Spatial 2015, Werner Kuhn, Matt Duckham, Marcia Castro
Journal of Spatial Information Science
This report summarizes the first in a new series of interdisciplinary unconferences, called SPATIAL. SPATIAL 2015 was focused on applying spatial information to human health, and was held at the Center for Spatial Studies at the University of California, Santa Barbara, 9-11 December 2015.
Spatial Refinement As Collection Order Relations, Zhong Zhao
Spatial Refinement As Collection Order Relations, Zhong Zhao
Journal of Spatial Information Science
An abstract examination of refinement (and conversely, coarsening) with respect to the involved spatial relations gives rise to formulated order relations between spatial coverings, which are defined as complete-coverage representations composed of regional granules. Coverings, which generalize partitions by allowing granules to overlap, enhance hierarchical geocomputations in several ways. Refinement between spatial coverings has underlying patterns with respect to inclusion—formalized as binary topological relations—between their granules. The patterns are captured by collection relations of inclusion, which are obtained by constraining relevant topological relations with cardinality properties such as uniqueness and totality. Conjoining relevant collection relations of equality and proper inclusion …
Routes Visualization: Automated Placement Of Multiple Route Symbols Along A Physical Network Infrastructure, Jules Teulade-Denantes, Adrien Maudet, Cécile Duchêne
Routes Visualization: Automated Placement Of Multiple Route Symbols Along A Physical Network Infrastructure, Jules Teulade-Denantes, Adrien Maudet, Cécile Duchêne
Journal of Spatial Information Science
This paper tackles the representation of routes carried by a physical network infrastructure on a map. In particular, the paper examines the case where each route is represented by a separate colored linear symbol offset from the physical network segments and from other routes---as on public transit maps with bus routes offset from roads. In this study, the objective is to automate the placement of such route symbols while maximizing their legibility, especially at junctions. The problem is modeled as a constraint optimization problem. Legibility criteria are identified and formalized as constraints to optimize, while focusing on the case of …
Invariant Spatial Information In Sketch Maps — A Study Of Survey Sketch Maps Of Urban Areas, Jia Wang, Angela Schwering
Invariant Spatial Information In Sketch Maps — A Study Of Survey Sketch Maps Of Urban Areas, Jia Wang, Angela Schwering
Journal of Spatial Information Science
It is commonly recognized that free-hand sketch maps are influenced by cognitive impacts and therefore sketch maps are incomplete, distorted, and schematized. This makes it difficult to achieve a one-to-one alignment between a sketch map and its corresponding geo-referenced metric map. Nevertheless, sketch maps are still useful to communicate spatial knowledge, indicating that sketch maps contain certain spatial information that is robust to cognitive impacts. In existing studies, sketch maps are used frequently to measure cognitive maps. However, little work has been done on invariant spatial information in sketch maps, which is the information of spatial configurations representing correctly the …
Development And Evaluation Of A Geographic Information Retrieval System Using Fine Grained Toponyms, Damien Palacio, Curdin Derungs, Ross S. Purves
Development And Evaluation Of A Geographic Information Retrieval System Using Fine Grained Toponyms, Damien Palacio, Curdin Derungs, Ross S. Purves
Journal of Spatial Information Science
Geographic information retrieval (GIR) is concerned with returning information in response to an information need, typically expressed in terms of a thematic and spatial component linked by a spatial relationship. However, evaluation initiatives have often failed to show significant differences between simple text baselines and more complex spatially enabled GIR approaches. We explore the effectiveness of three systems (a text baseline, spatial query expansion, and a full GIR system utilizing both text and spatial indexes) at retrieving documents from a corpus describing mountaineering expeditions, centred around fine grained toponyms. To allow evaluation, we use user generated content (UGC) in the …

Visualizing Patterns In Spatially Ambiguous Point Data, Jonny Huck, Duncan Whyatt, Paul Coulton
Visualizing Patterns In Spatially Ambiguous Point Data, Jonny Huck, Duncan Whyatt, Paul Coulton
Journal of Spatial Information Science
As technologies permitting both the creation and retrieval of data containing spatial information continue to develop, so do the number of visualizations using such data. This spatial information will often comprise a place name that may be "geocoded" into coordinates, and displayed on a map, frequently using a "heatmap-style" visualization to reveal patterns in the data. Across a dataset, however, there is often ambiguity in the geographic scale to which a place-name refers (country, county, town, street etc.), and attempts to simultaneously map data at a multitude of different scales will result in the formation of "false hotspots" within the …
Knowledge Formalization For Vector Data Matching Using Belief Theory, Ana-Maria Olteanu-Raimond, Sebastien Mustière, Anne Ruas
Knowledge Formalization For Vector Data Matching Using Belief Theory, Ana-Maria Olteanu-Raimond, Sebastien Mustière, Anne Ruas
Journal of Spatial Information Science
Nowadays geographic vector data is produced both by public and private institutions using well defined specifications or crowdsourcing via Web 2.0 mapping portals. As a result, multiple representations of the same real world objects exist, without any links between these different representations. This becomes an issue when integration, updates, or multi-level analysis needs to be performed, as well as for data quality assessment. In this paper a multi-criteria data matching approach allowing the automatic definition of links between identical features is proposed. The originality of the approach is that the process is guided by an explicit representation and fusion of …
A Comparative Study Of Linear And Region Based Diagrams, Björn Gottfried
A Comparative Study Of Linear And Region Based Diagrams, Björn Gottfried
Journal of Spatial Information Science
There are two categories of objects spatial information science investigates: actual objects and their spatial properties, such as in geography, and abstract objects which are employed metaphorically, as for visual languages. A prominent example of the latter are diagrams that model knowledge of some domain. Different aspects of diagrams are of interest, including their formal properties or how human users work with them, for example, with diagrams representing sets. The literature about diagrammatic systems for the representation of sets shows a dominance of region-based diagrams like Euler circles and Venn diagrams. The effectiveness of these diagrams, however, is limited because …

From Wanted To Weeds: A Natural History Of Some Of New England’S Introduced Plants, Jessamy R. Luthin
From Wanted To Weeds: A Natural History Of Some Of New England’S Introduced Plants, Jessamy R. Luthin
Maine History
When the Europeans first colonized New England they initiated the process of transforming the landscape into something more familiar. In order to ensure access to food and medicine and recreate the pastoral landscape of the Old World they brought with them a variety of known plant species for cultivation. With time, shifts in medical practice, agriculture, food preservation, and dietary preferences, reliance on these plants declined. As knowledge of these plant species disappeared from popular consciousness, so too did they disappear into the wilds of America, exploiting new found ecological niches, and becoming New England’s naturalized flora. Human labor was …

‘The Farmer’S Family Must Find Compensation In Something Less Tangible, Less Material’: Culture And Agriculture In Maine And New England, 1870-1905”, Cody P. Miller
Maine History
Following the Civil War, American agriculture changed dramatically, and New England was no exception. With new railroad systems, specialized crop markets, and chemical fertilizers, Maine and other New England farmers found themselves as part of an increasingly commercialized agricultural system. Farmers, urban pundits, and agricultural reformers all stressed the need to abandon small, mixed husbandry farming and instead they urged farmers to start treating agriculture like a business. In order to “progress,” one needed to increase acreage and adopt specialized cropping. While many farmers accepted this mantra, others resisted it and argued that there was a moral quality to agriculture …
Old Roots And New Shoots: How Locals And Back-To-The-Landers Remade Maine's Local Food Economy, Eileen Hagerman
Old Roots And New Shoots: How Locals And Back-To-The-Landers Remade Maine's Local Food Economy, Eileen Hagerman
Maine History
Back-to-the-landers who relocated to Maine in large numbers during the 1970s often lacked traditional rural skills and encountered a variety of agricultural challenges related to the state’s harsh climate and poor soils. Many who remained on the land often did so, at least initially, because they received support from elderly neighbors who still practiced low-input, small-scale farming. These neighbors tended to freely share their knowledge and skills and, in return, often benefited from the young newcomers’ assistance with laborious on-farm tasks. The newcomers worked with their local allies to form organizations, share knowledge, and coordinate marketing efforts tailored to meet …
Rosaries, Disease, And Storehouse Keys: Jesuit Conversion Efforts In Seventeenth-Century Acadia, Heather Sanford
Rosaries, Disease, And Storehouse Keys: Jesuit Conversion Efforts In Seventeenth-Century Acadia, Heather Sanford
Maine History
Throughout the seventeenth century, contests over medicinal orthodoxy between American Indians and Jesuit missionaries revealed the limits of compromise and communicated the values that determined the extent of their cooperation. When French Jesuits arrived in Acadia in 1611, they became witnesses to an epidemic that eventually eliminated an overwhelming majority of the Native population. Publicly proclaiming their desire to save souls, the priests converted disease into an evangelical tool. They began to use healing to persuade Wabanakis of the grace, power, and superiority of the Christian god. This article focuses on the convergence of spirituality and healing in Wabanaki and …

The Olive Tree, Volume 23 Issue 1
The Olive Tree
The Olive Tree, published twice each year by Fogler Library at the University of Maine, features articles about library projects, collections, technological innovations, and events. The hallmark of the Fogler Library Friends, an ancient engraving of an olive tree, was adopted from the title page of La Cosmographie Universelle by André Thevet. The two volume encyclopedia, which was published in Paris in 1575, is shelved in the Library's Special Collections Department. One of the longest living trees, the olive tree parallels the development of civilizations.
