A spatial assessment of temporal forest cover changes is essential for effective forest conservation and management practices. This study analyzes changes in forest cover and the evolution of forest spatial configuration using Landsat satellite imagery over the past three decades (1990–2020) in Azad Jammu and Kashmir (AJK), Pakistan. To achieve the...
We present TaxaBind, a unified embedding space for characterizing any species of interest. TaxaBind is a multimodal embedding space across six modalities: ground-level images of species, geographic location, satellite image, text, audio, and environmental features, useful for solving ecological problems. To learn this joint embedding space, we leve...
Crop field boundaries are foundational datasets for agricultural monitoring and assessments but are expensive to collect manually. Machine learning (ML) methods for automatically extracting field boundaries from remotely sensed images could help realize the demand for these datasets at a global scale. However, current ML methods for field instance...

The rapid population growth and rising per capita incomes have caused the city to generate massive amounts of municipal waste, indicating a serious environmental threat. Solid waste disposal has become a crucial problem for several municipalities. The selection of suitable waste disposal sites is a crucial problem in the urban areas of developing c...
A soundscape is defined by the acoustic environment a person perceives at a location. In this work, we propose a framework for mapping soundscapes across the Earth. Since soundscapes involve sound distributions that span varying spatial scales, we represent locations with multi-scale satellite imagery and learn a joint representation among this ima...
We propose a weakly supervised approach for creating maps using free-form textual descriptions. We refer to this work of creating textual maps as zero-shot mapping. Prior works have approached mapping tasks by developing models that predict a fixed set of attributes using overhead imagery. However, these models are very restrictive as they can only...
The rapid urbanization observed in various regions worldwide has led to the transformation of agricultural, forest, and green spaces into grey areas. The expansion of these grey areas contributes to heat wave events and an overall increase of average temperatures in specific regions due to their high reflectance properties. This study focuses on an...

Groundwater is a vital natural resource that is essential for the survival of humans and ecosystems alike. However, the depletion of the global water table has become a significant cause for concern. Hence, it is imperative that groundwater monitoring is managed in a systematic and sustainable way to ensure its long-term availability. Geospatial ma...
We propose a novel weakly supervised approach for creating maps using free-form textual descriptions (or captions). We refer to this new line of work of creating textual maps as zero-shot mapping. Prior works have approached mapping tasks by developing models that predict over a fixed set of attributes using overhead imagery. However, these models...

The current study is an attempt to analyze the distribution and trends of various crime types,...
The present study explored the changes in monthly streamflow in the Hindukush–Karakoram–Himalaya (HKH) region within Pakistan using the recently developed trend analysis method known as innovative polygon trend analysis (IPTA). The monthly streamflow data of 34 gauging stations installed in the HKH region was analyzed, and the Pettitt test was appl...
Recently remarkable advancement development of unmannedaerial vehicles (UAVs) has been observed and their applications have beenshown in many fields such as agriculture, industry, and environmentalmanagement. However, in the mining industry, the application of UAVtechnology remains potential. This paper presents a low-cost unmannedaerial vehicle te...
Abrupt changes in climatic conditions, exploitation of natural resources, and land degradation exacerbate soil erosion. This study provides a comprehensive assessment of soil erosion dynamics in Pakistan for 2005 and 2015 at 1 km2 spatial resolution using six influencing factors: rainfall erosivity (R), soil erodibility (K), slope-length (L), slope...
A country’s food needs mainly depend upon its agriculture resources and require reliable information related to crop health, distribution, and acreage estimation to manage and monitor resources to implement a sustainable agricultural system. Different methodologies have been used to collect this information. However, the availability of earth resou...
