Online Survey of Heterogeneous Users and Their Usage of the Interactive Mapping Platform WorldMap

This article reports on the results of an online survey with 290 heterogeneous users of the interactive mapping platform WorldMap and provides insights into problems faced by such users. Heterogeneous users are users with a variety of GIS skills, educational background, gender, and age categories. We investigate how they interact with online maps and analyse their experience. WorldMap represents as a case study of an online mapping platform which aims to serve researchers and users across disciplines in viewing and creating online interactive maps. We concentrate on operations that are perceived as difficult and very difficult by the majority of users as well as operations that are rarely used. Our aim is to contribute to the discussions on how to improve the design of online GIS-based mapping platforms. We conclude the paper with reflections on the results of our study and ideas for further research.     

Understanding User Interaction Patterns within Online Systems for Public‐Participation Transportation Planning

Many research projects in public‐participation geographic information systems focused on the development of software prototypes that were conceptualized to complement traditional forms of public participation. Given the challenges introduced by the heterogeneity of their user base, system design, and decision making process, empirical evaluations of such systems based on actual use have been scarce. This article reports on a rigorous empirical assessment of human‐computer interaction of users of a web‐based system for participatory transportation planning. We devised three groups of participants with below‐average, average, and above‐average interaction duration through hierarchical cluster analysis. Subsequently, the characteristics of the clusters were subjected to logistic regression analysis to determine the significance and strength of statistical associations between duration of interaction and a host of individual‐level variables. Our results indicate a statistically significant reduction of the odds‐ratio for participants with above‐average duration of interaction in the case of no prior experience with online transportation discussions. No significant associations were found between overall duration of interaction and sociodemographic background, cognitive decision‐making style, and travel behavior. We advocate for the development of adaptable participatory systems which accommodate flexibility in terms of both the user interface and pathways of the decision making process.

Comparing Student Performance in Online and Blended Sections of a GIS Programming Class

Educators and non‐educators alike commonly assume that online courses cannot match the effectiveness of their traditional, face‐to‐face counterparts. This article describes a comparative study of the performance and study habits of two groups of students in a course in Geographic Information Systems (GIS) software programming and customization: one delivered online to adult professionals working asynchronously; the other delivered in a blended, online/face‐to‐face environment to upper‐level undergraduates in residence. Course grades show that the undergraduate cohort underperformed in comparison to the online cohort, in spite of the fact that their version of the course included face‐to‐face lecture and lab time in addition to the online course materials. To explore differences in the study habits of the two groups, all students were asked to keep a diary of the time they devoted to coursework. Information from these diaries suggest that a student's ability to meet learning objectives is less dependent on the course content delivery mechanism than it is on the student's motivation, maturity and time management skills.

Towards a Deeper Understanding of Cartographic Text Visualisation: Assessment of User Preferences and Colour Influence

The main goal of this research is to investigate the influence of a map’s background colour on user preferences regarding labels’ typography, including their size, shape, orientation and texture. Four sets of backgrounds were tested: blank maps, grey scale, hot colours and cold colours. The foreground of these maps is populated with name labels, which are associated with point objects or areal objects. Bertin’s visual variables were applied to this set of name labels, both separately and in combination. User preferences of different typographic variations were registered and compared on the basis of different background colours using a one-way ANOVA. The results indicated that the typographic design of the map labels should not be adapted according to the map’s background colour.

大型贯通测量中加测陀螺定向边的位置选取分析

大型贯通测量中常常使用加测陀螺边来提高贯通测量精度,但目前对于陀螺定向边的位置选取并无明确规范和要求。本文主要探讨了不同位置的陀螺定向边选取对贯通测量精度的影响。实验结果表明,井下选取的陀螺定向边与测定仪器常数的地面已知边之间距离过大对于贯通测量精度影响较大,在井下选取陀螺定向边位置时,应与测定仪器常数的地面已知边距离保持在3 000 m以内为优。

贯通测量误差预计参数的分析与确定

贯通测量误差预计多采用规程规定的测量参数,而规程参数多假设在比较理想的环境下,是经过相应理论推导的结果。但是由于各矿井的具体条件不同,在巷道贯通后分析巷道贯通误差,以现用规程规定的误差参数预计的误差与实际差别较大。因此,各矿要根据自己实际情况的不同,进行误差预计参数的确定。本文首先对贯通测量误差参数的类型和重要性进行了综合评述,并对其中地面控制网误差参数和井下控制网误差参数的理论确定方法进行了介绍,用实测资料进行确定。
