<p><strong>Abstract.</strong> Since its establishment in 1807, the National Oceanic and Atmospheric Administration’s (NOAA) Office of Coast Survey has provided nautical charts to support safe shipping, national defence, and the delamination of maritime boundaries. The mission of the office is to provide navigation products and services that ensure safe and efficient maritime commerce on America’s oceans and coastal waters, and in the Great Lakes. The Office of Coast Survey employs cartographers, hydrographers, physical scientists, managers and administrative staff in order to fulfil its mission. Until recently, training in nautical cartography at the office of Coast Survey was conducted at the branch level and differed based on level of employee seniority (i.e., Entry, Intermediate and Advanced) and the processing branch of the employee. Over the past two years, NOAA has established a Coast Survey CAT B program that is intended to train and educate to up to 13 cartographers per year in nautical cartography, through a combination of lectures, hands-on chart production experience, details to various branches within the Coast Survey, and field trips to working hydrographic survey vessels through six training modules spread over a one-year period, spread over six courses that include:</p><ul><li><i>Refresher course</i> that provides a review of the basic math, computer and communication technology, marine geography, hydrography, and geodetic topics. The goal of this course is to ensure that students have a sufficient academic background to succeed in the subsequent CAT-B program courses and other activities.</li><li><i>Introduction to Cartography course</i> that reviews elements of cartography, specifically scale, design, and data manipulation techniques. Students will gain an appreciation for maps and map-making, including manual techniques. This introductory course will include hands-on use of computer graphics tools.</li><li><i>Map Design course</i> that reviews the various styles and techniques associated with cartographic design. The course will require the student to: 1) analyse chart design parameters, 2) compile thematic cartographic projects, and 3) experiment with map design.</li><li><i>GIS and Spatial Analysis course</i> that provides students with a comprehensive understanding of spatial analysis methods and they will learn practical skills in using GIS and spatial analysis. The class covers the methods of spatial analysis including measuring aspects of geometric features and identifying spatial patterns of geospatial objects that are represented as point, line, network, areal data, and 3-D surfaces.</li><li><i>GIS and Spatial Modelling course</i> that provides the students a foundation and understanding of various issues related to modelling and simulation in the GIS. It will address the concepts, tools, and techniques of GIS modelling (vector- and raster-based modelling). In addition, it will present modelling concepts and theory as well as provide opportunities for hands-on model design, construction, and application.</li><li><i>NOAA training project and internship program course</i> that includes: 1) a detailed review of many of the activities conducted by the branches in NOAA’s Marine Chart Division and 2) a training project that demonstrates the student’s ability to implement the knowledge gained during the certification.</li></ul><p>This paper presents a newly established CAT B certificate program in Standards of Competence for Nautical Cartographers that is conducted at NOAA’s main campus in Silver Spring, Maryland, USA. The CAT B certificate program provides NOAA a mechanism to both enhance building capacity within the organization and recognizing NOAA cartographers for their capabilities and efforts. In addition, such a program at NOAA can also be used to recruit new employees and help to build capacity in sister organizations.</p>

Cognitive Retention

Undergraduate students pursuing a Bachelor of Science in Forestry (BSF) at Stephen F. Austin State University (SFA) within the Arthur Temple College of Forestry and Agriculture (ATCOFA) attend an intensive 6-week hands-on instruction in applied field methods. The second week of field station is focused on land measurement activities to introduce students to practical, hands-on, and technology based ways to survey forest boundaries. On Monday of the second week students are introduced to the concepts of how to use a handheld compass to navigate from point to point, use a consumer-grade handheld Global Positioning System (GPS) unit for collecting the geographic coordinates of given locations, use a GPS unit to calculate the area of a forest opening, use a GPS unit to walk and record a forest hiking trail, and evaluate the accuracy of their GPS derived locations via a Root Mean Square Error (RMSE) analysis. RMSE analysis between a students collected geographic coordinates and the instructors collected geographic coordinates indicated that the students were sufficient in correctly recording the geographic coordinates of point, line, and polygon features identified in the field. Grades on the student submitted reports summarizing Monday’s activities resulted in 33 of 56 students (59.0%) receiving a high A, 14 of 56 students (25.0%) receiving a low A, and 9 of 56 students (16.0%) receiving a high B indicating that the interactive hands-on nature of ATCOFA’s field station is effective at providing students with real-world applications whereby they will be ready to make a difference the day after graduation. Interactive drone imagery and video integrated into the daily activities in the field to enhance a student’s understanding of their specific objectives provided the students in the field with a bird’s eye perspective of the landscape to aid their understanding and planning of the field tasks assigned. In conclusion, employers can have confidence that when hiring recent BSF graduates from ATCOFA that the students have been introduced to geospatial technologies within a proven one-on-one instruction methodology designed to increase cognitive retention and can traverse from location to location accurately and record the geographic coordinates of earth surface features correctly.

Modeling Distance and Direction Relationships (DDR) is a key issue in spatial analysis and spatial reasoning. Various fields such as geology, hydrology, ecology, etc. apply DDR models to help digging out valuable patterns hidden in geoscientific dataset. This paper proposed two quantitative models through a raster-based approach for computing Euclidean distance and cardinal direction relationships, respectively, between a pair of spatial objects in a two-dimensional geographical space. The corresponding algorithms were designed and implemented. This new raster-based modeling can work universally on all types of spatial objects (point, line, polygon, or compound objects) and quantify DDR more accurately due to its sensitivity to object shapes. The usefulness of the modeling was demonstrated by various applications.

The use of geographic information systems (GIS) is widespread in water resources management. One of the development stages in this area was the use of GIS information not only for matching and executing queries, but also for analyzing trends and making decisions using applications that provide spatial analysis. GIS provides the ability to process spatial information and represent it using a similar reality model that represents spatial features from a point, line, and polygon, and thematic information. Spatial analysis in GIS includes a set of procedures used to study the structure and territorial relations based on knowledge of the position and characteristics of geographical features of the corresponding variables. Subject: delineation of areas for potential location of dams with the use of geospatial algorithms for distance. The research is based on the hypothesis that from geospatial analysis of the distances between peaks extracted from the .shp layers of rivers and areas of great importance for protection, it is possible to delineate potential areas for dam construction. Materials and methods: literature sources and results of preliminary experimental studies are analyzed, experimental planning is carried out. Results: This study examines the use of algorithms for processing distances between points used in the field of service geography, in connection with the use of localization and distribution models. To do this, algorithms are compared using criteria such as processing time, the ability to create new layers, and creating tables of distances between objects belonging to different layers. Conclusions: This evaluation is performed in order to select the most appropriate algorithm for selecting suitable points that can be evaluated in future analysis of localization and dam construction.

Tolerance specification involves selecting tolerance types for functional or assembly features to control the variation of features. General methods tend to formulate a frame to specify all the features of part, while the specification methods or reasoning rules for specific feature (point, line, plane, cylinder, etc.) are less studied. This paper focuses on the tolerance-type selection of the plane feature. The theory of axiomatic design is introduced to select the tolerance type for the plane feature, and the problem is interpreted as a redundant decoupled design. To achieve the functional requirements, design parameters and constraints of physics domain are determined. The mapping rules, which are between design parameters and functional requirements, are generated based on the independent axiom. Considering the large number of solutions of the design, the constraints such as cost and inspection methods are introduced to reduce the number of solutions. The minimum information axiom is introduced for the optimum mapping rules and the tolerance types are selected by the optimum mapping rules for the plane feature. Finally, the specification process is concluded and demonstrated by means of an example.

The authors aim to provide a review of the potential for the application of GIS and spatial-modelling techniques in the context of educational planning. It is their contention that such techniques can be particularly effective given the recent changes in the education-policy framework; namely the development of a market system to replace the previous, producer-led, planning environment. The authors argue that GIS-based techniques can offer only a partial solution to the manifold problems facing educationalists, and that we must look to more advanced spatial-analysis tools such as spatial-interaction modelling. The authors conclude that a combination of these techniques offers a powerful tool for planners who are increasingly concerned with questions of the equity of provision.

Lombok Barat is one of the districts on the island of Lombok and became a tourist destination, has the appeal of natural and cultural tourism. Conditions natural attractions consist of naturallandscapes, protected forests and community forests, beaches, plantations, and the diversity of marine potential. One element of the plantation sector which is currently untapped optimally is an agro-tourism. Agro-tourism potential is addressed from the natural beauty of the plantation and production in the plantation sector is sufficiently developed. Geographical Information Systems produces data aspects of spatial and non-spatial data. The main characteristics of the geographic information system is the ability to analyze a system such as statistical analysis and overlay called spatial analysis by adding the dimension '(space)' or geography. Spatial analysis conducted with mengoverlay two maps which then generates a new map analysis results. Spatial analysis process includes activities to create a buffer around a point (point), line (line) and area (polygon), analyzing a map with points, lines and areas with the overlay method, intersection, union, identity, and clips.  Based on the spatial analysis has been done it obtained the three locations that can be used for agro tourism, namely: a coffee plantation with an area of 9751995 m2, oil plantation area of 8.99343 million and 27.03261 million, vanilla and coffee plantations covering an area of 7,042,943 m2.

Environmental degradation and increasing risks to regional eco-systems seriously impede the progress towards sustainable development goals. This study is aimed at investigating the spatial aspect of this problem by focusing on the case of Russia, in particular the environmental aspects of the country's spatial organization. Methodologically, the study relies on spatial analysis methods (spatial modelling and mapping) and the official statistical data. As a result, we have identified heavily polluted locations that jeopardize sustainable development efforts on the national level: as these locations are situated in close proximity to each other and share a strong spatial correlation, their combined impact far exceeds that of isolated territories. It was found that Siberia is the largest zone of concentration of air pollution hotspots, where high levels of air pollution are not compensated for by these regions’ outstanding economic performance. Our findings have shown that the patterns of the country's economic and environmental spatial organization do not always coincide. In other words, the regions with booming economies are not always the same regions whose manufacturing sector puts the heaviest pressure on the environment. This can point to the fact that the link between economic activities and environmental pressures is now weakening.

Improve Instruction

The Materials Science Department at Iowa State University has developed a laboratory designed to improve instruction in the use of the scanning electron microscope (SEM). The laboratory makes use of a computer network and a series of remote workstations in a classroom setting to provide students with increased hands-on access to the SEM. The laboratory has also been equipped such that distance learning via the internet can be achieved.A view of the laboratory is shown in Figure 1. The laboratory consists of a JEOL 6100 SEM, a Macintosh Quadra computer that acts as a server for the network and controls the energy dispersive spectrometer (EDS), four Macintosh computers that act as remote workstations, and a fifth Macintosh that acts as an internet server. A schematic layout of the classroom is shown in Figure 2. The workstations are connected directly to the SEM to allow joystick and computer control of the microscope. An ethernet connection between the Quadra and the workstations allows students seated there to operate the EDS. Control of the microscope and joystick is passed between the workstations by a switch-box assembly that resides at the microscope console. When the switch-box assembly is activated a direct serial line is established between the specified workstation and the microscope via the SEM’s RS-232.

Fundamental Limitation

The confocal microscope is now widely used in both biomedical and industrial applications for imaging, in three dimensions, objects with appreciable depth. There are now a range of different microscopes on the market, which have adopted a variety of different designs. The aim of this paper is to explore the effects on imaging performance of design parameters including the method of scanning, the type of detector, and the size and shape of the confocal aperture.It is becoming apparent that there is no such thing as an ideal confocal microscope: all systems have limitations and the best compromise depends on what the microscope is used for and how it is used. The most important compromise at present is between image quality and speed of scanning, which is particularly apparent when imaging with very weak signals. If great speed is not of importance, then the fundamental limitation for fluorescence imaging is the detection of sufficient numbers of photons before the fluorochrome bleaches.

Teaching Learning

Promoting cultural competence in serving diverse clients has become critically important across disciplines. Yet, progress has been limited in raising awareness and sensitivity. Tervalon and Murray-Garcia (1998) believed that cultural competence can only be truly achieved through critical self-assessment, recognition of limits, and ongoing acquisition of knowledge (known as “cultural humility”). Teaching cultural humility, and the value associated with it remains a challenging task for many educators. Challenges inherent in such instruction stem from lack of resources/known strategies as well as learner and instructor readiness. Kirk (2007) further indicates that providing feedback on one's integrity could be threatening. In current study, both traditional classroom-based teaching pedagogy and hands-on community engagement were reviewed. To bridge a gap between academic teaching/learning and real world situations, the author proposed service learning as a means to teach cultural humility and empower students with confidence in serving clients from culturally/linguistically diverse backgrounds. To provide a class of 51 students with multicultural and multilingual community service experience, the author partnered with the Tzu-Chi Foundation (an international nonprofit organization). In this article, the results, strengths, and limitations of this service learning project are discussed.
