Quick Start

This quick start guide will orient you to the basics of GeoSpatial Manager, including concepts, basic manipulation of the as-built model, and several key tools.

Overview

GeoSpatial Manager is the single source of truth for your digital as-built surface model. Users with upload permissions (typically surveyors) upload regular updates in the form of as-built surfaces that might cover only a portion of the site. GeoSpatial Manager incorporates each of these partial source surfaces into a single overall model. The model keeps track of the acquisition date and time of each source surface so that users can view the overall as-built surface for any given point in time between the initial and most recent surface uploads. All users see and query the same model. Each source surface remains identifiable and retrievable for download. Source surfaces can also be deleted so that they no longer contribute to the combined model. GeoSpatial Manager automatically and dynamically updates the combined as-built model in response to uploads and deletions so that the model always represents the best available information.

User interface

The image below shows the main user interface elements of the GeoSpatial Manager Home page.

Timeline	Use the timeline to set the selected surface, or define time ranges for tools that require it. See Selecting a surface in the timeline on this page for more information on using the timeline.
Tools	Change the surface visualisation, generate cut and fill reports, view the as-built in cross section, and export the combined as-built surface. See Changing the surface visualisation and Analysing the as-built model on this page for more information on these tools.
Surfaces list	View and manage the list of imported source surfaces contributing to the combined as-built model. See Source surfaces and the Surfaces list on this page for more information.
Polygons list	View and manage polygons and polygon sets used to identify areas of interest or as input for certain tools. See Creating polygons on this page for information on creating polygons.
Settings	Configure site settings, coordinate systems, users and roles, and other settings. See Global Settings for more information.

Interacting with the as-built model

The combined as-built model is displayed in an interactive 3D viewer. GeoSpatial Manager handles large, detailed surfaces easily. It does this by dynamically adjusting the level of detail shown based on the current view of the data, allowing smooth and responsive interaction.

Panning, zooming, and rotating

You can pan, zoom, and rotate your view of the as-built surface using the following controls, depending on whether you are using a mouse or a touch screen.

Operation	Mouse	Touch
Pan	Left click + drag	One finger drag
Zoom	Right click + drag, or Mouse wheel scroll	Two finger pinch
Rotate	Middle click + drag, or Ctrl + left/right click + drag	Two finger drag

The pan, zoom, and rotate operations are all based on the position of the mouse cursor on the screen (or the position of your fingers on a touch screen). This means, for example, that when zooming in, the view will keep the point under the mouse cursor as the focal point; when rotating, the view will rotate around the point under the mouse cursor. The following animation demonstrates panning, zooming, and rotating by positioning the mouse, clicking the left, right, or middle mouse buttons respectively, and dragging.

Source surfaces and the Surfaces list

The uploaded source surfaces contributing to the combined model are listed in the Surfaces list in the right-hand pane in descending date order; that is, the most recent source surface appears at the top of the list.

• Hover over a source surface in the list to show its boundary polygon in the combined as-built model.

  

• Perform actions on individual surfaces in the list using the tool buttons, including (Download surface) and (Generate polygon).

  

See Managing Source Surfaces for more information about the surfaces list.

Selecting a surface in the timeline

GeoSpatial Manager can display the combined as-built surface for any point in time between the oldest source surface and the most recent source surface. The timeline located at the bottom of the viewer represents each uploaded source surface with a triangle. The green triangle represents the current selected surface. The surface in the viewer is a model that combines each source surface from the oldest to the selected surface.

• Click on the timeline to pick a point in time and select the closest source surface. A blue position marker indicates the point in time that was picked. The date and time of the selected surface is shown in the bottom-left corner of the view. The viewer will automatically update to show the combined as-built at that point in time.

• Hover over the timeline and use the mouse scroll wheel to zoom the timeline in or out. Alternatively, right click on the timeline and drag the mouse left or right.

The current selected surface is also indicated in the surfaces list with a green triangle.

The animation below demonstrates clicking various points on the timeline to show the progression of a mining operation over time.

Changing the surface visualisation

You can change the visualisation of the surface model using the Colouring tool group located in the left pane.

The table below summarises each colouring tool. See Colouring for detailed instructions on the colouring tools, including how to configure colour maps for options that use them.

Monochrome	Apply a single colour uniformly to the surface.
Imagery	Display satellite imagery on the surface (requires internet connection).
Elevation	Colour the surface by elevation according to a configurable colour map.
Slope	Colour the surface by slope angle according to a configurable colour map.
Time since capture	Colour the surface based on the time elapsed since the latest data capture. This is useful to quickly identify which parts of the surface have not been updated recently and may require resurveying.
Elevation change	Colour the surface by the change in elevation over a specific time period. This colouring option is useful to quickly visualise which parts of a site have been subject to the most activity.
Contours	Apply contour lines to the surface at specified intervals.
Opacity	Make the current colouring method translucent, revealing the underlying surface imagery.

Analysing the as-built model

GeoSpatial Manager contains several tools to help you analyse and understand your data. Most of these tools operate on an area of interest defined by a polygon, so we will first look at how to create polygons in GeoSpatial Manager.

Creating polygons

There are three ways of creating polygons in GeoSpatial Manager: by digitising points on the surface in the viewer, by generating from a source surface boundary, or by importing from file. Manage polygons and polygon sets in the Polygons list in the right-hand pane.

The animation below shows how to create a new polygon by digitising point on the surface. Start by switching to the Polygons list and clicking the (Draw polygon) button. Instructions appear on the screen.

You can view any saved polygon by making sure its checkbox is selected in the Polygons list.

See Polygons for more detailed instructions on polygons, including generating from surface boundaries, importing from file, and combining into polygon sets.

Cross section tool

The Cross Section tool allows you to view the parts of the surface behind an intersecting vertical plane. You can opt to display the surface at a single point in time, or compare the surface between two points in time.

To use the cross section tool, on the Home tab, make sure the Cross Section tool is expanded. Then, simply select a polygon to define the region in which to display the model cross section, select a date range, and click Generate.

See Cross Section for more detailed instructions on using the cross section tool.

Cut and fill tool

The Cut / Fill tool allows you to calculate surface volumes and tonnages. There are two cut and fill methods to choose from, as follows:

• Elevation: Calculate the cut and fill volumes with respect to a specified reference elevation.

• Date Range: Calculate the difference in volume over a specified date range.

See Cut / Fill for detailed instructions on calculating cut and fill.

Point and distance queries

The viewer supports a couple of simple queries based on the geometry of the surface model. These queries are available from the tool buttons located in the top-right corner of the viewer and are described below.

	Query Point Query the location of a point clicked on the surface.
	Distance Query Query the distance and horizontal/vertical displacement between two points clicked on the surface.
