Table 2: Mapping between tasks and candidate gestures. The table has two columns labeled 'Function' and 'Gesture 1'. Five rows show: 1) Pan - Open hand swipe gesture with illustration of flat hand moving horizontally; 2) Zoom In - Index finger and thumb moving from pinch to open position with spreading motion; 3) Zoom Out - Index finger and thumb moving from open to pinch position with closing motion; 4) Point Placement - Pinch fingers then open gesture, shown with two hand positions; 5) Switch Mode - Sweep open palm left and right, illustrated with palm moving in both directions. Each gesture is accompanied by simple black line drawings demonstrating the hand movements.

Figure 12 showing visualization of contour matching results for experimental area 1 across three panels labeled b, c, and d. Each panel displays overlapping contour lines from Dataset1 (blue) and Dataset2 (orange), with cyan arrows indicating matching results identified by the proposed method. Panel b shows several circular enclosed contour features in the upper left. Panel c displays relatively parallel, wavy horizontal contours with some vertical variation. Panel d shows more complex contour patterns with enclosed shapes in the lower left and converging lines in the upper right. Each panel includes a north arrow and scale bar showing 0, 50, and 100 meters.

Figure 4b) showing Example 2 of headline-with-map versus headline-with-photo posts. Both posts have the headline 'Swiss glaciers lose 10% of volume in worst two years on record' with a user profile icon and reliability rating scale from 1 (Unreliable) to 4 (Fully Reliable). The left post displays a topographic map of Switzerland with colored circles indicating glacier volume changes, with a legend showing changes from 0.00 to -0.75 meters water equivalent and circle sizes representing glacier areas of 10, 50, and 200 square kilometers. The right post shows a photograph of a striped measurement pole on a snowy glacier with mountains in the background under a blue sky.

Flowchart diagram titled 'Thick mapping workflow: from collaborative site assessment to immersive installation.' The workflow progresses through four numbered stages shown in circular vignettes: (1) Introductory training and orientation phase showing people using collaborative data collection platforms like Field Maps, Ushahidi, or Emapic for faster insights; (2) Collaborative on-site assessment through geospatial data collection, depicting groups gathering information in outdoor and indoor settings; (3) Information processing through co-production by micro-groups, showing varied site observations being transformed into qualitative and quantitative metrics through asynchronous teamwork; (4) Co-creation of thick maps and installation for visual representation, illustrating how thread colors represent distinct categories (spatial, natural, or historical layers) in both a vertical hanging installation and a horizontal table-based display with suspended elements.

A comparison grid showing eight different map visualizations of the same geographic area featuring Silver Creek running diagonally from northwest to southeast and Interstate 65 highway running vertically to the east of the creek. The visualizations include: Label (simple map with creek and highway marked), Playground v2.5 (aerial photograph of a winding creek through green landscape), Stable diffusion 3.5 (map showing labeled creek and highway), Janus-Pro 7B (detailed street map with creek system), Map Diffusion (topographic-style map with terrain features), Flux.1-dev (minimalist map with I-65 label), GPT-4o (stylized map with creek and urban features), and MapGenerator (simplified map with creek and highway). The prompt at top describes the geographic layout with key spatial relationships highlighted in red and blue text." The google map shows a section of a geographic area with **a creek** labeled **"Silver Creek"** running **diagonally** from the **northwest to the southeast**. To the **east** of the creek, there is a **major highway** labeled **"I-65"** running **vertically**. The background is a **light green color**, indicating land or a general area.

A horizontal stacked bar chart showing the existence percentage of different harm types in GeoAI ethics cases. Five categories are displayed with icons on the left: eco (economy), phy (physical harm), pri (violation of privacy), psy (psychological harm), and equ (violation of equal rights). Each bar is divided into two segments: magenta representing 'Existence' and tan representing 'Non-existence'. The percentages are: eco shows 41.82% existence and 58.18% non-existence; phy shows 33.22% existence and 66.78% non-existence; pri shows 30.52% existence and 69.48% non-existence; psy shows 18.90% existence and 81.10% non-existence; and equ shows the lowest at 3.60% existence and 96.40% non-existence. A legend in the upper right indicates the color coding for existence (magenta) and non-existence (tan).

Three maps labeled a, b, and c showing different visualizations of the same geographic region. Map a) georeferenced map symbols, which are aggregated into proportional rectangular map symbols, with frequencies indicated inside these shapes. Map b) displays the same region as a dot density map with hundreds of colored dots (appearing in shades of red, orange, yellow, and other colors) distributed across the area, with the highest concentration in the center. Map c) presents a heat map or kernel density visualization with colors ranging from blue (low density) through green and yellow to red (high density), showing smooth gradients of concentration with the most intense areas appearing as red hotspots in the center and upper portions of the map. All three maps include a legend, scale bar, and attribution to OpenStreetMap contributors.

A network graph showing the evolution of seven related studies from 2020 to 2024. The timeline runs horizontally along the x-axis, with seven study names listed vertically on the left: Kang et al., CT Replication, Illinois Reproduction, Chicago Reproduction, Class Projects, VT Pharmacy Extension, and Esri Extension. Each study has a small grid showing reproducibility criteria (indicated by black and white boxes). Circles connected by lines represent different versions of each study, with solid lines indicating direct forks or pulls and dashed lines showing references. Colored symbols within or near circles indicate the type of work: green squares for reproduction, blue circles for reanalysis, red triangles for replication, and purple inverted triangles for extension. The graph shows how these studies branched, referenced, and built upon each other over time, with a note indicating that the HEGSRR template was adopted in 2022. Updates in response to reproduction efforts are noted at the top. The network demonstrates how each study reproduced, reanalyzed, replicated, or extended the original Kang et al. (2020) study (indicated by colored polygons) in sequence, improving upon different aspects of the original work (shown by black boxes in the grids).

A flowchart diagram showing a two-step 'template-render' framework for map symbol generation. The process begins with a user input icon on the left. Step 1 (Template Generation) is shown in a light green box: user input and a knowledge-guided prompt flow into an LLM (represented by a robot icon), which produces a symbol description or 'template' (shown as a document icon). Step 2 (Visual Rendering) is shown in a light blue box: the symbol description flows into a T2I model (represented by a 3D cube icon), which synthesizes a visual symbol from the description and outputs a point symbol or 'render' (shown as a red map pin icon on a folded map). Arrows connect each component from left to right, illustrating the sequential workflow from user input to final rendered map symbol

A diagram illustrating point symbol concept generation using 'Zoo' as an example. On the left, a pink box shows user input: 'Zoo' or 'Design a map symbol for Zoo'. An arrow labeled 'LLM' points to a green box containing the symbol description: 'Symbol of the Zoo, abstract 2D style, white background, stylized image with animal silhouettes and tree elements, rounded rectangle shape with curved top, simple lines for texture.' An arrow labeled 'T2I model' points to the final point symbol on the right: a rounded square icon with dark green background showing silhouettes of two animals (appearing to be a lion and elephant) facing each other under a tree canopy, with a white border and rounded corners.
