GIS development

GIS development services

For 17 years I have turned geographic data into web maps, services and applications that can be maintained over time.

Geoportals and web map viewers

Interactive maps to publish your geographic information, with layers, filters, queries, measurements and downloads. I design the interface so anyone can use it.

For
Public agencies, NGOs, consulting firms and companies with geographic data.
Includes
Interface design, development, integration with your WMS/WFS services or databases, deployment and training.

Territorial atlases and story maps

Chapters with maps, charts and text that explain risk, vulnerability, biodiversity or climate scenarios to the public and to decision makers.

For
Governments, environmental and climate change programs.
Includes
Story script, symbology, chapter viewers, scenario comparers and deployment.
Stack
Leaflet · GeoServer · WMS

Spatial data infrastructure

I organize and publish your data: well-indexed PostGIS databases, OGC services with GeoServer, tile caching and migrations from shapefiles or geodatabases.

For
Teams with scattered data or slow map services.
Includes
Data model, bulk loading, spatial indexes, WMS/WFS/WMTS services, SLD styles and documentation.
Stack
PostgreSQL/PostGIS · GeoServer · MapProxy · QGIS

Map apps and PWAs

Phone apps that install without going through the app stores. They include points of interest, navigation and field data collection, and they work with a weak signal.

For
Tourism, mobility, fieldwork and on-the-ground services.
Includes
Mobile design, 2D/3D map, routing, manageable content and deployment.
Stack
Mapbox GL · PWA · KoboToolbox

GIS integrated with workflows

For organizations that handle cases on the ground. Each report is placed on the map, assigned to someone and measured on dashboards.

For
Municipalities, universities, gated communities and help desks.
Includes
Urbidata platform configured for your organization, or custom development.

Spatial analysis and cartography

Georeferencing, geoprocessing, territorial indices and thematic maps ready for reports or publications.

For
Studies, territorial assessments and research projects.
Includes
Processing in QGIS/ArcGIS or Python, map outputs and reusable layers.
