GIS FAQ
What tech leaders ask about GIS before pulling us in:
While the Google Maps API is excellent for basic consumer routing and placing simple markers, a custom GIS application is built for deep analytical power. GIS allows you to perform complex spatial queries (e.g., finding intersections between massive polygons), manage custom raster/vector data layers, analyze terrain, and visualize large enterprise datasets securely.
We are highly proficient in both ecosystems. For clients looking to minimize licensing costs, we architect robust open-source stacks utilizing PostGIS, GeoServer, and Mapbox. For enterprise clients heavily invested in ESRI, our developers build custom web apps, geoprocessing tools, and extensions utilizing ArcGIS Enterprise and the ArcGIS API for JavaScript.
Visualizing millions of points or complex polygons directly will freeze a browser. Our developers optimize this by generating Vector Tiles on the server (using tools like Tippecanoe or pg_tileserv). Vector tiles break massive spatial datasets into small, pre-computed chunks, allowing clients like Mapbox GL JS to render data smoothly at 60 FPS using the GPU.
Standard SQL databases only store numbers and text. PostGIS is an extension for PostgreSQL that adds true spatial data types (Geometries/Geographies) and spatial indexes (GiST). This allows the database to instantly answer complex mathematical questions like 'Which of our delivery trucks are currently inside this custom drawn polygon?' with immense speed.
Yes, this is a very common requirement. Shapefiles are a legacy format that is difficult to query and manage in a multi-user web environment. We use ETL tools like GDAL/OGR and Python to securely migrate your Shapefiles, GeoJSONs, or KMLs into a centralized spatial database like PostGIS, ensuring data integrity and enabling high-performance queries.
Absolutely. Instead of paying high per-transaction fees to commercial routing APIs, we build proprietary routing engines using tools like pgRouting and OSRM (Open Source Routing Machine) paired with OpenStreetMap data. This allows us to calculate optimal routes based on your company's custom restrictions (e.g., heavy truck weight limits on specific roads).
We utilize advanced raster processing libraries like GDAL and cloud-native architectures like Cloud Optimized GeoTIFFs (COG). For complex environmental analysis over time, we integrate with platforms like Google Earth Engine to process massive multispectral satellite datasets without needing to download terabytes of imagery locally.
For highly customized, vector-based, and 3D map rendering, we highly recommend Mapbox GL JS (or open-source alternatives like MapLibre). For simpler 2D mapping needs that require immense flexibility, Leaflet is an excellent, lightweight open-source choice. For heavy 3D data visualizations, we utilize Deck.gl.
