Geospatial data availability, interoperability, and integration remain a problem today. Current spatial data infrastructures (SDIs) are of limited use particularly to non-expert user communities. GeoBrain, a NASA funded project, has aimed to address those challenges, facilitate easy use of geospatial data and overcome some limitations of current SDIs through building a data-intensive, Serviceor...

Mobile GIS applications are gaining attention due to a wide range of potential target applications such as ecommerce, tourism, education, agriculture, and field research. This requires easy-to-use geospatial applications operating on mobile devices to enable both visualization and editing of widely-used geospatial data and formats. This paper introduces gvSIGDroid, an open source geospatial mob...

Session Abstract Many scholars, professionals, and students have begun to employ geospatial analysis in their research; however, the teaching of geospatial thinking is still in its formative stages. Archaeologists deal with information that is inherently spatial in nature; thus, archaeology provides an ideal setting to develop spatial thinking. This symposium focuses on geospatially related top...

1. OBJECTIVES The overall objective of this proposal is to model and mine geospatial (GS) patterns in multijurisdiction and multi-temporal (MJMT) datasets to accurately track, monitor, and predict human activities. Several scientific and technical challenges arise when modeling GS patterns in MJMT datasets due to the spatio-temporal nature and heterogeneity of datasets. These represent major ba...

Many techniques have been proposed for visualizing uncertainty in geospatial data. However previous empirical research on the effectiveness of visualizations of geospatial uncertainty has focused on user intuitions rather than objective measures of performance when reasoning under uncertainty (MacEachren, et. al, 2012). In two experiments, we examined the effectiveness of four alternative visua...

With regarding to web GIS, OGC promotes WFS allowing a client to retrieve geospatial data encoded in GML which is a modeling language to encode the semantics, syntax and schema of geospatial information resources. Even though GML provides benefits for geographic description, it is too heavy to be processed by mobile devices. In order to address the issue, this paper evaluates GML service with W...

Few geospatial data representations are more basic than the bounding box; a rectangle surrounding a geographic feature or dataset. Bounding boxes are a key component of geospatial metadata and lie at the heart of many computational geometry algorithms as well as spatial indexing systems. Despite their ubiquity and common use, bounding boxes are more complicated than they first appear. The phras...

Traditional geospatial information platforms are built, managed and maintained by the geoinformation agencies. They integrate various geospatial data (such as DLG, DOM, DEM, gazetteers, and thematic data) to provide data analysis services for supporting government decision making. In the era of big data, it is challenging to address the dataand computingintensive issues by traditional platforms...

In this paper the authors present an approach for the semantic annotation of RESTful services in the geospatial domain. Their approach automates some stages of the annotation process, by using a combination ofresources and services: a cross-domain knowledge base like DBpedia, two domain ontologies like GeoNames and the WGS84 vocabulary, and suggestion and synonym services. The authors' approach...

The role metadata have played in the management of geospatial datasets has been widely documented (Göbel and Lutze, 1998; Kim, 1999; Tsou, 2002; Limbach et al., 2004). Often employed by institutions to organise, maintain and document their geographic resources internally, metadata can also provide a vehicle for exposing marketable data assets externally when contributed to geospatial exchange i...
