I am attempting to write a QGIS 3. I've in-lined my current code below, as well as linked to where it lives on my GitHub :. Individually, each line from the above works when tested in the python console outside of QGIS, or when each line is tested in the Field Calculator with variables substituted for actual values.

Why do I want this? What will I do with the fixed code? Open a PR to have this moved to core so everyone can use it. The expression can be introduced, as a string, as an argument of the QgsExpression function. Then, it must be evaluated in the context in which the geohash function is called.

The output is shown correctly in the preview, but when executed it returns a null value, to which the encode function returns an error. I disarmed the whole expression in parts so that it is a little less confusing. I am absolutely sure that the transformation, obtaining the centroid, and obtaining its coordinates, can be performed from functions of the imported libraries, without evaluating them as an expression but I still wouldn't know how to do it.

However, learning to evaluate expressions within the function is valid. Another option seems better to me would be to define the geohash32 function with two parameters:.

I'm sorry if I'm confusing functions with objects, methods or classes. Take this answer as a beginner's effort. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered.

I'm trying to get the bounding box x,y coordinates of geohashes using Python's geohash module. I'm able to successfully read in the geohashes and get their centroid, but when I try to use the geohash.

Here's code:. I'm able to successfully print the lat long pairs, but unable to get the bounding box. The documentation says:. When I use geohashas opposed to Geohashit says geohash is not defined.

This method returns a dictionary with keys of "s", "e", "w" and "n" which means South, East, West and North respectively. That is because you have import Geohash.

Maybe you need to change this to import geohash instead. My google search for "python geohash" turns up at least two libraries. The documentation for one shows that you need to do import Geohashbut this library does not appear to have a bbox function. The documentation for the second library has a bbox function, but requires import geohash. I suggest you figure out which library you are using and look closely at the documentation for that library in order to determine correct usage.

Geohash is a Python module that provides functions for decoding and encoding Geohashes to and from latitude and longitude coordinates. You can specify an arbitrary precision when encoding. The precision determines the number of characters in the Geohash:. The Geohash module also provides exact decoding with error margin results. In this particular case the error margins happen to be the same for both the latitude and the longitude, but this is just a co-incidence due to the precision of the Geohash and thus the number of bits used for the latitude and longitude encoding, respectively.

The Geohash encoding was originally described by Gustavo Niemeyer and the algorithm published in the Wikipedia Geohash article. Skip to content.
