  • FOSS4G
  • Location based services LBS
  • Positioning and GNSS
  • GIS development and customization
  • Spatial decision support systems
  • HPC for geospatial computing
  • Web and mobile GIS 

Remote Sensing & Photogrammetry

  • Spaceborne SAR for studying oceans
  • Ocean surface currents estimation
  • Repeat-pass InSAR for landslides and land surface subsidence
  • Hyperspectral and Multispectral remote sensing for studying vegetation
  • Mapping minerals distribution and composition
  • Monitoring vegetation health status 
  • Crop type mapping and phenology cycles
  • Forest above-ground biomas (AGB) estimation using optical and SAR imagery

Faculty Positions Open: GREL is actively on the lookout for qualified PhD faculty in RS & GISc. If you are interested to apply to be part of this vibrant faculty, just contact Dr. Rizwan Bulbul or Dr. Waqas Qazi.


(16-01-17) GREL is launching the 2nd Workshop on Workshop on Data Analysis Techniquesfor Remote Sensing & Geographic Information Science using MATLAB . This course will be led by Dr. Waqas A. Qazi, from 30th Jan. - 3rd Feb., 2017. Detailed course info and registration is available here. Last date for registration: 18th Jan., 2016.


(11-12-16) The ISNET / NARSS Seminar & Hands-on Training Workshop on Earth Remote Sensing with SAR has been successfully held at NARSS (National Authority for Remote Sensing & Space Sciences), Cairo, Egypt, from 27th Nov. - 1st Dec. The hands-on training workshop was conducted by GREL faculty member Dr. Waqas A. Qazi.


(20-10-16) Dr. Waqas A. Qazi delivered a guest talk at Dept. of Meteorology, COMSATS Institute of Information Technology, Islamabad, on "SAR Remote Sensing Applicatons" during their monthly seminar series.


(04-07-16) GREL faculty member Dr. Rizwan Bulbul and MS student Ahsan Abbas recently completed formal scientific and technical review of the book "GeoProcessing with Python." This included testing the code, identifying / removing bugs, and identifying / installing required libraries.


(23-06-16) GREL is launching the 2nd Summer School on Earth Remote Sensing with Synthetic Aperture Radar (SAR). This course will be led by Dr. Waqas A. Qazi, from 1-5th Jan., 2016. Detailed course info and registration is available here. Last date for registration: 20th July, 2016.


(12-05-16) Dr. Majid Nazeer, recent PhD graduate from Department of Land Surveying and Geo-Informatics, at The Hong Kong Polytechnic University, Hong Kong, will be delivering a guest talk on Atmospheric Correction of Remote Sensing Imagery and Coastal Water Quality Applications at GREL Lab, tomorrow, 13th May, from 10:30 AM to 12 PM.


(22-04-16) Forest ground survey was conducted by GREL team from 18-20th April for undergrad Final Year Project. The survey team was led by Dr. Waqas A. Qazi and Mr. Naeem Shahzad, and included 1 MS and 2 BS students. The survey was conducted in Ghora Ghali forest, Murree Forest Division, with the support of Forest Dept., Govt. of the Punjab. Plot survey methodology was used and tree DBH / height were measured. These surveyed plots will be used for regression modeling with remote sensing data for forest AGB estimation.


 (23-12-15) GREL is launching its 1st Workshop on Workshop on Data Analysis Techniquesfor Remote Sensing & Geographic Information Science using MATLAB . This course will be led by Dr. Waqas A. Qazi, from 25-29th Jan., 2016. Detailed course info and registration is available here. Last date for registration: 18th Jan., 2016.


 (27-11-15) ESA has accepted a Cat-1 research proposal by Dr. Waqas A. Qazi to study and analyse landslides and slope stability in KPK post-2005 Kashmir earthquake. ESA has granted a quote of 180 SAR images from Envisat ASAR for the research. As part of this research, repeat-pass InSAR processing will be developed and implemented in-house at GREL.
