Selection requirements for tool to work
A dataset and at least one polygon layer
Our dataset statistics tool allows you to quickly extract summary statistics from raster data based on vector boundaries (just like Zonal Statistics in QGIS or ArcGIS Pro). This helps you analyze patterns, compare values across different areas, and generate insights for decision-making—whether you're assessing vegetation health, monitoring land use changes, or measuring terrain elevation variations.
To calculate summary statistics from one of your datasets, follow these steps:
Create one or more polygon layers representing the areas or features that you would like to summarize. Each layer can have one or more features within it.
In the table of contents, select your dataset of interest as well as your reference polygon layers (use the ctrl / cmd key to multi-select ToC items).
With the correct items selected, click the
calculate statisticsbutton on the top menu bar (can also access via toolbox > analysis > calculate statistics).Select the dataset layer you would like to summarize (choose between greenness index, DSM, DTM, height).
Click run
When the analysis is complete, you will see a graph and a summary table. The data layer (e.g. greenness index) that you have selected to calculate the statistics is listed at the top.
Understanding the graph
Click on the graph to expand it - this will make it easier to see and interact with.
The summary graph is a frequency histogram.
The x-axis (horizontal) represents the range of values in the data layer you are analyzing (e.g., greenness index).
The y-axis (vertical) shows the number of pixels from the datasets within the selected polygon area that have each corresponding value.
You can show or hide the results for each polygon layers on the graph by clicking their names in the legend.
Below the x-axis, an interactive 'focus slider' lets you adjust the graph to focus on a specific range of values. You can reset the focus to full range at any time.
Understanding the table
By default, the summary table is collapsed. You can expand and collapse individual statistics one at a time, or opt to expand / collapse all.
We calculate the following statistics:
Average
Standard deviation
Minimum
Maximum
Median
Pixel count
If you have selected the 'greenness index' layer, there will be no unit on any of the statistics.
If you have selected the DSM, DTM, or height layers, the statistics unit (e.g. m, ft) will be the same as your project unit (except pixel count will remain unit-less). If you would like to change your measurement units, follow these instructions.
Note that depending on the spatial resolution (GSD) of your input dataset the size of the polygons you can use with this tool will vary. If your data are very high resolution (i.e. captured at low altitude), you may not be able to calculate statistics for polygon areas larger than 1ha, particularly for the height layer.
