:sparkles: Overview

EarthGPT is a universal multi-modal large language model (MLLM) tailored for the remote sensing (RS) domain. Notably, EarthGPT establishes an effective visual-language cross-modal mutual learning framework, and seamlessly unifies a wide range of RS visual tasks and multi-sensor imagery interpretation in multi-turn dialogues. Specifically, EarthGPT is capable of various visual reasoning tasks, including scene classification, image captioning, region captioning, VQA, visual grounding, object detection, etc. Most importantly, EarthGPT is versatile in understanding multi-sensor imagery across optical, synthetic aperture radar (SAR), and infrared images.

:sparkles: MMRS-1M: Multi-modal Multi-sensor Remote Sensing Instruction Dataset

MMRS-1M is the largest multi-modal multi-sensor RS instruction-following dataset, consisting of over 1M image-text pairs that include optical, SAR, and infrared RS images.

<u>The entire data of MMRS-1M is released! 🚀</u>

Datasets Usage guidelines

1. Each task provides an image file and a corresponding JSON file.

2. The detection and visual grounding data involve coordinate transformation. Taking the horizontal bounding box as an example, assume the horizontal bounding box for the original detection data is [x0, y0, w, h], and the dimensions of the image are width and height. The coordinate transformation is performed as follows:

   First, performing padding：

     if height > width:
        pad_x0 = int((height - width) / 2)
        pad_y0 = 0
        width = height
    else:
        pad_x0 = 0
        pad_y0 = int((width - height) / 2)
        height = width

Then, performing normalization：

        x0 = x0 + pad_x0
        y0 = y0 + pad_y0
        sx0 = x0 / width
        sy0 = y0 / height
        sx1 = (x0 + w) / width
        sy1 = (y0 + h) / height

Finally, [sx0, sy0, sx1, sy1] is the format of the detection boxes used for the detected part of the data in MMRS-1M.
