(Geospatial) Data by Mihal Miu ATHABASCA UNIVERSITY AGGREGATION OF MAP (GEOSPATIAL) DATA BY MIHAL MIU An integration project submitted in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE in INFORMATION SYSTEMS Athabasca, Alberta April 2015 © Mihal Miu, 2015, 2016 Abstract: Aggregation and fusion of geospatial data using a virtual globe implemented as a GIS application named PlaniSphere developed by the author. Geospatial data can be obtained from public suppliers as well as from commercial vendors. Commercial vendors and open-source suppliers focus on different details of information and use a variety of file formats that can be restrictive in their usage. To widen usage aggregation and fusion of geospatial data obtained from different sources can be used to generate a new 3D/2D map or an enhanced 3D/2D map using geospatial data from existing sources. The new or enhanced 3D/2D map has the potential to be used in land analysis, land resource management, city planning, agriculture, forestry, and orbital analysis of objects.

................................................................................................................................................ 119 Background Problem/Opportunity Currently there is no geographic information system (GIS) service that allows aggregating and fusion of geospatial data from different data sources. Investigation showed that existing GISs are limited in scope. If multiple map services for geographically distinct regions could be aggregated then the end result would be a map with greater coverage or a new map. If multiple map services for the same geographical region could be aggregated than the resulting map produced would be an enhanced map. Investigation showed that current GIS commercial vendors are closed-source and will direct or encourage users to use geospatial data from their own sources or their preferred vendors. ESRI through its ArcGIS platform creates a GIS infrastructure and provides users with servers, clients, and geospatial data. ArcGIS has a plug-in infrastructure that allows users to perform their own customization, however restrictive. Another example is Google Earth. Google provides users with a desktop client that uses geospatial data hosted on Google’s servers/server farms. Google Earth does not allow for user customization and it has no plug-in infrastructure. Existing GIS vendors provide

  • Analyze a World Map
    Analyze a World Map Materials: Map of the World: Political or use link this website Map of the World Worksheet You could start the discussion by saying that the social studies part of the GED test assumes that everyone has a basic knowledge of world geography. The test will contain maps that you have to analyze and the answers are not always directly on the map. This is one area of the test where they expect you to just know the approximate locations of countries and oceans. So we thought we would use this world map to familiarize everyone with some world geography. Hand out the maps. The first thing you need to do with a map is read the title so that you know what you are looking at. Ask, “What is the title of this map?” ‘Map of the World: Political”. So this map should give us information about the location of countries. Then look to see if there is a legend or a list of symbols that explains the information shown on the map. Ask, “Is there a legend for this map/” Yes, it shows the scale of the map. You can discuss that the scale shows the relationship between distances on the map to the actual distance on the ground. Look to see if there is anything on the map showing directions, most maps have a compass that shows east, west, north, and south. Ask, “Does this map have any symbols indicating direction?” Yes, this map has a direction compass that shows points north. Ask if students know where south, east, and west are on the map.

Objectives of work Scope/Previous Results:Virtual Globes can attract and inform websites visitors on natural and cultural objects and sceneries.Geo-centered information transfer is suitable for majority of sites and artifacts. Virtual Globes have been tested with an involvement of TUD institutes: e.g. the GEPAM project (Weller,2013), and an archaeological excavation site in the Altai Mountains ("Uch enmek", c.f. Schmid 2012, Schubert 2014).Virtual Globes technology should be flexible in terms of the desired geo-data configuration. Research data should be controlled by the authors. Modes of linking geo-objects to different types of meta-information seems evenly important for a successful deployment. Motivation: For an archaeological conservation site ("Uch Enmek") effort has already been directed into data collection, model development and an initial web-based presentation.The present "Open Web Globe" technology is not developed any further, what calls for a migra- tion into a different web environment.

  • Earth's Structure and Processes 8-3 the Student Will Demonstrate An
    Earth’s Structure and Processes 8-3 The student will demonstrate an understanding of materials that determine the structure of Earth and the processes that have altered this structure. (Earth Science) 8-3.1 Summarize the three layers of Earth – crust, mantle, and core – on the basis of relative position, density, and composition. Taxonomy level: 2.4-B Understand Conceptual Knowledge Previous/future knowledge: Students in 3rd grade (3-3.5, 3-3.6) focused on Earth’s surface features, water, and land. In 5th grade (5-3.2), students illustrated Earth’s ocean floor. The physical property of density was introduced in 7th grade (7-5.9). Students have not been introduced to areas of Earth below the surface. Further study into Earth’s internal structure based on internal heat and gravitational energy is part of the content of high school Earth Science (ES-3.2). It is essential for students to know that Earth has layers that have specific conditions and composition. Layer Relative Position Density Composition Crust Outermost layer; thinnest Least dense layer overall; Solid rock – mostly under the ocean, thickest Oceanic crust (basalt) is silicon and oxygen under continents; crust & more dense than Oceanic crust - basalt; top of mantle called the continental crust (granite) Continental crust - granite lithosphere Mantle Middle layer, thickest Density increases with Hot softened rock; layer; top portion called depth because of contains iron and the asthenosphere increasing pressure magnesium Core Inner layer; consists of Heaviest material; most Mostly iron and nickel; two parts – outer core and dense layer outer core – slow flowing inner core liquid, inner core - solid It is not essential for students to know specific depths or temperatures of the layers.

  • Evaluation of Tandem-X Dems on Selected Brazilian Sites: Comparison with SRTM, ASTER GDEM and ALOS AW3D30
    Cite as: Grohmann, C.H., 2018. Evaluation of TanDEM-X DEMs on selected Brazilian sites: comparison with SRTM, ASTER GDEM and ALOS AW3D30. Remote Sensing of Environment. 212:121-133. doi:10.1016/j.rse.2018.04.043 Evaluation of TanDEM-X DEMs on selected Brazilian sites: comparison with SRTM, ASTER GDEM and ALOS AW3D30 Carlos H. Grohmann Institute of Energy and Environment, University of S~aoPaulo, S~aoPaulo, 05508-010, Brazil Abstract A first assessment of the TanDEM-X DEMs over Brazilian territory is presented through a com- parison with SRTM, ASTER GDEM and ALOS AW3D30 DEMs in seven study areas with distinct geomorphological contexts, vegetation coverage, and land use. Visual analysis and elevation his- tograms point to a finer effective spatial (i.e., horizontal) resolution of TanDEM-X compared to SRTM and ASTER GDEM. In areas of open vegetation, TanDEM-X lower elevations indicate a deeper penetration of the radar signal. DEMs of differences (DoDs) allowed the identification of issues inherent to the production methods of the analyzed DEMs, such as mast oscillations in SRTM data and mismatch between adjacent scenes in ASTER GDEM and ALOS AW3D30. A systematic difference in elevations between TanDEM-X 12 m, TanDEM-X 30 m, and SRTM was observed in the steep slopes of the coastal ranges, related to the moving-window process used to resample the 12 m data to a 30 m pixel size. It is strongly recommended to produce a DoD with SRTM before using ASTER GDEM or ALOS AW3D30 in any analysis, to evaluate if the area of interest is affected by these problems.

  • World Map of Al-‘Umari #226.1
    World Map of al-‘Umari #226.1 TITLE: The Mamunic World Map DATE: 1340 AUTHOR: Ahmad ibn Yahya ibn Fadlallah al-‘Umari DESCRIPTION: The geographic work Masalik al-aNar fi mainalik al-amsar [Ways of Perception Concerning the Most Populous [Civilized] Provinces] was written by Ahmad Ibn Fadlalldh al-Umari (died 1349), a distinguished administrator and author who was active in Cairo and Damascus under Mamluk rule. He claims that the map is a copy of the world map made for Caliph al-Ma’mun (reigned 813-833); also mentioned by al-Mas’udi (#212) earlier. The world map shown here is reproduced in this manuscript of the work of al- ‘Umari. The same manuscript also has maps of the first three climates. Although the climates are not divided into sections, the general impression is that the maps are derived from those of al-Idrisi (#219). However, from its appearance it seems to have been compiled from the text of the Kitab bast al-ard fi tuliha wa-al-‘ard [Exposition of the earth in length and breadth] by Ibn Sa‘id (#221). Al-‘Umari’s text does mention a map and gives a few examples of longitude and latitude, but on the whole they do not correspond with positions given on the map. Most of the Istanbul manuscripts of Ibn Fadlallah al-‘Umari’s work are undated. However, the earliest one to be dated is 1585, suggesting that this and most other copies were prepared for the libraries of the Ottoman sultans of that period. By that time the idea of a graticule was well known from European sources and could have been added to bring the map up to date.

  • Geoscience Data for Educational Use: Recommendations from Scientific/Technical and Educational Communities Michael R
    JOURNAL OF GEOSCIENCE EDUCATION 60, 249–256 (2012) Geoscience Data for Educational Use: Recommendations from Scientific/Technical and Educational Communities Michael R. Taber,1,a Tamara Shapiro Ledley,2 Susan Lynds,3 Ben Domenico,4 and LuAnn Dahlman5 ABSTRACT Access to geoscience data has been difficult for many educators. Understanding what educators want in terms of data has been equally difficult for scientists. From 2004 to 2009, we conducted annual workshops that brought together scientists, data providers, data analysis tool specialists, educators, and curriculum developers to better understand data use, access, and user- community needs. All users desired more access to data that provide an opportunity to conduct queries, as well as visual/ graphical displays on geoscience data without the barriers presented by specialized data formats or software knowledge. Presented here is a framework for examining data access from a workflow perspective, a redefinition of data not as products but as learning opportunities, and finally, results from a Data Use Survey collected during six workshops that indicate a preference for easy-to-obtain data that allow users to graph, map, and recognize patterns using educationally familiar tools (e.g., Excel and Google Earth).

  • Comparison of Spherical Cube Map Projections Used in Planet-Sized Terrain Rendering
    FACTA UNIVERSITATIS (NIS)ˇ Ser. Math. Inform. Vol. 31, No 2 (2016), 259–297 COMPARISON OF SPHERICAL CUBE MAP PROJECTIONS USED IN PLANET-SIZED TERRAIN RENDERING Aleksandar M. Dimitrijevi´c, Martin Lambers and Dejan D. Ranˇci´c Abstract. A wide variety of projections from a planet surface to a two-dimensional map are known, and the correct choice of a particular projection for a given application area depends on many factors. In the computer graphics domain, in particular in the field of planet rendering systems, the importance of that choice has been neglected so far and inadequate criteria have been used to select a projection. In this paper, we derive evaluation criteria, based on texture distortion, suitable for this application domain, and apply them to a comprehensive list of spherical cube map projections to demonstrate their properties. Keywords: Map projection, spherical cube, distortion, texturing, graphics 1. Introduction Map projections have been used for centuries to represent the curved surface of the Earth with a two-dimensional map. A wide variety of map projections have been proposed, each with different properties. Of particular interest are scale variations and angular distortions introduced by map projections – since the spheroidal surface is not developable, a projection onto a plane cannot be both conformal (angle- preserving) and equal-area (constant-scale) at the same time. These two properties are usually analyzed using Tissot’s indicatrix. An overview of map projections and an introduction to Tissot’s indicatrix are given by Snyder [24]. In computer graphics, a map projection is a central part of systems that render planets or similar celestial bodies: the surface properties (photos, digital elevation models, radar imagery, thermal measurements, etc.) are stored in a map hierarchy in different resolutions.
