About this app

[LEGACY VERSION - NO LONGER UPDATED]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.

Ratings and reviews

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!

Hi I really liked using the alignment viewer, especially the fact that I could take pictures at chainages. 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!

Great idea, really useful to have onsite, but constantly crashing on my Samsung. Camera takes about 4 days to open. Sometime it's easier to close and restart the app after each photo taken inorder to make it work. no one on with an iPhone have these problem please can this be fixed.
