【摘要】：隨著計算機和網(wǎng)絡科技的迅速發(fā)展,網(wǎng)絡電子地圖成為大眾使用最多的地理位置搜索工具,但相關的理論和技術研究卻多以紙質地圖為研究材料和背景,很難適用于電子屏幕。目前對于網(wǎng)絡地圖標識的研發(fā)更多考慮呈現(xiàn)技術層面,如地圖學與計算機科學對地圖數(shù)據(jù)呈現(xiàn)的技術研究。但是,正如著名地圖學家尹霍夫所言,地圖學應該是藝術傾向的技術科學。同時,地圖標識作為地圖的語言,但與其形狀相關的主、客觀研究偏少。本文以電子地圖標識為研究對象,從主觀藝術層面和客觀搜索效率層面研究。標識藝術性可以依靠主觀評價測量,技術性則可依客觀搜索效率為準。于是,本研究從標識的形狀變量入手,從主觀和客觀兩個方面,成圖前和成圖后兩個階段,對網(wǎng)絡電子地圖的點狀標識符號進行探索研究,以期發(fā)現(xiàn)電子地圖點狀標識的構圖規(guī)律,使電子地圖標識的設計更加符合人們的主觀、客觀需要。在成圖前階段,從主觀角度出發(fā),為探究用戶的主觀偏好,實驗一對網(wǎng)絡地圖符號進行主觀問卷調查。通過比較代表同一地點的不同標識,得到十一個地點的各自最優(yōu)標識(評分總均分最高或較高),且不同類比標識間主觀評價差異顯著。從客觀標準而言,雖然依照形狀對點狀標識進行分類,但分類后標識搜索效率研究較少,多是依主觀經(jīng)驗進行評價。實驗二通過視覺搜索實驗,以用戶反應時和準確率為客觀標準,比較點狀標識不同類別(幾何形態(tài),象形形態(tài),文字形態(tài))的搜索效率。結果發(fā)現(xiàn)三類標識間搜索時間差異顯著,其中幾何形態(tài)標識搜索時間最短�？紤]到標識成圖前后呈現(xiàn)的差異,在成圖后階段,應從搜索背景目標和搜索背景的角度分析標識和地圖雜亂度對搜索效率的影響。實驗三研究標識類型(幾何形態(tài),象形形態(tài),文字形態(tài))與地圖雜亂度(高,中,低)對搜索效率的影響。結果發(fā)現(xiàn)兩者對搜索效率都有影響,且存在交互作用。通過研究,發(fā)現(xiàn)標識類別間在主觀滿意度和客觀搜索效率的上顯著差異,標識影響了電子地圖中目標位置搜索績效的搜索,此研究對網(wǎng)絡地圖標識的研發(fā)具有意義。
[Abstract]:With the rapid development of computer and network technology, network electronic map has become the most popular geographical location search tool, but the related theoretical and technical research is based on the paper map as the research material and background, it is difficult to apply to the electronic screen. At present, more consideration has been given to the presentation of map data in the research and development of network map marking, such as the study of cartography and computer science on the presentation of map data. But, as the famous cartographer Yin Hofu said, cartography should be the technical science of artistic tendency. At the same time, map marking as a map language, but its shape related to the subjective, objective research is less. This article takes the electronic map marking as the research object, studies from the subjective art level and the objective search efficiency level. Marking artistry can be measured by subjective evaluation and technical by objective search efficiency. Therefore, this study starts with the shape variables of the marking, from the subjective and objective aspects, before and after the mapping two stages, to explore the dot marking symbols of the network electronic map. In order to find out the composition rule of electronic map dot marking, the design of electronic map marking is more in line with people's subjective and objective needs. In the pre-mapping stage, from the subjective point of view, in order to explore the subjective preferences of users, a subjective questionnaire survey was conducted on a pair of network map symbols. By comparing the different marks representing the same location, we get the optimal mark (the total average score is the highest or higher) of 11 locations, and the subjective evaluation difference among different analogical marks is significant. According to the objective criterion, although the point-like mark is classified according to the shape, the research on the search efficiency of the mark after classification is less, and most of them are evaluated according to the subjective experience. In the second experiment, the searching efficiency of different types of dot marking (geometric, pictographic and literal forms) was compared according to the objective criteria of user response time and accuracy by visual search experiment. The results showed that there was a significant difference in search time among the three types of identifiers, and the search time of geometric identification was the shortest. In the post-mapping stage, considering the difference before and after the mapping, we should analyze the influence of the identity and the clutter of the map on the search efficiency from the point of view of searching background target and searching background. In experiment 3, the effects of label type (geometric form, hieroglyph form, text form) and map clutter (high, middle and low) on search efficiency were studied. The results show that both of them have an effect on the search efficiency, and there is interaction between them. Through the research, it is found that there are significant differences in subjective satisfaction and objective search efficiency between the identification categories, which affects the search performance of target location search in electronic maps. This research is of great significance to the research and development of network map identification.
