QUESTION

Getting the distance between two geopandas data frames geometry points

Asked 2021-Mar-04 at 17:35

I am working with spatial data for the first time. I have to compare two dataframes that has lat and long details. I have converted both to GeoPandas dataframes.

When working with spatial data, you should be aware that your points coordinates are projected into a plane from a sphere. In mercator projection distance between lat lon points is in degrees, not meters. And the conversion depends on the latitude of the points, as 1 degree at the equator will be less meters than 1 degree at high latitudes.

You can check this discussion for possible solutions to this problem: https://gis.stackexchange.com/questions/293310/how-to-use-geoseries-distance-to-get-the-right-answer

To give you an example, one possibility is that you convert your geodataframe to the UTM projection that covers your region. For example Belgium intersects with UTM zone 31N EPSG:32631. Mercator projection has an epsg code EPSG:4326. To convert a GeoDataFrame/GeoSeries you need to provide the CRS when creating it:

QUESTION

Genetic Algorithm Fitness and Cross Over selection

Asked 2020-Jun-24 at 16:32

I'm attempting to use a genetic algorithm to arrange a random list of seats for a given section in a classroom so that all the groups in that classroom sit together.

Here is my current attempt, I'm unclear about the best way to improve this algorithm as this is very very early days in my GA learnings.

I'm using the Java library Jenetics, which has been pretty awesome at getting me started, here is the Engine.

One point I can see about your Engine definition is that you are using a Mutator alterer for a combinatorial problem. This causes the poor performance you have (most likely). A Mutator doesn't obey the unique element property in your chromosome. Mutating a chromosome means invalidating it, which causes a constant recreation of new chromosomes. For combinatorial problems, only SwapMutator and PartiallyMatchedCrossover are valid alterers.

I am new to Redis and was trying GEODIST function but found the result was not consistent with the result i got from some website which provide geo distance calculation function.

for example, i tried to points as

ANSWER

Answered 2017-Sep-30 at 23:45

it turns out GEOADD takes lng, lat, name rather than lat, lng, name. the first 2 arguments order was reversed.

Though I should read more carefully, the first sentence 'Adds the specified geospatial items (latitude, longitude, name) to the specified key. ' from doc https://redis.io/commands/geoadd was really confusing.
