Web GIS & Geospatial App Development
Custom web GIS — interactive maps, dashboards, client portals and screening apps, on ArcGIS Online or 100% custom apps backed by PostgreSQL/PostGIS.
About this service.
We design and develop geospatial platforms that put spatial data to work online. Depending on your needs we deliver on SaaS GIS — ArcGIS Online and the ArcGIS Developer platform — or build 100% custom applications backed by PostgreSQL/PostGIS databases.
That spans interactive web maps, geospatial dashboards, client portals, data-collection apps and screening applications, as well as asset-management and monitoring portals. Current initiatives include the Cartolytic Mapping Platform, the AGROGIS agriculture intelligence portal, and custom GIS applications for infrastructure and environmental clients.

Why Cartolytic.
- SaaS or fully custom — chosen for your needs, not ours.
- Geospatial and software engineering in one team.
- Built on a real spatial database (PostGIS), not just static maps.
- End-to-end: data → platform → deployment.
Frequently asked questions.
Do you build on ArcGIS or custom?
Both — ArcGIS Online/Developer when it fits, or 100% custom apps on PostgreSQL/PostGIS.
Can you build a client portal?
