Wireless Sensor Networks (WSNs) have been widely used in agricultural productions. As a critical problems in WSNs, node deployment has a direct impact on the effectiveness of routing and data fusion ...operations as well as on the accuracy of anticipated coverage in several agricultural scenarios, e.g., mono-crop and mixed-crop farmlands. Network simulations are necessary for testing the effectiveness of deployment algorithms, but some of them lack the accuracy of real-world deployments. This is due to the fact that analogue maps in these network simulations do not take into account the nature of the terrain, for example obstacles such as buildings and trees in the line of vision for sensors, uneven surfaces and elevations for hilly terrains, the node locations obtained by the deployment algorithms in these analogue maps cannot be mapped to the actual farmland. In this paper, we present a methodology of constructing analogue map called AnaMap for providing both simulation and visualization of the actual farmland with the characteristic of partition structure and irregular boundary to assist the investigation of node deployment algorithms in agricultural environment. One case study is described to prove the usability of AnaMap.
People discount projected impacts of climate change that they see as spatially or temporally remote. To overcome this, climate change outreach must communicate impacts as local, concrete, immediate, ...and situated in a well-understood frame of reference. Spatial-analog mapping may meet this challenge: by drawing on people's experience of existing climates, this technique matches a locality's projected climates with present-day climates of other localities. However, analog maps' effect on climate impact perceptions has not been compared with the effect on climate impact perceptions elicited by standard climate change mapping techniques. Accordingly, this study considers whether residents of Centre Region, Pennsylvania, who are shown spatial-analog maps for future Centre Region temperatures, perceive impacts as more salient than do residents shown the same temperature-change information directly using color-banded isallotherm maps. It also considers how responses differ when this information is presented using only text, only maps, or both maps and text. An online survey of 3094 members of 11 Centre Region organizations presents the maps and/or text and then assesses respondents' impact perceptions. Based on 444 valid responses, the study finds that respondents, using spatial-analog survey forms, generally expect impacts to be less severe and disruptive than respondents using temperature-change forms. It also finds that respondents using survey forms with maps generally expect impacts to be more severe and disruptive than respondents using text-only forms. Climate change communicators who wish to improve understanding and engagement should therefore strongly consider using maps where possible, but should exercise caution before using spatial-analog approaches.
Conventional paper-based tourist maps are still created and provided by many local tourism organizations, as they have advantages in representing highly detailed and contextual information, although ...the static medium limits the functions of such maps. To benefit these analog maps from location-aware environments, interactivity, and data feedback from mobile devices, a sustainable ecosystem for local tourist maps is proposed. A low-cost solution for developing mobile tourism applications by providing tools to georeference analog maps and integrate multimedia sightseeing information owned by local tourism organizations is implemented. The processes for analog map georeferencing and content integration, as well as the design principles for mobile tourism applications, are introduced and discussed in detail. In cooperation with college students, university campuses, and local tourism organizations, experimental applications were implemented to evaluate the functionality and usability of the proposed mobile mapping application and the feasibility of the proposed solution. Two published applications are introduced briefly, with preliminary analyses using data donated by application users, which have shown positive contributions to understanding users' behavior and requirements.

Maps are important vehicles for storytelling. Although the ubiquity of current web mapping services has brought great conveniences to creating map-based content, they also bring restrictions in map ...representation. Conventional analog maps are still being created and widely used. Some of the well-designed ones are highly contextual, and are more suitable for storytelling with related backgrounds. To utilize analog maps in location-aware mobile environments for storytelling, local and dynamic georeferencing is introduced to attach geospatial information to the analog map images without stretching them and destroying the artistic designs. A data format extended from a popular GIS data standard is designed, for creating and sharing storytelling content easily by attach multimedia resources to georeferenced map images. In cooperation with local communities, prototype developments realized tools for map-based storytelling content creation and smartphone applications for browsing the content in walking tours.
