// The buying trigger

You probably need this when…

01

Standard web maps freeze or crash browsers when rendering large spatial datasets (>100k points/polygons).

02

Off-the-shelf dashboard widgets lack complex spatial filtering, polygon drawing, and spatial buffering.

03

High third-party map tile licensing fees make scaling web applications cost-prohibitive.

// Concrete scope

What the engagement delivers

Every item is tied to an acceptance owner and evidence. Final scope is confirmed after data, security, and integration review.

DELIVERABLE 01

Custom Web GIS web application with responsive UI for desktop, tablet, and mobile

DELIVERABLE 02

Vector tile infrastructure (PMTiles, Martin, or Tegola) with global edge caching

DELIVERABLE 03

WebGL-accelerated spatial visualization (Deck.gl, MapLibre GL JS, Leaflet)

DELIVERABLE 04

Spatial query tools: polygon buffering, radius search, routing, and attribute filtering

DELIVERABLE 05

Self-hosted base map layers with zero per-request commercial tile fees

// Delivery process

From evidence to operational handover

  1. 01

    Cartography & UX Design

    Design clean, high-contrast map themes, layer hierarchies, and intuitive spatial interaction patterns.

  2. 02

    Tiling & Data Pipeline

    Optimize vector and raster datasets into Cloud-Optimized GeoTIFFs (COG) and PMTiles for serverless streaming.

  3. 03

    Frontend Engineering

    Implement WebGL shaders, client-side clustering, layer switching, and cross-filter data querying.

  4. 04

    Performance Optimization

    Audit rendering frames, network payloads, and memory management for silky-smooth 60 FPS interaction.

// Proof before promises

How value is verified

No vanity accuracy number. Evidence is chosen around the operational decision and agreed before delivery starts.

  • ✓Proven experience building GeoEditor (browser-based 3D GIS without upload) and BurnScar live map
  • ✓Smooth rendering of 1,000,000+ vector features in browser via WebGL and Deck.gl
  • ✓100% client-controlled map tile hosting reducing map operating costs by over 90%
// Buyer questions

Frequently asked questions

What is the best Web GIS stack for heavy spatial data?+

For performance and scalability, we leverage MapLibre GL JS or Deck.gl on the frontend, PMTiles or Martin vector tile servers, PostGIS on the backend, and FastAPI for spatial endpoints.

Can Web GIS applications run offline or in secure air-gapped networks?+

Yes. Our Web GIS architectures can be packaged with localized tile caches and offline spatial engines for disconnected field environments or defense facilities.

How do you avoid expensive Mapbox or Google Maps API tile bills?+

We generate self-hosted vector tiles (PMTiles or OpenMapTiles) hosted on cloud object storage (S3/Cloudflare R2), serving unlimited tile requests via CDN at pennies per gigabyte.
