Set the project Coordinate Reference System
The accuracy and positional integrity of a Neara project depends on a correctly set project Coordinate Reference System (CRS).
If you have already imported LiDAR data with a spatial reference, the project will have a CRS set.
If you are starting from a new, blank project, configure the CRS manually by following these steps.
On the Toolbar, select the Survey tool:
The Survey options are displayed in the Properties panel:
Neara accepts European Petroleum Survey Group (EPSG) codes when configuring a project's CRS.
Click the Change link in the Spatial section:
Enter the EPSG code for the design, and click the Apply link:
Notice that coordinates are now displayed and updated in the lower-right corner of the Perspective view as you mouse around in it:
When sufficiently zoomed out, the spatial reference may automatically change to EPSG 3857 (web mercator) at which point calculation results should be ignored.
This attempts to automatically avoid graphical and precision issues that can occur when traversing very large distances or crossing coordinate system boundaries in the one project.
Use Google Maps Satellite imagery as the terrain overlay
To aid design and exploration, Neara can display Google Maps Satellite imagery (and more) on the terrain in the Perspective view.
In a new, blank project map tiles display a simple grid:
To turn on the default Google Maps Satellite as an overlay on the map tiles, first select that option in the Map Overlay section of the Survey tool properties:
At this point, the tile may remain blank. Complete the next step to set the correct location for the design, and load Google Maps Satellite overlays on the map tiles.
Neara also offers the ability to import and load captured high-resolution aerial and satellite imagery onto a project's terrain. Contact us for more information.
Set the design location
To the right of any group of tabs in the workspace, click the (+) icon to open the panel selector. On the popup, select Analytics Map:
The Analytics Map provides an interactive map experience to find locations, display the location and bounds of imported data layers (such as network models, point clouds, and other geospatial datasets), and navigate to locations in a project.
Note the arrow and distance shown. There is a relationship between the Perspective view, and the Analytics Map. This arrow indicates that the area currently displayed in the Perspective view is (incorrectly) positioned outside the map's bounds:
Click the blue arrow to jump to that location:
To set the Perspective view's location, search for and select a location in the Analytics Map Search bar:
When the correct area is in view, either:
right-click on the map at a location and select Jump to location on the popup menu, or
click on the map at a location
Neara will switch to the Perspective view, navigate to that location, and load a tile with the correct Google Maps Satellite imagery overlaid:
Increase or decrease the transparency of the Google Maps Satellite map overlay under the View menu:
To expand the number of tiles displayed, select the Move and select tool on the toolbar, and click the (+) icons in the Perspective view around the displayed tile. The Google Maps Satellite imagery will automatically load on each tile:
Modelling terrain
You can import and/or manually setup the terrain in your project. See Create a ground / terrain profile
