From Raw Satellite Data to Research-Grade Maps

Every analysis begins with the right data and the right method. My work spans 72 km of coastline studied, dozens of satellite datasets processed, and publication-quality maps produced for indexed journals — all from Nagercoil, Kanyakumari District.

How I Can Help

How I Can Help You

Three core service areas — all grounded in academic rigour, practical experience, and a commitment to your research outcomes.

GIS Training & Internships

Structured training programmes in GIS, remote sensing, and spatial analysis for students, research scholars, and working professionals. From beginner-level GIS fundamentals to advanced ArcGIS Pro workflows, satellite image processing, and Python for geospatial automation. Available as short-term workshops, semester-long courses, and institutional internship programmes at my Nagercoil centre.

PhD Research & Publication Support

End-to-end geospatial research support for PhD scholars and professors. I assist with research methodology design, satellite data acquisition and processing, LULC classification, shoreline change analysis, coastal vulnerability indexing, spatial statistical analysis, publication-quality map preparation, and manuscript development for Scopus and SCI journals.

Geospatial Consulting

Custom geospatial solutions for institutions, government bodies, NGOs, and private organizations. Services include coastal vulnerability assessment, environmental impact spatial analysis, urban and regional planning GIS, climate data analytics, historical GIS, land use change modelling, and enterprise-level geospatial reporting.

Who I Help

Does This Sound Like You?

Most of my clients come to me with one of these three problems. If any of these resonate, we should talk.

PhD Scholars & Research Students

"My data is ready but I have no idea how to turn it into GIS maps for my thesis."

You have field data, survey results, or satellite imagery — but converting that into publication-ready LULC maps, shoreline change analyses, or vulnerability indices feels overwhelming. I handle the entire geospatial workflow so you can focus on writing.

Professors & Faculty Members

"I want to publish in a Scopus journal but I need a strong geospatial analysis component."

Many high-impact papers in geology, geography, environmental science, and urban planning now require GIS and remote sensing analysis. I collaborate with faculty to design the methodology, run the analysis, and prepare publication-quality figures and maps.

Institutions & Organisations

"We need a coastal/urban/environmental GIS study but don't have in-house geospatial expertise."

Whether it is a coastal vulnerability assessment, an urban heat island study, a hazard risk zonation, or a land use change report — I deliver end-to-end geospatial consulting with clear maps, data, and a written report your organisation can use and publish.

Systems Over Software: How Great GIS Researchers Think

By Dr. Aran Castro A J

Kindle: B0GPJTVSR4 · Paperback: B0GPQ41MKX

This book challenges GIS professionals and researchers to move beyond software button-clicking and develop the systems thinking, research design clarity, and analytical frameworks that separate great geospatial researchers from mere software operators.
