không gian Trong số các vấn đề chính sách quan trọng ảnh hưởng đến thông tin địa lý (GI) trên toàn cầu là thông tin sở hữu, giám hộ, và bảo quản, truy cập và quyền khai thác và chế độ sạc thông tin khu vực công (PSI). Một số những vấn đề này đã được kiểm tra trong các chương trước đó. Trong chương này, chúng tôi khám phá vai trò của. | chapter six Spatial data infrastructures Policy value and cost-benefit Introduction to policy in spatial data infrastructure Among the key policy issues affecting geographic information GI globally are information ownership custodianship and preservation access and exploitation rights and charging regimes for public sector information PSI . Some of these issues were examined in earlier chapters. In this chapter we explore the role of geographic information policies and their implementation strategies within spatial data infrastructure SDI and under the umbrella framework of national information infrastructure NII . In doing so we revisit the concepts of value of GI and how the many values identified in Chapter 2 affect infrastructure-wide impact assessments or cost-benefit analyses for SDI implementations. Following the practice of earlier chapters we begin at the elementary level of defining some basic terms such as policy information policy and strategy and then present a sample of SDI definitions to see where policy falls within these definitions. This chapter is not meant to be a compendium of SDIs that are evolving around the globe which has been the focus of several publications over the past decade Burrough and Masser 1998 Groot and McLaughlin 2000 Van Loenen and Kok 2004 Masser 2005 2007 Van Loenen 2006 Crompvoets 2006 Onsrud 2007 . Rather we present samples of SDI initiatives at the national and regional level to provide insight into how policy issues are at the heart of SDI visions goals and strategies along with other technical and organization issues where policies may have only an indirect impact. Many SDI policies are aligned to national information infrastructure NII policies inherently or on purpose since much GI is in the public sector and is the the focus of many NII initiatives including PSI reuse and e-governance. We start by asking what policies are and why have them. According to the American Heritage Dictionary a policy is a plan of .
