These technologies include three fundamental components: • Cataloguing of all available spatial and other data resources that might be relevant within an organization. This includes data stored on organized file systems in the many common formats (grids, images, raw data, and file documents), metadata stored in RDBMS systems, spatial data stored in certain RDBMS systems (such as acQuire), and data stored within corporate archiving systems. • Searching for and evaluating data that may be relevant to a project at hand. This involves spatial and context searches for data by area of interest, data type, and full metadata evaluation to determine the value of each dataset for a particular use. It also involves rapidly previewing the content of selected datasets. • Retrieval of the selected data, which is windowed to the area of interest, re-projected to an appropriate coordinate system, sampled to an appropriate scale, and transformed into a format that can be used. This also includes simple retrieval of documents and reports that support the data and can be viewed in native formats (such as .doc and .pdf files). DAP11 New Features DAP now supports the following new data types and data connectors • ESRI LYR files • ArcGIS Map Services • ArcIMS Image Services • ArcIMS Metadata Services • Relational Databases (RDBMS) • Section Grids/Images Note: ArcSDE and Personal Geodatabase Connectors are no longer supported. DAP now provides an enhanced and fully integrated metadata solution • Publishing of metadata created in Oasis montaj 7.0 and related applications • Support of FGDC and ISO19139 metadata standards, together with the introduction of Geosoft metadata schema • Graphical viewing of metadata by use of style sheets in Oasis montaj and DAP Administrator • Cataloging of metadata in XML files and synchronization of metadata in relational databases and XML files Additional enhancements in DAP Server and DAP Administrator • Distributed DAP cataloging processes – this feature is available in SP1 • Setting coordinate system and extent to datasets in a folder • Support of disclaimer/copyright at dataset level 2 0BChapter 1: DAP Server Introduction • Auto cataloging for datasets in DAP data folders • Entry of IDAP account parameters during installation of DAP server software New Features in DAP Client Plug-ins • The new Dapple client interface is now available through the ArcGIS 2.0.1 and MapInfo 7.0.1 Plug-ins Target Audience This document is intended for Geosoft DAP Administrators who are responsible for the installation and maintenance of the Geosoft DAP Server and spatial data catalogs. A Geosoft DAP Administrator may be: • A single user who wishes to create a personal DAP server for sharing data among a group of colleagues on an Intranet • A corporate database administrator responsible for archiving and disseminating large- volume geospatial data across a corporate or organizational Intranet • A database administrator at a government data distribution centre responsible for making large-volume geospatial data available to the public online This document may also be used by Web developers for building web servers that integrate Geosoft DAP data distribution technologies into a data discovery and delivery web portal. You might choose the Geosoft DAP technology to perform your data distribution task because of one or more of the following reasons: • You have large-volume data, such as large gridded data, airborne geophysical data, large georeferenced point databases or large vector maps, which you need to make available in an efficient way and with minimum data preparation costs. You may also have document files or files of other types that you would like to georeference, catalog, and distribute. • Your data can be easily organized within a file system as individual data files in a variety of formats. You want to be able to automatically catalog this file system and make the data available to your data consumers. • You have corporate data stored and managed within an acQuire Data Model on an ODBC-accessible server, and you want to make this data available to clients who need to work with this data. • Your data-consuming clients are geographically dispersed and connected to central servers only via a WAN, or perhaps even the Internet, and you need an efficient and easy way for them to find and retrieve their own data. • Your data is georeferenced in known or well-defined coordinate systems and must be converted to a user’s coordinate system as part of the data delivery process. 0BChapter 1: DAP Server Introduction 3 • Because your datasets are large, and may cover broad geographic areas, your users may only require subsets of the data to suite their purposes. You need technologies that can efficiently subset and resample data to meet your users’ needs. • A significant number of your data consumers use workstation software such as Oasis montaj, ArcGIS, and MapInfo to access and process data that you provide. You would like these users to be able to access your data directly and efficiently from these environments. • You may want to provide a web interface to your data so that your data consumers can use a web browser to discover the data you have available, and retrieve this data in a variety of formats in any projected coordinate system. • Because your datasets are large, and you may have a large number of separate datasets in different formats, you do not want to convert all your data to a single format. Your data models may be too complex to load all your data to a standard database. The Geosoft DAP Server technology addresses all the above issues (see the Technology Overview section) within certain limitations (see the Technology Limitations section). 4 0BChapter 1: DAP Server Introduction Technology Overview Geosoft DAP is a middleware server technology that connects networked users to back- end spatial data stores, which is illustrated in the following diagram. From the deployment perspective, DAP is installed on a high-performance server at your data centre, where it can be configured to have high-speed access to data stores. A simple deployment would place DAP on a server that directly hosts large disks that store data to be distributed in a file system, and relational databases for storing metadata and geochemistry data. DAP responds to XML and Geosoft TASK requests for data catalogs, data searches, metadata and actual data retrieval. Professionals who need to find and use data will use their preferred applications, such as Oasis montaj, ArcMap, MapInfo, or an acQuire API-enabled application to access data. Data can also be browsed and retrieved via a web interface. Alternatively, other applications can use Geosoft XML to deliver data to their own specific workflows. A DAP implementation requires a dedicated server in all cases, except possibly for evaluation purposes, or if DAP is deployed on a data professional’s workstation to share data among a small team. For performance reasons, DAP creates and maintains a catalog file that stores certain information about all the cataloged data, and provides for optimal browsing and searching performance. A DAP Data Administrator manages the DAP catalog through a client workstation connected directly to the DAP Server network. The DAP Data Administrator uses Geosoft Oasis montaj or ArcMap to perform the data QA/QC (Quality Assurance and Quality 0BChapter 1: DAP Server Introduction 5 Control) and certain data preparation tasks. The DAP Administrator application is used to directly manage the DAP Server and the data catalog.

PORTA-SIMD: AN OPTIMALLY PORTABLE SIMD PROGRAMMING LANGUAGE by Russell Raymond Tuck, III Department of Computer Science Duke University Dissertation submitte in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Computer Science in the Graduate School of Duke University 1990 Copyright © 1990 by Russell Raymond Tuck, III All rights reserved Abstract Existing programming languages contain architectural assumptions which limit their porta­ bility. I submit optimal portability, a new concept which solves this language design problem. Optimal portability makes it possible to design languages which are portable across vari­ ous sets of diverse architectures. SIMD (Single-Instruction stream, Multiple-Data stream) computers represent an important and very diverse set of architectures for which to demon­ strate optimal portability. Porta-SIMD (pronounced "porta.-simm'd") is the first optimally portable language for SIMD computers. It was designed and implemented to demonstrate that optimal portability is a useful and achievable standard for language design. An optimally portable language allows each program to specify the architectural features it requires. The language then enables the compiled program to exploit exactly those fea.­ tures, and to run on all architectures that provide them.

However, the Lidar performance of pushbroom DAP relative to frame-based DAP and airborne lidar is not well documented. Interest Structure from motion in DAP stems largely from its low cost relative to lidar. Studies have demonstrated that frame-based DAP Photogrammetry generally performs slightly poorer than lidar, but still provides good value due to its reduced cost. In the USA Forestry pushbroom imagery can be dramatically less expensive than frame-camera imagery in part because of a na- DAP tionwide collection program.

What is OPeNDAP OPeNDAP provides a way for researchers to access scientific data anywhere on the Internet, from a wide variety of new and existing programs. It is used widely in earth-science research settings but it is not limited to that. Using a flexible data model and a well-defined transmission format, an OPeNDAP client can request data from a wide variety of OPeNDAP servers, allowing researchers to enjoy flexibility similar to the flexibility of the web. There are different implementations of OPeNDAP produced by various open source NOTE organizations. This guide covers the implementation of OPeNDAP produced by the OPeNDAP group. The OPeNDAP architecture uses a client/server model, with a client that sends requests for data out onto the network to a server, that answers with the requested data.

The OPeNDAP group is also the original developer of the Data Access Protocol (DAP) that the software uses. Many other groups have adopted DAP and provide compatible clients, servers, and SDKs. OPeNDAP’s DAP is also a NASA community standard. For the rest of this document, "OPeNDAP" will refer to the software. With OPeNDAP, you can access data using an OPeNDAP URL of any database server that supports OPeNDAP. You can do this via command-line, Internet browser, or a custom UI. You can also use other NetCFD complaint tools, such asMatlab, R, IDL, IDV, and Panoply. Note that OPeNDAP data is, by default, stored and transmitted in binary form. In addition to its native data representation format, OPeNDAP can get data in the following formats: NetCDF, GeoTIFF, JPEG2000, JSON, ASCII. This quick start guide covers how to use OPeNDAP in a typical web browser, such as Firefox, Chrome, or Safari, to discover information about data that is useful when creating database queries.

    Developing Policy Inputs for Efficient Trade and Sustainable Development Using Data Analysis Mini.K.G Senior Scientist, Fisheries Resources Assessment Division Central Marine Fisheries Research Institute, Kochi Email: [email protected] Introduction Trade forms a vital part of the world economy. The analysis of data on trade and related parameters plays a pivotal role in developing policy inputs for efficient trade and sustainable development. It is evident that the success of any type of analysis depends on the availability of the suitable type of data. In general, time series, cross sectional and pooled data are the three types of data available for trade analysis. Time series data are characterized by observations collected at regular intervals over a period of time while cross-sectional data are data on one or more variables collected at the same point of time. The pooled data is a combination of time series and cross-sectional data. For example, panel data, which is a special type of pooled data is used to study the relationship between trade flows and trade barriers over time. In recent years, the quantitative and qualitative analysis of trade and the effects of policies have grown sharply. This was due to the advances in the theoretical and analytical techniques as well as increased computational and data processing power of computers. A multitude of analysis tools are available in today’s world for a thorough and scientifically valid analysis of data. There are several choices available for the user to choose from – ranging from the general public license packages, analysis packages with statistical add-ons, general purpose languages with statistics libraries to the advanced proprietary packages.
