GIS Analyst with 11+ years of experience in spatial data management, advanced raster analysis, and professional cartography for reports, research projects, and institutional platforms. I help clients transform spatial data into clear, accurate maps and well-structured GIS datasets. I specialize in organizing and maintaining GIS databases, ensuring data quality, and producing effective cartographic visualizations for analysis and communication. I have extensive experience with ArcGIS Desktop, ArcGIS Pro, ArcGIS Online, and ArcGIS Enterprise, as well as SQL Server, Microsoft Access, and Excel. My work also includes spatial data processing, raster analysis, and creating maps from diverse datasets such as shapefiles, coordinate tables, and survey data. I also use R for data analysis and visualization, and have basic knowledge of Python and Google Earth Engine for geospatial workflows. Previously, I worked at the National Geographic Institute of Argentina as part of the Institutional Geographic Database Administration team. In that role I contributed to municipal Spatial Data Infrastructure projects, managed geospatial metadata, and participated in the national metadata working group of IDERA. I hold a Bachelor's degree in Geography and I am currently pursuing a Master's degree in Integrated Water Resource Management at the University of Costa Rica. Beyond technical GIS work, I am interested in cartography as a communication tool and enjoy exploring the intersection between mapping and visual design. Argentinian currently based in Costa Rica.

What does a remote Sensing specialist do?

A remote sensing specialist processes satellite, aerial, and drone imagery to extract measurable data about the earth’s surface. This role transforms raw sensor inputs into classified maps and spatial datasets that support environmental monitoring, urban planning, and resource management. You interpret spectral signatures to identify land cover types, track changes over time, and validate geographic features with precision.

  • Acquire and preprocess raw imagery from satellites, aircraft, or drones to correct for atmospheric interference, geometric distortions, and sensor noise before analysis begins. This foundational step ensures the spatial data maintains high accuracy and consistency for downstream modeling and interpretation tasks.
  • Perform image classification and thematic mapping by applying supervised or unsupervised algorithms to distinguish between land use categories such as vegetation, water bodies, and built environments. You generate detailed land cover outputs that serve as critical baselines for ecological studies and infrastructure development projects.
  • Conduct temporal change detection to identify and quantify shifts in landscape features across multiple time periods. This work involves comparing historical and current imagery to highlight deforestation, urban expansion, or crop health variations, then exporting these findings as clear visualizations for stakeholder review.
  • Convert processed remote sensing results into GIS-ready formats that integrate seamlessly with existing geographic information systems. You manage geospatial data layers, perform accuracy assessments, and structure attributes so other teams can query, analyze, and visualize the spatial information within their preferred mapping software.

How to hire a remote Sensing specialist on Upwork

Step 1: Post a job

Define your spatial analysis needs clearly to attract qualified candidates. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description in seconds. Describe your project requirements in a few sentences, and Uma creates a tailored post for this role. You can write a new post, update a saved draft, or reuse an existing one.

  • Specify required imagery sources, such as satellite, aerial, or drone data, and list preprocessing steps like atmospheric correction.
  • List specific deliverables, including land cover maps, change detection reports, or GIS-ready vector layers for integration.
  • Mention essential software proficiency, such as ArcGIS Pro image classification workflows or other remote sensing analysis tools.

Step 2: Evaluate candidates

Review portfolios for evidence of accurate spatial data processing and visualization. Look for classified imagery results and thematic maps that demonstrate technical precision. Uma can run instant video interviews and build shortlists with side-by-side comparisons to speed up your review.

  • Check for before-and-after examples of temporal change detection to verify their ability to track environmental shifts over time.
  • Examine sample GIS datasets for topological consistency and attribute accuracy to ensure they meet professional standards.
  • Assess visualizations for clarity and correct symbology, confirming they communicate complex spatial findings effectively to stakeholders.

Step 3: Interview your top choices

Discuss technical approaches to image classification and feature extraction. Ask about their experience with specific sensors and data formats relevant to your project. Schedule and conduct these interviews within Upwork Messages, which generates an immediate transcript and summary after each session.

  • Ask how they handle noise reduction and geometric corrections during the preprocessing phase to maintain data integrity.
  • Request examples of how they validated classification accuracy using ground truth data or independent reference sources.
  • Inquire about their workflow for converting raster outputs into vector formats suitable for downstream GIS applications.

Step 4: Agree on scope and begin work

Set clear milestones for data acquisition, processing, and final map delivery. Use Upwork Messages and the contract workroom to manage communication and share large geospatial files securely. Identity verification, payment protection, hourly tracking, and project funds add security to every engagement.

  • Define exact output formats, such as GeoTIFFs for rasters or Shapefiles for vectors, to ensure compatibility with your systems.
  • Establish accuracy thresholds for classified land use categories to guarantee the analytical results meet your quality standards.
  • Set deadlines for intermediate reviews of preprocessing steps to catch errors before final feature extraction begins.
