Pauwelyn Jan 28 '17 at Pauwelyn: A character in a Python string cannot be modified, while a character in an array of characters can be.
The OP shows that replacement is desired, so the two cannot be considered equivalent. You may be thinking of other languages where strings may be modified.Geohash is a string representation of two dimensional geometric coordinates. This technique is well described at Wikipedia Geohash. It is basically, a form of Z-order curve.
Quadtree can be used to construct a string representation.

That grid code is utilized by Japan's government. Returning values are float, which is incompatibile with Geohash. Python-geohash is good for ecology. This library speeds up geohashing x3. About x23 to geodatastore in encoding, and geodatastore does not support decoding. With C extension in this library, hashing will be extremely fast: x4. If you want to use this in pure python, just copy geohash. If you want to enable C extension, build it in a normal way. Code is licensed under Apache License 2.

The Worldmap Panel is a tile map of the world that can be overlaid with circles representing data points from a query.
It can be used with time series metrics, with geohash data from Elasticsearch or data in the Table format. It can be in the Time Series format or in the Table format.
If it is in the Time Series format then the metric name needs to match a key from a list of locations. That key is usually a country code or city name. The list of locations can come from a file or an HTTP endpoint. Time Series data contains a timestamp, a metric name and a numeric value.
In other words, a typical query for a time series database. Here is some time series data from Graphite:. The Worldmap will then match the metric name target in the example data with a key field from the location data. With this example data there will be two circles drawn on the map, one for Sweden and one for the United States with values and If the data is in the Table format then it should have a column that is a geohash or two columns that contain the latitude and longitude together with the columns for the data.
Table data is tabular data with columns and rows. Here is an example of Table data from InfluxDB:. This query contains both data the value If a metric name matches a country in the list of countries then a circle will be drawn at that location. If you want to match to other data than countries or states, then you will have to provide custom location data.
The size of the circle depends on the value of the matched metric. Circle size is relative e. Use the aliasByNode function to point to the field containing the country code.
See the image below for an example of a graphite query. Example dashboard for Worldmap with Graphite queries on the Grafana play site. The Group By clause should be the country code and an alias is needed too.
Use a Group By clause on the field containing the country code and a Then by clause with Date Histogram by timestamp or corresponding date field.
If you have your own endpoint defined it must be reachable from the client side, as it is approached by client's browser. The Geo-point data type with geohash indexing in Elasticsearch can also be used as a datasource for the worldmap panel.
Grafana has a new bucket aggregate for Elasticsearch queries - Geo Hash Grid that allows grouping of coordinates. The Geo Hash Grid has a precision option where 1 is the highest level and 7 is the lowest.
The Table Data format also works with two columns for latitude and longitude instead of a geohash column. If you chose countries or table as the source of the location data then you can choose an aggregation here: avg, total etc.Fresh cap 2 walmart job description
For Graphite, be aware that the default value for Max Data Points is 1. This is to aggregate data points per country to one value in the most accurate way.
This will by default, consolidate by average. To change the consolidation, use the consolidateBy function like so:. Or just remove the 1 from the Max Data Point field and use the consolidation functions in Map Data Options though depending on the timerange and amount of data points, this will be usually less accurate due to Graphite consolidation. Three fields need to be provided by the ElasticSearch query.
