Focused geospatial services for researchers, academic institutions, and organizations — grounded in academic rigour and real-world practice.
I offer a focused range of geospatial services designed for researchers, academic institutions, and organizations that need reliable, expert-level GIS and remote sensing support. Every service I provide is grounded in academic rigour, practical experience, and a commitment to delivering outcomes that genuinely advance your research or organizational goals. If your specific need is not listed, please contact me — my work regularly extends into new disciplines and applications.
Structured, hands-on training in GIS and remote sensing for students, scholars, faculty, and professionals.
A comprehensive 3-month programme covering GIS fundamentals through advanced deep learning integration for geospatial analysis. Delivered by Dr. Aran Castro A J, GIS Manager. Available online and on-demand.
End-to-end workflow: satellite download, classification, accuracy assessment, change matrix, and publication-ready maps. Duration: 2–3 days.
Shoreline extraction, DSAS setup, transect generation, EPR, LRR, and NSM calculation — based directly on my doctoral research. Duration: 1–2 days.
Complete CVI methodology using Gornitz's approach. Parameter selection, ranking, weighting, GIS integration, and vulnerability mapping. Duration: 1–2 days.
Tailored programmes for specific departmental or institutional needs. Previous programmes at University of Madras, SRM University, TRP Engineering College, and IIRS.

End-to-end geospatial research support for PhD scholars and professors across any discipline.
Thousands of PhD scholars in India reach a stage where they need GIS or remote sensing analysis but lack the skills, software access, or methodological guidance to execute it properly. They spend months struggling with unfamiliar software, produce substandard maps, or abandon geospatial components entirely. I exist to solve this exact problem — completely and efficiently.
Identifying appropriate data sources, selecting analytical methods, defining the GIS workflow, and ensuring the methodology is rigorous enough for Scopus and SCI journal publication.
Acquisition of Landsat, Sentinel, ALOS, Cartosat, or other sources; radiometric, geometric, and atmospheric correction; analysis-ready data preparation.
Complete workflow: spectral signature selection, supervised or unsupervised classification, accuracy assessment with error matrix and kappa coefficient, multi-temporal change detection.
Full DSAS-based analysis: shoreline extraction from multi-temporal satellite imagery, transect generation, EPR, LRR, NSM, and statistical reporting.
Complete CVI construction using Gornitz's approach or modified frameworks. Parameter extraction, ranking, weighting, and vulnerability mapping.
Buffer, overlay, proximity, interpolation (IDW, Kriging), watershed delineation, DEM analysis, viewshed, network analysis, and more.
Maps meeting Scopus/SCI journal formatting standards. Delivered as high-resolution PNG/TIFF, PDF, and editable project files.
Assistance with structuring methodology, results, and discussion sections. Figure preparation and ensuring geospatial components meet reviewer expectations.
Contact me with your research topic and current stage. Free 15-minute consultation to understand your needs.
Clear scope, timeline, and fee quote. No hidden costs. No vague promises.
We work together — I process and analyse, you learn and understand. I ensure you can defend every output in your viva.
You receive all outputs: processed data, analysis results, publication-quality maps, and full methodology documentation.
Custom geospatial solutions for institutions, government bodies, NGOs, and private organizations.
Geospatial assessment using CVI methodologies, shoreline change analysis, bathymetric analysis, geomorphological mapping, and land use impact evaluation. Deliverables include vulnerability maps and actionable recommendations.
GIS-based spatial analysis for EIAs and environmental monitoring: land use change quantification, vegetation index analysis, water body monitoring, and spatial impact zone delineation.
Multi-temporal satellite-based analysis of land use changes for districts, municipalities, or regions. Urban sprawl, agricultural land loss, forest cover change, waterbody change quantification.
Spatial analysis of temperature trends, rainfall distribution, drought indices, flood risk zones, and sea-level rise impact modelling.
Georeferencing historical maps, spatial analysis of historical settlement patterns, temporal change analysis of cultural landscapes, and interactive historical mapping.
Watershed delineation, drainage network extraction, flood plain mapping, groundwater potential zone identification, and rainfall-runoff modelling.
Professional map production for reports, publications, presentations, and proposals — from simple location maps to complex thematic atlases.
Advisory for organizations implementing GIS infrastructure: software selection, data architecture, workflow design, staff training needs assessment, and GIS strategy development.
For Heads of Departments, Deans, and IQAC Coordinators seeking a quality resource person in GIS and geospatial research methodology.
I have delivered FDPs at nationally recognized institutions including the University of Madras (Department of Applied Geology), the Indian Institute of Remote Sensing (IIRS), SRM University, and TRP Engineering College. My programmes are intensive, hands-on skill-building experiences that leave faculty with tangible capabilities they can apply immediately.
Foundational FDP for faculty across science, engineering, and social science. Core GIS concepts, satellite data access, basic spatial analysis, and integration into existing research.
Intermediate-to-advanced: LULC change detection, shoreline analysis, DEM terrain modelling, and spatial statistical methods for faculty with basic GIS familiarity.
Specialised FDP introducing Python for GIS automation. Automate repetitive tasks, process large datasets efficiently, and build reproducible workflows.
GIS and remote sensing for flood mapping, coastal hazard assessment, earthquake risk zonation, and landslide susceptibility analysis.
A unique methodology-focused FDP drawn from my book Systems Over Software. Challenges faculty to move beyond software operation and develop robust research thinking, problem formulation, and analytical reasoning.
Format Options: One-day awareness programme · Three-day intensive workshop · Five-day comprehensive training with hands-on lab sessions. Available in-person at your institution or online. All programmes include training materials, datasets, and certificates.
