Parcel viewers for local government

Your parcel data, on a map your whole office will actually use.

GeoParcels turns your tax-roll and parcel data into a fast, modern web map — one platform, three interface styles, tailored to how your office works. From Geographic Computer Technologies, mapping Louisiana government since 1994.

Atlas viewer in dark mode: a parcel map with a selected parcel highlighted and a details panel showing owner name, parcel ID, centroid, and area

One platform. Your choice of interface.

Every GeoParcels site runs on the same parcel data and the same fast map engine. What changes is the interface — pick the one that fits how your office works, and we tailor it from there. Same data underneath, a front end your staff will actually like.

  • Fast, modern maps

    GPU-rendered vector tiles — no plugins, no waiting.

  • Works anywhere

    Desktop, tablet, or phone in the field.

  • Built for your office

    Choose an interface, then customize.

Live LaSalle Parish demos

Three interfaces. Pick the one that fits.

Classic viewer: aerial imagery with a top toolbar and a layers panel listing parcels, sections, subdivisions, and districts with per-layer opacity sliders

Classic

The familiar classic-style layout your staff already know: a top toolbar, a layers panel with per-layer opacity, and a clean identify popup. Zero learning curve for offices coming from a legacy GeoPortal.

  • Top toolbar
  • Layers + opacity
  • Identify popup
  • Measure / draw / print

Modern viewer: a light topographic parcel map with an icon rail and a layers flyout controlling labels, roads, and features

Modern

A streamlined, panel-driven interface: an icon rail opens focused tools, results dock to the side, and map controls stay within reach. Denser and faster for staff who work in the map all day.

  • Icon rail + flyouts
  • Docked results
  • Owner / parcel + spatial search
  • Topo & imagery basemaps

Atlas viewer in dark mode: an edge-to-edge parcel map with a floating tool dock and a slide-in details panel for the selected parcel

Atlas

Our clean-sheet design: a floating command dock keeps the map edge-to-edge, details slide in from the side, and it works as well on a phone in the field as on a desktop — with a real dark mode.

  • Map-maximal dock
  • Slide-in details
  • Mobile-first
  • Light & dark
