kandi X-RAY | geo Summary

geo is a Java library typically used in Database, SQL Database, DynamoDB applications. geo has build file available, it has a Permissive License and it has high support. However geo has 6 bugs and it has 1 vulnerabilities. You can download it from GitHub.

Databases of events at specific times occurring at specific places on the earth’s surface are likely to be queried in terms of ranges of time and position. One such query is a bounding box query involving a time range and position constraint defined by a bounding lat-long box. The challenge is to make your database run these queries quickly. Some databases may either not support or suffer significant performance degradation when large datasets are queried with inequality conditions on more than one variable. For example, a search for all ship reports within a time range and within a bounding box could be achieved with a range condition on time combined with a range condition on latitude combined with a range condition on longitude ( combined with = logical AND). This type of query can perform badly on many database types, SQL and NoSQL. On Google App Engine Datastore for instance only one variable with inequality conditions is allowed per query. This is a sensible step to take to meet scalability guarantees.

            C# get html from url. Error (429) unknown
            Asked 2021-Jun-15 at 16:52

            I am using the following code to retrieve the html code from a url. It is working fine for a url as:

            "The remote server returned an error: (429) unknown.'"

            What could be the error or how to get more info about the error?

            It's no longer possible to get the source code of google services without an API because specifically the trends service makes many calls when you visit only hence the error 429.

            Do not waste your time digging in proxies, browser emulation or bots none will work. The best way is to use Google API for c# .

            error using lapply on tibble convert from double to logical
            Asked 2021-Jun-14 at 16:50

            Edit: It looks like this is a known issue with the "cascade" method. Results that return NA values after the first attempt don't like being converted to doubles when subsequent methods return lat/lons.

            Data: I have a list of addresses that I need to geocode. I'm using lapply() to split-apply-combine, which works, but very slowly. My thought to split (further)-apply-combine is returning errors about dim names and sizes that are confusing to me.

            Answered 2021-Jun-13 at 12:54

            When having issues like this you should start by checking two things:

            First whether the css file that is being loaded actually includes your rules, because your browser may have a cached version stored and simply avoids loading it again.

            If that is ok, then you should check whether or not your rules are being overwritten by any other rule included, that may be more specific or flagged as!important

            The web inspector can help in both cases!



            Flutter Firebase Firestore List Data Saving Cannot Recall Index as
            Asked 2021-Jun-13 at 10:59

            When I'm doing activity from a user in a project, I get the instant location and save it with firebase and firestore. But when I call back the query, I get everything I saved in the list. I just want it to come as an index index. For example 1-"kosum1". How can I do that?



            Answered 2021-Jun-13 at 10:59

            You can convert the List to a Map of its index to the list value using the List.asMap() method.

            The map uses the indices of this list as keys and the corresponding objects as values.

            Is there a way to use 'Geo-polygon' query inside elasticsearch ingest pipeline?
            Asked 2021-Jun-12 at 07:49

            I want to use the elasticsearch Geo-polygon query ( or Geo-shape query inside an ingest pipeline and I've been thinking how to do it - as there is no such processor as query processor and the example for the geo polygon is with this type of query.

            The reason for me trying to use this tool is to enrich documents which's country location is null, by checking their lat and lon fields and determining which country the doc is from.

            Is there anyway this could be done in an ingest pipeline? Or any other way to determine a position by lat and lon within geo shapes in a pipeline?



            Answered 2021-Jun-12 at 07:49

            Answer for enrichment of the data with geo-based policy:

            Also note that there is a feature suggestion pending in Elastic Github in order to exclude the geo-shape used for the enrichment, so there will be no need for a second pipeline to delete the field.



            Ag-grid React column shifts that uses valueGetter when rowData fetched from server
            Asked 2021-Jun-11 at 14:48

            Whenever I fetch data from any server to display it in ag-grid, ag-grid does not maintain the column order for the column that uses valueGetter to choose the value and puts that column automatically at the end.

            The problem is replicated in the following code sandbox link: as a minimum reproducible example

            The data received from the server is in the following format



            Answered 2021-Jun-11 at 14:48

            Since the column does not have a field supplied, I'd recommend either supplying a field or colID to the column. This would be the simplest approach without having to use any API calls to move the column:

            "For" loop with column names as index
            Asked 2021-Jun-10 at 11:01

            I would like to create a loop in which the index is given by the column names of a dataframe. The idea is to select one column at a time and create a map based on the data in that column. I need i being the column name, as it identifies the name of the variable and I'll use that as part of the title of the map. However, I do not seem to be able to associate my index i to the name of the column. My code goes as follows:



            Answered 2021-Jun-10 at 10:55

            In base R, you can either select the columns by position or by name, you can't combine them both in one command. If you use dplyr::select you can select columns by name and position in the same command.

            So here are your options -

            The structure of responses differ and you need to actually modify a little for your v2.

            Update your loop condition.

            • obj_data in v2 contains additional meta, thus you need to get the length of instead of just obj_data
