Meridian GIS

Meridian 1.2 adds raster and terrain, a time slider, expressions, spatial statistics, a field collection kit, scan-and-handwrite input, coordinate formats, and deeper Siri, Shortcuts, and widget support. RASTER AND 3D TERRAIN Import GeoTIFF rasters as map layers with rendering presets — hillshade, slope, and colour relief. Turn on 3D terrain with adjustable exaggeration and see your vector data draped over a real land surface. TIME SLIDER Layers with date fields can be animated through time. Scrub the slider or press play to watch your data change, and export the current moment as a normal view of the layer. EXPRESSIONS Author labels, colors, selections, and calculated fields with expressions — field references, arithmetic, string and date functions, CASE WHEN, and geometry measures like area and length. A shared editor with live validation and preview backs all of them. SPATIAL STATISTICS New analysis tools join the set: hot spot analysis (Getis-Ord Gi*), IDW interpolation to vector grids, Voronoi diagrams and Delaunay triangulations, and spatial binning with counts and field aggregates. FIELD COLLECTION KIT Guided capture records GPS-averaged points and streamed lines and polygons straight into a layer's own form. With Meridian Pro, tracks can keep recording in the background with a Live Activity on the Lock Screen, and geofence alerts notify you on arrival at places you flag. SCAN AND HANDWRITE INTO FIELDS Tap Scan beside a text field to read a printed label, serial number, or barcode with the camera — only the text you tap is kept, nothing is stored or uploaded. On iPadOS 27, write into text and number fields and markup notes with Apple Pencil; recognition runs on the device and the result goes through the same validation as typing. COORDINATES AND ELEVATION Show positions as decimal degrees, degrees-minutes-seconds, degrees-decimal-minutes, UTM, or MGRS everywhere — the readout, bookmarks, the inspector — and paste any of them into Go To. With 3D terrain on, the readout and the Pencil hover card show the ground elevation. BUFFER DIRECTION AND EXPRESSION FILTERS Buffer inward, outward, or keep only the ring between. Select features with an expression, then keep that expression as the layer's definition filter with one tap. APPLE-NATIVE SURFACE Quick Look thumbnails for .gispad projects, Spotlight search, App Shortcuts for opening projects, running workflows, and exporting briefs, a recent-projects widget you can now pin to one project, and Apple Pencil hover previews on the map canvas. On iPadOS 27, workflows run from Shortcuts report progress instead of stopping at 30 seconds, and Siri can open the project you are looking at. Squeeze Apple Pencil Pro to open a tool palette at the pen. Swipe layer and table rows for Zoom To and Delete, and drag layers with the system's own reordering. COMMAND PLANNER WITH APPLE INTELLIGENCE On devices with Apple Intelligence, the Command panel can let Apple's on-device model read your request before Meridian's planner builds the plan. The model only proposes; the same deterministic planner validates it against your real layers, nothing leaves the device, and nothing runs until you confirm. Turn it off any time in Settings. GPX IMPORT AND EXPORT Bring GPS tracks in from Garmin, Gaia, Strava, and other GPX sources — waypoints, tracks, and routes import as their own layers. Export line and point layers to GPX, and share a track straight to GPX right from the field, before you even save it. MORE ANALYSIS TOOLS Points to Line, Multipart to Singleparts, Singleparts to Multipart, and Extract Vertices round out geometry conversion. Spatial Autocorrelation (global Moran's I) and Mean Center & Directional Distribution add two classic distribution statistics. FIND AND REPLACE Find and replace text in a field, with a before/after preview. IDENTIFY AND LABEL NUMBERS One tap lists every layer's features and raster values under it. Label numbers with separators, decimals, and units.
