Description
[LEGACY VERSION - NO LONGER UPDATED] Save time with Alignment Viewer – Import a rail or road alignment and receive real-time chainage / station and offset position information.
Designed to assist highway and railway construction / maintenance perform quick and easy site inspections to identify and report on site issues and progress from the field. Photos watermarked with chainage / station and offset ensure reports are prompt, accurate, and BIM compliant making this the perfect app for the modern Civil Engineer.
Import and view geometric lines, points and explore cross sections drawn from provided design and ground level data. Convert between geodetic WGS84/ETRS89 world coordinates (Latitude Longitude) and Cartesian Easting Northing based on thousands of available grid transformations with an optional site shift and scale factor.
****Alignment Viewer Features****
Please find below the full list of features provided by Alignment Viewer:
**Road / Rail Alignments**
Import alignments from LandXML (.xml), or NRG Alignment format (.nst). Provides support for road and rail alignments incorporating Curves, Spirals, Clothoids, Parabolas, and Straights. Real-time position updates in Chainage / Station and Offset. Take photos watermark with Chainage / Station and Offset.
**Geometric Pins / Points**
Allows the import of pins from Google Earth files (.kml), NRG Ground Plot Files (.gpf) and ASCII/CSV files (.txt). Pins can be manually placed based on geodetic, Cartesian or geometric alignment coordinates. Allows for editing of imported pins. Allows for the export of new pin files (.kml, .gpf, or .txt).
**Geometric Lines**
Lines can be imported from Google Earth files (.kml). Lines can be loaded to the map, loaded to the cross section or loaded to both. Cross section display color can be selected for each line file. Provides support for loading multiple line files at once.
**Watermarked Photos**
Photos can be taken which will then be watermarked with the Chainage / Station and Offset of the current location.
**Cross sections**
Allows the creation of a cross section perpendicular to a given geometric alignment or heading. Cross section updates in real-time. Cross section mode supports pausing updates, locking scale / transformation and importing Google ground elevation data.
**Landscape mode**
Perfect for placing on your vehicle dashboard NRG Alignment Viewer landscape mode provides clear and real-time updates to the device position in terms of WGS84, Cartesian EN and Geometric Alignment (Chainage/Station/Meterage) coordinates.
****Configuration Options****
Alignment Viewer provides an extensive list of configuration options allowing the app to be tailored to your preference.
**Geometric Alignment Configuration Options**
Offset display formation: -/+ or Left/Right. Alignment distance: Chainage/Station/Meterage. Alignment format 10000/10+000/100+00 Decimal places display for Alignment/EN.
**Map Configuration Options**
Traffic display. Street, Satellite, and Hybrid map types. Cross-hair. Map scale bar. Units of measurements: Imperial/Metric.
**Cross Section Configuration Options**
Cross section centre: Mid-Point or User defined Offset. User defined scale section / Cross section distance. Vertical Exaggeration. Google Elevation segment distance Enable / Disable Scale bars.
**Watermarked Photo Configuration Options**
Watermark position Watermark size Show road / rail alignment name Show gps accuracy Show date Show time

Fantastic app saves you having to get the GPS out for rough locations currently using it on the M1, easy to use so trying to get this app rolled out on our project for all site personnel. It'd be great if you could take a photo (auto tags it with change and offset) and it creates a pin.

Fantastic app for all Roading and Rail Engineers a must-have

Excellent app from NRG. Perfect for our identifying issues on site. It gives accurate and clear information regarding position (coordinates/chain age/offset), which can be relayed back to the office. We are currently using this to pick up Snags, Health and Safety, and for site progress reports.

This was a great app, however on getting the galaxy S24, it no longer works as it needs access to folders that Samsung has restricted access to for security purposes. If there was a way to change directories in the app, then it would still function. Hoping for an update to fix!

After uploading the land XML the chain age and the offset still gives question mar “？？？” please assist

Hi I really liked using the alignment viewer, especially the fact that I could take pictures at chain ages. It was working fine on my work tablet until an error kept coming when I took pics. I ASSUMED this was my tablets issue, so I decided to purchase the app again onto my phone. Once downloaded the exact same thing happen. This app is heavily relied on at the project I'm working on, but I believe the updates caused this, none of my colleagues experiences the same issue. Please fix!
