Satellite Imagery, GPS Survey Data - Freelance GIS

GIS Analyst / GIS Specialist Role Overview We are seeking a detail-oriented GIS Analyst to support geospatial data management, spatial analysis, mapping, and visualization. The role involves working with GIS platforms, satellite imagery, GPS survey data, and spatial databases to generate accurate geospatial insights and support decision-making. The candidate will develop maps, dashboards, spatial models, and web-based GIS applications using tools such as ArcGIS, QGIS, Google Maps Platform, and spatial data processing libraries. Key Responsibilities1. Geospatial Data Collection & Management Collect, clean, and manage geospatial datasets from GPS surveys, satellite imagery, drone surveys, Google Maps data, field surveys, and spatial databases. Maintain geodatabases, shapefiles, raster datasets, vector layers, and spatial metadata. Perform data validation, coordinate transformation, and projection management. Integrate datasets from OpenStreetMap (OSM), Google Maps, remote sensing platforms, and government GIS portals. 1. Field Survey & Data Acquisition Conduct GIS field surveys using GPS devices, mobile GIS tools, and survey applications. Use Google Maps, Survey123, Collector for ArcGIS, and mobile data collection apps for real-time geospatial data capture. Perform topographic surveys, asset mapping, and ground-truthing for spatial accuracy. Process drone imagery, LiDAR data, and GPS coordinates for spatial mapping. 1. Spatial Analysis & Geospatial Modeling Perform spatial analysis including buffer analysis, overlay analysis, network analysis, proximity analysis, interpolation, hotspot analysis, and terrain modeling. Use ArcGIS Spatial Analyst, QGIS processing tools, and geostatistical methods. Conduct location intelligence analysis, route optimization, and geospatial clustering. Analyze spatial patterns using spatial statistics, density mapping, and predictive modeling. 1. Cartography & Data Visualization Design high-quality maps, thematic maps, dashboards, and geospatial visualizations. Create interactive maps and web GIS applications using ArcGIS Online, Google Maps API, Mapbox, Leaflet, or GeoServer. Prepare spatial reports, dashboards, and visual analytics for stakeholders. 1. GIS Tools, Automation & Integration Work with ArcGIS Pro, ArcMap, QGIS, GDAL/OGR, PostGIS, GeoServer, and ArcGIS Online. Automate workflows using Python (ArcPy, GeoPandas, Shapely), SQL, or scripting tools. Integrate Google Maps API, geocoding services, routing APIs, and location-based services. Process and analyze remote sensing imagery using tools such as Google Earth Engine, ENVI, or SNAP. 1. Project Support & Documentation Collaborate with urban planners, environmental scientists, engineers, and survey teams on geospatial projects. Prepare technical documentation, spatial data reports, and GIS project deliverables. Provide GIS training, troubleshooting, and data support for internal teams. Required Qualifications Bachelor’s degree in GIS, Geography, Geomatics, Geoinformatics, Environmental Science, Urban Planning, or related field. Proficiency in ArcGIS Pro, QGIS, and geospatial data analysis. Strong knowledge of coordinate systems, map projections, spatial data structures, and geospatial databases. Experience in spatial analysis, geospatial visualization, and map production. Strong analytical, documentation, and communication skills.
