the GEOADD call has the following signature:
GEOADD key longitude latitude member [longitude latitude member ...]
I cannot find in the documentation about the max size of the member (string length)?
Thanks
The size of any Redis string up to and including v4 is "limited" to 0.5GB.

Can I write around 10MB of value (JSON Data as a string) against a key (string - xyz) in Azure redis cache
Size- Standard 1 GB
Version - 4.0.14
I am able to insert 3MB of value , but while inserting 7MB of value it gives network error.
I am using StackExchange.Redis.2.1.58 client from .net console app.
From Redis website:
Strings are the most basic kind of Redis value. Redis Strings are
binary safe, this means that a Redis string can contain any kind of
data, for instance a JPEG image or a serialized Ruby object.
A String value can be at max 512 Megabytes in length.
You could put 'syncTimeout' parameter in ConnectionString like this "RedisConfiguration": {"ConnectionString": "mycache.redis.cache.windows.net:6380,password=$$$$$$$$$$$$$$$$$$=,ssl=True,abortConnect=False,syncTimeout=150000"," DatabaseNumber ": 1}. This parameter sets the "Time (ms) to allow synchronous operations", as can be seen at https://stackexchange.github.io/StackExchange.Redis/Configuration.html. I had this problem when I stored items that took more than 5 seconds to be processed, since this is the default value. You can try increasing this value using the parameter inserted in the connection string. I hope I can help you with this, regards.
Using the Redis CLI you can query a sorted set by range with an unlimited upper bound:
zrangebyscore my_key 0 +inf
Represented by the +inf as well as an unlimited lower bound: -inf. This retrieves the range from 0 to the last member.
Spring Data Redis provides an interface to this Redis command through this method signature:
Set<V> rangeByScore(K key, double min, double max, long offset, long count);
and
Set<V> rangeByScore(K key, double min, double max);
These only allow you to supply a double as the bounds.
How do you specify +inf or -inf to the bounds of ZRANGEBYSCORE using Spring Data Redis ?
The only mention of it is in the changelog so it's supported in some way but I can't find any mention of it elsewhere.
Maybe you could use Double.NEGATIVE_INFINITY and Double.POSITIVE_INFINITY to represent -inf and +inf, I've tested on my machine, which works well(with spring-boot-starter-data-redis version=2.2.4.RELEASE)
(They are both double values)
In more recent versions you can specify the range with Bound.unbounded().
Flux<V> rangeByScore(K key, Range<Double> range, Limit limit)
For example:
Range.of(Bound.inclusive(start), Bound.unbounded())
See Range class for other factory methods like leftUnbounded / rightUnbounded.
I used this with a redis version below 6.2. With 6.2+ the zrange semantics changed.
I have a netCDF file with 8 variables and 4 dimensions: latitude (dim: 26), longitude (dim:17), time (dim: a lot) and level (dim:1, pressure level). In order to use it in a specific program I need to have only 3 dimensions: latitude, longitude and time.
Is there an easy way to delete the level dimension in each variable?
I've found ncwa -a old_dim ifile.nc ofile.nc but sometimes it converts the type from short to float. When it keeps the short type the attributes "scale factor" and "add.offset" are deleted. The problem is that I want to keep the short type with scale factor and add offset.
Your method is correct, however, your input data are "packed". Repack the output file with ncpdq after averaging-out the level dimension with ncwa:
ncpdq ofile.nc ofile2.nc
and you are done. See docs here.
I have been creating an implementation where I would want to get the latitude and longitude coordinate values per each of the returned image from Panoramio.
I have seen an example where the REST call returned an object, which contained also the lat&lon values for the photo. E.g. when requesting simply first 10 top listed images.
If I now examine the default input from the Panoramio service, I atleast cannot locate the parameters lat and lon in the result?
Anyone knows why this is and how could I get both the images and the latitude longitude values as supposed?

I want using GPS data (I got it from $GPRMC) in an desktop application(that uses from mappoint 2009). I get the latitude & longitude, but when I check these points on map, I see the result is incorrect (for example My Data is: 43.412 N, 79.369 W ; but the correct point is: 43.686 N, 79.616 W ).
I guess, I must use a correction method before use; I try "Projection method" like "Miller" or "Mercator", but those aren't effective.
Can anyone guide me?
Are you using the same coordinate systems? E.g. WGS-84 or something else?
