Abstract: Image geolocalization, in which, traditionally, an AI model predicts the
precise GPS coordinates of an image is a challenging task with many downstream
applications. However, the user cannot utilize the model to further their
knowledge other than the GPS coordinate; the model lacks an understanding of
the location and the conversational ability to communicate with the user. In
recent days, with tremendous progress of large multimodal models (LMMs)
proprietary and open-source researchers have attempted to geolocalize images
via LMMs. However, the issues remain unaddressed; beyond general tasks, for
more specialized downstream tasks, one of which is geolocalization, LMMs
struggle. In this work, we propose to solve this problem by introducing a
conversational model GAEA that can provide information regarding the location
of an image, as required by a user. No large-scale dataset enabling the
training of such a model exists. Thus we propose a comprehensive dataset GAEA
with 800K images and around 1.6M question answer pairs constructed by
leveraging OpenStreetMap (OSM) attributes and geographical context clues. For
quantitative evaluation, we propose a diverse benchmark comprising 4K
image-text pairs to evaluate conversational capabilities equipped with diverse
question types. We consider 11 state-of-the-art open-source and proprietary
LMMs and demonstrate that GAEA significantly outperforms the best open-source
model, LLaVA-OneVision by 25.69% and the best proprietary model, GPT-4o by
8.28%. Our dataset, model and codes are available
