Data & GIS
GIS and Mapping Application Development
Spatial data turned into applications people actually use, not a static map image.
What is gis & mapping solutions?
A GIS web application lets people query and act on location data in a browser: which assets fall inside a boundary, which route is shortest, how a value varies across a region. RegalBit Solutions builds GIS applications with CesiumJS, PostGIS, Leaflet and Mapbox, and has delivered a full satellite imagery ordering platform with polygon drawing, KML and KMZ processing, vendor tracking, area restrictions, a wallet system and payment integration.
This is genuine specialist work and it is rare in this region. Our founders have been handling geospatial data since well before RegalBit, including GIS web interfaces and KML, GeoJSON and polygon geometry processing for government and enterprise clients at IDS Infotech, and the experience shows in the parts of a GIS project that are easy to get wrong.
The technical core is PostGIS, the spatial extension for PostgreSQL. It lets you ask real questions in SQL, such as which points fall within this polygon or what lies within two kilometres of this route, with proper spatial indexing so the answer returns in milliseconds rather than minutes. The alternative, loading everything into the browser and computing there, stops working at a few thousand features.
On the browser side we build with CesiumJS where the work is three dimensional or globe scale, Leaflet for lightweight interactive maps, and Mapbox or MapLibre where vector tiles and very large datasets demand it. The engineering challenge is almost always performance: rendering fifty thousand features without freezing a mid range phone requires clustering, tiling and simplification chosen deliberately.
Projection and coordinate system handling is where most GIS bugs originate, and they are expensive to find late. We get the SRIDs right at the schema stage.
Deliverables
What we build
Interactive mapping applications
Browser based maps with layers, filtering, search, drawing tools and export.
Drawing and area selection
Polygon, point and rectangle drawing on CesiumJS or Leaflet, with area restrictions and validation.
Spatial databases
PostGIS schema design, spatial indexing, projection handling and tuned spatial queries.
Data pipelines and conversion
Shapefile, KML, KMZ, GeoJSON, GPX and CSV ingestion, cleaning, reprojection and validation.
Asset and fleet tracking
Live location ingestion, historical playback, geofencing and alerting on entry or exit.
Spatial dashboards
Heatmaps, choropleths, clustering and time series playback for decision makers.
Process
How a gis & mapping solutions project runs
Written scope and a fixed quote before anything is built, then visible progress at every stage.
- 1
Understand the data
Formats, projections, accuracy, update frequency and volume. Projection mistakes cause most GIS bugs and are cheap to prevent early.
- 2
Model
A PostGIS schema with correct geometry types, SRIDs and spatial indexes.
- 3
Build
Map interface, layers and query tools, with performance budgets set for the target device.
- 4
Optimise
Vector tiling, clustering and geometry simplification so large layers stay smooth on a phone.
- 5
Deliver
Deployment, a data refresh pipeline, documentation and training for your team.

Who this is for
You will get the most from this if…
Imagery and survey platforms
Users need to draw an area, order data for it, and have the request validated and tracked.
Logistics and field service operations
Vehicles, technicians or deliveries to track, route and geofence.
Infrastructure, utilities and real estate
Plots, assets or networks that must be visualised and queried against boundaries.
Engineering rates
What this costs
We publish a rate band rather than a project price, because a project price without a scope is a guess. Once we understand the work we convert it into a fixed written quote, so you carry no open ended risk.
GIS & Mapping Solutions
From $18 / hour
Typical band: $18 to $40 per hour
GIS is specialist engineering and priced accordingly. It is also the area where the gap between an experienced team and an inexperienced one costs the most.
Why us
What makes this different from the other quote you are getting
An eight person engineering team, with a dedicated designer and a dedicated tester, shipping production software since 2017. The person who scopes your project is the person who builds it.
- Very few firms in this region offer genuine GIS engineering. We have built spatial platforms, not embedded a map widget.
- PostGIS first: the analysis happens in the database where it is fast, not in JavaScript where it is not.
- CesiumJS experience in production, including polygon drawing, KML and KMZ processing and vendor imagery tracking on a live commercial platform.
- Projection and coordinate system handling done correctly from the start, which prevents the most expensive class of GIS bug.
Questions
GIS & Mapping Solutions, frequently asked questions
PostGIS is the spatial extension for PostgreSQL. It adds geometry types, spatial indexes and hundreds of spatial functions, so a question like which of these ten thousand assets fall inside this boundary is answered by the database in milliseconds. Doing the same work in the browser stops being viable at a few thousand features.
Yes. Shapefile, GeoJSON, KML, KMZ, GPX, CSV with coordinates and direct database connections are all standard inputs. We validate geometry, fix invalid polygons, reproject to a consistent SRID and load into PostGIS.
CesiumJS when the work is three dimensional or globe scale, such as satellite imagery ordering. Leaflet when the map is two dimensional and the dataset is modest; it is lightweight and free. Mapbox or the open MapLibre when vector tiles and very large datasets are involved. We choose on your data and budget and explain the trade off.
Yes. GPS ingestion, live positions, historical playback, geofence entry and exit alerts, and reporting on distance, idle time and stops.
