Help & Documentation

Quick Start

Load a file — drag & drop a Shapefile (.zip), KML, KMZ, GeoJSON, CSV, or Excel onto the map or the Layer panel, or click Browse in the drop zone.
Manage layers — loaded layers appear in the left panel. Toggle visibility with the eye icon, reorder by dragging, click the palette icon for style options.
Identify features — activate the Identify tool (key I) and click any feature to view all its attribute fields in a popup.
Access tools — use the Smart Toolbar dropdowns at the top (Navigate / Inspect / Draw / Analysis / View) or click All Tools to open the floating toolbar.
Measure & analyse — measure distances or areas, run a buffer analysis, draw your own features, or generate an elevation profile.
Switch basemap — click the basemap switcher at the bottom-right of the map to choose Satellite, Street, Terrain, or Topo.
Export & print — export layers via Ctrl+E or print a formatted map with title, legend, north arrow, and scale bar via Ctrl+P.

Workflow Examples

Load & Style a Shapefile

Drag a zipped Shapefile onto the map → click the colour swatch in the Layer panel → adjust fill colour, stroke, and opacity in the Style Editor.

Measure Distance or Area

Activate Inspect → Distance or Area → click points on the map → double-click to finish. The result appears in the map.

Create a Buffer Zone

Activate Analysis → Buffer → click any feature on the map → set ring distances and unit → view intersecting features in the results panel.

Compare Two Layers

Activate Analysis → Swipe → assign Target and Overlay layers → click Activate → drag the vertical divider to compare.

Elevation Profile

Activate Analysis → Elevation Profile → draw a line along any route → the terrain cross-section chart appears at the bottom of the map.

Print a Map

Press Ctrl+P → configure title, font, colour, paper size, and layout elements → click Print Map to open the browser print dialog.

§1 — Navigate

Pan P — drag the map to move the view.
Zoom In / Out + / − — scroll wheel or toolbar buttons.
Home H — reset to the default map view.
Fit All F — zoom to the extent of all loaded layers.
Go to Coordinates — enter a lat/lng or place name to fly the map to that location.
Map Bookmarks M — save and recall named map views across sessions.
Terrain T — toggle a hillshade overlay for topographic context.

§2 — Load Data

Supported formats: Shapefile (.zip with .shp / .dbf / .prj), KML, KMZ, GeoJSON, JSON, CSV (with lat/lon columns), Excel (.xlsx / .xls).
Drag & drop onto the map canvas or directly onto the Layer panel.
Browse button — click the drop zone in the Layer panel to open a file picker.
WMS / WFS — use the Add WMS/WFS button in the header to connect to external map services by URL.

§3 — Inspect & Query

Identify I — click any feature to see all its attribute fields in a popup.
Query Builder Q — filter features by attribute conditions (e.g. population > 1000); matching features highlight on the map.
Attribute Table — view all features in a scrollable table; click a row to zoom to that feature.
Coordinate Picker — click anywhere on the map to capture and copy precise coordinates.

§4 — Measure

Distance D — click points along a route; double-click to finish. Result shown in metres or kilometres.
Area A — click polygon vertices; double-click to finish. Result shown in m², km², or hectares.
Press Backspace during drawing to undo the last point.

§5 — Draw & Annotate

Draw Point / Line / Polygon — place features on the map. Drawn features can be exported as GeoJSON.
Annotate — click the map to place a text label; double-click a label to delete it.
Vertex Edit V — drag the vertices of loaded polygon or line features to reshape them.
Ctrl+Z to undo and Ctrl+Y to redo drawing steps.

§6 — Analysis

Buffer — click a feature, set one or more ring distances; view features that intersect each ring.
Clip / Intersect / Union — apply geoprocessing between two loaded polygon layers.
Spatial Join J — transfer attributes from one layer to features it spatially intersects.
Spatial Select S — drag a rectangle to select features across all visible layers.
Swipe Compare — drag a vertical divider to compare two layers side by side.
Elevation Profile — draw a polyline; the chart shows terrain elevation along the line (SRTM ~30 m resolution).

§7 — Magnifier

Activate from Inspect → Magnifier or the All Tools panel.
Hover the cursor over the map to see a circular magnified view at a higher zoom level.
Use the layer toggle in the magnifier badge to switch the inner map's basemap independently.

§8 — Export & Print

Export Ctrl+E — save layers as GeoJSON, KML, CSV, or Shapefile (.zip).
Print Ctrl+P — configure title (font, size, colour), paper size, orientation, north arrow, legend, and scale bar, then click Print Map to open the browser print dialog.

Architecture

Geoinfinity Portal is a pure client-side single-page application. No server is required — all processing (file parsing, geoprocessing, exports) runs in your browser using Web Workers for heavy operations.

Map engine: Leaflet 1.9.4
Spatial ops: Turf.js 6 (via CDN + local fallback)
File parsing: shpjs 4.0.4, @tmcw/togeojson, SheetJS 0.20.2, JSZip 3.10.1
Drawing: Leaflet.draw 1.0.4
Clustering: Leaflet.MarkerCluster 1.5.3
Heatmap: Leaflet.heat 0.2.0

Supported File Formats

Format	Extension	Notes
Shapefile	.zip	Must contain .shp, .dbf, .prj
KML	.kml	Supports placemarks, paths, polygons
KMZ	.kmz	Compressed KML archive
GeoJSON	.geojson / .json	RFC 7946 compliant
CSV	.csv	Must have lat/lon or latitude/longitude columns
Excel	.xlsx / .xls	Must have lat/lon columns in first sheet

Privacy

Geoinfinity Portal processes all data locally in your browser. No files, coordinates, or attribute data are ever sent to any server. The application works fully offline once the page is loaded.

FAQ

Does my data get uploaded to a server?

No. All processing is 100% local in your browser. No files, coordinates, or attribute data are ever sent anywhere.

What file formats can I load?

Shapefile (.zip), KML, KMZ, GeoJSON, CSV (with lat/lon columns), and Excel (.xlsx / .xls).

How do I save my work?

Export layers via Ctrl+E. Use Map Bookmarks (M) to save named map views that persist across sessions.

Can I use the portal offline?

Yes, once the page is loaded. All tools work offline. Basemap tiles require an internet connection to display.

How accurate is the Elevation Profile?

Elevation data is sourced from Open-Meteo using SRTM data at approximately 30 m resolution.

Can I load more than one file?

Yes — load as many layers as needed. Each appears as a separate entry in the Layer panel with its own style, visibility, and export controls.
