Application Development

Custom, production-grade applications across desktop, web, and mobile — every surface built on a shared API, geoprocessing, and spatial-database backbone so data stays consistent no matter which application a user opens.

THE PROBLEM

Off-the-shelf GIS software wasn't built for how your teams actually work.

Every engagement is scoped across three delivery surfaces, chosen to match how a specific user group works: field crews need offline-capable mobile apps, engineering teams need desktop tools that integrate directly with CAD and structural-analysis software, and stakeholders need browser-based portals and dashboards accessible from anywhere — all on one shared API, geoprocessing, and spatial-database backbone.

WHAT WE DELIVER

Scannable scope, no mystery line items.

01

Delivery surfaces & platform

One shared backbone under desktop, web, and mobile.

Desktop (ESRI, QGIS Customizations)

Native ArcGIS Pro add-ins (ArcGIS Pro SDK, .NET, Python) and QGIS plugins that automate geoprocessing, batch validation, and format conversion via ArcPy — integrating directly with PLS-CADD, PLS-POLE, SPIDAcalc, and O-Calc Pro APIs, extending to 3D digital-twin authoring.

Web Apps

Enterprise-grade interactive web applications and dashboards built with React, Next.js, and the ArcGIS Maps SDK for JavaScript — including PWA offline patterns, AI copilot interfaces, and in-browser 3D digital-twin viewers with CesiumJS and WebGL.

Mobile Apps

Offline-capable field apps built with Flutter, React Native, and the ArcGIS Maps SDK for Native Apps, with high-accuracy GNSS, AR overlays for buried/overhead assets, and on-device AI (TensorFlow Lite, Core ML) that flags defects the moment a photo is captured.

Big Data Analytics

Large-scale processing and analytics pipelines over infrastructure and geospatial datasets, surfaced through ArcGIS Dashboards and executive reporting — pattern detection and predictive insight, not static reports.

Automation with AI/ML

On-device and cloud AI/ML for defect detection, GeoAI feature matching and classification during conflation, and automated QA/QC — cutting manual review across the engineering and geospatial pipelines.

Product Development

End-to-end product builds — architecture, UX, and deployment — hosted on Docker/Kubernetes and AWS/Azure with CI/CD delivery.

Custom Software Solutions

Bespoke software tailored to your workflows and integrations, built on the same FastAPI/Django REST, GraphQL, and Node.js backend shared across every Spatial Alphabet product.

HOW AN ENGAGEMENT RUNS

Four steps. QC gates at every one.

01DISCOVERY

We map the workflow, the users, and the systems the application must live between.

02PROTOTYPE

A working slice in weeks — real data, real devices, real feedback before full build.

03BUILD & INTEGRATE

Iterative delivery on a shared API/geoprocessing/spatial-DB backbone, with automated testing.

04OPERATE

Cloud deployment, monitoring, and a support path that doesn't end at launch.

PILOT PROGRAM

Scope a pilot for application development.

Scope a Pilot →

Paid or pro bono — your call. We take a real slice of your program, deliver it to production standard, and you evaluate the result before committing anything further.

01 — SCOPE

We define a bounded, representative work package with you — real data, real specs, one to three weeks.

02 — DELIVER

Our dual-shore team executes under the same QC protocol as a full engagement. No demo-grade shortcuts.

03 — EVALUATE

You audit the deliverables against your own acceptance criteria. Then decide — with evidence, not promises.
