Hi, Just wanted to know if there's any way to use Cognite UI Apps instead of we developing custom UI App. If yes, could you please let us know the process and how to use it? 

We have identified a bug in the time series datapoints fetcher in the Python SDK which may cause duplicated timestamps to be returned. Affected versions are 2.47 through 2.51. Please check if you have anything deployed using the datapoints API in this version range. If you do, please upgrade to >=2.52 ASAP.https://github.com/cognitedata/cognite-sdk-python/blob/master/CHANGELOG.md

This is how it looks like when you push geospatial to the limit and show 4+ billion essential ocean variables (temperature, salinity, pH, oxygen etc) captured from 220,000 research cruises from 1890-YTD. Such data is very important to understand the effects of climate change, for instance ocean warming, deacidification, dead-zones (lack of oxygen), biodiversity migration and more. In the Ocean Data Platform, we have implemented something called the “Ocean Data Connector” which is a cloud-based JupyterHub infrastructure where you can analyze this data in a very efficient way.Ocean Data Platform and the “Explorer” interface 

On 8th March our amazing data scientists at HUB Ocean and Cognite gave a workshop at the Woman in Data Science (WiDS) event in Oslo. Have a look at the video and blog post. The data challenge was related to coral reef bleaching events applying open data on the Ocean Data Platform.Closing the gender gap in Ocean Science? — HUB Ocean | Dedicated to Unlocking Ocean Datahttps://www.linkedin.com/posts/hubocean_coralreefs-biodiversity-collaboration-activity-6928641478181154816-IImk?utm_source=linkedin_share&utm_medium=member_desktop_web

As we announced in our last release post, we recently updated our calculations backend to run on individual data points if the total count of data points is less than the predefined maximum limit.(You can watch the video walkthrough for more information.)When this improved functionality was released a few weeks ago, this limit was set at the intentionally low value of 10,000 individual data point

 Hello  @brendan Buckbee at Celanese has created a chart for the 12 month, but gets an error message. Is there any way that this can be created into a chart. I have attached a screenshot of the calcs. cc: @Kylie R

Hi, In the AIR application, one can choose to see the relevant time series for 5 years, 1 year, 6 months, 1 month, and “Custom”. When clicking “Custom”, a date choosing panel shows up. When selecting the end date, the application freezes, and one has to refresh the application to get it back. (Feilkode: RESULT_CODE_HUNG)  

Hi. How can I get aggregated values from synthetic timeseries fields on templates? Intuitively, I would expect the “datapointsWithGranularity” operator in the graphQL query to give me this, but I get the same results as for the “datapoints” operator. Should the aggregation type and granularity be part of the definition of the synthetic timeseries field in the template? If so, how? 

Hi! I’m curious what is the best practice to do this basic thing and visualize on Grafana ( ideally without code): With a flow transmitter, summarize the total volume per day or week.  Correct the above against a threshold or a running signal. Ie. I now when the flow should be 0Here’s how I do nr 1, it feels a bit like a hack. Nr2 I am solving with Functions in CDF, however it would be nice if there’s a quick way of doing it without code,  The query looks like this: 24*ts{externalId="arba:one:s=0:PLC_03!Vc_S07_200_FT01_PV", alignment=1653386400000}-Should the alignment be at the middle of the day, 12:00, or at midnight 00:00? When we get back to wintertime, it will be off by one hour..  

Hi, When parsing a large production model some high level concepts we want to filter on are structured as assets. I.e. a fiscal region for power in the Statnett case.  Our model is now hitting limitations of subtree queries. With more than 100k assets per region for some regions. What is your thinking around how to handle such cases in a model? To spike the conversation we’ve considered moving high-concept parts of the tree to labels, or making more of the DB type of operations locally. However, the former demands a pipeline for moving concepts suited for a tree  to a Label “just because”. The latter requires quite a lot of iron present on the local instance processing the query. An instance of the SDK quering we do can be seen in the power-SDK 

Hello, Today’s topic is about Cognite functions: Cognite functions enable the user to run and schedule arbitrary code to clean, process and do calculations on your data. They are easy to use and have seamless integration with Cognite Data Fusion (CDF), allowing the Cognite Function to interact with CDF directly. The service automatically scales the computing infrastructure to handle a fluctuating number of function calls.   They can be triggered on schedule, on click in the UI, and even with the experimental Python SDK, which makes them adaptable to a lot of use cases. 

After confirmation from @Geir Engdahl, is there any plans for developing models where application developers can attach data to users, like preferences or even work orders?

The best way to play around with Flexible Data Modeling in CDF is through Templates.  Please be aware of the following before getting started! Currently, the App Dev Journey team at Cognite is working on a new Schema Service that will replace Templates towards the end of 2022. For more details on the differences between Schema Service and Templates, go here.There will need to be a migration between Templates and Schema Service in the second half of 2022. The migration will be simple for the data modeling features and querying features as they will be both be using a GraphQL interface. However, mov

 Hello everyone! Nicklas from InField here 😊 It’s been about a month since we were on the grounds with the crew at Celanese, and the InField team has been hard at work analyzing, prioritizing and planning work going forward based on all the insights gained from the visit. The visit has been invaluable and we want to keep the momentum going full steam!While we’re working on delivering new functionality and fixing bugs, I just wanted to reach out and say a huge thank you to the awesome and helpful team at Acid South, that makes this possible – we learned so much from you and it was a blast to work together on the grounds and I am very hyped about our collaboration going forward! 😊 See y’all again soon, Nicklas on behalf of InField 

Introduction In this post we continue to share some of our internal material aimed towards solution builders, such as data scientists, who want to develop their ability to develop high quality solutions by creating more reliable, maintainable and readable code. This is the second part of 2.MotivationHigh code quality is easy to recognize but can be very hard to describe concretely. The assumed benefits are easier maintainability, modifiability, and more. While code style, like formatting, can be a matter of different taste, most parties agree that other code practices that fall under the umbrella term “anti-patterns” should be avoided. To stop endless formatting discussions and the like, having (and adhering to the industry) standard makes reading and understanding code across repositories easier.What this guide is not

The Cognite OPC UA extractor reads data from OPC UA servers and writes data to Cognite RAW, assets, time series, events, and relationships, depending on how it is configured.  Now, we’ve made the GitHub repository public. The extractor serves as a comprehensive example for using the .NET extractor utils, or as a baseline for developing custom applications working with OPC UA and CDF. The rep

I am doing some ETL jobs in Azure Databricks and have successfully managed to use Cognite’s Spark Data Source to read and write time-series, datapoints etc from and to CDF. I know that databricks itself is a cloud platform. However, it is interesting for me to be able to run some or all of the jobs locally during development phase. I wonder if it is still possible to somehow test-run Spark jobs locally? The configuration does not seem to be trivial.  I played a little bit with PySpark, and I was able to run it on my Mac but I could not create a connection to “cognite.spark.v1” to read or write data. Do you know if it is possible to perform such operation? If not, what would you suggest?  

Hello! I wanted to share a good infographic on how Industrial DataOps enables data product strategies. What is Data Fabric? What is Data Operations? What are Data Products?I was just at a Utility Analytics conference the other week in the US where this was a big topic of discussion- how to embed domain expertise in governed data products through joint ownership between the data product managers and the data product consumers. Several utilities are already formalizing these teams internally into a mesh-based architecture.Power Market Operations is a great example of how a data product s

Through 3D scanning technology, Cognite obtains accurate point clouds of large-scale industrial plants with a high level of detail. We're currently using these point clouds for visualization and measurement purposes to provide value to our customers.However, we're still missing a fundamental understanding of the objects located in a three dimensional scene. This understanding starts with semantic segmentation, the process of assigning each a class to each point in a point cloud. In the D-MVP and 3D team, we are currently working hard on solving this with state-of-the-art Deep Learning technology. Our goal is to automatically connect assets in a point cloud directly to Cognite Data Fusion, enabling rapid development of fully contextualized as-built digital twins.In the attached video you'll see what we are aiming to achieve: A point cloud from an industrial site, where all the points are split into different classes. Let me know what you think eller I'd love to hear you
