Outline

This paper presents a new benchmark dataset, MapIQ, to expand the research on visual data understanding of multimodal large-scale language models (MLLMs), particularly in Map-VQA (Map-VQA). This dataset encompasses three map types (Choropleth, Cartogram, and Proportional Symbol Maps) and six topics, and evaluates the performance of several MLLMs on six visual analysis tasks. Furthermore, we analyze the impact of map design changes on MLLM performance to explore ways to improve model robustness, geographic knowledge reliance, and Map-VQA performance.

Takeaways, Limitations

Extension of Map-VQA research: Moving beyond existing research limited to choropleth maps, we expand the scope of our research by presenting a new benchmark dataset that includes various map types and topics.
MLLM Performance Evaluation: Evaluate the Map-VQA capabilities of several MLLMs and identify the strengths and weaknesses of the models through performance comparison.
Analysis of the Impact of Map Design: By analyzing the impact of map design changes on MLLM performance, we identify the model's visual comprehension ability and reliance on geographical knowledge, and suggest ways to improve performance.
Limitations:
Regarding the composition of the MapIQ dataset, further discussion may be needed as to whether the six topics and three map types cover all possible visual analysis tasks or are biased towards specific areas.
Further validation is needed to determine whether the results of the map design change experiment can be generalized to all MLLMs.
Further discussion is needed regarding the objectivity and validity of the methodology used to assess the model's dependence on geographical knowledge.
