The article presents the authors’ experiences in designing a storytelling map guide for the botanical gardens of Palacký University, Czech Republic, from a pedagogical point of view. The authors introduce a three-pillared original concept. The overall educational contribution is a combination of educational, thematic and technological knowledge which supports successful engagement in the storytelling process. In the Storytelling Map Guide for the Botanical Gardens and Greenhouse Collections, the first pillar represents the educational aspect. Botanical knowledge and familiarity with the study area, i.e. the Palacký University Botanical Gardens, represent the thematic pillar. The technological pillar is covered by knowledge of software, cartography and application design skills, including an overview of contemporary storytelling applications. Finally, the educational impact and benefits to students of geoinformatics are discussed.

There have been many changes in the spatial composition and formal delimitation of administrative boundaries of Czech municipalities over the past 30 years. Many municipalities have changed their official status; they separated into ones that were more independent or were merged with existing ones, or formally redrew their boundaries due to advances in mapping technology. Such changes have made it almost impossible to analyze and visualize the temporal development of selected socioeconomic indicators, in order to deliver spatially coherent and time-comparable results. In this data description, we present an evolution of a unique (geo) dataset comprising of the administrative borders of the Czech municipalities. The uniqueness lies in time and topologically justified spatial data resulting in a common division of the administrative units at the LAU2 level, valid from 1995 to 2019. Besides the topologically correct spatial representations of municipalities in Czechia, we also provide correspondence tables for each year in the mentioned period, which allows joining tabular statistics to spatial data. The dataset is available as a base layer for further temporal and spatial analyses and visualization of various socioeconomic statistical data.

The article describes the process of aggregation of media-based data about the coronavirus pandemic in the Olomouc region, the Czech Republic. Originally non-spatially located news from different sources and various platforms (government, social media, news portals) were automatically aggregated into a centralized database. The application “COVID-map” is an interactive web map solution which visualizes records from the database in a spatial way. The COVID-map has been developed within the Ad hoc online hackathon as an academic project at the Department of Geoinformatics, Palacký University Olomouc, Czech Republic. Alongside spatially localized data, the map application collects statistical data from official sources e.g., from the governmental crisis management office. The impact of the application was immediate. Within a few days after the launch, tens of thousands users per day visited the COVID-map. It has been published by regional and national media. The COVID-map solution could be considered as a suitable implementation of the correctly used cartographical method for the example of the coronavirus pandemic.

Only a limited number of studies have examined land price issues based on official land price maps. A very unique timeline of official land price maps (2006–2019) allowed research to be conducted on four Czech cities (Prague, Olomouc, Ostrava, and Zlín). The main aim of the research was to describe the links between land price, land use types, and macroeconomic indicators, and to compare temporal changes of these links in four cities of different size, type, and structure by using spatial data processing and regression analysis. The results showed that the key statistically significant variable in all cities was population size. The effect of this variable was mostly positive, except for Ostrava, as an example of a developing city. The second statistically significant variable affecting land prices in each city was discount rate. The effect of other variables differed according to the city, its characteristics, and stage of economic development. We concluded that the development of land prices over time was slightly different between the studied cities and partially dependent on local spatial factors. Nevertheless, stagnation in 2010–2011, probably as a consequence of the global economic crisis in 2009, was observed in each city. Changes in the monitored cities could be seen from a spatial point of view in similar land price patterns. The ratio of land area with rising prices was very similar in each city (85%–92%). The highest land prices were typically in urban centers, but prices rose only gradually. A much more significant increase in prices occurred in each city in their peripheral residential areas. The results of this study can improve understanding of urban development and the economic and spatial aspects of sustainability in land price changes.

Currently, virtual reality (VR) is a trend both in general and in specific fields such as interactive maps. The article aims to test the possibilities of deployment of low‐cost virtual reality environment for the 3D spatial panoramic application. It discusses and compares modern trends in hardware (panoramic cameras and glasses) and software in the field of virtual reality. Many panoramic map applications (e.g., the well‐known “Google Street View”) allow us to navigate through applications using VR headsets or on an ordinary 2D monitor. The main aim of the article is to design, develop, and deploy VR map application with different levels of user interaction. It presents two pilot studies with different user's interactivity and technical solutions: “simple” 2D‐based map with 360° panoramic photos and “true” 3D application for VR glasses. The article focuses on the possibilities of creating low‐cost map applications. Therefore, the working process “from camera toward to virtual map application” is described as followed‐up case studies.

Recent developments in web map applications have widely affected how background maps are rendered. Raster tiles are currently considered as a regular solution, while the use of vector tiles is becoming more widespread. This article describes an experiment to test both raster and vector tile methods. The concept behind raster tiles is based on pre-generating an original dataset including a customized symbology and style. All tiles are generated according to a standardized scheme. This method has a few disadvantages: if any change in the dataset is required, the entire tile-generating process must be redone. Vector tiles manipulate vector objects. Only vector geometry is stored on the server, while symbology, rendering, and defining zoom levels run on the client-side. This method simplifies changing symbology or topology. Based on eight pilot studies, performance testing on loading time, data size, and the number of requests were performed. The observed results provide a comprehensive comparison according to specific interactions. More data, but only one or two tiles, were downloaded for vector tiles in zoom and move interactions, while 40 tiles were downloaded for raster tiles for the same interactions. Generally, the WebP format downloaded about three times fewer data than Portable Network Graphics (PNG).

The article presents an interdisciplinary link between the geospatial and the cultural sector. This is a unique study of Central Europe in visualizing and interpreting the spatial location of elements in cultural and creative industries. The main purpose was to create suitable visualizations and to process the spatial aspects of cultural and creative industries in a cartographical environment. A team of professionals from several fields (geoinformatics, economics, culture, social sciences, cartography) was assembled to map the creative industries in Olomouc Region, Czech Republic. A total of 1,211 subjects were identified which created the conditions for the employment of more than 5,000 people. Their turnover exceeds EUR 190,000,000 annually. This study was based on an initially examined dataset. Seven spatial analyses were applied. Thirty analogue maps and one interactive map application were created. The point character map was the most used one. The price map, as a background layer, was considered very useful for further map reading. The essential phenomena were topics of population density and transport. Based on the generated map outputs, we found that subjects had a tendency to concentrate in the city center or in areas with higher prices and service levels.

There has been an enormous technological boom that impacted all areas of geoscience in the past few decades. Part of the change was also the process of democratization of cartography as well as geographic information systems (GIS), together with new approaches that have emerged, bringing social dimension into cartography and GIS. These new approaches were variously labelled as critical cartography, collaborative mapping, digital citizenship, Bottom-up GIS and Participatory GIS. The paper describes the role of collaborative mapping and digital participation in the process of community building and community assets mapping. Secondly, we will use the examples of Kenya and Peru to support our findings of community development. Thirdly, we will discuss a possible further development within the use of OpenStreetMap (OSM) for remote communities. The analysis compares approaches and experiences in different countries on different continents.

We are now generating exponentially more data from more sources than a few years ago. Big data, an already familiar term, has been generally defined as a massive volume of structured, semi-structured, and/or unstructured data, which may not be effectively managed and processed using traditional databases and software techniques. It could be problematic to visualize easily and quickly a large amount of data via an Internet platform. From this perspective, the main aim of the paper is to test point data visualization possibilities of selected JavaScript Mapping Libraries to measure their performance and ability to cope with a big amount of data. Nine datasets containing 10,000 to 3,000,000 points were generated from the Nature Conservation Database. Five libraries for marker clustering and two libraries for heatmap visualization were analyzed. Loading time and the ability to visualize large data sets were compared for each dataset and each library. The best-evaluated library was a Mapbox GL JS (Graphics Library JavaScript) with the highest overall performance. Some of the tested libraries were not able to handle the desired amount of data. In general, an amount of less than 100,000 points was indicated as the threshold for implementation without a noticeable slowdown in performance. Their usage can be a limiting factor for point data visualization in such a dynamic environment as we live nowadays.

In this study, the authors created an overview of the usage of heat maps as a GIS visualization method. In the first part of the paper, a significant number of studies was evaluated, and the technique was thoroughly described to set up a base level for further research. At this moment, the most used input data for heat maps are point data. While these data fit the method very well, also studies based on line and polygon data were found. The second part of the paper is devoted to an exploratory study on traffic accident data of the Olomouc city, Czech Republic. Even spatial distribution of the dataset by geographical information system makes it the perfect example of heat map usage. These data were visualized in multiple ways changing color range, kernel size, radius, and transparency. Two groups of users were created in order to evaluate these heat maps. One group was consisting of those educated or working in cartography. The second one was consisting of the general public. Created heat maps were shown to these volunteers and their task was to decide their preferred solution. Most of the users chose bright colors with a negative feeling, such as red, for traffic accident visualization. The best settings for transparency was identified to be around 50%. The final questions were about map readability based on radius. This setting is tied to map scale but follows a common trend throughout the research. The results of this work are a general set of recommendations and specific evaluation of the exploratory study regarding traffic accidents spatial data. The general recommendations include basic principles of the method, implementation by GIS, suitable data and correct usage of heat maps. The evaluation is answering specific questions regarding heat map settings, style and presentation in the specific case.

See-Think-Do is a framework originally used as an approach focused on a service and product marketing on the Internet. Customers can be classified into three groups according to their involvement from potential users to real customers. The article presents an idea of public involvement in community mapping in three levels: “See”—almost any user; “Think”—potential contributors; and “Do”—interested users. The case study implements the See-Think-Do framework as an awareness-based approach used for The Crisis Map of the Czech Republic. It is an Ushahidi-based crowdsourcing platform for sharing spatial and multimedia information during crisis situations, e.g. disaster floods in 2013. While the current crisis projects use public mapping just at the onset of the disaster, according to See-Think-Do any user can be considered as a potential contributor even during the dormant period. The focus is put on the "See" and "Think" groups of contributors, which are currently ignored. The objective of this paper is to summarize approaches (social networks, mass-media, emailing, gamification, …) and tools (GIT/GIS, ICT, multimedia) for increasing the awareness about the project within the resting phase. That recruits a higher number of both active and passive users during the disaster. It allows the training in ICT, cartographical, spatial and GIS skills in a non-stressful way and the targeting on specific operators. Volunteers from the "Think" group may be used for data processing or rectification, GIS professionals from the "Do" group for data verification. The results refer that contributors with already established skills and required literacy (interface, data uploading) provide data faster and more accurate, the usability of the project increases based on users' comments.

Olomouc city, located in the east part of Czech Republic, is historically affected by floods from Morava River. This paper describes designing of web application for crisis management support. Especially it is focused on the support of inhabitants’ evacuation from flooded objects and areas. The application deals with Rich Internet Application concept and Service-oriented architecture. It has been developed by Apache Flex technology. It allows implementation of number modern features and tools into the fully web application. Only web browser is needed for running; no installation process is required. Application itself does not contain any data because of following Service-oriented architecture. All spatial layers are connected as a web mapping services according to their character: Representational State Transfer, Web Map Service or Web Feature Service. This approach ensures that data are updated constantly. The main purpose of the application is visualization of flood areas of Morava River in Olomouc city. It contains two kinds of data. Real data was captured during floods in 1997 and 2006. On the other hand, data of statistical prediction flow for hundred-year (Q100), twenty-year (Q20) and five-year (Q5) flood periods. The flooded buildings and streets are displayed as affected depending on selected layer. Both spatial and tabular tools are enabled for selected features. User can display flooded cadastral area, streets and address points with a number of inhabitants, buildings and many other characteristics useful for evacuation process. This application has been developed in cooperation with the Department of Protection of Olomouc Municipality that provided the data for the application.
