Introduction To SenseHawk Terra
Terra is a GIS, design automation, and data management platform that enables developers to manage multiple development projects and sites by providing preliminary site evaluation and design topography options. Industry professionals can use Terra to transform real work scenarios into digital assets by capturing, analyzing, and visualizing their project environment on a map-based interface.
Key Concepts & Methodology
Below are the steps followed while using Terra to reduce the complexity of terrain analysis.
The features of a product or service can say a lot about its valuable benefits however, your end goal is always to solve a problem or meet a need with the product or service in hand. Let’s have a look at all that’s in it for:
A. Asset Manager
Digitalize & organize asset data and processes
Your asset generates a huge amount of data across the lifecycle - SCADA data, terrain maps, design documents, contracts, component information like serial numbers, warranty documents, site activity-related data, and more. Capturing, organizing, and storing this data to facilitate quick retrieval and advanced analytics is a challenge. SenseHawk tackles this challenge using a combination of drone data analytics and workflow applications Terra, Work, Files, and Senshawk App to capture and organize data around a Digital Twin of your solar asset. This mode of data collection and organization enables the creation of a solar plant's machine learning-based comprehensive performance models. The result - is considerable improvements in productivity and improvement in asset returns.
B. O&M Manager
Increase generation and manage plant health
A solar plant has many discrete components - panels, combiner boxes, and inverters that should ideally be monitored periodically for performance and health using thermography. But conducting thermography of so many discrete components, analyzing the data, acting on it effectively, and storing it to capture trends over time requires specialized software. SenseHawk applications Therm, Work, and Sensehawk App effectively address this problem for you. Our solutions enable you to:
● Process large number of thermal images easily
● Detect and classify hotspots automatically with AI algorithms
● Visualize hotspots on maps of the plant with overlaid string and table numbers
● Use App for investigation and for taking corrective actions on site
● Create work orders instantaneously from the field using Tasks
● Collaborate with multiple stakeholders seamlessly
● Analyze trends over time automatically
C. Land Developer & PV Engineer
Streamline land development
Sourcing, evaluating, and managing land parcels for solar projects is a cumbersome task. SenseHawk applications Terra, Files, and Sensehawk App help ease the burden. Our solutions enable you to:
● Manage all sites through an easy-to-use cloud-based GIS-enabled interface
● Visualize sites in low resolution (Google Maps) or high resolution (Drone Data)
● Measure site contours, levels, grading requirements, and hydrology characteristics
● Detect unique terrain features using AI-based analytics
● Capture land documents and other sites related information tagged to site features
● Use App to view a site on a mobile device, add comments, capture additional pictures &
features of the site while walking on your site
● Share site information seamlessly with design teams, contractors, and lenders through a
D. Project Manager
Manage construction more effectively
As a construction manager, keeping track of progress and construction quality across a large solar site spanning hundreds of hectares is daunting. SenseHawk applications Terra, Files, Work, and Sensehawk App makes it easier by leveraging Artificial Intelligence and Drone technology to provide unprecedented visibility to your construction site and enable you to
manage construction effectively through an easy-to-use web interface. Our solutions enable you to:
● Visualize site status clearly with high-resolution orthomosaic maps
● Detect important features automatically with AI algorithms
● Measure quantities, alignment, levels, and dimensions with high accuracy
● Access critical documents on-site and off-site easily and intuitively using Files
● Use App to view the sitemap on a mobile device, access documents in the field, fill out
checklists and punch lists, and much more
● Create work orders from the field using Tasks
● Collaborate with multiple stakeholders working on the site with a single version of the truth
● Generate as-built vs. design comparison as a record of reference for contracts as well as
E. Lender & Insurance Provider
Conduct quick diligence on solar assets
Conducting diligence of solar assets can be daunting - drones can deliver high-quality physical asset diligence with a short turnaround time. SenseHawk applications Terra, Therm, Work, and Sensehawk App help ensure rapid on and off-site diligence, combined with analytics and reporting. Our solutions enable you to:
● Get accurate as-built and current state of the plant with a high-resolution visual scan
● Accurately confirm DC capacity with ML-based image analytics
● Conduct thermal scans and analytics to detect PID and other panel health issues
● Assess post-construction contours and related drainage/hydrology characteristics
SenseHawk uses photogrammetry to generate 3D surfaces and terrain maps. Photogrammetry involves collecting overlapping aerial photographs of an area, which are then analyzed for standard features in the area of overlap. Since the exact location and orientation of the camera are known at the time of capture of each image, the XYZ locations of the common land features/ points can be precisely determined. These are used to construct a 3D point cloud, generating a 3D surface and a color orthomosaic map. Below is a broad overview of the photogrammetry process.
FIG 1: OVERVIEW OF THE PHOTOGRAMMETRY PROCESS
With the help of RTK (real-time kinematic) equipped drones and adequate ground control, 3D surfaces generated by this method will have accuracies of up to +/- 1 cm (0.4 inches). In most cases, the accuracy levels exceed those obtained from more traditional methods like LiDAR.
Additionally, SenseHawk's proprietary terrain filtering process removes extraneous objects such as vegetation, buildings, farm machinery, and so on from the surface model, giving an accurate picture of the bare-earth terrain.

Measuring Elevation Profile
An elevation profile is the description of a two-dimensional, cross-sectional landscape view. It provides a side view of a terrain elevation along a line drawn between locations on the map.
1. Click on the line string tool from the toolbox on the right side of the map. Draw a line across any part of the map for which you would like to check the cross-section elevation.
FIGURE 4: LINE STRING TOOL
2. Click on the line drawn and select 'Elevation Profile' from the toolbox.
FIGURE 5: ELEVATION PROFILE
3. In the elevation profile dialog box, set the parameters. Choose the method as 'Line' and interval as '1m' or lower. Set the layer as 'DSM' and click on 'Calculate Elevation'.
FIGURE 6: STEPS TO MEASURE ELEVATION PROFILE
Measuring Spot Elevation
Spot elevation, or the elevation of a point on a map or chart, is used to indicate points higher than their surroundings. Spot elevation displays the actual elevation of a selected point and the top and/or bottom elevation of elements with a thickness.
1. To check spot elevation, select the marker tool from the toolbox and place it on the desired point on the map. Then select 'Elevation Profile' from the toolbox.

Volume calculations give accurate results for the volume of an area. The area of cutting and filling is found for each section with the polygon method or net area calculation method. The volume is determined by multiplying the average area with the distance between sections.
1. To begin calculating the volume of an area, select the polygon tool from the toolbox and draw the area on the map.
FIGURE 10: POLYGON MARKER TOOL
2. Click on the area and select 'Elevation Profile' from the toolbox. Select the method parameter as 'Base Height' and layer as 'DSM' in the dialog box.
