I am an amateur to GEE, Can anyone help me the script to retrieve Common data for Sentinel-1, Sentinel-2, or Landsat-8 on the same study area?
I require all the three sensor's data for same-day in the same study area. This is for comparing and validating the sentinel-1'SAR data with optical data (sentinel-2 or Landsat-8). The script should return the dates of the common acquisition by satellites in the same study area.

I'm racking my brain how to use the Wikipedia API to get a list of the power plants in https://en.wikipedia.org/wiki/Category:Coal-fired_power_stations_in_the_United_States_by_state
Then include the data from the Commission Date field next to each plant. (Alternatively, cross-reference with the "energy infrastructure completed in 19XX" category)
Where do I start? EIA this information, but only for the actual generators that are still in use, not the date for the powerplants housing those generators. I also found some Data related to Co2 production, but those dates go back only to 1945.
Any help would be greatly appreciated!
How do I link my activities variable to only the corresponding KPIs variable?
Using guidance from a number of sources, but primarily the genius of Jeffery Shafer articulated through the SuperDataScience video, I built a Sankey Diagram for my work. For the most part it works, however, I have been trying to figure out how to adjust my Sankey Diagram model to line up each activity with ONLY the corresponding KPIs, but am having no luck.
The data structure looks like this:
You'll note I changed the binary value to "", 2 instead of 0, 1 as it makes visual calculations easier. For the "Viz" variable, I have "Activity" for the raw data set, then I copy/paste/replicate the data to mirror the data (required for the model) but with "KPI" for the mirrored data.
In the following image, you'll see my main issue is that the smallest represented activity still shows as corresponding to all KPIs when in fact it does not. I want activity to line up only with the corresponding KPIs as some activities don't correspond with all, or even any, KPIs.
Finally, here is the model very similar to what the above video link shows:
Can someone help provide insight into how I can adjust the model to fit activities linking only to corresponding KPIs? I appreciate any insight. Thanks!
I have a solution to the issue, thanks to a helpful Tableau support member named Anthony. It was in the data structure. The data was not structured to only associate "Activities" with their "KPI" values within Tableau's requirements, but every "Activities" value with every "KPI" value. As a result, to achieve the desired result, the data needs to be restructured to only contain a row for every valid "Activities" and "KPI" combination. See the visual below where data is removed to format properly:
-------------------------------------->
Once the table is restructured, the desired visual result should configure with the model. It works like a charm!
Good luck out there!
I had created the text semantic search engine. However, I cannot find the data set which is labeled so that I can evaluate the information retrieve of my system.
Is there any public available document (text) which is labeled. As I would need the text document to evaluate the information retrieve result. (recall, precision, F1 value...)
Thanks.
I do research in this direction. In all my research, i have used AOL dataset which consists of ~20M web queries collected from ~650k users over three months (March 01, 2006 to May 31, 2006). The data is sorted by anonymous user ID and sequentially arranged.
The data set includes {AnonID, Query, QueryTime, ItemRank, ClickURL}. More details can be found in the link mentioned above. I am interested to know how you have implemented and if possible, share your engine's code. I am also interested to know the performance on AOL dataset in your search engine.
You can find the dataset in my git repository. Thanks!
Sample are collected from patients. Depending upon the type of the sample, samples could have different properties/attributes. There is a list of 5 properties/attributes which are standard across all samples, but they can have 2 dynamic properties. These properties/attributes vary for sample types. I am trying to model this scenario.
Following is what i was thinking from a design perspective
Sample Dimension
Sample Fact (related to Sample Dimension table)
I have also created a table called Sample Properties which has a single row for a property of the sample.
Sample Fact and Dimension are 1 to 1. Where as Sample Dimension to Sample Properties is 1 to many.
I am really confused how can i model this scenario, so that if any one wants to look at sample properties they can do that. The sample properties won't be analyzed but will be just looked at.
I would really appreciate if someone can guide me with the design of the cube. If any more detail is needed please let me know.
I am trying to display a list of closest restaurants of a given city within a radius. In order to do this, I'll have to convert the city to a longitude/latitude.
When the user fills in his/her restaurant information, he/she will fill in the address. Based on that address i need to get a longitude/latitude and save that to the database.
I don't need to point this on a map. I'll be just displaying a list of all closest restaurants within the given radius to the user.
How can I do this with ASP.NET-MVC4?
Also, this project is based on Code First. And for address I have DbGeography as datatype set.
The project is kind of based on this tutorial
Edit
To avoid anyone else telling me this is not possible with ASP.NET on it's own, I am aware of that. an example with Google maps / .NET wrapper would be great.
This query itself is typically done in the database back-end because the program is the consumer of the data not the keeper of the data. You will have a table of restaurants, possibly for many cities, each restaurant having a latitude and longitude. You create a geospatial index on the table, which performs a tesselation for performance; you configure the tesselation parameters. You must determine the latitude/longitude of your restaurant-seeker's location. Your command object would feed that data to a stored procedure, along with the desired radius. The stored procedure would return an enumerable set of rows to your client program.
I found this .NET wrapper which fulfills my need.
