Description

Derived from our high-resolution DEMSA2, our viewshed product offers an accurate and detailed line of sight analysis solutions for your planning needs.

Use-Cases

Our viewshed product aims to provide critical planning information for agricultural, mining, energy and urban development applications.  Example applications include the following:

  • Modelling wireless internet coverage for an internet of things (IoT) system installation.
  • Predicting the visibility of planned wind turbines for an environmental impact study.
  • Evaluating potential sites for a telecommunications installation.

Placing an Order

When placing an order, please send an email to info@geosmart.space and provide the following:

  • A brief description of your use case, such that we have some context when conducting our analysis and provide additional support.
  • A set of points for which to conduct the analysis.  This can be provided as a geospatial point file or as a table in the following format:
y coordinate (latitude) x coordinate (longitude) Observer height (metres)
  • The target elevation for analysis.  This is an offset to be added to the surface model when conducting the analysis.  It can be helpful in cases where you are looking for a location to put up a signal mast of a specified height.
  • An analysis extent, either as a geospatial polygon or as a radius from the centroid of the provided points.
  • Your preferred product format(s).

Product Specification

Your GeoSmart viewshed product delivery can consist of any or all of the following:

  • A georeferenced visibility raster for use in GIS software or Google Earth.
  • A georeferenced line dataset (shapefile), indicating the visibility network for the provided points.
  • A pdf map consisting of the visibility raster, visibility network and DEMSA2 hillshade of your order area (example below).
