Welcome to Imageryst!
In these documents you will find general instructions to make the best use of your Land Analysis Core account. If you have any further questions, don't hesitate to write an email to micaela@imageryst.com.
General:
First, some general info:
Supported Formats
Georeferencing files: Imageryst supports KML/KMZ, GeoJSON, and DXF containing the polygon.
Download files: Imageryst supports Shapefile, KML, GeoJSON, CSV, and DXF. The maximum download size is 2GB of data.
Usage Recommendations
Check your internet connection before use. Imageryst does not currently have an offline mode. Project modifications might not save correctly if the connection is poor.
It's optimized for Google Chrome. Other browsers that work well: Opera, Edge, Brave. We do not recommend Firefox. The platform's performance may be diminished.
Available Data, Data Sources, & How We Process Them
Available Data Packages:
Land Analysis:
LiDAR-dependent algorithms. Dates may vary:
- Slope: Measures the slope in degrees of inclination and in %. It uses points. Imageryst provides the average, maximum, and minimum. This is a proprietary GDAL function.
- Radiation: Measures the average annual radiation per m² using points. We can see the total average for the area, as well as the maximum and minimum.
- Contour Lines: Measures altitude above sea level (m.a.s.l) via contour lines. We can see the total average for the area, as well as the maximum and minimum.
- Altitude: Measures altitude above sea level (m.a.s.l) via points. We can see the total average for the area, as well as the maximum and minimum. Data is extracted from LiDAR.
- Aspect: Measures the orientation of the area in degrees, using points. Imageryst provides the average in degrees. This is a proprietary GDAL function.
- Waterways: Shows you which areas are floodable, as well as the water's most likely course.
Ad-hoc algorithms, processed through a satellite image:
- Vegetation Health: Classifies the terrain based on vegetation density detected through NDVI.
- Burned Areas: Identifies m² of burned areas.
- Water Bodies: Identifies bodies of water, estimated depth, and area through NDWI.
- Soil Humidity: Classifies the terrain based on detected humidity through NDWI.
Through other sources (available data may vary depending on region):
- Roads: Identifies paved roads and some paths depending on the material. Provides m² of road.
- Lights: Identifies night luminosity intensity and types of lights. Classification through image values.
- Power Lines: Allows us to distinguish power lines.
- Solar plants: Detect registered solar plants.
- Wind plants: Detect registered eolic parks.
Interface and Managing Projects
There are 2 main tabs to use in our web app: the Projects tab and the Dashboard tab. ‘Projects’ will help you manage, delete and edit all your executed analysis. We will dive into the Dashboard tab in a following section.
User Configuration
Your User Profile
You can access your Profile through the dropdown menu on the right corner of the header. You can sync your account to ArcGIS, check how many km² you've consumed already, and deactivate/pause your account.
Syncing with ArcGIS
You can synchronize Imageryst data with your ArcGIS account. Each dataset is exported as an additional information layer. For this to work, you must enable synchronization with ArcGIS. Keep in mind that the session may expire and, if so, you will need to log back in.
Land Analysis
Create Projects
First, you'll need to name your project. Then, select the attributes you want to measure.
Next step: determine the area to analyze (the maximum area you can analyze will depend on your contracted package. If you need more area for a specific instance, please contact us).
With your own area file
Once you have chosen the attributes you want to measure, you can upload your own georeferenced file. Imageryst supports KML/KMZ, GeoJSON, and DXF containing the polygon. Important: it cannot be a polygonZ; the file must not include a Z coordinate.
Searching for the Area using the Builder.
Once you have chosen the attributes, you can use the map on the right to search for an area. Select "Draw" and draw the outline of the area you want to analyze, clicking each time you want to change the line. When you have finished marking the entire polygon you want to analyze, you can press "enter," and it will be drawn. Select "Continue."
Once a project is created, if it has not yet been executed, you must select the project on the Projects tab and click "Execute". Algorithms that have not been executed will not be visible on the dashboard. In case of errors or excessive loading times (anything over 15’) for dataset execution, please contact us.
Project Analysis
Our tool enables you to extract detailed information about the state of a specific parcel of land.
Results Cards and Their Functionalities
Share your results
To get the most out of Imageryst, we encourage you to use it as a collaborative tool. The Share tab enables you to download, export and share all the data in multiple formats:
FAQs
-
What if it’s cloudy in my selected area?
Sadly, clouds can be a major hindering factor in Satellite Monitoring, and it might interfere with results if very recent data is needed. More than 20% cloud coverage might present issues.
-
What if I want data that is currently unavailable?
Some data, such as LiDAR data for certain regions or specific dates for satellite data, might be restricted due to technological limitations. In such cases, contact us and we’ll try to find a tailored solution.
-
How long do I have to wait for the results to be processed?
A project should never take longer than 15’ to be fully processed once executed. In case of ad-hoc satellite image tasking, the normal waiting time is around 1-2hs, but it could take up to 3 days or longer, depending on the cloud coverage and desired resolution.
-
What are the maximum areas I can analyze?
For the initial plan of Land Analysis Core, the total monthly area is limited to 4km².
